我在尝试请求从表单发送的数据时遇到了一些问题。当我检查$this->request->data时，它表示它是一个空数组，所以我想我会尝试debug($this->request)并显示数据为array(0)。我不确定为什么会这样。我提供了我的模型 - 视图 - 控制器文件。
修改
经过一些进一步的测试，我发现我的问题在于
if(!empty($this->request->data))
UsersController.php中的。我不知道为什么，但data[Reference][]形式没有到达控制器。我已经添加了以下代码的片段。
（Controller）UsersController.php：
public function send_invitation() {
$user = $this->Auth->user();
$this->layout = "dashboard";
// debug($this->request);
if (!empty($this->request->data)) {
...
} else {
echo 'there is no data';
}
$this->set("user", $user);
}
（查看）send_invitation.php：
<div class="dashboard-container-right">
<div class="dashboard-innerright">
<div class="upper-dashboard"><h1> <?php echo __("Send Invitations"); ?> </h1></div>
<div class="botm-forcolor">
<div class="midd-dashord">
<?php echo __("Your Referral Code is"); ?> <strong><?php echo $user["referral_code"];?> </strong>
<div class="invite-content">
<!--- Instructor Login -->
<div class="tab-pane active" id="instructor">
<?php echo $this->Form->create('Reference' , array('id'=>'send_invites' , 'url' => array('controller' => 'users', 'action' => 'send_invitation' ) , 'novalidate'=>'novalidate')); ?>
<?php $form=$this->Form;?>
<div class="padding_15tabs">
<div class="col-md-12 show-grid row">
<?php $name=__("Name"); ?>
<?php echo $form->input('Reference.name',array('class'=>'col-xs-12 col-sm-12 col-lg-12 text-style', 'placeholder'=>$name, 'div' => false,'label'=>false))?>
</div>
<div class="col-md-12 show-grid row">
<?php $email=__("Email"); ?>
<?php echo $form->input('Reference.email',array('class'=>'col-xs-12 col-sm-12 col-lg-12 text-style', 'placeholder'=>$email, 'div' => false,'label'=>false))?>
</div>
<div class="col-md-12 show-grid row">
<?php $message=__("Message"); ?>
<?php echo $form->textarea('Reference.message',array('class'=>'col-xs-12 col-sm-12 col-lg-12 text-style', 'placeholder'=>$message, 'div' => false,'label'=>false))?>
</div>
<input type="hidden" name="data[Reference][user_id]" value="<?php echo $user['id']; ?>">
<div class="col-md-12 show-grid row">
<div class="align-center">

</span>
</div>
</div>
</div>
</form>
</div>
</div>
</div>
</div>
</div>
（型号）Reference.php：
class Reference extends AppModel {
public $useTable = 'references';
public $name = 'Reference';
public $belongsTo = array('User' => array(
'className' => 'User',
'foreignKey' => 'user_id'

看起来好像在使用SecurityComponent（可能在AppController::$components中加载？）。
此组件要求您使用FormHelper创建表单，以及SecurityComponent文档中提到的其他限制。
如果您希望禁用特定操作的安全约束，可以将方法添加到：
$this->Security->unlockedActions()
如Disabling CSRF and Post Data Validation For Specific Actions中所述。

此安全组件有时可能会造成混淆并导致此类问题。我建议的是在Model / AppModel.php中编写下面提到的代码。它的效果一样好！
public function beforeSave（$ options = array（））{
if(isset($this->data)){
foreach($this->data as $key=>&$result_array){
foreach($result_array as $field=>&$value){
if($value)
$value = filter_var ($value, FILTER_SANITIZE_STRING, FILTER_FLAG_NO_ENCODE_QUOTES);
}
}
}
return true;
}
