一个小部件中的 Symfony 类别和子类别小部件

Question

我的架构中有两个关系，具有许多子类别的产品和具有许多类别的产品。所以我可以在我的 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));

这是工作。但我需要举例：

类别 1

子类别 1，子类别 2

类别2

类别3

子类别3，子类别4

我需要做的是，我可以检查类别和子类别。

谢谢！

回答

我让它手动。我从缓存文件 _form.php 中获取并重写它，添加类别和子类别复选框。比我在动作类中进行一些更改（手动设置和删除子类别和类别）。我使用答案中的代码，所以我检查一下！

检查这个：http://www.symfony-project.org/jobeet/1_4/Doctrine/en/06

更新：

你可以简单地在模板中：

$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();
   }
}

这应该可以正常工作，但这不是正确编程
