Form Validation - Modify Second Parameter

[eluser]psychoder[/eluser]
never done that before... but got it working by using a protected or private variable( in a class),
assign the value to be used in a callback function to that variable and access or use that in your
callback function

Code:

class ....{

   protected $data_for_callback;

   ....

   method calling_form_validation()
   {
       $this->data_for_callback = value_to_be_used_in_call_back;
   }

   callback_method($param)
   {
       //access or use it now
       $this->data_for_callback ....
   }
}
