symfony2中同一实体的形式为多行 [英] multiple rows in form for the same entity in symfony2

问题描述

我创建了一个包含多行的简单表单:

I create a simple form with multiple rows:

控制器:

public function indexAction() 
{
    $repository = $this->getDoctrine()->getRepository('MyBundle:Product');
    $products = $repository->findAll();

    foreach ($products as $product) {
        $forms[] = $this->createForm(new ProductType, $product)->createView();
    }

    return $this->render('MBundle:Default:index.html.twig', array('form' => $forms);        

}

我在一根小树枝上渲染它:

I render this in a twig:

<form action="{{ path('_submit') }}" method="post">
{% for key, formData in forms %}
    {{ form_row(formData.id) }}
    {{ form_row(formData.name) }}
    {{ form_row(formData.nameEnglish) }}
    <br clear="all" />
{% endfor %}
</form>

当我提交表单时，我的每个输入字段集都具有相同的名称属性，而我仅获得最后一个属性.如何获取所有行并在我的SubmitAction()控制器中对其进行验证?每个输入都需要有唯一的名称，对吗? ...也许我需要以某种方式设置name ="something [name] []"，但该怎么做?

When i submit form each of my input field set has the same name attributes and i get only the last one. How to grab all the rows and validate them in my submitAction() controller? Each input needs to have unique name, right? ... and perhaps i need to set somehow name="something[name][]" but how to do it?

推荐答案

Ok Cerad的评论正确，我们必须为此使用collection.起初听起来似乎是胡说八道，但这是正确的.我花了一些时间才得以解决.

Ok Cerad was right with his comment and we have to use collection for this. It may sound like a nonsense at first but it kinda is right. It took me a while to get head around it.

所以我必须创建一个ProductsType，它是一个arrayCollection并插入每个Product. (就像在带有Task和标签的文档中一样)

So i had to create a ProductsType which is an arrayCollection and inserts each Product. (just like in documentation with Task and tags)

我曾经用过:

$repository = $this->getDoctrine()->getRepository('ExampleBundle:Product');
$products = $repository->findAll();

$productCollection = new Products;

foreach ($products as $product) {
    $productCollection->getProducts()->add($product);
}

$collection = $this->createForm(new ProductsType, $productCollection);

return $this->render('ExampleBundle:Default:index.html.twig', array(
    'collection' => $collection->createView()
        ));

然后在树枝上我做

<div class="products">
    {% for product in collection.products %}
        {{ form_row(product.id) }}
        {{ form_row(product.name) }}
        {{ form_row(product.description) }}
        <br clear="all" />
    {% endfor %}
</div>    

工作完成.

甚至您也可以通过以下方式将主题应用于每一行:

And even you can apply themes to each row by this:

{% block _productsType_products_entry_name_row %}
    <div class="yourDivName">{{ block('form_widget') }}</div>
{% endblock %}
{% block _productsType_products_entry_description_row %}
    <div class="yourDivDescription">{{ block('form_widget') }}</div>
{% endblock %}

很酷的东西！
