cms:onExtendPageForm event
This event allows to add new fields to the Create/Edit Page form in the Administration Area. Usually this event is used together with the cms:onExtendPageModel event. The event handler should accept two parameters - the page object (Cms_Page) and the form execution context string. To add new fields to the page form, please call the add_form_field() method of the page object. Please read the Extending existing models article to learn more about extending LemonStand models.
Example of the event handler:
public function subscribeEvents()
{
Backend::$events->addEvent('cms:onExtendPageModel', $this, 'extend_page_model');
Backend::$events->addEvent('cms:onExtendPageForm', $this, 'extend_page_form');
}
public function extend_page_model($page, $context)
{
$page->define_column('x_extra_description', 'Extra description');
}
public function extend_page_form($page, $context)
{
if ($context != 'content')
$page->add_form_field('x_extra_description')->tab('Description');
}
Next: shop:onGetCustomerFieldOptions event
Previous: cms:onBeforeDisplay event
