如何在Symfony 2中创建自定义表单

[英]How to create a custom form in Symfony 2

原文 2012-06-20 08:12:16 4 1 php/ symfony

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. 这些实体中的每一个都已有表格。 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. 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 ，以便合并其中一些实体。 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) Symfony 2官方手册正在维护中，所以我想知道如何创建自定义表单，我可以在其中选择服务（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 . 您正在寻找的可能是实体字段类型。 This will allow you to embed within the form a select field that points to the foreign entity. 这将允许您在表单中嵌入指向外部实体的选择字段。 This is primarily useful for small collections. 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 (eg 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 . 当你开始处理大型集合，并发现需要/希望用Javascript加载实体时（例如，集合很大，以证明在页面加载时加载所有内容），你将不得不看看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. 值得注意的是，Symfony 2.2有一个拉取请求，应该可以更轻松地处理这种类型的表单。
