Question

我很想为某些领域写一个包。现在我得到了一个我可以延伸的课程。班上有一些领域，例如标题，名称等。

现在我想写一个formType，可以用另一种formtype扩展。

喜欢

class newsgroupType extends AbstractType
{
/**
 * @param FormBuilderInterface $builder
 * @param array $options
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('unusername','text',array(
                'required' => true))
        ->add('unactive','checkbox',array(
                'required' => false));
...

我想要扩展的FormType是

class mainType extends AbstractType
{
/**
 * @param FormBuilderInterface $builder
 * @param array $options
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('unurl','text',array(
              'required' => false,
              'disabled' => true))
        ->add('untitle','text',array(
              'required' => false))
...

有没有办法扩展mainType以将其中的所有字段都放入我的newsgroupType？

非常感谢=）

Answer 1

There is a cookbook article on the Symfony website that gives and example of how to extract common fields into a separate form definition which can then be included into other form definitions.

Create a separate Form class that includes the common fields using the builder. You can then configure that form using the inherit_data option:

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'inherit_data' => true
    ));
}

The other forms can then add that form in the builder:

public function buildForm(FormBuilderInterface $builder, array $options)
{
    // ...

    $builder->add('foo', new CommonType(), array(
        'data_class' => 'AppBundle\Entity\Foo'
    ));
}

I think you should think it differently.

You can use nested form types to do what you want.

For example :

class newsgroupType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('main', new MainType())
            ->add('unusername','text',array(
                    'required' => true))
            ->add('unactive','checkbox',array(
                    'required' => false));
...

You should also namle your classes the right way, with CamelCase (in my example, MainType instead of mainType)
