ElementInfoManager::getInfo

public ElementInfoManager::getInfo($type)

Retrieves the default properties for the defined element type.

Each of the form element types defined by this hook is assumed to have a matching theme hook, which should be registered with hook_theme() as normal.

For more information about custom element types see the explanation at https://www.drupal.org/node/169815.

Parameters

string $type: The machine name of an element type plugin.

Return value

• #input: boolean indicating whether or not this element carries a value (even if it's hidden).
• #process: array of callback functions taking $element, $form_state, and $complete_form.
• #after_build: array of callables taking $element and $form_state.
• #validate: array of callback functions taking $form and $form_state.
• #element_validate: array of callback functions taking $element and $form_state.
• #pre_render: array of callables taking $element.
• #post_render: array of callables taking $children and $element.
• #submit: array of callback functions taking $form and $form_state.
