爲什麼我得到空數組，當我看到數據

Question

我有這個在我的形式

<?php 

echo $this->Form->create('Vendor', array(
'url' => array_merge(array('action' => 'index'), $this->params['pass']) 
)); 
echo $this->Form->input('vendor_name', array('div' => false,'empty'=>true)); 
echo $this->Form->input('is_finalized', array('div' => false,'empty'=>true)); 
echo $this->Form->submit(__('Search', true), array('div' => false)); 
echo $this->Form->end(); 

?> 

，我有這個在我的控制器

var_dump($this->request); 

$這個 - >請求中的數據財產它，當我看着它的var_dump。請參閱下面的轉儲。但是當我做這個 的var_dump（$這個 - >請求 - >數據）;我得到一個空數組。你可以看到下面的數據是有公共的$這個 - >請求的var_dump
