I have the following which is causing me grief:

Code:
            
<?php
if (CountModules('m1') >= 1 OR CountModules('m3') >= 1 ) { 
etc
}
?>


I have created a plugin to return the CountModules value, eg:

{CountModules position='m1'}

But how do I include the results in an if statement?

Create a modifier rather than a function plugin.

Thanks. I've done this:

Code:

function smarty_modifier_mosCountModules ($position) {
   return mosCountModules($position);
}


called thus:

Code:

{if ("m1"|mosCountModules gte 1) OR ("m3"|mosCountModules gte 1 ) }
etc...

It seems that mosCountModules is already defined as a normal PHP function. As long as you don't use Smarty's security features, it should be available automatically both as a modifier (without writing a plugin wrapper) and as a valid function that can be used in if statements.
