defining functions inside datamanagers

[merk]

I have tried to define a new function inside the attachment datamanager

PHP Code:

if(!function_exists('verify_fieldname'))
{
  function verify_fieldname(&$data)
  {
    /*<do stuff>*/
  }
}
 
$this->validfields['fieldname'] = array(TYPE_HERE, REQ_NO, VF_METHOD); 


A fatal error occurs stating the method cannot be found.

Am i doing something wrong? this is how it is described in the vBulletin manual.

Can you give the exact location where this is stated in the manual?
As it seems to be wrong

You cannot create methods for objects at runtime; this is a PHP limitation.

What you can do is using a lamda function that calls your custom verification function:

PHP Code:

if (!function_exists('verify_fieldname'))
{
    function verify_fieldname(&$dm, &$data)
    {
        /*<do stuff>*/
    }
}


$this->validfields['fieldname'] = array(TYPE_HERE, REQ_NO, 'return verify_fieldname($data, $dm);');

Sorry, my mistake, the code in the manual shows what you've pasted, i was trying to use VF_METHOD where it should have been just a string.

Got it working now, thanks
