KO 2.3.4 - Accessing validation array from callbacks in models
- by kenny99
Hi,
Apologies if this is an oversight or sheer stupidity on my part but I can't quite figure out how to access the validation array from a callback in a model (using ORM and KO 2.3.4). I want to be able to add specific error messages to the validation array if a callback returns false.
e.g
This register method:
public function register(array & $array, $save = FALSE)
{
// Initialise the validation library and setup some rules
$array = Validation::factory($array)
->pre_filter('trim')
->add_rules('email', 'required', 'valid::email', array($this, 'email_available'))
->add_rules('confirm_email', 'matches[email]')
->add_rules('password', 'required', 'length[5,42]')
->add_rules('confirm_password', 'matches[password]');
return ORM::validate($array, $save);
}
Callback:
public function email_available($value)
{
return ! (bool) $this->db
->where('email', $value)
->count_records($this->table_name);
}
I can obviously access the current model from the callback, but I was wondering what the best way to add custom error from the callback would be?
