如何处理Symfony2 Beta上的表单集合？ [英] How to deal with Form Collection on Symfony2 Beta?

问题描述

我有一个实体User和一个实体Address。用户和地址之间存在一对多关系：

  class User 
 {
 / ** 
 * @orm：OneToMany（targetEntity =Address）
 * / 
 protected $ adresses; 
 
 [...] 
 
} 
  

我有一个类AddressType和类UserType：

  class UserType extends AbstractType 
 {
 public function buildForm（FormBuilder $ builder，array $ options）
 {
 $ builder-> add（'addresses'，'collection'，array（'type'=> new AddressType（）））; 
 
} 
 
 [...] 
} 
  

b $ b

在我的控制器中，我用下面的形式构建表单：

  $ form = $ this-& form.factory'） - > create（new UserType（））; 
  

...并创建视图：

  return array（'form'=> $ form-> createView（））; 
 

我在我的树枝模板中显示表单字段：

  {{form_errors（form.name）}} 
 {{form_label（form.name）}} 
 {{form_widget } 
 [...] 
  

好吧。现在，如何显示一个或多个地址的字段？ （它不是 {{for_widget（form.adresses.zipcode）}} 也不是 {{for_widget（form.adresses [0] .zipcode）}} ...）

有任何想法吗？

解决方案

这是我在表单模板中执行的操作：

  {{form_errors（form.addresses）}} 
 
 {％for form.addresses％} 
< div id ={ 'address％sDivId'| format（loop.index）}}class =userAddressItem> 
< h5>地址＃{{loop.index}}< / h5> 
 
 {{form_errors（address）}} 
 {{form_widget（address）}} 
< / div> 
 {％endfor％} 
  

我有一个小的action bar，允许用户添加和删除地址。它是一个简单的脚本，使用正确的HTML代码将新的div附加到容器中。对于HTML，我只是使用相同的输出具有Symfony但更新索引。例如，这将是 AddressType 表单的街道输入文本的输出：

< input id =user_addresses_0_streetname =user [addresses] [0] [street]...>

< input id = user_addresses_1_streetname =user [addresses] [1] [street]...>

注意： required =requiredmaxlength =255，但可根据您的需要进行更改。

需要更多的HTML代码来添加一个新的 AddressType 到浏览器的DOM，但这给你的一般想法。

I have an entity User and an entity Address. There is a relation One-to-Many between User and Address :

    class User
    {
        /**
        * @orm:OneToMany(targetEntity="Address")
        */
        protected $adresses;

        [...]

    }

I have a class AddressType, and class UserType :

    class UserType extends AbstractType
    {
        public function buildForm(FormBuilder $builder, array $options)
        {
            $builder->add('addresses', 'collection', array('type' => new AddressType()));

        }

        [...]
    }

In my controller, I build form with :

    $form = $this->get('form.factory')->create(new UserType()); 

... and create view with :

    return array('form' => $form->createView());

I display form field in my twig template with :

    {{ form_errors(form.name) }}
    {{ form_label(form.name) }}
    {{ form_widget(form.name) }}
    [...]

Okay. Now, how to display fields for one or more addresses ? (it's no {{ for_widget(form.adresses.zipcode) }} nor {{ for_widget(form.adresses[0].zipcode) }} ...)

Any ideas ?

解决方案

This is how I did it in my form template:

{{ form_errors(form.addresses) }}

{% for address in form.addresses %}
    <div id="{{ 'address%sDivId'|format(loop.index) }}" class="userAddressItem">
        <h5> Address #{{ loop.index }}</h5>

        {{ form_errors(address) }}
        {{ form_widget(address) }}
    </div>
{% endfor %}

And I have a small action bar, driven by jQuery, that lets the user add and remove addresses. It is a simple script appending a new div to the container with the right HTML code. For the HTML, I just used the same output has Symfony but with updated index. For example, this would be the output for the street input text of the AddressType form:

<input id="user_addresses_0_street" name="user[addresses][0][street]" ...>

Then, the next index Symfony will accept is 1 so the new input field you add would look like this:

<input id="user_addresses_1_street" name="user[addresses][1][street]" ...>

Note: The three dots are a remplacement for required="required" maxlength="255" but could change depending on your needs.

You will need more HTML code than that to add a whole new AddressType to the DOM of the browser but this give you the general idea.
