So Simple but if you don't know it's hard.

No problem. :)

Corey, you there again?

I have another little issue.

I am passing this using the address bar.

tp=template1.swf

I need to strip that down and include a form based on the number passed.

include_once("includes/form#.php");

Any help much appreciated.

Thanks

I just tried with this but its wrong somewhere.

<?php $firsttrim = trim($_GET['tempate'], "template");?><br /><?php echo trim($firstrim, ".swf");?>


Worked it out now.

<?php $firsttrim = trim($_GET['tempate'], "template");?><br /><?php echo trim($firsttrim, ".swf");?>
