what does the action part mean in the form?

[rhender]

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. ??

hi,
it means that the the page itself calls from the server, and without anything in action attribute means the same meaning that the page itself calls and the script returns the output on the same page.

Oh ok... thanks rupali.

So just to be sure I'm understanding you correctly... They mean the same thing? Empty or with the PHP SELF stuff...?

my pleasure rhender

yes, both the meanings are same
