forms - isvalid - Cómo combinar 2 formularios en Symfony2

symfony form validation

Question

Intento crear un foro muy simple con Symfony2.

Mis entidades son: ForumCategory (nombre, descripción ...) ForumTopic (category_id, title) ForumPost (isFirstPost, body, topic_id, author_id ...)

Cuando un usuario intenta crear un tema, quiero mostrar solo un formulario en la misma página para crear un tema y el primer mensaje de la publicación. Me gusta:

• Insertar título del tema: ...
• Insertar cuerpo del tema (cuerpo del mensaje relacionado): ...

[...]

¿Cómo puedo hacer eso? ¿Es posible fusionar dos formularios en este caso?

Answer 1

Haga un tipo de formulario que contenga ambas formas secundarias.

class MergedFormType
$builder->add(''topic'', new TopicFormType());
$builder->add(''post'', new PostFormType());

En su controlador simplemente pase una matriz a MergedFormType

public function myAction()
$formData[''topic''] = $topic;
$formData[''post''] = $post;
$form = $this->createForm(new MergedFormType(), $formData);

Answer 2

En caso de que busque fusionar formularios para 2 entidades con una relación uno a muchos o uno a uno; Deberá usar la extensión de colección de formularios del componente Symfony 2. por ejemplo: donde la entidad Task tiene muchas etiquetas

class TaskType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add(''description'');
$builder->add(''tags'', ''collection'', array(''type'' => new TagType()));
}

La representación se puede hacer de esta manera

{{ form_start(form) }}
<h3>Tags</h3>
<ul class="tags">
{# iterate over each existing tag and render its only field: name #}
{% for tag in form.tags %}
<li>{{ form_row(tag.name) }}</li>
{% endfor %}
</ul>

Answer 3

También puede asignar la misma entidad a múltiples formularios combinados.

 $entity = new Form();
$form = $this->get(''form.factory'')->create(FormType::class, [
''form_builder'' => $entity,
''submit_builder'' => $entity,
]);
