Question

我的申请表中有登录表单。在某些情况下，我想从控制器传递数据。

表单以这种方式创建：

<?= $this->Form->create(null, ['url' => ['controller' => 'Users', 'action' => 'login']]); ?>
<?= $this->Form->input('email', ['label' => __('E-mail')]); ?>
<?= $this->Form->input('password', array('label' => __('Password'))); ?>

在控制器中，我想修复电子邮件字段的默认值，但经过多次尝试 set ， request-＆gt;数据等......无法找到如何做到这一点。

    $this->set('email', 'whatever');
    $this->set('User.email', 'whatever');
    $this->set('user.email', 'whatever');
    $this->request->data['user']['email'] = 'whatever';
    $this->request->data['User']['email'] = 'whatever';
    $this->set('user', $this->Accounts->Users->newEntity(['email' => 'whatever']));

在CakePHP 2中，这只是简单地写在$this->request->data;

上

$this->request->data['User']['email'] = 'whatever';

请注意，登录表单显示为元素，因此可以在应用程序视图中的任何位置重复使用。

Answer 1

您可以使用实体而不是直接访问$this->request->data数组。

试试这个脚本：

//declare a new entity of user
$user = $this->Users->newEntity();

//set the default data
$user->email = 'whatever@domain.com';
$user->username = 'whatever name';

//set the entity to the view vars
$this->set(compact('user'));

更新：

您也可以使用此行：$this->request->data['email'] = 'whatever';

代替：$this->request->data['User']['email'] = 'whatever';

Answer 2

如果数据已来自表单，并且您希望在发布之前修改数据。

$myData = $this->myData->newEntity();    
$this->request->data['field_name'] = "value";  
pr($this->request->getData());  // for display whole form data with changed data
$myData = $this->myData->patchEntity($myData, $this->request->getData());  
if ($this->myData->save($myData)) {  
    $this->Flash->success(__('Data has been saved.'));  
    return $this->redirect(['action' => 'index']);  
}
