如何在Symfony 2中创建自定义表单
[英]How to create a custom form in Symfony 2
I have three entities : Service, Group, Agent.
我有三个实体：服务，组，代理。
Service => oneToMany => Group => oneToMany => Agent
Service => oneToMany => Group => oneToMany => Agent
Each of these entities already have a form. By the way, I would like to create a custom mergeForm which will contains a select field Service to choose and a select field Groupe in order to merge some of these entities. The Symfony 2 official cookbook is under maintenance, so I would like to know the way to create the custom Form in which I will be able to choose a Service (from all existing services) and to choose a Group (from all existing groups)
这些实体中的每一个都已有表格。顺便说一句，我想创建一个自定义mergeForm，它将包含一个选择字段服务以及一个选择字段Groupe以合并其中一些实体。 Symfony 2官方手册正在维护中，所以我想知道创建自定义表单的方法，在该表单中我将能够选择服务（来自所有现有服务）并选择一个组（来自所有现有组）

What you're looking for is probably entity field type. This will allow you to embed within the form a select field that points to the foreign entity. This is primarily useful for small collections.
您正在寻找的可能是实体字段类型。这将允许您在表单中嵌入指向外部实体的选择字段。这主要适用于小型集合。
When you start dealing with large collections, and find the need/desire to load entities with Javascript (e.g. The collection is to large to justify loading all on page-load), you'll have to look at Symfony2 Documentation: How to Embed a Collection of Forms.
当您开始处理大型集合时，发现需要/希望使用Javascript加载实体（例如，集合很大以证明在页面加载时加载所有内容），您将不得不查看Symfony2文档：如何嵌入表格集。
It's also worth noting that there is a pull request slated for Symfony 2.2 that is supposed to make dealing with this type of form easier.
同样值得注意的是，Symfony 2.2有一个拉动请求，应该可以更容易地处理这种类型的形式。
