尝试设置回叫功能,但由于某种原因它无法正常工作。不知道我在这里做错了什么。

在下面的控制器中查找registration()和_email_check($ str)函数。

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class Register extends CI_Controller {

public function __construct() 
{
    parent::__construct();
    $this -> load -> model('user_model');
}

public function index() 
{
    if (($this -> session -> userdata('user_name') != "")) {
        redirect('dashboard');
    } 
    else
    {
        $data['title'] = 'Register';
        $this -> load -> view('shared/header_view', $data);
        $this -> load -> view("registration.php", $data);
        $this -> load -> view('shared/footer_view', $data);
    }
}

public function login() 
{
    $email = $this -> input -> post('email');
    $password = $this -> input -> post('pass');

    $result = $this -> user_model -> login($email, $password);
    if ($result)
        redirect('dashboard');
    else
        $this -> index();
}

public function registration() 
{
    $this -> load -> library('form_validation');
    // field name, error message, validation rules
    $this -> form_validation -> set_rules('user_name', 'User Name', 'trim|required|min_length[4]|xss_clean');
    $this -> form_validation -> set_rules('email_address', 'Your Email', 'trim|required|valid_email', 'callback__email_check');
    $this -> form_validation -> set_rules('password', 'Password', 'trim|required|min_length[4]|max_length[32]');
    $this -> form_validation -> set_rules('con_password', 'Password Confirmation', 'trim|required|matches[password]');

    if ($this -> form_validation -> run() == FALSE) 
    {
        $this -> index();
    } 
    else 
    {
        $this -> user_model -> add_user();

        $email = $this -> input -> post('email');
        $password = $this -> input -> post('pass');            

        $result = $this -> user_model -> login($email, $password);
        if ($result)
        {
            redirect('dashboard');  
        }          
    }        
}

// Checks that Email Address is not in use
public function _email_check($str)
{
    // return true if the address is indeed a new address
    $this -> db -> where('email', $str);
    $found = $this -> db -> get('user') -> num_results(); // this returns the number of rows having the same address.

    if ($found!=0)
    {
        $this -> form_validation -> set_message('email_check', 'Email Address is already in use');
        return false;  // more than 0 rows found. the callback fails.
    }
    else
    {
        return true;   // 0 rows found. callback is ok.
    }
}

public function logout() 
{
    $newdata = array('user_id' => '', 'user_name' => '', 'user_email' => '', 'logged_in' => FALSE, );
    $this -> session -> unset_userdata($newdata);
    $this -> session -> sess_destroy();
    redirect(base_url());
}
}

如果需要,这是MODEL:

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class User_model extends CI_Model {

public function __construct() {
    parent::__construct();
}

function login($email, $password) 
{
    $this -> db -> where("email", $email);
    $this -> db -> where("password", $password);

    $query = $this -> db -> get("user");
    if ($query -> num_rows() > 0) 
    {
        foreach ($query->result() as $rows) 
        {
            //add all data to session
            $newdata = array(
                'user_id' => $rows -> id,
                'user_name' => $rows -> username,
                'user_email' => $rows -> email,
                'logged_in' => TRUE,
            );
        }
        $this -> session -> set_userdata($newdata);
        return true;
    }
    return false;
}

public function add_user() 
{
    $data = array(
        'username' => $this -> input -> post('user_name'),
        'email' => $this -> input -> post('email_address'),
        'password' => $this -> input -> post('password'),
    );
    $this -> db -> insert('user', $data);
}
}

呃......刚刚告诉你要排除故障,问题是你正在调用回调错误。

    $this -> form_validation -> set_rules('email_address', 'Your Email', 'trim|required|valid_email|callback__email_check')
