?>

these are the two pages i need to place in single page.

why does he want it all on one page? seems odd

ok it seems i get a hint of what you want to do you try to post a form or something and your team leader wants the code to be in a single script. then all you got to do is just copy out the php script in the second page unto the topmost part of your first script before any html content and try and do an if post check on it. then change your form action on the first page to the first page name.i hope this helps

You only validate some of the things in the first file, so as your lead suggested integerate the both as a single file, and check the submit to make the action that is trigger on the same page.

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
