使用表单生成器 symfony2 创建数组输入字段 [英] Create array input field with form builder symfony2

问题描述

我在 Symfony2 中使用表单构建器时遇到问题.确切地说，我需要输入字段是 html 数组，但我无法使用 createFormBuilder->add 创建它.这是我尝试过的:

$attributesForm = $this->createFormBuilder()->add('attribute[0]', 'text') ...

依此类推，但我收到以下异常:

<块引用>

名称属性[0]"包含非法字符.名称应以字母、> 数字或下划线开头，并且只能包含字母、数字、数字、下划线 ("_")、连字符 >("-") 和冒号 (":").

有什么好的解决方案，或者我必须手动创建字段?

提前致谢！

进一步澄清这一点......我想要生成这样的东西:

<div>名称<input type="text" name="name"></div><div>...</div><div>属性 0 <input type="text" name="attribute[0]"></div><div>属性1<input type="text" name="attribute[1]"></div><div>属性3<input type="text" name="attribute[3]"></div><ul><p><button type="submit">编辑</button></p>

帮助?

解决方案

您可以使用集合"字段类型创建输入字段数组.

I'm having a trouble with using Form builder in Symfony2. To be exact, I need input field that is html array, but I can't create it with createFormBuilder->add. Here is what I tried:

$attributesForm = $this->createFormBuilder()
        ->add('attribute[0]', 'text') ...

And so on, but I get the following exception:

The name "attribute[0]" contains illegal characters. Names should start with a letter, >digit or underscore and only contain letters, digits, numbers, underscores ("_"), hyphens >("-") and colons (":").

Is there any nice solution or I have to create fields manually?

Thanks in advance!

EDIT: to clarify this further... I want something like this to be generated:

<div id="msoft_adminbundle_offertype">
<div>Name <input type="text" name="name"></div>
<div>...</div>
<div>Attribute 0 <input type="text" name="attribute[0]"></div>
<div>Attribute 1 <input type="text" name="attribute[1]"></div>
<div>Attribute 3 <input type="text" name="attribute[3]"></div>
<ul>
    </ul>
<p>
    <button type="submit">Edit</button>
</p>

Help?

解决方案

You can create an array of input fields using the 'collection'-field type.

Documentation about how to use it can be found here:
