Referenced?

[TutorMe]

Is there a way to check if a page was called from another page?  Like if I have a link on a page called "index.php" that links to "register.php," can I put a code at the top of "register.php" that checks if it was opened through "index.php?"

 

Sorry if that's confusing.

$_SERVER['HTTP_REFERER'] will contain the URL of the page that linked to the current one. If you use basename on it, you can get just the file.

echo basename($_SERVER['HTTP_REFERER']);
