我尝试在CakePHP v.2.7中找到一种好方法来处理管理面板“编辑用户”.

需要说明的是：我希望能够编辑我的用户而不必覆盖他们的密码,但是cakePHP验证程序工具不允许我做我想做的事…

我已经看过CakePHP: Edit Users without changing password和Updating user email and password with CakePHP了,但看起来确实很脏：

>第一个不将规则应用于onUpdate
>第二个显示哈希(只是不… u_u“)

还有别的办法吗？ (行越少越好)

解决方法:

TL; DR：

视图

// add in your view `app/View/Users/edit.ctp`
// a 'fake' field you'll only use on the controller
echo $this->Form->input('new_password');

调节器

// add in your controller `app/Model/User.php@edit()`
// if we have a new password, create key `password` in data
if(!empty($new_password = $this->request->data['User']['new_password']))
  $this->request->data['User']['password'] = $new_password;
else // else, we remove the rules on password
  $this->User->validator()->remove('password');

好的,我终于得到了想要的东西,这是我的代码：

在您的app / View / Users / edit.ctp上,将一个字段添加到表单中(自定义字段,请勿将其添加到数据库中)

<?php
// app/View/Users/edit.ctp
echo $this->Form->create('User');
// your other fields
// a 'fake' field you'll only use on the controller
echo $this->Form->input('new_password');

不要更改您的app / Model / User.php；这是我的：

<?php
// app/Model/User.php
App::uses('AuthComponent', 'Controller/Component');

class User extends AppModel {
  public $validate = array(
    // [...] other rules
    'password' => array(
      'passwordLength'=>array(
        'rule' => array('minLength', 8),
        'message' => 'Too short...',
        ),
      'passwordNotBlank'=>array(
        'rule' => 'notBlank',
        'required' => true,
        'allowEmpty' => false,
        'message' => 'A password is required',
        ),
    ),
  );

  public function beforeSave($options = array()) {
    if (!empty($pwd = $this->data[$this->alias]['password']))
      $this->data[$this->alias]['password'] = AuthComponent::password($pwd);

    return true;
  }
}

然后在您的app / Controller / UsersController.php中使用以下代码：

<?php
public function edit($id = null) {
  $this->User->id = $id;

  if (!$this->User->exists())
    throw new NotFoundException(__('Invalid user'));

  if ($this->request->is('post') || $this->request->is('put')) {
      // IMPORTANT >>>>>>>>>>>
      // if we have a new password, create key `password` in data
    if(!empty($new_password = $this->request->data['User']['new_password']))
      $this->request->data['User']['password'] = $new_password;
    else // else, we remove the rules on password
      $this->User->validator()->remove('password');
      // <<<<<<<<<<<<<<<<<<<<<

      // then we try to save
    if ($this->User->save($this->request->data)) {
      $this->Flash->success(__('The user has been updated'));
      $this->redirect(array('action' => 'index'));
    }
    else
      $this->Flash->warning(__('The user could not be updated.'));
  }
  else {
    $this->request->data = $this->User->read(null, $id);
    unset($this->request->data['User']['password']);
  }
}

使用4条重要的代码行,您现在可以根据需要设置新密码或禁用密码验证.
