PHP - Ajax And Php Problem

I have an AJAX request but my problem is that is always returns a status code of 0.  Below I have my JavaScript function.  They send a request to a page called inc_submit.php which just echo's "hi" (as I'm just try to test it). 

Code: [Select]
function submitForm(website_name, website_caption, website_contact, website_email, website_link) {
var url4 = "includes/inc_submit.php?website_name=" + escape(website_name) + "&website_caption=" + escape(website_caption) + "&website_contact=" + escape(website_contact) + "&website_email=" + escape(website_email) + "&website_link=" + escape(website_link);
alert (url4);
request4.open("GET", url4, true);
request4.onreadystatechange = confirmSubmit;
request4.send(null);
}

function confirmSubmit() {
if (request4.readyState == 4) {
if (request4.status == 200) {
var response4 = request4.responseText;
document.getElementById("submit_status").innerHTML = response4;
} else {
alert("Error: status code is " + request4.status);
}
}
}

Hi,

Using arabic characters,

I have a project, in the admin panel, where i am trying to change the value in the text box(ajax) on onblur js function.
Firefox simply working great but i am getting square brackets in the text box in the browser ie.

I simply guessing the value from the text box is not in the form of utf-8 encoding, i am calling the external javascript file, this is the code am using..

Code: [Select]
// JavaScript Document



var xmlhttp;
//function namechange(name_fieldvalue)


function namechange(name_fieldvalue,name_fieldname,id_val,id_fieldname,table_name)
{
/*
alert(name_fieldvalue);

alert(name_fieldname);
alert(id_val);
alert(id_fieldname);
alert(table_name);
*/

if (name_fieldvalue.length==0)
  {
  document.getElementById("txtHint").innerHTML="";
  return;
  }
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null)
  {
  alert ("Your browser does not support XMLHTTP!");
  return;
  }
var url="ajax_namechange.php";
url=url+"?name_fieldvalue="+name_fieldvalue;
url=url+"&name_fieldname="+name_fieldname;
url=url+"&id_val="+id_val;
url=url+"&id_fieldname="+id_fieldname;
url=url+"&table_name="+table_name;
xmlhttp.onreadystatechange=stateChanged;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}



function stateChanged()
{
if (xmlhttp.readyState==4)
  {
  document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
  }
}



function GetXmlHttpObject()
{
if (window.XMLHttpRequest)
  {
  // code for IE7+, Firefox, Chrome, Opera, Safari
  return new XMLHttpRequest();
  }
if (window.ActiveXObject)
  {
  // code for IE6, IE5
  return new ActiveXObject("Microsoft.XMLHTTP");
  }
return null;
}





Anyone has the idea on this, please help me.

Thanks,

Hello,

I am trying to implement some code I found and downloaded he
http://www.roscripts.com/Ajax_autosuggest_autocomplete_from_database-154.html

When I try and run this I get no search results back when searching? I have entered data in the database and all connections seem good. Several people in the comments say they have problems, but no solution.

Any one that can find the fault here?

- THANKS

Hi...

I have a problemand I tried to resolved it but still I failed..

I need to add a code in a php file where I'm not the one who code, now I need to add code on that file, and the problem is the one who the owner of code is not here.

I need to add code :

Code: [Select]
$sub_lotcode = substr($lotCode, 9, 4);
   
    $sql = "SELECT k.PCODE, k.kanban, p.Compounds, p.Max_Lot
            FROM kanban_checker k, param_settings p
        WHERE k.kanban = p.Max_Lot AND k.PCODE = '$sub_lotcode' AND p.Compounds = '$sub_lotcode'";
        $result = mysql_query($sql, $con);
         $total = mysql_num_rows($result);
        if ($total <= 0) {
            notify that PCODE reach the maximum        }
        else{
            echo "continue";
        }

here is the code where I need to add this condition:

Code: [Select]
<?php
error_reporting(0);
$con = mysql_connect('localhost', 'root','');

if (!$con) {
    echo 'failed';
    die();

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>

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

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 

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?

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

This topic has been moved to Ajax Help.

im trying to get this ajax function working but for some reason it runs the error function...I've corresponded with the manual and I can't see a fault...any advise would be great...thanks

$(document).ready(function() 
{
	$.ajax(
	{
		url: "items.php",
		dataType: "json",
		data: '<?php echo $data; ?>',
		timeout: '2000',
		cache: false,

		error: function(data) 
		{ 
                  alert('error');
	    },

		success: function(data)
		{ 
			$.each(data, function() 
			{
				$("#table").append('<div class="row"><span class="cell">'+ data.title +'</span><span class="cell"></span><span class="cell"></span></div>');
			});
		}
	 });
});

Pardon my noobness, but I'm learning to wrap AJAX into my work and use it to get XML instead of "static" PHP that generates the HTML.  The login/security portion has my head spinning, but it's probably not as difficult as I think and I'm probably just confusing myself. 

In the past, for each PHP page in my site, I would perform a quick salted login check based on the username/password stored in the $_SESSION variables.  Perhaps it was a bit overboard to check on each page, but, well, I did it.

With AJAX, I *NEED* to ensure that the php resulting from an AJAX POST request won't run if the user isn't authenticated, and I need to ensure that they didn't just somehow force a $_SESSION variable to reflect an authenticated session.  I also need to ensure that someone can't just load up the PHP page on it's own, somehow send a POST to it and run it without being authenticated. 

I suppose that beyond the larger picture of "How do I ensure that the user is authenticated, the POST request is authentic, and nobody has forced a change in the $_SESSION stored on the server, I have a few specific questions. 

I know that in part I'm confused about the whole cookie/SESSION process.  In my old PHP site, the SESSION number was stored on the cookie on the user's machine.  If the info is sent via AJAX, does the PHP get the SESSION info from the cookie or does it have to be explicitly sent?  With potentially several users sending AJAX requests at the same time, how will my PHP know which SESSION to use for each request?

Is is secure enough to set an "Autheticated" flag in $_SESSION once the user is authenticated the first time?   Is it really just as simple as sending a username/salted password hash as AJAX/POST and setting an authenticated flag in the SESSION to ensure that the rest of the AJAX application runs without allowing someone to back-door the PHP?
