我有一个预算表单，它在select字段中列出了来自客户端实体的数据。摘要、预算和客户是相互关联的。预算具有client_id列，即假定通过从所选客户端获取id值来存储它。
<form action="{{ path('panel_add_budget') }}" method="POST">
<strong>Cliente</strong>
<div class="form-group">
<select name="cdg_budget_type[client_id]" class="form-control">
{% for client in clients %}
<option value="{{ client.id }}">{{ client.name }}</option>
{% endfor %}
</select>
</div>
<div class="form-group">
{{ form_row(form.address) }}
</div>
<div class="form-group">
{{ form_row(form.installments) }}
</div>
<div class="form-group">
{{ form_row(form.check_days) }}
</div>
<div class="form-group">
{{ form_row(form.date_start) }}
</div>
<div class="form-group">
{{ form_row(form.total_value) }}
</div>
<button type="submit" class="btn btn-success">Adicionar</button>

最后，我的addAction，来自BudgetController:
public function addAction(Request $request)
{
$form = $this->createForm(new BudgetType());
if ($request->getMethod() == 'POST') {
$form->handleRequest($request);
if ($form->isValid()) {
$manager = $this->getDoctrine()->getManager();
$manager->persist($form->getData());
$manager->flush();
$this->addFlash('success', 'Novo orçamento adicionado');
return $this->redirect($this->generateUrl('panel_budgets'));
}
}
return $this->render('PanelBundle:Budget:add.html.twig', array(
'clients' => $manager->getRepository('PanelBundle:Client')->findAll(),
'form' => $form->createView()
));
}
提交表单时，会引发异常：
警告：spl_object_hash((要求参数1为对象，给定为整数
public function getEntityState($entity, $assume = null)
{
$oid = spl_object_hash($entity);
if (isset($this->entityStates[$oid])) {
return $this->entityStates[$oid];

这对我来说没有任何意义。我不知道该怎么办。别人的解决方案对我一点帮助都没有。如果你需要更多的代码，请问我，我会编辑它。谢谢。
我建议您在实体中使用注释，并开始使用formbuilder。还要向客户端实体添加__toString((方法！
您的实体：
namespace AppBundle'Entity;
use Doctrine'ORM'Mapping as ORM;
use Symfony'Component'Validator'Constraints as Assert;
use Doctrine'Common'Collections'ArrayCollection;
/**
* Client
*
* @ORM'Table()
* @ORM'Entity
*/
class Client
{
/**
* @var integer
*
* @ORM'Column(name="id", type="integer")
* @ORM'Id
* @ORM'GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM'Column(name="name", type="string", length=64)
*/
private $name;
// YOUR OTHER CLIENT FIELDS
/**
* @ORM'OneToMany(targetEntity="Budget", mappedBy="client")
**/
private $budgets;
public function __construct() {
$this->budgets = new ArrayCollection();
}
/* this function is required to present the entity as a string */
public function __toString() {
return $this->name;
}
}
第二：
namespace AppBundle'Entity;
use Doctrine'ORM'Mapping as ORM;
use Symfony'Component'Validator'Constraints as Assert;
/**
* Budget
*
* @ORM'Table()
* @ORM'Entity
*/
class Budget
{
/**
* @var integer
*
* @ORM'Column(name="id", type="integer")
* @ORM'Id
* @ORM'GeneratedValue(strategy="AUTO")
*/
private $id;
// YOUR BUDGET FIELDS
/**
* @ORM'ManyToOne(targetEntity="Client", inversedBy="budgets")
* @ORM'JoinColumn(name="client_id", referencedColumnName="id")
**/
private $client;
}
然后从项目主目录将以下命令放入控制台：(也许您必须在每个命令之前输入单词php(
app/console doctrine:generate:entities AppBundle
app/console doctrine:schema:update --force
app/console doctrine:generate:crud AppBundle:Client
( type YES by the question Do you want to generate the "write" actions [no]?)
app/console doctrine:generate:crud AppBundle:Budget
( type YES by the question Do you want to generate the "write" actions [no]?)
看看新的路线：
app/console router:debug
正如你所看到的，你可以浏览到
web/app_dev.php/client/和
web/app_dev.php/b预算/并查看！
然后打开/src/AppBundle/Form/BudgetType.php，你会发现这个规则：
$builder
->add('client')
;
这是将客户端属性添加到表单的地方。Symfony将此表单字段自动设置为实体表单类型。你也可以这样写：
$builder
->add('client', 'entity', array(
'class' => 'AppBundle:Client',
'empty_value' => '',
))
;
所以现在你可以在预算表中选择你的客户。
您可能已经注意到，这些命令还为您添加了一个ClientController和一个BudgetController。有关表单类型的更多信息，请参阅文档。
