Hi I have a form in which there is a table, each line of the table displays the detail of a part. the last column of the table has a submit button labeled 'edit'.

The form calls a php script. How can I tell which of the edit buttons was clicked? They all have an identical value unfortunately (since they all display the same text).

Thanks in advance

1. have a unique id per button.
2. in each buttons onlcick event pass the id to a hidden field.
3. read the hidden field in PHP.

Ok, thanks. Only thing I'm not sure about is how to pass the id to the hidden field... how do I go about doing this?

I have a hidden field called 'editme'
Code: 
<input type="hidden" name = "editme" value="0">

and the code for the submit button generation is:

Code: 
<input type="submit" value="Edit" onClick='document.forms["editform"].elements["editme"].value='ZCYC100.008'>
the value is unique for each button (generated by the script). But when I pick up the value of 'editme' it is always zero.

>>'document.forms["editform"].elements["editme"].value='ZCYC100.008'

u are using ' inside '

use this:
'document.forms["editform"].elements["editme"].value="ZCYC100.008"'

Ah, simple as that.
Thanks a million. I guessed it was something simple but for the life of me just couldn't work out what.

Here is a another method to do what you requested without resorting to Javascript.

This example should get you going.
Code: 
<?
if (isset($_POST['submit'])) {
	foreach ($_POST['submit'] as $k=>$dmy)
		switch ($k) {
			case 'one':
			case 'two':
				echo 'Button <span style="font-weight:bold;color:red">'.$k.'</span>';
				break;
			case 'three':
				echo 'Button <span style="font-weight:bold;color:white;background-color:red">' . $k . '</span>';
				break;
		}
	echo ' was pushed';
}			
?>
