PHP Codeigniter url 路由：用于在 url 中注册进程的令牌

Question

注册过程后立即显示 link 以设置密码： http://website.de/main/complete/token/MTkyYTBiY2EyNWE2ZDYwOTdhN2U4NjJkMjZmYzYyNTA

问题是我无法显示此页面来完成注册过程。

有人知道为什么吗？我已经找了 2 个小时了...

控制器函数：

       public function complete()
        {                                   
        $token = base64_decode($this->uri->segment(4));       
        $cleanToken = $this->security->xss_clean($token);

        $user_info = $this->user_model->isTokenValid($cleanToken); //either false or array();           

        if(!$user_info){
            $this->session->set_flashdata('flash_message', 'Token is invalid or expired');
            redirect(base_url().'login');
        }            
        $data = array(
            'firstName'=> $user_info->first_name, 
            'email'=>$user_info->email, 
            'user_id'=>$user_info->id, 
            'token'=>$this->base64url_encode($token)
        );

        $this->form_validation->set_rules('password', 'Password', 'required|min_length[5]');
        $this->form_validation->set_rules('passconf', 'Password Confirmation', 'required|matches[password]');              

        if ($this->form_validation->run() == FALSE) {   
            $this->load->view('header');
            $this->load->view('complete', $data);
            $this->load->view('footer');
        }else{

            $this->load->library('password');                 
            $post = $this->input->post(NULL, TRUE);

            $cleanPost = $this->security->xss_clean($post);

            $hashed = $this->password->create_hash($cleanPost['password']);                
            $cleanPost['password'] = $hashed;
            unset($cleanPost['passconf']);
            $userInfo = $this->user_model->updateUserInfo($cleanPost);

            if(!$userInfo){
                $this->session->set_flashdata('flash_message', 'There was a problem updating your record');
                redirect(base_url().'login');
            }

            unset($userInfo->password);

            foreach($userInfo as $key=>$val){
                $this->session->set_userdata($key, $val);
            }
            redirect(base_url());

        }
    }


    public function register()
    {

        $this->form_validation->set_rules('firstname', 'First Name', 'required');
        $this->form_validation->set_rules('lastname', 'Last Name', 'required');    
        $this->form_validation->set_rules('email', 'Email', 'required|valid_email');    

        if ($this->form_validation->run() == FALSE) {   
            $this->load->view('header');
            $this->load->view('register');
            $this->load->view('footer');
        }else{                
            if($this->user_model->isDuplicate($this->input->post('email'))){
                $this->session->set_flashdata('flash_message', 'User email already exists');
                redirect(base_url().'login');
            }else{

                $clean = $this->security->xss_clean($this->input->post(NULL, TRUE));
                $id = $this->user_model->insertUser($clean); 
                $token = $this->user_model->insertToken($id);                                        

                $qstring = $this->base64url_encode($token);                    
                $url = base_url() . 'complete/token/' . $qstring;
                $link = '<a href="' . $url . '">' . $url . '</a>'; 

                $message = '';                     
                $message .= '<strong>You have signed up with our website</strong><br>';
                $message .= '<strong>Please click:</strong> ' . $link;                          
                echo $message; //send this in email
                exit;


            };              
        }
    }

模型函数：

    public function insertToken($user_id)
    {   
    $token = substr(sha1(rand()), 0, 30); 
    $date = date('Y-m-d');

    $string = array(
            'token'=> $token,
            'user_id'=>$user_id,
            'created'=>$date
        );
    $query = $this->db->insert_string('tokens',$string);
    $this->db->query($query);
    return $token . $user_id;

}

public function isTokenValid($token)
{
   $tkn = substr($token,0,30);
   $uid = substr($token,30);      

    $q = $this->db->get_where('tokens', array(
        'tokens.token' => $tkn, 
        'tokens.user_id' => $uid), 1);                         

    if($this->db->affected_rows() > 0){
        $row = $q->row();             

        $created = $row->created;
        $createdTS = strtotime($created);
        $today = date('Y-m-d'); 
        $todayTS = strtotime($today);

        if($createdTS != $todayTS){
            return false;
        }

        $user_info = $this->getUserInfo($row->user_id);
        return $user_info;

    }else{
        return false;
    }

}

你想做的是，用户注册成功后，显示him/her一个url完成注册对吗？

据我理解的问题，你可以这样做，

在你的控制器中，

$message = '';                     
$message .= '<strong>You have signed up with our website</strong><br>';
$message .= '<strong>Please click:</strong> ' . $link;

$data = array(
               'message' => $message 
          );

$this->load->view('header');
$this->load->view('complete', $data);
$this->load->view('footer');

并创建一个名为 complete.php 的视图

<html>
<head>
<title></title>
</head>
<body>
    <h1><?php echo $message;?></h1>
</body>
</html>

向视图添加动态数据 - https://www.codeigniter.com/userguide2/general/views.html
