RE: php ajax

Eric, could I suggest using Prototype (http://www.prototypejs.org/) instead
of your own code.

It's very easy to use, like this :-

<script src="prototype.js"></script>
<script>
function update_content() {
	new Ajax.Updater('dynamic', 'ajaxtest.php',
			{ method: 'post', parameters: { task: 'details' } });

}
</script>

The full PHP script would look like this :-

<?php
if (@$_POST['task'] == "details") {
	echo "This is some text returned from the PHP engine via AJAX";
	exit;
}

?>

<html>

<head>
<title>Ajax Test</title>
<script src="prototype.js"></script>

<script>

function update_content() {
	new Ajax.Updater('dynamic', 'ajaxtest.php', { method: 'post',
parameters: { task: 'details' } }); 
}
</script>
</head>

<body>

<table border="1" width="100%">
  <tr>
    <td width="33%" onclick="update_content()"><a href="#">Update
content</a></td>
    <td width="33%">&nbsp;</td>
    <td width="34%">&nbsp;</td>
  </tr>
  <tr>
    <td width="33%">&nbsp;</td>
    <td width="33%"><div id="dynamic">I am going to put some content
here</div></td>
    <td width="34%">&nbsp;</td>
  </tr>
  <tr>
    <td width="33%">&nbsp;</td>
    <td width="33%">&nbsp;</td>
    <td width="34%">&nbsp;</td>
  </tr>
</table>

</body>

</html>

Robert.

Hi Eric,

  You have created Javascript(Ajax) functions but you have not made call for
that code I guess.
  You should have called the functions from your html part like
onload(load******)
  or onclick(load******)

  Thanks
