回调函数在 codeigniter 中不起作用

Question

我使用了回调函数来检查电子邮件是否处于活动状态：我的控制器没有访问回调函数。

我的控制器代码：

     function index() { 
    //Session redirection
    header('Last-Modified:'.gmdate('D, d M Y H:i:s').'GMT');
    header('Cache-Control: no-store, no-cache, must-revalidate');
    header('Cache-Control: post-check=0, pre-check=0',false);
    header('Pragma: no-cache');
    $this->session->unset_userdata('created_user_id');
    $this->session->unset_userdata('created_user_type');
    $this->session->unset_userdata('edit_user_type');
    if ($this->input->server('REQUEST_METHOD') === 'POST'){
    $this->form_validation->set_rules('email', 'Email ID', 'trim|required|valid_email');
    $this->form_validation->set_rules('terms', 'Terms', 'trim|required');
        if($this->input->post('email'))
        { 
        $this->form_validation->set_rules('email', 'Email ID', 'callback_email_check');
        } echo "out"; die;
    $this->form_validation->set_error_delimiters('<div class="error_user" style="color:red">', '</div>');
    if($this->form_validation->run()){ 
                if($this->input->post('Join')!="") {
                $this->session->set_userdata('join_email', $this->input->post('email'));
                    redirect(base_url().'caregivers/my-account');
                }
        }
    }
    $this->load->view('site/landing-page');  

}

我的回调函数代码：

    public function email_check(){   
    $get_status = $this->web_user_model->get_status($this->input->post('email'));   
    if($get_status['is_active']=='1')
    {
        $this->form_validation->set_message('email_check','Email ID already Exits');
        return FALSE;
    }else{
        return TRUE;
    }

}

我不知道我哪里做错了。谁能帮我？？？提前致谢..

您设置了两次验证规则：

$this->form_validation->set_rules('email', 'Email ID', 'trim|required|valid_email');
....
if($this->input->post('email'))
{ 
    $this->form_validation->set_rules('email', 'Email ID', 'callback_email_check');
 }

这是无用的，因为您已经将电子邮件字段设置为必填，因此验证规则已经检查了 if。

尝试：

$this->form_validation->set_rules('email', 'Email ID', 'trim|required|valid_email|callback_email_check');

你的回调函数也应该有一个参数

public function email_check($email)
{
     $get_status = $this->web_user_model->get_status($email);
     ...

回调函数在 codeigniter 中不起作用
