I have this in the action attribute in my form element on my personal site.
<form action="<?php $_SERVER['PHP_SELF'] ?>" method="POST">
It works fine, but I'm just wondering what it means in layman's terms.
The reason I ask, is because I am helping a friend with his forms, and the action attribute is empty within the quotations.
So I'm guessing it does nothing, if there is nothing for the action. ??
