仅在填写字段时更新密码 - Only update password if field is filled in

Only update password if field is filled in

本文关键字：更新密码写字段 | 更新日期: 2023-09-27

我的观点:

  <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'));
            }
        }
    }

当我提交带有空白密码的表单时，数据库中的哈希值仍然会发生变化。如果已填写新密码，如何只更新密码哈希值

谢谢。

编辑:$data['User']['password']总是一个哈希值，从不为空!

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

你有几个选择(从最差到最好，在我看来):

重命名字段并在保存前交换

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

在相等性检查中散列字符串

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

将哈希函数更改为不散列空密码的哈希函数[参见书中的配置]:

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

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'));
       }
}

您可以将$data中的变量unset

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'));
        }
    }
}

您可以尝试仅更新特定字段，基于IF大小写:

       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
       }

你可以使用一个行为来处理它:http://www.dereuromark.de/2011/08/25/working-with-passwords-in-cakephp/

你可以使用字段"pwd"并将confirm设置为false(如果你不想使用pwd_confirm字段)
