CodeIgniter - 使用form_validation.php配置數組顯示自定義驗證錯誤

Question

我在StackOverflow上看到了幾個相關的問題，但似乎沒有人找到解決方案。

我一直在關注CodeIgniter用戶指南和幾個教程，使用自定義的form_validation.php配置數組來創建和驗證聯繫表單。驗證工作正常，除了它顯示我的自定義消息的默認驗證消息。

我錯過了什麼？

配置 - 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.', 
       ) 
     ) 
    ) 
); 

控制器 - Contact.php

     $data['title'] = 'Contact Me'; 
     $data['description'] = 'Use this contact form.'; 
     $data['siteKey'] = $this->config->item('recaptcha-site-key');

      $this->email->reply_to($reply_to_email); 
      $this->email->subject($subject);

      if ($this->email->send()) 
      { 
       $this->session->set_flashdata('msg','<div class="result">Your message has been successfully delivered.</div>'); 
       redirect('contact/index'); 
      } 
      else

       redirect('contact/index'); 
      } 
     } 
    }

    { 
     $this->load->library('Recaptcha'); 

     if (!$this->recaptcha->verify($response)) { 
      return FALSE; 
     } 
     else 
     { 
      return TRUE; 
     } 
    } 
} 
?>

Answer 1

我想通了。在form_validation.php

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

的 '名稱' 的錯誤陣列

需要被改變到

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