Symfony2自定义表单 [英] Symfony2 custom form

问题描述

我的表单与从数据库加载的复选框（我使用实体字段类型）。复选框是区域和地区。我有以下数据库模式：

  + ------------------- ---------------- + 
 | id | parent_id |名称| 
 + ----------------------------------- + 
 | 1 | NULL |区域| 
 + ----------------------------------- + 
 | 2 | 1 |区| 
 + ----------------------------------- + 
 | 3 | 1 |另一个区| 
 + ----------------------------------- + 
 | 4 | NULL |另一个区域| 
 + ----------------------------------- + 
 | 5 | 4 |下一个区| 
 + ----------------------------------- + 
  

问题是我需要以下表单。怎么做？

 < b>区域< / b><！ - 从数据库加载 - > 
<！ - 按名称排序的描述 - > 
< input type =checkboxid =someIdvalue =3>< label for =someId>另一个区域< / label> 
< input type =checkboxid =someIdvalue =2>< label for =someId>区< / label> 
< b>另一个区域< / b><！ - 从数据库加载 - > 
<！ - 按名称排序的描述 - > 
< input type =checkboxid =someIdvalue =5>< label for =someId>下一个区域< / label> 
  

解决方案

感谢这个帖子我已经通过自定义渲染表单模板解决了这个问题。

I have form with checkboxes loaded from database (I use entity field type). Checkboxes are regions and districts. I have following database schema:

+-----------------------------------+
| id | parent_id | name             |
+-----------------------------------+
| 1  | NULL      | Region           |
+-----------------------------------+
| 2  | 1         | District         |
+-----------------------------------+
| 3  | 1         | Another district |
+-----------------------------------+
| 4  | NULL      | Another region   |
+-----------------------------------+
| 5  | 4         | Next district    |
+-----------------------------------+

Problem is that I need following form. How to do that?

<b>Region</b><!-- Loaded from database -->
<!-- Dictricts ordered by name -->
<input type="checkbox" id="someId" value="3"><label for="someId">Another district</label>
<input type="checkbox" id="someId" value="2"><label for="someId">District</label>
<b>Another region</b><!-- Loaded from database -->
<!-- Dictricts ordered by name -->
<input type="checkbox" id="someId" value="5"><label for="someId">Next district</label>
