CodeIgniter-使用form_validation.php配置数组显示自定义验证错误

Question

I've seen several related questions posted on StackOverflow, but nobody seems to have found a solution.

I've been following the CodeIgniter user guide and several tutorials to create and validate a contact form using a custom form_validation.php config array. The validation works properly, except that it displays the default validation message over my custom message.

What am I missing?

Config - form_validation.php

<?php  defined('BASEPATH') OR exit('No direct script access allowed');

$config = array(
    'contact/index' => array(
        array(
                'field' => 'name',
                'label' => 'Name',
                'rules' => 'trim|required|alpha_numeric_spaces',
                'errors' => array(
                    'required' => 'Please enter a %s.',
                    'alpha' => 'Your name may only contain letters and spaces.',
                )
        ),
        array(
                'field' => 'email',
                'label' => 'Email',
                'rules' => 'trim|required|valid_email',
                'errors' => array(
                    'required' => 'Please enter an %s address.',
                    'valid_email' => 'Please enter a valid %s address.',
                )
        ),
        array(
                'field' => 'subject',
                'label' => 'Subject',
                'rules' => 'trim|required',
                'errors' => array(
                    'required' => 'Please enter a %s.',
                )
        ),
        array(
                'field' => 'message',
                'label' => 'Message',
                'rules' => 'trim|required',
                'errors' => array(
                    'required' => 'Please enter a %s.',
                )
        ),
        array(
                'field' => 'g-recaptcha-response',
                'label' => 'recaptcha',
                'rules' => 'callback_recaptcha',
                'errors' => array(
                    'recaptcha' => 'Click the checkbox to prove you\'re human.',
                )
        )
    )

Answer 1

I just figured it out. In the 'name' errors array in form_validation.php

'alpha' => 'Your name may only contain letters and spaces.',

needs to be changed to

'alpha_numeric_spaces' => 'Your name may only contain letters and spaces.',
