It's fairly simple: at the top of your script, have a block of code similar
to the following, and have the link point to
--
$_SERVER['PHP_SELF']."?rm_id=".$id_to_be_deleted
--
I'll leave out all but the essential elements.
<code>
<?php
if (isset($_GET['rm_id']))
{
$query = "REMOVE FROM whatever WHERE id = ".$_GET['rm_id']." LIMIT 1";
mysql_query($query);
}
?>
</code>

In linux under Netscape 7 and Opera 7.2 it reloaded the page :/ That
said looking at the URL when the mouse is over the link:
http://www.blocket.se/new?caller=ogl_s&l=0&rm_id=2595475&city=0
The rm_id is being set as a GET variable with an appropriate ID to
remove the entry. So when the page reloads it first deletes the entry.
This is standard functionality in many websites.
Cheers,
Rob.
