我需要一些帮助，我会做一个表单来改变用户在应用程序中的角色。
我使用Symfony 3.1.X的"默认"包安全性。
实际上我可以检索DB中的所有角色并显示它们，我也对数据进行了一些处理，但我仍然卡住了显示问题，当我显示表单时，Twig bundle继续显示一些已经显示在下面的标签。
我该如何解决这个问题?
下面是我的代码:
<<p> 显示模板/kbd> {% extends 'admin/base.admin.html.twig' %}
{% block body %}
<section class="container">
{{ user.pseudo }} |
{{ dump(user, form.roles) }}
{{ form_start(form) }}
{% for role in user.roles %}
{% if form.roles.children[role] is defined %}
{{ form_label(form.roles.children[role]) }}
{{ form_widget(form.roles.children[role], {'attr':{'checked':true}}) }}
{% else %}
{{ form_label(form.roles) }}
{{ form_widget(form.roles) }}
{% endif %}
{% endfor %}
{{ form_end(form) }}
</section>
<div class="well">
{% for key, role in form.roles.children %}
{{ dump(key) }}
{% endfor %}
</div>
{% endblock %}
这是我的表单
<?php
namespace AppBundle'Form;
use AppBundle'Entity'MembersEntity;
use AppBundle'Entity'RoleEntity;
use Symfony'Bridge'Doctrine'Form'Type'EntityType;
use Symfony'Component'Form'AbstractType;
use Symfony'Component'Form'Extension'Core'Type'SubmitType;
use Symfony'Component'Form'FormBuilderInterface;
use Symfony'Component'OptionsResolver'OptionsResolver;
class ChangeRoleForm extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('roles', EntityType::class, array(
'class' => RoleEntity::class,
'choice_label' => 'nameRole',
'multiple' => true,
'expanded' => true,
'choice_value' => 'nameRole',
))
->add('update', SubmitType::class);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => null
));
}
}
我终于找到了，我只是从TWIG模板中删除了条件，它工作得很好，我有我想要的，它需要在哪里!
我把解决这个问题的最终代码贴在这里:
模板:
{% extends 'admin/base.admin.html.twig' %}
{% block body %}
<section class="container">
{{ user.pseudo }} |
{% set formChil = form.roles.children %}
{{ form_start(form) }}
{% for role in formChil %}
{% if role.vars.value in user.roles %}
{{ form_row(role, {'attr' : {'checked':true}}) }}
{% else %}
{{ form_row(role, {'attr' : {'checked':false}}) }}
{% endif %}
{% endfor %}
{{ form_end(form) }}
</section>
{% endblock %}
表单代码:
<?php
namespace AppBundle'Form;
use AppBundle'Entity'MembersEntity;
use AppBundle'Entity'RoleEntity;
use Symfony'Bridge'Doctrine'Form'Type'EntityType;
use Symfony'Component'Form'AbstractType;
use Symfony'Component'Form'Extension'Core'Type'SubmitType;
use Symfony'Component'Form'FormBuilderInterface;
use Symfony'Component'OptionsResolver'OptionsResolver;
class ChangeRoleForm extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('roles', EntityType::class, array(
'class' => RoleEntity::class,
'choice_label' => 'nameRole',
'multiple' => true,
'expanded' => true,
'choice_value' => 'nameRole',
))
->add('update', SubmitType::class);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => null
));
}
}
这里是调用模板的方法，以及表单构造:
<?php
public function editMemberAction($id, Request $request)
{
$em = $this->getDoctrine()->getManager();
$user = $this->getDoctrine()->getRepository(MembersEntity::class)->find($id);
$form = $this->createForm(ChangeRoleForm::class, $user, array('method' => 'PUT'));
if($request->isMethod('PUT'))
{
$form->handleRequest($request);
$roles = $form->get('roles')->getData();
$data = array();
foreach($roles as $role)
{
$data[] = $role->getNameRole();
}
$user->setRoles($data);
$em->persist($user);
$em->flush();
}
return $this->render('admin/edit-role-member.html.twig', ['form' => $form->createView(), 'user' => $user]);
}
