仅填写字段时才更新密码

Question

我的看法：

  <tr>
    <td>Username</td>
    <td><?php echo $this->Form->input('User.username', array('label' => '')); ?></td>
  </tr>
  <tr>
    <td>Password</td>
    <td><?php echo $this->Form->password('User.password', array('label' => '', 'value'=>'')); ?></td>
  </tr>

我的控制器：

    function edit($id = null) {

        $this->User->id = $id;

        $data = $this->data;
#       print_r($data);

        if (empty($data)) {
            $this->data = $this->User->read();
        } else {
            if ($this->User->save($data)) {
                $this->Session->setFlash('The user details have been updated.');
                $this->redirect(array('action' => 'index'));
            }
        }

    }

在我使用空白密码提交表单时，数据库中的哈希值仍会发生变化。 如果填写了新密码，我该如何才更新密码哈希。

谢谢。

编辑：$ data ['用户'] ['密码']始终是一个哈希，永远不会空！

Answer 1

如果密码字段为空则取消设置。

else {
       if(empty($data['User']['password']))
       {
          unset($data['User']['password']);
       }
       if ($this->User->save($data)) {
          $this->Session->setFlash('The user details have been updated.');
           $this->redirect(array('action' => 'index'));
       }
}

CakePHP 1.3自动散列password字段。 CakePHP 2.0没有。

您有几个选择（在我看来，从最差到最好）：

1. 重命名您的字段并在保存之前进行交换

    if ($data['User']['new_password'] != '') { $data['User']['password'] = $this->Auth->password($data['User']['new_password']); } 

2. 在等式检查中散列字符串

    if ($data['User']['password'] == $this->Auth->password('')) { unset($data['User']['password']); } 

3. 将散列函数更改为不散列空密码的函数[参见本书的配置]：

    function hashPasswords($data) { if (!empty($this->data['User']['password'])) { $this->data['User']['password'] = $this->Auth->password($this->data['User']['password']); } return $data; }

您可以从$data unset变量

function edit($id = null) {

    $this->User->id = $id;

    $data = $this->data;

    if (empty($data)) {
        $this->data = $this->User->read();
    } else {
        if($data['User']['password'] == ''){
            unset($data['User']['password']);
        }
        if ($this->User->save($data)) {
            $this->Session->setFlash('The user details have been updated.');
            $this->redirect(array('action' => 'index'));
        }
    }
}

您可以尝试根据IF情况仅更新特定字段：

       if(empty($data['User']['password']))
       {
          $this->User->id = $user_i; // specify which User to update
          //update only username
          $this->User->save(array('User'=>array('User.username'=>$data['User']['username'])));
       }
       else{
          //save as before
       }

您可以使用为您处理它的行为： http ： //www.dereuromark.de/2011/08/25/working-with-passwords-in-cakephp/

然后你会使用字段“pwd”并将confirm设置为false（如果你不想要pwd_confirm字段）
