FormTypeExtensionInterface::buildForm()

buildView(FormView $view, FormInterface $form, array $options)

Builds the form view.

This method is called for each type in the hierarchy starting form the top most type. Type extensions can further modify the view.

A view of a form is built before the views of the child forms are built. This means that you cannot access child views in this method. If you need to do so, move your logic to {@link finishView()} instead.

Parameters

FormView	$view	The view
FormInterface	$form	The form
array	$options	The options

FormTypeExtensionInterface::buildView()

finishView(FormView $view, FormInterface $form, array $options)

Finishes the form view.

This method gets called for each type in the hierarchy starting form the top most type. Type extensions can further modify the view.

When this method is called, views of the form's children have already been built and finished and can be accessed. You should only implement such logic in this method that actually accesses child views. For everything else you are recommended to implement {@link buildView()} instead.

Parameters

FormView	$view	The view
FormInterface	$form	The form
array	$options	The options

The name of the parent type if any, null otherwise.

string getName()

Returns the name of this type.

Return Value

string

The name of this type
