Hi all!

\Config\Validation.php

PHP Code:

public $validateForm = [
        'name'        => 'required|min_length[4]|trim',
]; 


Controller:
$this->validation->run($this->request->getPost(), 'validateForm');

Error:
Call to undefined function CodeIgniter\Validation\mb_strlen()
BASEPATH/Validation/Rules.php at line 259


same error if use max_length

Looks like you are running a PHP version that does not have the mb_strlen() function available

PHP Version 7.0.18-1+deb.sury.org~trusty+1

Are you sure mb_strlen() has been enabled?

You can check by using phpinfo()

yep, it looks like it's not enabled, no info about mb_ in phpinfo
thanks for help, man!
