我正在使用 CodeIgniter 2.3.1 并在其中创建了一个form_validation.php
文件,config
内容如下。
<?php
$config = array(
array(
'field' => 'firstname',
'label' => 'First Name',
'rules' => 'required'
),
array(
'field' => 'lastname',
'label' => 'Last Name',
'rules' => 'required'
),
array(
'field' => 'email',
'label' => 'Email',
'rules' => 'required|valid_email|callback_unique_email'
),
array(
'field' => 'password',
'label' => 'Password',
'rules' => 'required|matches[confirm_password]'
),
array(
'field' => 'confirm_password',
'label' => 'Confirm Password',
'rules' => 'required'
)
);
function unique_email($email) {
if($email == 'm@gmail.com') {
$this->form_validation->set_message('unique_email', 'Hello World !');
return false;
}
}
?>
并检查控制器的form_validation
输入register
功能。user
代码如下。
public function register() {
$this->load->helper('form');
$data['message'] = '';
if($this->input->post('submit')) {
$this->load->library('form_validation');
if($this->form_validation->run() == FALSE) {
$data['message'] = 'User could not be saved.';
} else {
$user_data['firstname'] = $this->input->post('firstname');
$user_data['lastname'] = $this->input->post('lastname');
$user_data['email'] = $this->input->post('email');
$user_data['password'] = md5($this->input->post('password'));
if($this->user_model->insert($user_data)) {
if($this->user_model->login($user_data)) {
$this->session->set_flashdata('message', 'User saved successfully.');
redirect('/user', 'refresh');
}
}
}
}
$this->load->view('user/register', $data);
}
但我没有收到自定义方法的验证消息。请建议我怎么做?作品更受赞赏。
