public array getProducts ( array $data = array() )

Метод позволяет получить список продуктов, наложив на выборку определенные фильтры ($data).
Список доступных фильтров:

Ключ	Тип	Описание	Пример значения
filter_category_id	int	ID категории	5
filter_sub_category	int	ID подкатегории	33
filter_filter	int	ID фильтра товаров (модуль фильтра товаров)	4224
filter_name	string	Полное или часть названия продукта (поиск в названии, модели, sku, upc, ean, jan, isbn, mpn)	Iphone
filter_tag	string	Тег продукта	Iphone
filter_description	string	Описание продукта	телефон
filter_manufacturer_id	int	ID производителя продукта	44
sort	string	Поле, по которому произойдет сортировка. Доступные поля: $sort_data = array( 'pd.name', 'p.model', 'p.quantity', 'p.price', 'rating', 'p.sort_order', 'p.date_added' );	pd.name
order	string	порядок сортировки (ASC или DESC)	ASC
start	int	С какой по счету записи начинать выборку	0
limit	int	Сколько записей выбирать	200
