I am trying to do a "normal" include in a template, but since I do not want the include to show on EVERY page, I am trying to make it so that the include only includes the specified page at a specified url.

Here is what I have tried

<?php include("submitart.php"); { 
     if (strpos( $url )) { $url = '/gallery'; } 
} ?>

But alas, no luck. Any suggestions?
