Validation

Hey Schnoodles, I don't know if I properly understand what you're asking, but this is what I would do:

- to create callback methods in your controller to check uniqueness and password validity:

Code:

function _is_unique($data){
    // set the validator error message here
     $this->validation->set_message('_is_unique', 'The %1$s is already taken.');

    // do your normal queries to the database here to check if something is unique.
    // If not return false. The validator doesn't care what happens here, it just cares
    // to see if the callback returns false, in which case the previously set error
    // message is displayed.

}

function _valid_password($username){
    // set the validator error message here
     $this->validation->set_message('_valid_password', 'The Password is incorrect.');
    
    // do your normal authentication routines here
}

Alternatively, you can look for the language file /language/english/validation_lang.php and add your error messages there. Following the format that you find in the file, just put the name of the callback method and the custom error message.


- Now to authenticate and use the validation mechanism you would do this upon submit:

Code:

$rules['username'] = 'callback__valid_password';
$fields['username'] = 'User name';
$fields['password'] = 'Password';
$this->validation->set_rules($rules);
$this->validation->set_fields($fields);
$valid  = $this->validation->run();
