如何使用symfony2中的一个按钮提交多个相同类型的表单

我在todolist中显示了三种形式的任务类型

$task1 = new Task();
$form1 = $this->createForm(new MyForm('f1'), $task1);

$task2 = new Task('fo');
$form2 = $this->createForm(new MyForm('f2'), $task2);

$task3 = new Task();
$form3 = $this->createForm(new MyForm('f3'), $task3);

现在的问题是我只有一个提交按钮。如何在一个控制器中持久化这三个任务。用户还可以动态添加更多表单

---

那么解决这个问题的方法是什么呢？创建一个类，比如

TaskList

，它包含

任务的集合。然后创建包含
TaskType
类型的
TaskType
s。这样，您将拥有一个表单，其中包含您想要的任意多个任务。
为了完整起见，请在下面找到一个完整的示例

您应该创建一个表示所需表单的新模型。关键是，您可能不想影响条令（例如，请参阅条令：schema:update命令）。它可能会尝试为实际上不存在的实体创建一个表。为了避免这种情况，只需将模型类放在model文件夹下（\src\Acme\Bundle\DemoBundle\model\TaskList.php）

假设以下是TaskType表单类：

<?php

namespace Acme\Bundle\DemoBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class TaskType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('id', null, array('read_only' => true))
            ->add('name');
    }

    /**
     * @param OptionsResolverInterface $resolver
     */
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(
            array(
                'data_class' => 'Acme\Bundle\DemoBundle\Entity\Task'
            )
        );
    }

    /**
     * @return string
     */
    public function getName()
    {
        return 'acme_demo_task';
    }
}

和一个示例控制器：

public function indexAction($page)
{
    ini_set('xdebug.max_nesting_level', 300); // this might be useful with deeply nested forms

    $search = $this->getRequest()->get(
        'search',
        array(
            'name' => '',
            'date' => '',
            'lang' => $this->container->getParameter('acme_core.default_lang')
        )
    );

    /**
     * @var \Doctrine\ORM\EntityManager $em
     */
    $em = $this->getDoctrine()->getManager();

    $paginator = $this->get('knp_paginator');
    $pagination = $paginator->paginate(
        $em->getRepository('AcmeDemoBundle:Task')->getQueryFilteringByLangNameAndDate(
            $search['lang'],
            $search['name'],
            $search['date'] != '' ? new \DateTime($search['date']) : null
        ),
        $page,
        $this->getRequest()->get('elementsPerPage', 10)
    );

    $taskList = new TaskList();
    $taskList->setFromPagination($pagination);

    $form = $this->createForm('acme_demo_task_list', $taskList); // "acme_demo_task_list" has been defined in the services.yml file
    $form->handleRequest($this->getRequest());

    if ($form->isValid()) {
        foreach ($form->getData() as $task) {
            $em->merge($task);
        }
        $em->flush();
    }

    return $this->render(
        'AcmeDemoBundle:Task:index.html.twig',
        array(
            'search' => $search,
            'pagination' => $pagination,
            'form' => $form->createView()
        )
    );
}

我希望这有帮助
 我们遵循了“弗朗西斯科·卡苏拉”所展示的考试，考试效果非常好

出于orur目的，我们不需要分页，因此这就是我们填写集合的方式（在
控制器中）
：

对于那些需要自定义表单集合输出的用户，我们通过迭代
{%For forms in forms.children.stocks%}
来访问子表单Stocks'是表单生成器中字段的名称（在
StockListType
中）：

这就是我们最终在细枝视图中使用的内容：

{{ form_start(forms) }}

            <th>#</th>

            <th>Total</th>
            <th>Updated Toal</th>
        </thead>
        <tbody>
            {% set counter = 1 %}

您应该考虑使用
jQuery
执行此类任务。它允许您提交所有表单。购买jquery与信条和坚持有什么关系。你能给我一些链接让我明白你的意思吗
