how to make ignore variable custom about uniquewith-validator HOT 3 CLOSED

'first_name' => 'required|unique_with:users,last_name,2 = custom_field',

from uniquewith-validator.

Let me explain:
The update url's can be:
/user_profile_data/1/edit
/user_profile_data/2/edit
/user_profile_data/3/edit

on this moment when i fire for example the first url, it dont pass. Because i dont specify the update id. When i do this, it works:

public static $rules = array(
    'user_id' => 'unique_with:user_profile_data, type, 1 = id'
);

Now i want to make 1 variable depending on the id in the url or post value. Because when i open 2/edit it doesnt work because 1 is set. Can you help me?

Solved with this function in my model:

public function changeRulesBeforeUpdate($id) {

    static::$rules = array(
        'user_id' => 'unique_with:user_profile_data, type, '.$id.' = id'
    );

}
