Problem with functions

[markster]

How can I use a button to trigger a PHP function? I thought it might be a code like:

<input type="button" value="Click Me!!!" onClick="I DUNNO">

Please help!!!

You can't. (unless you use AJAX, which I would not recommend before you understand how PHP works)

PHP only runs server-side. It is used to print text to the browser.

HTML/Javascript runs on the client (browser). By the time the HTML is drawn, PHP is done running.

You would have to request a new PHP page (submit an html form to a PHP page) to access PHP functions.

Awww, thats not good!

Second thoughts, is there anyway to use PHP to trigger a javascript function?

PHP Code:

<?php 
echo "<script language=\"Javascript\">my_function();</script>";
?>

Else I dont see how... remember php is server-side, javascript is client side, so unless you tie them together through Ajax, theres not much interaction between them.

surely there is a way to do what you want to do with either javascript or php. what exactly are you trying to do with the button click?

dont worry, ive managed to recreate the javascript in PHP, so its all in php now!
