How to add callback_ function settings using an array

Hi

I have problem setting rules using an array (Link). I add callbacks (Link) and unfortunately  I receive an error like this "unable to access an error message corresponding you your field name Username. (blacklist)

Simple code for my library validation

PHP Code:

class Validation_lib{
 public function __construct(){
   $this->CI =& get_instance();
 }
 public function getRegister(){
  $getRegisterDetail = array(
            'username'      => $this->CI->input->post('username'),
            'email'         => $this->CI->input->post('user_email'),
            'pswd'          => $this->CI->hash_lib->auth_hash_pswd($this->CI->input->post('user_pswd')),             
            'reg_datetime'  => date('Y-m-d H:i:s'),
        );
  $getRegisterValidation = array(
            array(
                'field'  => 'username',
                'label'  => 'Username',
                'rules'  => 'trim|required|is_unique[user.username]|callback_blacklist',
                'errors' => array(
                        'is_unique' => 'Username <b>'.$getRegisterDetail['username'].'</b> already exists.', 
                    )
            ),
            array(
                'field'  => 'user_email',
                'label'  => 'E-mail',
                'rules'  => 'trim|required|valid_email|is_unique[user.email]', 
                'errors' => array(
                        'is_unique' => 'Email <b>'.$getRegisterDetail['email'].'</b> already exists.', 
                    )
            ),
            array(
                'field'  => 'user_pswd',
                'label'  => 'Password',
                'rules'  => 'trim|required',
            )
        );
        $getRegisterStatus = array(
            'reg_validation'    => $getRegisterValidation , 
            'reg_detail'        => $getRegisterDetail,
        );
        return $getRegisterStatus;
 }
 public function callback_blacklist($str)
    {
        
        if ($username == 'admin') {
            $this->CI->form_validation->set_message('blacklist', 'The field can not be the word "test"');
            return FALSE;
        } else {
            return TRUE;
        }
        
    }
} 


 
How to fix it? Callbacks is available in array?

Thanks!

This is me. JK not me.

public function callback_blacklist($str) 


to:

PHP Code:

public function callback_blacklist($username) 


Change

PHP Code:

public function callback_blacklist($str) 


to:

PHP Code:

public function callback_blacklist($username)

Did you set the validation rules with:

PHP Code:

$this->CI->form_validation->set_rules($getRegisterValidation); 


?

Your function should be called blacklist() not callback_blacklist().

Your function should be called blacklist() not callback_blacklist().

Hi, sorry late reply. Yes blacklist() not callback_blacklist(), I already tried it and didn't work. I wonder if callback_ function is not work in settings using an array...

Did you set the validation rules with:

PHP Code:

$this->CI->form_validation->set_rules($getRegisterValidation); 


?

yes. Inside my controller.

Example code:

PHP Code:

public function register(){
   ....
   //LOAD LIBRARY
   $registerValidation = $this->validation_lib->getRegister()['reg_validation'];
   $this->form_validation->set_rules($registerValidation);
   ....
}

@falcon812311,

CI callback reference: https://codeigniter.com/user_guide/libra...on-methods

While it may not matter...what version of CI are running?

In your validation array "callback_" should be the prefix to your validation function blacklist().

The actual function should be called blacklist().

Is this how your code is currently?
