tip: php and defining functions

[gabrielcrowe]

in actinic, you can use php to do complex things, we know this, but what happens when you want to define a function?

first of all, you can do it in the actinic_main.php file, but, what if thats not appropriate?

well, if you define a function within a template, actinic accepts it, but then, if you look at the page again, it suddenly decides to throw a wobbler. You cannot define the same function twice in the same session.

PHP does not allow you to 'unset' a function, but luckily, I found a quick workaround:

if (!function_exists('myFunc')) {
    function myFunc($variable) {
    //function here
    }
} 

Voila. The function is created on the first pass, then next time its parsed, actinic skips over the creation.

Hope this helps someone.

Thanks Gabe, very good tip!

if (!function_exists('myFunc')) {
  // just remember that any changes you make inside this block will
  // not take effect until you restart actinic :)
}
