Question

根据Symfony docs，可以自定义单个收集表单类型。如何让Symfony检测我的自定义树枝模板？似乎开箱即用，但是我可能错过了一些东西。

src \ Form \ Type \ ItemAliasType：

class ItemAliasType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add("name", TextType::class, [
            "label"              => "item alias name",
            "required"           => true,
        ]);

        $builder->add("description", TextType::class, [
            "label"              => "item alias name",
            "required"           => true,
        ]);
    }

    /**
     * {@inheritdoc}
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => ItemAlias::class,
        ]);
    }
}

src / Form / ItemForm：

class ItemForm extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        /* ... code ... */

        $builder->add("aliases", CollectionType::class, array_merge([
            "label"              => "item-aliases",
            "entry_type"         => ItemAliasType::class,
            "allow_add"          => true,
            "allow_delete"       => true,
            "prototype"          => true,
        ], $inheritedOptions));

    }
}

templates / form / collections.html.twig：

{% block _aliases_entry_row %}
    <div class="custom">
        {{ form_widget(form.name) }}
        {{ form_widget(form.description) }}
    </div>
{% endblock %}

config / packages / twig.yaml：

twig:
    form_theme:
        - 'form/collections.html.twig'

Answer 1

树枝模板中的块应使用不同的名称

templates / form / collections.html.twig：

{% block _item_form_aliases_entry_row %}

要阻止的标识符应为<form_name><form_child_name>_entry_(row|widget|label)
