how to assign the onSubmit value of a form to a PHP function ?

Can't. PHP is a server-side scripting language. The client doesn't know anything about it.

The closest you're going to get is if you just submit theform.

i am using such as this code to get my php function( myFunction() ) by a javascript function( test() ) . but when call test() it doesn't work becuase the php function run at loading of page and after it it doesn't work.

<?php
function myFunction(){
return true;
}
echo "<script language=\"Javascript\"> function test(){ return \"".myFunction()."\"; } </script>";
?>

Well, no. PHP runs on the server - after the stuff gets sent to the client PHP has nothing more to do with it - PHP functions won't run after the page has loaded, because there aren't any PHP functions in the page (use the browser to view the source if you don't believe me).

Why would you want to run a PHP function as your onSubmit handler?

Your a total newbie to this stuff as i can tell

I suggest looking at some PHP Tutorials. Oxyscripts.com Spoono.com are good to start off.

I also suggest about thinking of getting a book.
Now i never have got one. But its a little harder and slower to learn PHP by yourself espeacially if you get into trouble and not sure of how to fix it.
