shop:onExtendCategoryModel event

This event allows you to define new fields in the product category model. The event handler should accept two parameters - the category object (Shop_Category) and the form execution context string. To add new columns to the category model, please call the define_column() method of the category object. Before you add new columns to the model, you should add them to the database (the shop_categories table). Please read the Extending existing models article to learn more about extending existing LemonStand models.

Example of the event handler:

public function subscribeEvents()
{
   Backend::$events->addEvent('shop:onExtendCategoryModel', $this, 'extend_category_model');
   Backend::$events->addEvent('shop:onExtendCategoryForm', $this, 'extend_category_form');
}

public function extend_category_model($category, $context)
{
   $category->define_column('x_extra_description', 'Extra description');
}

public function extend_category_form($category, $context)
{
   $category->add_form_field('x_extra_description')->tab('Category');
}
