would the javascript OnClick= function work?

thats all I can think of at the moment, I don't know of a simple way of doing this with php.

like this (I think)
CODE
<a href="http://www.blah.com" OnClick="<?php function() ?>">tada!</a>

Cause you can't in PHP. It's a server parsed language, not client side. You can't make PHP execute once it's been loaded cause it's no longer PHP, it's all HTML. Think courtney, think.

<---HTML--->
<a href='thispage.php?op=functiona'>

<---PHP--->

<?
function functiona() {
echo "functiona";
}

function functionb() {
echo "functionb";
}

switch($op) {

   case "functiona":
       functiona();
       break;

   case "functionb":
       functionb();
       break;

   default:
       break;
}
?>

edit: erp, just realised matthews posted pretty much the same thing. my bad, guess thats what i get for not reading. wink2.gif


CODE
<a href="index.php?a=2">


CODE
<?php if (a==1) { function() } elseif (a==2) { function2() } ?>


that should take care of what your trying to do (umm, i think)

and yes i know its not proper code. so sue me. tongue.gif

This code will call a funtion based on what you pass in as ?input but it is very insecure and should never be used on a website:
CODE

<?php
function sam(){
  echo "my name is sam";
}
$_GET['input']();
?>

if you pass sam as the value for input (?input=sam) it will run the sam function. wink2.gif
