Think back to the order that this stuff is going to be
processed... PHP is server side, and the code is going to be
executed on the server before it even goes back to the
browser. Thus your db record will be deleted either way.
The way I do this is to create a JavaScript function on the
first page (the one with the buttons/links to delete stuff)
that looks something like this:
<script language="javascript">
function dbDelete(strDescription, itemId) {
if (confirm('Warning:\n\nYou are about to delete ' .
strDescription . '.\n\nDo you wish to proceed?'))
location.href='path/to/delete/file.php?id=' .
itemId;
}
</script>
And let file.php perform the deletion and return to where
ever is an appropriate return location.

It doesn't because it's processed server-side and not
client-side...
