我在 symfony2 中有 3 种表单类型
FaultType 是所有下一个集合的父级
<?php
namespace My\FaultBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
class FaultType extends AbstractType
{
public function buildForm(FormBuilder $builder, array $options)
{
$builder
->add('title')
->add('steps', 'collection', array(
'type' => new StepType(),
'allow_add' => true,
'prototype' => true,
'by_reference' => false,
))
->add('created')
->add('updated')
;
}
public function getDefaultOptions()
{
return array(
'data_class' => 'My\FaultBundle\Entity\Fault'
);
}
public function getName()
{
return 'my_fault_fault';
}
}
步骤类型:
<?php
namespace My\FaultBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
class StepType extends AbstractType
{
public function buildForm(FormBuilder $builder, array $options)
{
$builder
->add('body')
->add('photos', 'collection', array(
'type' => new PhotoType(),
'allow_add' => true,
'allow_delete' => true,
'prototype' => true,
'by_reference' => false,
))
;
}
public function getDefaultOptions()
{
return array(
'data_class' => 'My\FaultBundle\Entity\Step'
);
}
public function getName()
{
return 'my_fault_step';
}
}
和最后一个 PhotoType:
<?php
namespace My\FaultBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
class PhotoType extends AbstractType
{
public function buildForm(FormBuilder $builder, array $options)
{
$builder
->add('name')
->add('description')
->add('filename')
;
}
public function getDefaultOptions()
{
return array(
'data_class' => 'My\FaultBundle\Entity\Photo'
);
}
public function getName()
{
return 'my_fault_photo';
}
}
我发现关于原型的优秀文章链接,并且使用一个嵌套表单类型非常好,但是当我想让它与第三个嵌套意味着 PhotoType 一起工作时我遇到了问题......照片在步骤的集合中,这是集合错误...,如何通过此示例为步骤动态添加/删除照片...?
