Я хочу получить новые продукты из категории, поэтому я попытался сменить контроллер.
В prestashop 1.7 есть NewProductsController.php,
А внутри есть эта функция
protected function getProductSearchQuery()
{
$query = new ProductSearchQuery();
$query
->setQueryType('new-products')
->setSortOrder(new SortOrder('product', 'date_add', 'desc'))
;
return $query;
}
И я изменил его на
protected function getProductSearchQuery()
{
$query = new ProductSearchQuery();
$query
->setIdCategory('MY-NEW-ID-CATEGORY')
->setQueryType('new-products')
->setSortOrder(new SortOrder('product', 'date_add', 'desc'))
;
return $query;
}
Но он по-прежнему показывает все продукты, а не продукты из этой категории.
Я решил использовать другой способ,
В Product.php я пишу
public static function getNewProductsFromCategory($id_lang, $page_number = 0, $nb_products = 10, $count = false, $order_by = null, $order_way = null, $category_id = 2, Context $context = null)
{
$now = date('Y-m-d') . ' 00:00:00';
if (!$context) {
$context = Context::getContext();
}
$front = true;
if (!in_array($context->controller->controller_type, array('front', 'modulefront'))) {
$front = false;
}
if ($page_number < 1) {
$page_number = 1;
}
if ($nb_products < 1) {
$nb_products = 10;
}
if (empty($order_by) || $order_by == 'position') {
$order_by = 'date_add';
}
if (empty($order_way)) {
$order_way = 'DESC';
}
if ($order_by == 'id_product' || $order_by == 'price' || $order_by == 'date_add' || $order_by == 'date_upd') {
$order_by_prefix = 'product_shop';
} elseif ($order_by == 'name') {
$order_by_prefix = 'pl';
}
if (!Validate::isOrderBy($order_by) || !Validate::isOrderWay($order_way)) {
die(Tools::displayError());
}
$sql_groups = '';
if (Group::isFeatureActive()) {
$groups = FrontController::getCurrentCustomerGroups();
$sql_groups = ' AND EXISTS(SELECT 1 FROM `'._DB_PREFIX_.'category_product` cp
JOIN `'._DB_PREFIX_.'category_group` cg ON (cp.id_category = cg.id_category AND cg.`id_group` '.(count($groups) ? 'IN ('.implode(',', $groups).')' : '= '.(int)Configuration::get('PS_UNIDENTIFIED_GROUP')).')
WHERE cp.`id_product` = p.`id_product`)';
}
if (strpos($order_by, '.') > 0) {
$order_by = explode('.', $order_by);
$order_by_prefix = $order_by[0];
$order_by = $order_by[1];
}
$nb_days_new_product = (int) Configuration::get('PS_NB_DAYS_NEW_PRODUCT');
if ($count) {
$sql = 'SELECT COUNT(p.`id_product`) AS nb

);
$sql->from('product', 'p');
$sql->join(Shop::addSqlAssociation('product', 'p'));
$sql->leftJoin('product_lang', 'pl', '

if (Group::isFeatureActive()) {

$sql->where('EXISTS(SELECT 1 FROM `'._DB_PREFIX_.'category_product` cp

WHERE cp.`id_product` = p.`id_product`)');
}
$sql->orderBy((isset($order_by_prefix) ? pSQL($order_by_prefix).'.' : '').'`'.pSQL($order_by).'` '.pSQL($order_way));
$sql->limit($nb_products, (int)(($page_number-1) * $nb_products));
if (Combination::isFeatureActive()) {
$sql->select('product_attribute_shop.minimal_quantity AS product_attribute_minimal_quantity, IFNULL(product_attribute_shop.id_product_attribute,0) id_product_attribute');
$sql->leftJoin('product_attribute_shop', 'product_attribute_shop', 'p.`id_product` = product_attribute_shop.`id_product` AND product_attribute_shop.`default_on` = 1 AND product_attribute_shop.id_shop='.(int)$context->shop->id);
}
$sql->join(Product::sqlStock('p', 0));
$result = Db::getInstance(_PS_USE_SQL_SLAVE_)->executeS($sql);
if (!$result) {
return false;
}
if ($order_by == 'price') {
Tools::orderbyPrice($result, $order_way);
}
$products_ids = array();
foreach ($result as $row) {
$products_ids[] = $row['id_product'];
}
// Thus you can avoid one query per product, because there will be only one query for all the products of the cart
Product::cacheFrontFeatures($products_ids, $id_lang);
return Product::getProductsProperties((int)$id_lang, $result);
}
И в моем контроллере я получаю идентификаторы продуктов из моей новой функции в контроллере продуктов, а затем получаю атрибуты продуктов
$products_id = Product::getNewProductsFromCategory($this->context->language->id,0, 1,false,'date_add', 'DESC',$category_ids);
$this->returnLastProductsFromCategory($products_id);
public function returnLastProductsFromCategory($products_id)
{
$products = Product::getProductsProperties($this->context->language->id, $products_id);
$assembler = new ProductAssembler($this->context);
$presenterFactory = new ProductPresenterFactory($this->context);
$presentationSettings = $presenterFactory->getPresentationSettings();
$presenter = new ProductListingPresenter(
new ImageRetriever(
$this->context->link
),
$this->context->link,
new PriceFormatter(),
new ProductColorsRetriever(),
$this->context->getTranslator()
);
$products_for_template = [];
foreach ($products as $rawProduct) {
$products_for_template[] = $presenter->present(
$presentationSettings,
$assembler->assembleProduct($rawProduct),
$this->context->language
);
}
return $this->context->smarty->assign('products', $products_for_template);
//return $this->context->smarty->fetch('module:cmsproducts/products.tpl');
}
Это работает, но я думаю, что слишком много операций по сравнению с NewProductsController.
