form_validation - get field value in callback function

Hi,

[quote author="Colin Williams" date="1261166172"]All form_validation prepping is applied directly to the $_POST array.[/quote]

Thank's for this hint. That helps me.

[quote author="Colin Williams" date="1261166172"]But, given the order in which your fields are defined, your username callback will fire before the validation class has a chance to process the first_name field.[/quote]

Well .... okay. I will play a little bit with the order of the rules. I think I can solve my problem this way.

Tank's for your help!
