Symfony類別和子類別小部件在一個小部件中

Question

我在我的模式中有兩個關係，產品有許多子類別和有很多類別的產品。所以，我可以讓我的productForm.class.php

$this->widgetSchema['subcategory_list'] = new sfWidgetFormDoctrineChoice(array('model' => 'Subcategory', 'add_empty' => false, 'multiple' => true,'expanded' => true)); 

$this->widgetSchema['category_list'] = new sfWidgetFormDoctrineChoice(array('model' => 'Category', 'add_empty' => false, 'multiple' => true,'expanded' => true)); 

而且這是工作。但我需要做，例如：

組別

子類別1，subcategory2

產品組別

類別3

subcategory3，subcategory4

我需要做的是，我可以檢查類別和子類別。

謝謝！

ANSWER

我讓它手冊。我從緩存文件_form.php中獲取並重寫它，添加類別和子類別複選框。比我在操作類中做了一些更改（手動設置和刪除子類別和類別）。我使用答案代碼，所以我檢查它！

檢查：http://www.symfony-project.org/jobeet/1_4/Doctrine/en/06

更新：

，你可以很簡單的模板：

$categories = CategoryTable::getInstance()->findAll(); 

foreach ($categories as $category) { 
    echo $category->getName(); 
    $subcategory = SubcategoryTable::getInstance()->findBy('category_id', $category->getId()); 
    foreach($subcategory as $sub){ 
     echo $sub->getName(); 
    } 
} 

這應該工作正常，但是這個心不是正確編程
