PHP executes server-side; Javascript executes client-side. The PHP has been executed and is all done before the Javascript even makes it to the browser, where *it* gets executed. And the PHP parser has no concept of Javascript functions; it's all just text. So PHP can't know whether a given Javascript function is going to run or not. You'll need to take that into account and perhaps have PHP generate the appropriate Javascript code to send to the browser. But remember to keep in mind that they don't share execution times. For what you're trying to do (client-side form validation?), why not use pure Javascript for the validation and then submit it to a PHP script for processing on the server? Better yet (unless it's for an Intranet or otherwise captive audience where you *know* they have Javascript turned on) do it all in PHP. -- +----------------------------------------------------------------+ |Torben Wilson <torben@php.net> Netmill iTech| |http://www.coastnet.com/~torben http://www.netmill.fi| |Ph: 1 250 383-9735 torben@netmill.fi| +----------------------------------------------------------------+
