Similar Tutorialshey...im trying to display messages stored in a database on a page using ajax. a user should choose from a drop down list the title of the message and then on selection that message should appear just below. but i cant seem to do it and i dont know why there is no errors in what ive got so far. here is the code for the drop down box where the user would select the title. Code: [Select] <form> <select name="users" onchange="showMessage(this.value)"> <option value="">Select a message:</option> <?php while($rows = mysql_fetch_array($results)) {?> <option value="1"><?php echo $rows['heading']; ?></option> <?php } ?> </select> </form> <br /> <div id="txtHint"><b>Message info will be listed here.</b></div> the drop down is successfully populated with the correct titles. here is the javascript in the HEAD of the same page: Code: [Select] <script type="text/javascript"> function showMessage(str) { if (str=="") { document.getElementById("txtHint").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("txtHint").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","showmessage.php?id="+str,true); xmlhttp.send(); } </script> and here is the php file which is used to display the message upon selection. <?php $id=$_GET["id"]; $cust = new customer; $sql="SELECT * FROM messages WHERE m_id = '".$id."'"; $result = mysql_query($sql); ?> <table border='1' cellspacing="4"> <?php while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<th>Heading</th>"; echo "<th>Message</th>"; echo "</tr>"; echo "<tr>"; echo "<td>" . $row['heading'] . "</td>"; echo "<td>" . $row['message'] . "</td>"; echo "</tr>"; } ?> </table> could someone please take a look at this and see whats wrong? ive spent so long on it. if you could tell me how to correct it it would be great I have created a registration page to access my website. After the user registrate himself should appear an alert saying that the registration was OK and a redirect to main.php page... however for some reason if I create an insert statement the alert and the redirect don't appear... If I remove the insert the alert and the redirect works... why? This is part of the code of my 3 files: registration.php (ajax call) $('#submit').click(function() {var username2 = $('#uname2').val(); var password2 = $('#psw2').val(); $.ajax({ url: 'ajax/response.php', type: 'GET', data: {username2 : username2, password2: password2}, success: function(data) { if(data === 'correct') { alert("Username and Password have been created!"); //don' work with the insert location.replace("main.php"); //don' work with the insert } else { alert("Username or password are not correct... please register yourself!"); } } }); }); response.php (answer to ajax call) if(isset($_GET['username2']) && isset($_GET['password2'])) {$username2 = $_GET['username2']; $password2 = $_GET['password2']; if (checkUser($pdo, $username2) === true) { echo 'duplicate'; } else { insertUserPwd($pdo, $username2, $password2); //including this line the redirect and the alert doesn't work... the insert is OK echo 'correct'; } } data_access.php (the function works but doesn't permit alert and redirect to appear) function insertUserPwd(PDO $pdo, $usr, $pwd){ $data = [ 'id' => '', 'user' => $usr, 'password' => $pwd ]; $sql = "INSERT INTO users (id, user, password) VALUES (:id, :user, :password)"; $stmt= $pdo->prepare($sql); $stmt->execute($data); } Can someone help me to fix the code? 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. Hello, 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 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; } } } Hi.., I use below method to export data to excel. header('Content-type: application/ms-excel'); header('Content-Disposition: attachment; filename=abc.xls'); if I run the script from the server. (http://localhost/export.php) it is work. (pop-up window if i want save or open the file) but if i run the script from the client (http://192.168.1.5/export.php) it is not work. (nothing happen) any idea how to solve this? This one requires lots of up front information: I have a page, for this example that I will call page.php. It takes get parameters, and for this example I'll call the parameter "step". So I have a URL like this: page.php?step=1 This page has a form with an action of page.php?step=1. The code on the page validates the posting information. If the information is bad, it returns the user to page.php?step=1; if it is good, it takes the user to page.php?step=2 via header( "location:page.php?step=2" ). So redirection is done by relative path, not full URLs. This all works as expected. Now what I've done is set .htaccess to be HTTPS for this page, via this code: # Turn SSL on for payments RewriteCond %{HTTPS} off RewriteCond %{SCRIPT_FILENAME} \/page\.php [NC] RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L] This works (initially). However, once you try to post the form, it just redirects back to the step=1 version of the page. I really don't know how or why that would be. I'm not sure how else I can explain this or what other information you may have. But it's frustrating to not get a page working in HTTPS that works in HTTP. Very odd. Any suggestions? (I don't even really know the best location to figure out when/why it's redirecting back to the original page.) require_once 'includes/upload.class.php'; $upload = new uploads(); $details = $upload->getFileInformation($id); <?php echo $details['upload_desc']; ?> then here the class. require_once 'db.class.php'; class uploads extends database { private $uploadData; function uploadFile() { public function getFileInformation($id) { $this->uploadData = $this->readData("uploadfiles", "upload_id", $id); return $this->uploadData; } But it wont work! Some of you may have seen one of my many posts about email issues. Some users don't get them, and I have determined it is probably because we are marked as spam.
We are a service that grades sales team members on their phone skills. Listening to pre-recorded calls, grading and uploading them to our site, and then another part of our business looks them over and sometimes leaves a message that then get's forwarded to this persons work email.
I have determined there is ways to get marked as spam as default by not having an opt out link. This is not an option, these sales members employer has opted in, and the emails are going to work related accounts hosted at that employer. Also, if one of these staff members is not so bright, or disgruntled they may mark us as spam anyways. The bottom line is that we have very little control over whether we are or are not marked as spam.
So we want to start looking into sending text messages and this is where I start to question how good of an idea this is.
First off, if it was me, and the messages where being sent to a device that my employer did not provide, I would in no way want work related text messages coming to me. Unless there is a vested interest in getting them. IE, I'm the boss at this place and am always on the clock. What if you are on the bottom? It's just a job for you.
What if it is a pre-paid device, text messages cost money. What then? What if they don't even have, or want a cell phone?
The short of it is this. If I'm at a job that is just another job, and this employer tells me that I have to get these messages. I'm going to look for another job. I see the organizations having continuous issues and complaints from their employees. Thus us as a business having issues keeping clients.
What am I getting into here? What are your opinions on this matter? What are your recommendations as to alerting users of something on our site that we can rest assured are being received 100% of the time?
Thanks!

Hi guys, I am after some simple code/tutorial that shows how to make an AJAX/jQuery function to fetch data from a PHP MySQL Database on a timed interval. So far I have not been able to find a simple example of this so if anyone can help out that would be very much appreciated. Cheers in advance. How should I structure XMLHTTPRequests? Should I create a controller called Ajax and post/get all ajax calls through the methods of that controller? What have other people done in the past? What worked best for you? Just thought I would ask as I see that the AJAX help board is something of a ghost town (much like the MS SQL board). Since my post there doas also have some php in it, and I am in no way certain my problem is not in the php could anyone that knows a bit of both please have a look at it he http://www.phpfreaks.com/forums/index.php?topic=343419.0 cheers, just hope this circumvents the double posting rule i have a select box and need to change the data with the selection.it is working correctly , my problem is that in the data i have a paging .when we going to next page no data showing . ie select box will not have any value. how to solve this problem. thanks in advance i need help trying to get this delete feature to work its not deleting from the database (by the way i took out my database names and passwords at the top of the file) is it possible someone could help me, ive been working on this for like a week and cant figure out the problem. thanks! you can email me at spr_spng@yahoo.com picture 2.png is showing what it looks like Code: [Select] <?php $host="localhost"; // Host name $username="username"; // Mysql username $password="password"; // Mysql password $db_name="database_name"; // Database name $tbl_name="table_name"; // Table name // Connect to server and select databse. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); $sql="SELECT * FROM $tbl_name"; $result=mysql_query($sql); $count=mysql_num_rows($result); ?> <style> /*table affects look of the whole table look */ table { margin-left: auto; margin-right: auto; border: 1px solid #330000; border-collapse:collapse; width:70%; border-width: 5px 5px 5px 5px; border-spacing: 1px; border-style: outset outset outset outset; border-color: #330000 #330000 #330000 #330000; border-collapse: separate; background-color: #330000; #800517 f535aa #330000 school color #9A0000 school color2 #991B1E school color3 #CCCC99 school color4 #9A0000 } /*th is table header */ th { text-align: left; height: 2.5em; background-color: #330000; color: #FC0; font-size:1.5em; } /*td is table data or the cells below the header*/ td { text-align: left; height:1.0em; font-size:1.0em; vertical-align:bottom; padding:10px; border-width: 5px 5px 5px 5px; padding: 8px 8px 8px 8px; border-style: outset outset outset outset; border-color: #9A0000 #9A0000 #9A0000 #9A0000; background-color: #CCCC99; -moz-border-radius: 0px 0px 0px 0px; } </style> <table width="400" border="0" cellspacing="1" cellpadding="0"> <tr> <td><form name="form1" method="post" action=""> <table width="400" border="0" cellpadding="3" cellspacing="1" bgcolor="#CCCCCC"> <tr> <td bgcolor="#FFFFFF"> </td> <td colspan="4" bgcolor="#FFFFFF"><strong>Pick Which Rows you want to delete, Then press delete.</strong> </td> </tr> <tr> <td align="center" bgcolor="#FFFFFF"><strong>Id</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Name</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Lastname</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Email</strong></td> <td align="center" bgcolor="#FFFFFF">delete</td></tr> <?php while($rows=mysql_fetch_array($result)){ ?> <tr> <td bgcolor="#FFFFFF"><? echo $rows['id']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['name']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['lastname']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['email']; ?></td> <td align="center" bgcolor="#FFFFFF"><input name="checkbox[]" type="checkbox" id="checkbox[]" value="<? echo $rows['id']; ?>"></td> </tr> <?php } ?> <tr> <td colspan="5" align="center" bgcolor="#FFFFFF"><input name="delete" type="submit" id="delete" value="Delete"></td> </tr> <? // Check if delete button active, start this // edited if($delete){ for($i=0;$i<$count;$i++){ $del_id = $checkbox[$i]; $sql = "DELETE FROM $tbl_name WHERE id='$del_id'"; $result = mysql_query($sql); } // if successful redirect to delete_multiple.php if($result){ echo "<meta http-equiv=\"refresh\" content=\"0;URL=delete_multiple.php\">"; } } mysql_close(); ?> </table> </form> </td> </tr> </table> Hi there, As the question says i tried several things but i can't work it out and my knowledge about php isn't that well. Please help with this, it not going to the .html controller and returing the values need, it captures the email form values, bu then fails with a 406 error.

Greetings all,
Been trying to make a plugin in wordpress and ran into an issue with the way wordpress makes use of ajax in the administration menu. The problem is that I completely don't understand it. I've read all the docs on it and even tried messing with a variety of tutorials on the matter to no avail.
What I am trying to do is a simple task outside of wordpress. The form has two select fields, the first field populates the second selection field. While this works fine on a standard html page, trying to do it in wordpress is another story.
Form.php:
<div id="wrapper">
<h1>Second dropdown selection based </h1>
<form action="" method="post">
<p><label>Main Menu :</label>
<select name="main_menu_id" id="main_menu_id">
<option value="">Select</option>
<?php
// Connect to database.
$connect = mysqli_connect('<!--DB connection info-->");
$q = mysqli_query($connect, "SELECT cfid,cfname FROM categoryfiles ORDER BY cfid");
while($row = mysqli_fetch_array($q)) {
echo '<option value="' . $row['cfname'] . '">' . $row['cfname'] . '</option>';
}
?>
</select>
</p>
<p><label>Sub Menu: </label>
<select name="sub_menu_id" id="sub_menu_id"></select>
</p>
</form>
</div>
The script.js
$(function() {
$("#main_menu_id").bind("change", function() {
$.ajax({
type: "GET",
url: "scripts/get_sub_category.php",
data: "main_menu_id="+$("#main_menu_id").val(),
success: function(html) {
$("#sub_menu_id").html(html);
}
});
});
});
The get_sub_category.php
<?php
// Connect to database.
$connect = mysqli_connect('<!--My connection info-->);
$id = $_GET['main_menu_id'];
$q = mysqli_query($connect, "SELECT sfid, sfname FROM subjectfiles WHERE sfcategory='" . $id . "' ORDER BY sfname");
while($row = mysqli_fetch_array($q)) {
echo '<option value="' . $row['sfname'] . '">' . $row['sfname'] . '</option>';
}
?>
Like I said, it works just fine outside of wordpress so really I just need help getting it to work in wordpress. I just don't understand it. Thanks to anyone that takes the time to look this over.
Best Regards,
Nightasy
Me and one other person have just started developing a forum package, it's the first time that either of us have really used AJAX, but we're both pretty good with PHP. We're trying to work out the whole submitting a registration form using AJAX, we have the page http://www.example.com/account/register When the user visiter goes to this site they're presented with the registration form, as you'd expect. When the form is submitted, AJAX does a POST request thing (Whatever you call it) to the same page, the script on this page checks to see if there's any post data and if there is, it validates it and sends it to the database etc. The problem is, what is there to stop anyone from sending post data to this site and adding random users? The same problem would occur if we were to add functions to delete and change users. Any hackers could send post data and delete users. Are we doing something wrong, or is there something obvious we've missed? Hi there,
I have been following a tutorial online to create simple pagination using ajax. The pagination side of things works perfectly however I want to pass a GET variable through the page that is being loaded by jquery.
Config.php:
$item_per_page = 2;Index.php:
<?php
include("config.php");
$results = mysqli_query($connecDB,"SELECT COUNT(*) FROM jobs");
$get_total_rows = mysqli_fetch_array($results); //total records
//break total records into pages
$pages = ceil($get_total_rows[0]/$item_per_page);
//create pagination
if($pages > 1)
{
$pagination = '';
$pagination .= '<ul class="paginate">';

fetch_data.php:
include("config.php"); //include config file
//sanitize post value
$page_number = filter_var($_POST["page"], FILTER_SANITIZE_NUMBER_INT, FILTER_FLAG_STRIP_HIGH);
//validate page number is really numaric
if(!is_numeric($page_number)){die('Invalid page number!');}
//get current starting point of records
$position = ($page_number * $item_per_page);
//Limit our results within a specified range.
$results = mysqli_query($connecDB, "SELECT * FROM jobs ORDER BY created_at DESC LIMIT $position, $item_per_page");
//output results from database
echo '<ul class="page_result">';
while($row = mysqli_fetch_array($results))
{
echo '<li id="item_'.$row["title"].'">'.$row["title"].'. <span class="page_name">'.$row["location"].'</li>';
}
echo '</ul>';
If I try to print out a $_GET variable in the fetch_data.php file I just get a blank response. The reason I want to do this is so when I integrate it into my actual site I have a search feature that filters through the query.
If anyone could give me some guidance to what needs to be done that would be great.
the tutorial is located he http://www.sanwebe.c...with-jquery-php
Many thanks,
Zack.
