PHP - Ajax Getting Data
Hello friends, i need a help i have index.php and response.php and i am try to get data from response.php per once second and i am getting data in script tag. I want to use incoming data in php tag and i will parse the data however i cant do that anyone can help me ? Similar TutorialsHello, I've been trying this for hours now, looking at different examples and trying to change them to work for me, but with no luck... This is what I am trying to do: I have a simple form with: - 1 input field, where I can enter a number - 1 Submit Button When I enter a number into the field and click submit, I want that number to be send to the php file that is in the ajax call, then the script will take that number and run a bunch of queries and then return a new number. I want that new number to be used to call the php script via ajax again, until no number is returned, or something else is returned like the word "done" or something like that, at which point is simply makes an alert or populated a div with a message... The point is, that depending on the number entered it could take up to an hour to complete ALL the queries, so I want the script that is called to only run a fixed amount of queries at a time and then return the number it is currently at (+1), so that it can continue with the next number when it is called again. I would like to use jquery, but could also be any other way, as long as I get this to work. I already have the php script completed that needs to be called by the ajax, it returns a single number when being called. Thank you, vb I am trying to write a basic Private Messaging script.
I have my main page which lists all messages that have been received. I then want to click on an href link to run an ajax query to bring information in from another .php file which shows the content of the selected message.
But I can't fathom out how to do this with an href. First off, is it possible? If so, can anyone tell me what I am doing wrong?
The relevant script is:
privatemessage.php:
<?php
$query2 = DB::getInstance()->query("SELECT
c.id as cid, c.title, c.time,
m.id as membersid, m.username,
m.member_first_name, m.member_last_name
FROM conversation as c, members as m
WHERE ((c.member1='{$memberid}'
and c.read1='Yes' and c.removed1='No'
and m.id=c.member2)
OR (c.member2='{$memberid}' and c.read2='Yes'
and c.removed2='No' and m.id=c.member1))
GROUP BY m.id ORDER BY m.id DESC");
?>
<table>
<tr>
<td align="left">
<?php echo htmlentities($result2->member_first_name); ?>
<?php echo htmlentities($result2->member_last_name); ?>
<?php echo "("; echo htmlentities($result2->username); echo ")"; ?>
</td>
<td align="right">
<?php echo timeAgo(strtotime($result2->time)); ?>
</td>
</tr>
<tr>
<td colspan="2" align="left">
<form action="" method="post">
<?php echo "Subject: "; ?>
<?php echo "<input type='hidden' name='id' id='id' value='{$result2->cid}'>"; ?>
<a href="#$result2->cid" onClick="showMessages(this.value)"><?php echo htmlentities($result2->title); ?>
</form>
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="js/readmessage.js"></script>
</td>
</tr>
My readmessage.js code is:
function showMessages(str)
{
if (str=="")
{
document.getElementById("txtMessage").innerHTML="";
return;
}
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("txtMessage").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","readmessage.php?q="+str,true);
xmlhttp.send();
}
And my readmessage.php code is:
<?php
require 'core/memberinit.php';
$member = new Member();
include 'timeago.php';
$memberid = $member->data() ->id;
if(isset($_GET['q'])) {
$q = html_entity_decode($_GET['q']);
$req1 = DB::getInstance()->query("SELECT title, member1, member2 FROM conversation WHERE id='{$q}' AND id2='1'");
foreach ($req1->results() as $dn1)
if($req1->count()==1)
{
if(($dn1->member1=='{$memberid}') or ($dn->member2=='{$memberid}'))
{
if($dn1->member1=='{$memberid}')
{
DB::getInstance()->query("UPDATE conversation SET read1='Yes' where id='{$q}' and id2='1'");
$user_partic = 2;
} else {
DB::getInstance()->query("UPDATE conversation SET read2='Yes' where id='{$q}' and id2='1'");
$user_partic = "1";
}
$req2 = DB::getInstance()->query("SELECT conversation.time, conversation.message,
members.id as userid, members.username, members.member_first_name, members.member_last_name
FROM conversation, members
WHERE conversation.id='{$id}' AND members.id=conversation.member1
ORDER BY conversation.id2");
if(isset($_POST['message']) and $_POST['message']!='')
{
$message = $_POST['message'];
if(get_magic_quotes_gpc())
{
$message = stripslashes($message);
}
$message = $string(nl2br(htmlentities($message, ENT_QUOTES, 'UTF-8')));
if( DB::getInstance()->query("INSERT into conversation
(id, id2, title, member1, member2, message, time, read1, read2)
VALUES('{$q}', '{(intval($req2->id2)+1)}', '', '{$memberid}', '', '{$message}', '.time().', '', '')")
and
DB::getInstance()->query("UPDATE conversation SET read'{$user_partic}'='Yes' WHERE id='{$q}' AND id2='1'"));
}
echo "<h4>";
echo $dn1->title;
echo "</h4><br><br>";
echo "<table><col width='150px'><col width='50px'><col width='150px'>";
echo "<tr><th>Member</th><th> </th><th>Message</th></tr>";
foreach ($req2->results() as $dn2)
{
echo "<tr><td>";
echo $dn2->members.member_first_name;
echo $dn2->members.member_last_name;
echo " (";
echo $dn2->members.username;
echo ") </td><td></td><td>";
echo timeAgo(strtotime($dn2->time));
echo "<br>";
echo $dn2->message;
echo "</td></tr>";
}
echo "</table>";
}
}
}
?>
However, just to try and find where the error lies, I have tried the following code for my readmessage.php file:
<?php
require 'core/memberinit.php';
$member = new Member();
include 'timeago.php';
$memberid = $member->data() ->id;
if(isset($_GET['q'])) {
$q = intval($_GET['q']);
echo $q;
}
?>
Which always returns a "0" reply - which says to me that my files are talking, but that the id isn't being carried across.
Anybody got any suggestions?
Many thanks for any help offered.
So I have an AJAX call that I'm using to POST 1 variable to a PHP script I have on a separate server. The PHP takes this variable and returns data based off of what the variable is. This works on all browsers except IE9 and below. IE9 returns data but it's an error saying the variable is missing which to me shows that it isn't sending the data. Below I have the AJAX call I'm making:
(function (jQ) { var inviteID = '00000000000'; jQ.ajax({ url: 'www.example.com/test.php', type: 'POST', dataType: 'json', cache: false, data: { classID: inviteID }, error: function (data, status, error) { jQ('.statusField').append('Failu ' + data + status + error); }, success: function (data, status, error) { jQ('.statusField').append('Success: ' + data); } }); })(jQuery); And below I have the PHP script that's being used: <?php //first POST to grab token function runPost($classID) { $postdata = array( 'username' => 'username', 'password' => 'password' ); //open connection $ch = curl_init(); //set the url, POST data curl_setopt($ch, CURLOPT_URL, "https://www.example.com/login"); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($postdata)); curl_setopt($ch, CURLOPT_USERAGENT, 'example'); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //execute post $result = curl_exec($ch); //close connection curl_close($ch); list($message, $time, $token, $userID) = split(',', $result); list($one, $two, $three, $four, $five) = split('\"', $token); $four = json_encode($four); $four = str_replace('"','',$four); $secondaryPostData = array( 'token' => $four, 'data' => array( 'invitationID' => $classID )); //open connection $chu = curl_init(); //set the url, POST data curl_setopt($chu, CURLOPT_URL, "https://www.example.com/classID"); curl_setopt($chu, CURLOPT_POST, 1); curl_setopt($chu, CURLOPT_POSTFIELDS, json_encode($secondaryPostData)); curl_setopt($chu, CURLOPT_USERAGENT, 'example'); curl_setopt($chu, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); curl_setopt($chu, CURLOPT_RETURNTRANSFER, 1); //execute post $secondResult = curl_exec($chu); //close connection curl_close($chu); return json_encode($secondResult); } //Grab classID from javascript echo runPost(trim($_POST['classID'])); ?> Again, this works fine in everything except IE. I've tried using just $.post and even XDomainRequest() and get the same result. The network console in IE shows that the Request body does have the classID in it, but I'm guessing it's just not sending the data to the PHP script. I don't know if I'm missing something that IE needs to send this to the PHP script but any help with this would be GREATLY appreciated. I am retrieving Google Books info in JSON format and displaying it inside a div. I would like to send the contents of this div (name, title, description) to my database using Ajax.
Currently only the ISBN field sends because I have it declared as a variable. However my question is, how do I send the other fields (name, title, author). How do I declare these also, I'm not sure what format they need to be in etc.
My JS
$(document).ready(function() {
$('#submit').click(function(ev) {
ev.preventDefault();
var isbn = $('#isbn_search').val(); //get isbn direct from input
var url='https://www.googleapis.com/books/v1/volumes?q='+isbn;
$.getJSON(url,function(data){
$.each(data.items, function(entryIndex, entry){
var html = '<div class="results well">';
html += '<h3>' + entry.volumeInfo.title + '</h3>';
html += '<div class="author">' + entry.volumeInfo.authors + '</div>';
html += '<div class="description">' + entry.volumeInfo.description + '</div>';
});
});
});
});
My Ajax;
$.ajax({
type: 'POST',
url: 'addIsbnScript.php',
data: {
'isbn' : isbn,
'title' : title
'subtitle' : subtitle,
'authors' : authors,
'description' : description
},
success: function () {
$.growl({
message: " Record added"
});
}
});
Note, if i manually set the vars like below they all do successfully send to my database, so I know my query is working ok
var title = "some text", var author = "some text", Var description = "some text"Thanks in advance for any help, newbie here (incase it wasn't obvious!). J Hi Everyone,
I am struggling with a pdf.
On our server I get the pdf as a byte array from the database, which I then build up in a StreamingOutput object and return as a pdf file. This is done using java using JAX-RS service.
Now when I open the path/link in my browser(chrome/firefox) the pdf opens in the browser. So this means my backend is working.
On my webapp I want to use $.ajax to download the pdf and view it in an Iframe or embed it in an <embed> or <object> tag. I need to do this as the service call is actually under username and password, and we do not create a session between the browser and the server - there is a long explanation for this.
I saw the option to use http://[username]:[password]@www.myserver.com/... but this was dropped by most browsers. This is why I am trying ajax.
Now in my ajax call I do receive the pdf in the success function as:
%PDF-1.4....This open the browser's pdfviewer correctly and every thing, but the pdf only returns blank pages. The Base64 is a java object that I found on the internet. But I have tried it without the base64 but still now luck. Here is my success function from my ajax call.
success: function(data, status, xhr) {
var pdfText = Base64.encode(xhr.responseText);
var url = "data:application/pdf;base64," + escape(pdfText);
var html = '<embed width=100% height=600'
+ ' type="application/pdf"'
+ ' src="' + url + '">'
+ '</embed>';
$("div.inner").html("");
$("div.inner").append(html);
},
II am new to jscript and AJAX and have a problem that I need to solve.
I have a form on which I need to input the RGB values of a color that will be used in the next PHP file.
I have choosen a color chooser written in jscript called JS-Color.
There are a number of pre-written scripts for choosing the color, of which I have used the following:
<script type="text/javascript" src="jscolor/jscolor.js"></script>
R<input id="red" size="5"> G<input id="grn" size="5"> B<input id="blu" size="5"> - - -
H<input id="hue" size="5"> S<input id="sat" size="5"> V<input id="val" size="5">
<p> Choose any color: <input class="color" id="myColor" onchange="
document.getElementById('red').value = this.color.rgb[0]*100 + '%';
document.getElementById('grn').value = this.color.rgb[1]*100 + '%';
document.getElementById('blu').value = this.color.rgb[2]*100 + '%';
document.getElementById('hue').value = this.color.hsv[0]* 60 + '°';
document.getElementById('sat').value = this.color.hsv[1]*100 + '%';
document.getElementById('val').value = this.color.hsv[2]*100 + '%';">
I am trying to work out how to use this to get the 3 values that I can post in a form.
Looking at the internet, I have found that AJAX is the easiest way to POST from jscript.
I have attempted to write some script, but I'm sure I'm way off the mark.
Here is my attempt:

Which is the variable that I can use?
Is it this.color.rgb[0]*255; for example?
I have created a variable $red etc, but it does not even open the test_input.php file.
None of the examples I have seen on the internet relate to the task I am trying to figure out.
Can anyone advise me?
//my controller
<?php
namespace App\Http\Controllers;

$employee = DB::table('employee')->orderBy('id','desc')->get();
$department = DB::table('department')->orderBy('id','desc')->get();
return view('index', ['employee' => $employee , 'department' => $department]);
}
}
//my routes
Route::get('index','homeController@index');
//my view using blade temmplating engine

Edited April 26, 2019 by aveeva Hello everyone, I begin in everything web related but I have been programming for years. I tried to code something simple : small Mysql DB (works fine) and to begin a search bar to browse data. I adapted a code that I understood provided here : https://www.cloudways.com/blog/live-search-php-mysql-ajax/. Base principle is simple : as you type in your query, it will pass the text to script.js that will forward this request to ajax.php file. In the ajax.php, a javascript function named “fill()” will pass the fetched results. This function will also display the result(s) into “display” div in the “search.php” file. The problem is that when I type anything it displays, below the search bar, at the moment I type a character: Quote
'; //Fetching result from database. while ($Result = MySQLi_fetch_array($ExecQuery)) { ?> ")'>
instead of the actual answer from my database (no error in the browser console). I tested the SQL query + the user I provide and everything seems fine. Any clue what could be the root cause ? I strongly suspect a mistake in the code as I already corrected one (script.js instead of scripts.js) but I really cannot figure out where. Thanks in advance,
problematic code (ajax.php):
<?php
//Including Database configuration file.
include "db.php";
//Getting value of "search" variable from "script.js".
if (isset($_POST['search'])) {
//Search box value assigning to $Name variable.
$Name = $_POST['search'];
//Search query.
$Query = "SELECT Name FROM search WHERE Name LIKE '%$Name%' LIMIT 5";
//Query execution
$ExecQuery = MySQLi_query($con, $Query);
//Creating unordered list to display result.
echo '
<ul>
';
//Fetching result from database.
while ($Result = MySQLi_fetch_array($ExecQuery)) {
?>
<!-- Creating unordered list items.
Calling javascript function named as "fill" found in "script.js" file.
By passing fetched result as parameter. -->
<li onclick='fill("<?php echo $Result['Name']; ?>")'>
<a>
<!-- Assigning searched result in "Search box" in "search.php" file. -->
<?php echo $Result['Name']; ?>
</li></a>
<!-- Below php code is just for closing parenthesis. Don't be confused. -->
<?php
}}
?>
</ul>
here my sample code
<form>
<input id="query" type="text" name="query" placeholder="search here..." autocomplete="off">
<button type="submit" value="query" >search</button>
<div class="sugbx"></div>
</form>
//php code, assume we already run a whole php code
......
<ul class="list-group list-unstyled" style="cursor:pointer; color: #191919; position:absolute; top:12px;">
<?php
foreach($query as $movie) {
?>
<li class="list-group-item" onClick="searchValue('<?php echo $movie["movie_name"]; ?>'),;"><?php echo $movie["movie_name"]; ?></li>
<?php } ?>
</ul>
<?php } ?>
//ajax here
$('#search').keyup(function(){
$.ajax({
type: 'GET',
url: 'phpcode.php',
data:'query='+$(this).val(),
success: function(data){
$('.sugbx').show();
$('.sugbx').html(data);
}
});
});
function searchValue(val) {
$('#query').val(val);
$('.sugbx').hide();
}
//ajax
the input accept the value only after selecting one of the listed value on the suggesstion box and then i have to click the submit button the problem is, how to submit the value accepted when a list is clicked I had this working, but when I try and get fancy and use AJAX the data doesn't display. I think this is a PHP problem though. My code for the select form including AJAX code Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-GB"> <head> <title>AJAX Example</title> <link rel="stylesheet" type="text/css" href="Form.css" media="screen" /> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $(document).ready(function(){ $("tr:odd").addClass("odd"); }); </script> <script type="text/javascript"> function showPlayers(str) { var xmlhttp; if (str=="") { document.getElementById("DataDisplay").innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); else {// code for IE6, IE5 } xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("DataDisplay").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","Query.php?category_id="+str,true); xmlhttp.send(); } </script> </head> <body> <h1">AJAX Example</h1> <?php #connect to MySQL $conn = @mysql_connect( "localhost","username","pw") or die( "You did not successfully connect to the DB!" ); #select the specified database $rs = @mysql_SELECT_DB ("MyDB", $conn ) or die ( "Error connecting to the database test!"); ?> <form name="sports" id="sports"> <legend>Select a Sport</legend> <select name="category_id" onChange="showPlayers(this.value)"> <option value="">Select a Sport:</option> <?php $sql = "SELECT category_id, sport FROM sports ".

When I echo out the SQL the result is Code: [Select] SELECT * FROM sports INNER JOIN players ON sports.category_id = players.category_id WHERE players.category_id = '' so the category_id is not being selected properly and that is the primary key/foreign key in the MySQL table which connects the JOIN. Right now I redirect to index page after I delete a record. However I am looking to make it so that I can delete a record without redirecting the page. I know this can be accomplised using Ajax. I have spent countless hours before trying to make it work, but it did not work.
So here is a basic setup I created. Can you please update it with ajax code so that I can see how it's done properly?
<!DOCTYPE HTML> <html lang="en"> <head> <meta charset="UTF-8"> <title>Home Page</title> </head> <body> <div class="record" > <a href="record.php?id=<?php echo $record_id ?>"><?php echo $record_name; ?></a> <div class="delete-record"> <a href="delete.php">Delete Record</a> </div> </div> </body> </html> Edited by man5, 18 August 2014 - 08:55 PM. Now I'm having this strange issue with my website I'm currently working on a tester system and I've encountered a problem that I'm unable to find the issue, tho I'm thinking my ajax php part of the script to be the thing causing it even tho it seems strange that it would cause it. The first part which is connected to where the problem occurs is the echo"<form>"; and from there, It should take you to index.php?page=tester&select=answer, now that is where it in the browser goes there tho it still shows the page stuff from the last page which is index.php?page=tester&select=applications, so it's like showing both &select=answer and &select=applications on the same page. <?php $q=$_GET["q"]; include'../config/connection.php'; $result = mysql_query("SELECT * FROM applications WHERE id = '$q'"); echo "<center><table border='1'> <tr> <th>Account Name</th> <th>Character Name</th> <th>Gender</th> <th>Skin Color</th> </tr>"; $row = mysql_fetch_array($result); echo "<tr>"; echo "<td>" . $row['name'] . "</td>"; echo "<td>" . $row['charactername'] . "</td>"; echo "<td>" . $row['gender'] . "</td>"; echo "<td>" . $row['race'] . "</td>"; echo "</tr></table></center>"; echo"<br/>"; echo"<table><tr> <th>Description</th> <th>Metagaming</th> <th>Powergaming</th></tr>"; echo"<tr>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['description']."</textarea></td>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['mg']."</textarea></td>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['pg']."</textarea></td>"; echo"</tr></table><table><br/><center><h1>Answer</h1><br/><form action='index.php?page=tester&select=answer' method='post'>"; echo"<textarea name='why' style='height:10em; width:60em;'></textarea><br/>"; echo"<input type='submit' name='answer' value='Accept' /><a/>"; echo"<input type='submit' name='answer' value='Decline' /></center>"; echo"<input type='hidden' name='id' value='$q'/>"; echo"</form></table>"; ?> Now on &select=answer it included a page which the script of that include consist of the stuff below, it outputs that the query was successfully, and all that. <? if(!empty($_POST['why'])) { $why = mysql_real_escape_string($_POST['why']); $answer = trim($_POST['answer']); $id = $_POST['id']; if($answer == "Accept") { $query1 = mysql_query("UPDATE characters SET accepted = '1' WHERE id = '".$id."'"); echo"Successfully accepted"; $answer = 1; } elseif($answer == "Decline") { echo"Successfully declined"; $answer = 0; } $query = mysql_query("UPDATE applications SET answer = '$why' AND tester = '".$_COOKIE['Username']."' AND accepted = '$answer' AND answered = '1' WHERE cid = '".$id."'") or die('Could not connect: ' . mysql_error()); if($query) { echo"<br/>Query went through without problems"; header("Refresh: 5;url=index.php?page=tester"); } } ?> This is the ajax part javascript of it which gets the information for index.php?page=tester&select=applications Code: [Select] <script type="text/javascript"> function showApplication(str) { if (str==""||str==0) { document.getElementById("txtHint").innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("txtHint").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","tester/applications.php?q="+str,true); xmlhttp.send(); } </script>If you need any more information feel free to ask for it. Thanks in advance. As the title say, I can not for the life of me get the "$bank" content to display, no matter HOW much I try... Does anyone see any errors. I am sooooooo wiped out at this! main page <? $body = ' <script type="text/javascript" src="change-content.js"></script> <div id="addSold"> <form action="'.$_SERVER['REQUEST_URI'].'" method="post" name="form" autocomplete="off"> <fieldset id="Vehicle"> <legend>Vehicle</legend> <ul> <li><label for="Year">Year</label>'.$Year.'</li> <li><label for="Make">Make</label>'.$Make.'</li> <li><label for="Model">Model</label>'.$Model.'</li> <li><label for="Trim">Trim</label><input type="text" name="Trim" id="Trim" size="10" value="'.$trim.'" disabled="disabled"></li> </ul> <ul> <li><label for="Mileage">Mileage</label><input type="text" name="Mileage" id="Mileage" size="5" maxlength="6" value="'.$row['mileage'].'"></li> <li><label for="VIN">VIN</label><input type="text" name="VIN" id="VIN" size="23" maxlength="17" value="'.$row['vin'].'" disabled="disabled"></li> <li><label for="Color">Color</label>'.$Exterior.'</li> </ul> </fieldset> <fieldset id="Deal"> <legend>Deal</legend> <ul> <li> <label for="soldDte1">Date</label> <input type="text" name="soldDte1" id="soldDte1" size="1" maxlength="2" onkeyup="return autoTab(this, 2, event)" value="08"> / <input type="text" name="soldDte2" id="soldDte2" size="1" maxlength="2" onkeyup="return autoTab(this, 2, event)" value="30"> / <input type="text" name="soldDte3" id="soldDte3" size="1" maxlength="2" value="'.$year.'"> <a href="#"><img id="date_'.$row[stock].'" src="images/Icons/dateOff.png" onfocus="this.select();lcs(this)" onmouseover="MM_swapImage(\'date_'.$row[stock].'\',\'\',\'images/Icons/dateOn.png\',1)" onmouseout="MM_swapImgRestore()" alt="Choose Date"></a> </li> <li> <label for="salesman">Salesman</label> <select name="salesman" id="salesman"> <option></option> '.$salesmen.' </select> </li> </ul> <ul> <li> <label for="dealType">Deal Type</label> <select name="dealType" class="select-content" onchange="getFile(this.value)"> <option></option> <option value="AL">Auto Loan</option> <option value="Cash">Cash</option> <option value="CAC">Credit Acceptance</option> <option value="IH">In House</option> <option value="SAL">Sensible Auto</option> </select> </li> <li> <label for="tradeDrop">Trade</label> <select name="tradein" id="tradeDrop" onchange="show_hide_trade(this.value);"> <option value="No">No</option> <option value="Yes">Yes</option> </select> </li> </ul> </fieldset> <div id="Bank" class="view">'.$bank.'</div> </form> </div> '; ?> get_Bank.php <? if ($_GET['dealType'] == "AL") { $bank = ' <fieldset id="AL"> <legend>Auto Loan Figures</legend> <ul> <li><label for="price">Price</label><input type="text" name="price" id="price" class="price" size="7" onchange="currency(this)"></li> <li><label for="down">Down</label><input type="text" name="down" id="down" class="price" size="6" onchange="currency(this)"></li> <li><label for="tax">Tax</label><input type="text" name="tax" id="tax" class="price" size="6" onchange="currency(this)"></li> <li><label for="reg">Plates</label><input type="text" name="reg" id="reg" class="price" size="4" onchange="currency(this)"></li> <li><label for="gap">Gap</label><input type="text" name="gap" id="gap" class="price" size="4" onchange="currency(this)"></li> </ul> <ul> <li> <label for="pymtNum">--------------- Payment ---------------</label> <input type="text" name="pymtNum" id="pymtNum" size="3" maxlength="3" onkeyup="return autoTab(this, 3, event)"> @ <input type="text" name="pymtAmnt" id="pymtAmnt" class="price" size="5" onchange="currency(this)"> per <select name="pymtType"> <option value="Weekly" selected="selected">Week</option> <option value="Monthly">Month</option> </select> </li> <li><label for="APR">APR</label><input type="text" name="APR" id="APR" class="rate" size="6" value="19.00"></li> </ul> </fieldset> '; } elseif ($_GET['dealType'] == "CAC") { $bank = ' Credit Acceptance stuff goes here '; } else { $bank = 'You must choose a bank before continuing'; } ?> change-content.js Code: [Select] window.onload = init; // finds all <select> tags will class="select-content" and activates function function init() { var sel = document.getElementsByTagName("select"); for (var i=0; i<sel.length; i++){ if (sel[i].className == "select-content") { sel[i].onchange = getFile; } sel[i].selectedIndex = 0; } } function getFile (url) { var url = "AJAX/get_Bank.php?dealType="+ this.value; if (window.XMLHttpRequest) {xmlhttp=new XMLHttpRequest();} else {xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");} xmlhttp.open("GET",url,false); xmlhttp.send(); // a loop that looks through all <div>s on the page // and then replaces the id with the value and gets that file var divs = document.getElementsByTagName("div"); for (var i=0; i<divs.length; i++) { if(divs[i].id == "bank") { divs[i].id = this.value; divs[i].innerHTML=xmlhttp.responseText; } } } Am new here - looks like a great foru! I would sincerely appreciate any help anyone can give me. I have been trying to solve my problem for hours and I am not having any luck, so I thought I would post and see if anyone can help. I am very stuck and am not making much progress on this project, and I am certain the answer is very simple. I am constructing a form to collect data for a specialized purpose. The form and program actually work for its intended function, but I am trying to enhance the user experience by preventing customers from having to reenter all of their data should there be a problem with any of the data submitted. I have been able to do that with the contact form portion, but what I am having trouble with is the portion which has as many as 400 possible entries. So, in a nutshell, if the customers contact data is incomplete or in error, the form will ask them to return to the page and correct things. The previous data entered has been saved in the session and the input value will equal the previous entry. i.e. <tr> <td align="right" class="infoBox"><?php echo ENTRY_EMAIL_ADDRESS; ?></td> <td align=left><?php echo "<input type=text name='cemail' value=\"$cemail\" size=35 maxlength=35>" ?></td> </tr> Works perfectly, all well and good there. On the other 400 more or less entries, I am having a difficult time tweaking the string concatenation to work to achieve similar results. There are 4 columns each with $points entries asking for a dimension in either feet or inches. The <input name=> is one of ptaf,ptai,ptbf,ptbi, appended programatically with the corresponding row number or data point. i.e. "ptaf1", "ptai1", etc... This is produced by the example below and works perfectly also. <?php { $points=100; $i=1; while ($i <= $points) {echo ' <tr><td align="center" width="6"><b> ' .$i . '</b></td> <td align="right" NOWRAP>A' .$i . ' (ft) <input type="text" name="ptaf'.$i.'" size=4 maxlength=3> </td> <td align="right" NOWRAP>A' .$i . ' (in) <input type="text" name="ptai'.$i.'" size=4 maxlength=4> </td> <td align="right" NOWRAP>B' .$i . ' (ft) <input type="text" name="ptbf'.$i.'" size=4 maxlength=3> </td> <td align="right" NOWRAP>B' .$i . ' (in) <input type="text" name="ptbi'.$i.'" size=4 maxlength=4> </td> '; $i++; } } ?> I am trying to add <input value=$ptai.$i> for each field but as I mentioned I am not having any luck. It seems as if I have tried every combination imagineable, but still no luck. My head is spinning! The closest I seem to have gotten was with this: <td align="right" NOWRAP>A' .$i . ' (ft) <input type="text" size=6 maxlength=3 name="ptaf'.$i.'" value="' . "$ptaf" . $i . '" ></td> But line 17 for example returns this: <input type="text" value="17" name="ptaf17" maxlength="3" size="6"> To recap, I am trying to have the value set to whatever the customer may have entered previously. Again, I would most appreciate any help anyone can give me. If you need clarification on anything please let me know. Thanks AJ Hello to all, I have problem figuring out how to properly display data fetched from MySQL database in a HTML table. In the below example I am using two while loops, where the second one is nested inside first one, that check two different expressions fetching data from tables found in a MySQL database. The second expression compares the two tables IDs and after their match it displays the email of the account holder in each column in the HTML table. The main problem is that the 'email' row is displayed properly while its while expression is not nested and alone(meaning the other data is omitted or commented out), but either nested or neighbored to the first while loop, it is displayed horizontally and the other data ('validity', 'valid_from', 'valid_to') is not displayed.'
Can someone help me on this, I guess the problem lies in the while loop? <thead> <tr> <th data-column-id="id" data-type="numeric">ID</th> <th data-column-id="email">Subscriber's Email</th> <th data-column-id="validity">Validity</th> <th data-column-id="valid_from">Valid From</th> <th data-column-id="valid_to">Valid To</th> </tr> </thead> Here is part of the PHP code:
<?php
while($row = $stmt->fetch(PDO::FETCH_ASSOC))
{
echo '
<tr>
<td>'.$row["id"].'</td>
';
while ($row1 = $stmt1->fetch(PDO::FETCH_ASSOC)) {
echo '
<td>'.$row1["email"].'</td>
';
}
if($row["validity"] == 1) {
echo '<td>'.$row["validity"].' month</td>';
}else{
echo '<td>'.$row["validity"].' months</td>';
}
echo ' <td>'.$row["valid_from"].'</td>
<td>'.$row["valid_to"].'</td>
</tr>';
}
?>
Thank you. Hi, after banging my head against the wall for a while thinking this would be a simple task, I'm discovering that this is more complicated than I thought. Basically what I have is a link table linking together source_id and subject_id. For each subject there are multiple sources associated with each. I had created a basic listing of sources by subject... no problem. I now need a way of having a form to create an ordered list in a user-specified way. In other words, I can currently order by id or alphabetically (subject name lives on a different table), but I need the option of choosing the order in which they display. I added another row to this table called order_by. No problem again, and I can manage all of this in the database, however I want to create a basic form where I can view sources by subject and then enter a number that I can use for sorting. I started off looping through each of the entries and the database (with a where), and creating a foreach like so (with the subject_id being grabbed via GET from the URL on a previous script) Code: [Select] while($row = mysqli_fetch_array($rs)) { //update row order if (isset($_POST['submit'])) { //get variables, and assign order $subject_id = $_GET['subject_id']; $order_by = $_POST['order_by']; $source_id = $row['source_id']; //echo 'Order by entered as ' . $order_by . '<br />'; foreach ($_POST['order_by'] as $order_by) { $qorder = "UPDATE source_subject set order_by = '$order_by' WHERE source_id = '$source_id' AND subject_id = '$subject_id'"; mysqli_query($dbc, $qorder) or die ('could not insert order'); // echo $subject_id . ', ' . $order_by . ', ' . $source_id; // echo '<br />'; } } else { $subject_id = $_GET['subject_id']; $order_by = $row['order_by']; $source_id = $row['source_id']; } And have the line in the form like so: Code: [Select] echo '<input type="text" id="order_by" name="order_by[]" size="1" value="'. $order_by .'"/> (yes I know I didn't escape the input field... it's all stored in an htaccess protected directory; I will clean it up later once I get it to work) This, of course, results in every source_id getting the same "order_by" no matter what I put into each field. I'm thinking that I need to do some sort of foreach where I go through foreach source_id and have it update the "order_by" field for each one, but I must admit I'm not sure how to go about this (the flaws of being self-taught I suppose; I don't have anyone to go to on this). I'm hoping someone here can help? Thanks a ton in advance I have two tables. Table Name:Users Fields: User_name user_email user_level pwd 2.Reference Fields: refid username origin destination user_name in the users table and the username field in reference fields are common fields. There is user order form.whenever an user places an order, refid field in reference table will be updated.So the user will be provided with an refid Steps: 1.User needs to log in with a valid user id and pwd 2.Once logged in, there will be search, where the user will input the refid which has been provided to him during the time of order placement. 3.Now User is able to view all the details for any refid 3.Up to this we have completed. Query: Now we need to retrieve the details based on the user logged in. For eg: user 'USER A' has been provided with the referenceid '1234' during the time of order placement user 'USER B' has been provided with the referenceid '2468' during the time of order placement When the userA login and enter the refid as '2468' he should not get any details.He should get details only for the reference ids which is assigned to him. <?php session_start(); if (!$_SESSION["user_name"]) { // User not logged in, redirect to login page Header("Location: login.php"); } $con = mysql_connect('localhost','root',''); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("login", $con); $user_name = $_POST['user_name']; $refid = $_POST['refid']; $query = "SELECT * from reference,users WHERE reference.username=users.user_name AND reference.refid='$refid' AND "; $result = mysql_query($query) or trigger_error('MySQL encountered a problem<br />Error: ' . mysql_error() . '<br />Query: ' . $query); while($row = mysql_fetch_array($result)) { echo $row['refid']; echo $row['origin']; echo $row['dest']; echo $row['date']; echo $row['exdate']; echo $row['username']; } echo "<p><a href=\"logout.php\">Click here to logout!</a></p>"; ?> <html> <form method="post" action="final.php"> Ref Id:<input type="text" name="refid"> <input type="submit" value="submit" name="submit"> </html> This could be PHP or MySql so putting it in PHP forum for now... I have code below (last code listed) which processes a dynamically created Form which could have anywhere from 0 to 6 fields. So I clean all fields whether they were posted or not and then I update the mySQL table. The problem with this code below is that if, say, $cextra was not posted (i.e. it wasnt on the dynamically created form), then this code would enter a blank into the table for $cextra (i.e. if there was already a value in the table for $cextra, it gets overwritten, which is bad). What is the best way to handle this? I'm thinking i have to break my SQL query into a bunch of if/else statements like this... Code: [Select] $sql = "UPDATE cluesanswers SET "; if (isset($_POST['ctext'])){ echo "ctext='$ctext',"; } else { //do nothing } and so on 5 more times.... That seems horribly hackish/inefficient. Is there a better way? Code: [Select] if (isset($_POST['hidden']) && $_POST['hidden'] == "edit") { $cimage=trim(mysql_prep($_POST['cimage'])); $ctext=trim(mysql_prep($_POST['ctext'])); $cextra=trim(mysql_prep($_POST['cextra'])); $atext=trim(mysql_prep($_POST['atext'])); $aextra=trim(mysql_prep($_POST['aextra'])); $aimage=trim(mysql_prep($_POST['aimage'])); //update the answer edits $sql = "UPDATE cluesanswers SET ctext='$ctext', cextra='$cextra', cimage='$cimage', atext='$atext', aextra='$aextra', aimage='$aimage'"; $result = mysql_query($sql, $connection); if (!$result) { die("Database query failed: " . mysql_error()); } else { } Say there is a complex opt in process where people start to enter their data but certain questions stop them where they close out of the page. They already entered their data and I feel there is a way to grab it and post it to mysql even though they do not click submit.
How would this be done?
A super simple example (proof of concept) or a link to a tutorial would be very useful.
