如何在 symfony2 中创建自定义字段类型? [英] How can I make a custom field type in symfony2?

问题描述

我想在 symfony2 中创建一个名为 daterange 的自定义表单字段，它将扩展默认的 symfony 日期类型表单字段并将日期范围(开始日期和结束日期)放入两个不同的文本框.

解决方案

因为我不喜欢 twig 模板引擎这个例子只用于 PHP 模板

你需要做的是:

1. 新 TestBundle\Form\Extension\Core\Type\DateRangeType 扩展了 Symfony\Component\Form\AbstractType

   在这里你应该:
   一种.编写自己的 getParent、getName、buildForm 方法
   湾getParent 返回字段"
   C.getName 返回日期范围"
   d.buildForm 有 $builder->add('start', ...)->add('end', ...)->setAttribute('widget', 'daterange')
   

2. 将其添加到 DI(以 config.yml 为例)

<前>服务:form.type.daterange:类:TestBundle\Form\Extension\Core\Type\DateRangeType标签:- { 名称:form.type，别名:daterange }

3. 在 TestBundle/Resources/views/Form/daterange_widget.html.php 中为其创建新的小部件您可以以日期小部件为例.src/vendor/symfony/src/Symfony/Bundle/FrameworkBundle/Resources/views/Form/date_widget.html.php

4. 添加到配置(以config.yml为例)

<前>框架:模板:形式:资源:- 'TestBundle:Form'

如 nefo_x 所说的更多小部件定制，请查看表单定制.

I want to make a custom form field in symfony2 named daterange, which will extends the default symfony date type form field and take date range(start date and end date) into two different text-box.

解决方案

Cause I don't like twig template engine this example only for PHP templating

What you need is to make:

1. New TestBundle\Form\Extension\Core\Type\DateRangeType which extends Symfony\Component\Form\AbstractType

   Here you should:
   a. write your own getParent, getName, buildForm methods
   b. getParent return 'field'
   c. getName return 'daterange'
   d. buildForm has $builder->add('start', ...)->add('end', ...)->setAttribute('widget', 'daterange')
   

2. Add it to the DI (config.yml as example)

    services:
        form.type.daterange:
            class: TestBundle\Form\Extension\Core\Type\DateRangeType
            tags:
                -  { name: form.type, alias: daterange }

3. Create new widget for it in TestBundle/Resources/views/Form/daterange_widget.html.php you can take date widget as example. Src/vendor/symfony/src/Symfony/Bundle/FrameworkBundle/Resources/views/Form/date_widget.html.php

4. Add to config (config.yml as example)

   framework:
       templating:
           form:
               resources:
                   - 'TestBundle:Form'

And for more widget customization as nefo_x said check form customization.
