使用表单验证配置文件设置CodeIgniter错误消息

Question

CodeIgniter是否能够解释config/form_validation.php以显示相应的错误消息？

使用控制器时有一种验证方法：$this->form_validation->set_message('min_length', '{field} must have at least {param} characters.');

当前的验证规则（最后一个数组是我感兴趣的，如果有一种方法可以在与规则相同的数组中添加验证消息。）：

'users' => array(
        array(
            'field' => 'first_name',
            'label' => 'First Name',
            'rules' => 'trim|required'
        ),
        array(
            'field' => 'last_name',
            'label' => 'Last Name',
            'rules' => 'trim|required'
        ),
        array(
            'field' => 'email_address',
            'label' => 'Email Address',
            'rules' => 'trim|required|valid_email'
        ,   'messages'=> array('valid_email'=>'Please make sure your email is correct.')))

您可以阅读并按照下面链接中的给定示例。我认为这将帮助您。

Custom Error Messages - Form Validation Codeigniter

CodeIgniter允许添加验证消息，如文档中所述。数组如下：

'users' => array(
        array(
            'field' => 'first_name',
            'label' => 'First Name',
            'rules' => 'trim|required'
        ),
        array(
            'field' => 'last_name',
            'label' => 'Last Name',
            'rules' => 'trim|required'
        ),
        array(
            'field' => 'email_address',
            'label' => 'Email Address',
            'rules' => 'trim|required|valid_email'
        ,   'errors'=> array('valid_email'=>'Please make sure your email is correct.')))
