Ajax.InPlaceEditor php code need help

[acctman]

everytime i try to upload it fails, i've been trying to find an example of how to update but all the example either don't use PHP or just show a generic text changing without really saving anything.

 

webpage:

<?
$mp3user = mysql_query("SELECT `mp3_id`,`mp3_userid`,`mp3_title` FROM `rate_mp3s` WHERE `mp3_userid` = '".$en['m_id']."'");

echo "<ul style=\"margin-left: 210px;\">\n";
$counter = 1;
while($en = mysql_fetch_array($mp3user)) {
echo "<li>MP3 " .$counter. " : <span id=\"mp3title-".$counter."\">".$en['mp3_title']. "</span> | <a href=\"/modules/rating/process_mp3.php?user=" .$en['mp3_userid']. "&mp3=" .$en['mp3_id']. "\">Delete</a></li>\n";
$counter++;
}
echo "</ul>\n";
?>

<script type="text/javascript">
new Ajax.InPlaceEditor('mp3title-1', '/modules/rating/process_mp3.php');
new Ajax.InPlaceEditor('mp3title-2', '/modules/rating/process_mp3.php?user=<%m_id%>&id=<%mp3_id%>');
new Ajax.InPlaceEditor('mp3title-3', '/modules/rating/process_mp3.php?user=<%m_id%>&id=<%mp3_id%>');
</script>

 

process_mp3.php

 

<?php
session_start();

$value = $_POST['value'];
//$id = (int)$_GET['mp3'];

$mp3_update = mysql_query("UPDATE `rate_mp3s` SET mp3_title='$value' WHERE mp3_id='".$_GET['mp3']."'");
echo $value;
?>
