唯一的電子郵件地址驗證

Question

我一直在調整我從教程和其他帖子看到的唯一的電子郵件驗證代碼。然而，對我的代碼來說，沒有任何東西可以完美工作

public function register_client($post_obj) 
{ 
    //client registration 
    $record = array 
    (
     'first_name'  => $post_obj['c_fname'], 
     'last_name'   => $post_obj['c_lname'], 
     'email_address'  => $post_obj['c_eadd'], 
     'password'   => $post_obj['c_pword'], 
     'address'   => $post_obj['c_add'], 
     'tagline'   => $post_obj['c_tagline'], 
     'profile'   => $post_obj['c_profile'], 
     'interests'   => $post_obj['c_interest'], 
     'billing_mode'  => $post_obj['c_bmode'] 
    ); 
    $this->db->insert('client', $record); 
} 

在我的控制器

我有這樣的：

public function client_signup_submit() 
{ 
    // completes client registration 

    /*$post_email = $this->input->post('c_eadd'); 
    $this->form_validation->set_rules('c_eadd', 'Email Address', 'required|trim|xss_clean|valid_email|callback_check_duplicate_email[' . $post_email . ']'); 
    $this->form_validation->set_message('check_duplicate_email', 'This email already exits. Please write a new email.'); 

    if ($this->form_validation->run() == FALSE) { 
    // validation failed then do that 
    $this->load->view('client_signup'); 
    } else */ 
    //$this->form_validation->set_rules('c_eadd',Email,'trim|xss_clean|required|valid_email|callback_check_email_exists'); 
    $this->inspire_model->register_client($_POST); 
    redirect("in/client?message=Client Account Registration Completed."); 
} 

我評論過的幾行，因爲他們並沒有無論如何工作。我檢查了我的系統/庫/ form_validation，它似乎是正確設置。

爲什麼不做什麼文檔說：is_unique[users.email]其中users是表和email是您正在檢查的字段。 http://ellislab.com/codeigniter/user-guide/libraries/form_validation.html

$this->form_validation->set_rules('c_eadd', 
    'Email Address', 
    'required|trim|xss_clean|valid_email|is_unique[users.email]');
