Question

我目前正在尝试允许用户在登录时更新自己的详细信息。到目前为止，用户只能编辑用户1，但表单也不会填充。我希望能够允许特定会话用户更改其详细信息，但不知道该怎么做。任何指导都将不胜感激，谢谢！

登录控制器 - Login.php

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Login extends CI_Controller{

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


    public function index()
    {
         if(($this->session->userdata('user_name')!=""))
    {
            $this->welcome();
    }
    else    {
         $data['title']= 'MVC Application';
            $this->load->view('templates/header', $data);
            $this->load->view('templates/nav');
            $this->load->view('login/signin', $data);
            $this->load->view('templates/footer');
            }
    }


    public function welcome()
    {

        $data['title']= 'MVC Application';
        $this->load->view('templates/header', $data);
        $this->load->view('templates/nav');
        $this->load->view('login/welcome', $data);
        $this->load->view('templates/footer');

    }


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

$this->load->library('form_validation');
// field name, error message, validation rules
$this->form_validation->set_rules('email', 'Your Email', 'trim|required');
$this->form_validation->set_rules('pass', 'Password', 'trim|required');

if($this->form_validation->run() == FALSE)
{
$this->index();
}
else{
 $this->login_model->login($email,$password);
    $this->welcome(); 
} 
}

public function logout()
{
$newdata = array(
'id'   =>'',
'username'  =>'',
'email'     => '',
'logged_in' => FALSE,
 );
$this->session->unset_userdata($newdata );
session_destroy();
redirect('login/index');
}

function update() 
{   $data['title']= 'MVC Application';
     $this->load->view('templates/header', $data);
    $this->load->view('templates/nav');
        $this->load->view('login/update', $data);
        $this->load->view('templates/footer');

    $data = array (
        'username' => $this->input->post('username'),
        'email' => $this->input->post('email'),
        'password' => $this->input->post('password') 
    );
    $this->load->model('login_model');
    $this->login_model->update($data);
}
}
?>

登录模型 - Login_model.php

  <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
   class Login_model extends CI_Model {

    public function __construct()
    {
            $this->load->database();
    }

    public function login($email, $password)
    {
    $this->db->where("email",$email);
    $this->db->where("password",$password);
    $query=$this->db->get("mvc_user");

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

  function update($data) 
 {
 $this->db->where('id', 1);
 $this->db->update('mvc_user', $data);              
 }
 }
?>

更新视图（位于登录文件夹中）update.php

<div class="six columns">
<?php echo form_open('login/update'); ?>

<p>
<label for="user_name">Username</label>
<input type="text" name="user_name" id="user_name" />
</p>
<p>
<label for="user_email">Email</label>
<input type="text" name="user_email" id="user_email" />
</p>
<p>
<label for="user_password">Password</label>
<input type="text" name="user_password" id="user_password" />
</p>
<p><input type="submit" value="Save" /></p>

<?php echo form_close(); ?>
</div>

首先，您需要将数据从Login控制器传递到视图，以便您可以预先填充表单字段：

function update() {

    // Prepare data to pass to the view
    $data = array (
        'title' => 'MVC Application',
        'username' => $this->session->userdata('username'),
        'email' => $this->session->userdata('email'),
        'password' => $this->session->userdata('password') 
    );

    $this->load->view('templates/header', $data);
    $this->load->view('templates/nav');
    $this->load->view('login/update', $data);
    $this->load->view('templates/footer');

    $data = array (
        'username' => $this->input->post('username'),
        'email' => $this->input->post('email'),
        'password' => $this->input->post('password') 
    );
    $this->load->model('login_model');
    $this->login_model->update($data);
}

然后，视图可以作为单个变量访问数组元素并预先填充输入字段：

<div class="six columns">
<?php echo form_open('login/update'); ?>
<p>
<label for="username">Username</label>
<input type="text" name="username" id="username" value="<?php echo $username; ?>" />
</p>
<p>
<label for="email">Email</label>
<input type="text" name="email" id="email" value="<?php echo $email; ?>" />
</p>
<p>
<label for="password">Password</label>
<input type="text" name="password" id="password" value="<?php echo $password; ?>" />
</p>
<p><input type="submit" value="Save" /></p>

<?php echo form_close(); ?>
</div>

要在Login_model.php中保存用户的新数据，只需从会话中获取ID：

function update($data) {
    $my_id = $this->session->userdata('id');
    if($my_id !== false) { // Just making sure we're logged in
        $this->db->where('id', $my_id);
        $this->db->update('mvc_user', $data);              
    }
}
