How can I execute a PHP function in a form action?

Question

I am trying to run a function from a PHP script in the form action.

My code:

Answer 1

Is it really a function call on the action attribute? or it should be on the onSUbmit attribute, because by convention action attribute needs a page/URL.

I think you should use AJAX with that,

There are plenty PHP AJAX Frameworks to choose from

http://www.xajax-project.org/en/docs-tutorials/learn-xajax-in-10-minutes/

ETC.

Or the classic way

I hope these links help
