[Решено] SQL запрос для получения товаров из категории

[mashkovtsevlx]

Здравствуйте. Необходимо вытащить все товары из определенной категории для модуля. 

 

Вот код из модуля. Вытягивает товары с акциями.

if( isset($setting['tabs']['special']) ){

$products = $this->getProducts( $this->model_catalog_product->getProductSpecials( $data ), $setting );

$this->data['heading_title'] = $this->language->get('text_special');

}

Код функции для получения товаров с акциями

public function getProductSpecials($data = array()) {

if ($this->customer->isLogged()) {

$customer_group_id = $this->customer->getCustomerGroupId();

} else {

$customer_group_id = $this->config->get('config_customer_group_id');

}

 

$sql = "SELECT DISTINCT ps.product_id, (SELECT AVG(rating) FROM " . DB_PREFIX . "review r1 WHERE r1.product_id = ps.product_id AND r1.status = '1' GROUP BY r1.product_id) AS rating FROM " . DB_PREFIX . "product_special ps LEFT JOIN " . DB_PREFIX . "product p ON (ps.product_id = p.product_id) LEFT JOIN " . DB_PREFIX . "product_description pd ON (p.product_id = pd.product_id) LEFT JOIN " . DB_PREFIX . "product_to_store p2s ON (p.product_id = p2s.product_id) WHERE p.status = '1' AND p.date_available <= NOW() AND p2s.store_id = '" . (int)$this->config->get('config_store_id') . "' AND ps.customer_group_id = '" . (int)$customer_group_id . "' AND ((ps.date_start = '0000-00-00' OR ps.date_start < NOW()) AND (ps.date_end = '0000-00-00' OR ps.date_end > NOW())) GROUP BY ps.product_id";

 

$sort_data = array(

'pd.name',

'p.model',

'ps.price',

'rating',

'p.sort_order'

);

 

if (isset($data['sort']) && in_array($data['sort'], $sort_data)) {

if ($data['sort'] == 'pd.name' || $data['sort'] == 'p.model') {

$sql .= " ORDER BY LCASE(" . $data['sort'] . ")";

} else {

$sql .= " ORDER BY " . $data['sort'];

}

} else {

$sql .= " ORDER BY p.sort_order";

}

 

if (isset($data['order']) && ($data['order'] == 'DESC')) {

$sql .= " DESC, LCASE(pd.name) DESC";

} else {

$sql .= " ASC, LCASE(pd.name) ASC";

}

 

if (isset($data['start']) || isset($data['limit'])) {

if ($data['start'] < 0) {

$data['start'] = 0;

}

 

if ($data['limit'] < 1) {

$data['limit'] = 20;

}

 

$sql .= " LIMIT " . (int)$data['start'] . "," . (int)$data['limit'];

}

 

$product_data = array();

 

$query = $this->db->query($sql);

 

foreach ($query->rows as $result) {

$product_data[$result['product_id']] = $this->getProduct($result['product_id']);

}

 

return $product_data;

}

 

Необходимо преобразовать код для получения товаров с акциями в код для получения товаров из определенной категории. Код модуля понимаю, но не функции, которая вытягивает товары. Кто поможет, как надо преобразить? Просто заточить под вытягивание из категории с определенным id

[halfhope]

model_product_product

$this->data['products'] = array();

$data = array(
	'filter_category_id' => $category_id,
	'filter_filter'      => $filter, 
	'sort'               => $sort,
	'order'              => $order,
	'start'              => ($page - 1) * $limit,
	'limit'              => $limit
);
		
$results = $this->model_catalog_product->getProducts($data);
//Вызов метода getFoundProducts должен проводится сразу же после getProducts
//только тогда он выдает правильное значения количества товаров
$product_total = $this->model_catalog_product->getFoundProducts(); 

Выдерните код из категорий

 

UPD: Прошу прощения, не то написал.

 

Вот рабочий SQL код, там добавлен "left join oc_product_to_category p2c ON (p2c.product_id = ps.product_id)" WHERE "p2c.category_id = $data['category_id'] AND".

SELECT DISTINCT ps.product_id, (

SELECT AVG( rating ) 
FROM oc_review r1
WHERE r1.product_id = ps.product_id
AND r1.status =  '1'
GROUP BY r1.product_id
) AS rating
FROM oc_product_special ps
LEFT JOIN oc_product p ON ( ps.product_id = p.product_id ) 
LEFT JOIN oc_product_description pd ON ( p.product_id = pd.product_id ) 
LEFT JOIN oc_product_to_store p2s ON ( p.product_id = p2s.product_id ) 
LEFT JOIN oc_product_to_category p2c ON ( p2c.product_id = ps.product_id ) 
WHERE p2c.category_id =20
AND p.status =  '1'
AND p.date_available <= NOW( ) 
AND p2s.store_id =  '0'
AND ps.customer_group_id =  '1'
AND (
(
ps.date_start =  '0000-00-00'
OR ps.date_start < NOW( )
)
AND (
ps.date_end =  '0000-00-00'
OR ps.date_end > NOW( )
)
)
GROUP BY ps.product_id
ORDER BY LCASE( pd.name ) ASC , LCASE( pd.name ) ASC 
LIMIT 0 , 5

 

Вот готовый PHP:

$sql = "SELECT DISTINCT ps.product_id, (SELECT AVG(rating) FROM " . DB_PREFIX . "review r1 WHERE r1.product_id = ps.product_id AND r1.status = '1' GROUP BY r1.product_id) AS rating FROM " . DB_PREFIX . "product_special ps LEFT JOIN " . DB_PREFIX . "product p ON (ps.product_id = p.product_id) LEFT JOIN " . DB_PREFIX . "product_description pd ON (p.product_id = pd.product_id) LEFT JOIN " . DB_PREFIX . "product_to_store p2s ON (p.product_id = p2s.product_id) LEFT JOIN ".DB_PREFIX."product_to_category p2c ON (p2c.product_id = ps.product_id) WHERE p2c.category_id = '" . (int)$data['category_id'] . "' AND p.status = '1' AND p.date_available <= NOW() AND p2s.store_id = '" . (int)$this->config->get('config_store_id') . "' AND ps.customer_group_id = '" . (int)$customer_group_id . "' AND ((ps.date_start = '0000-00-00' OR ps.date_start < NOW()) AND (ps.date_end = '0000-00-00' OR ps.date_end > NOW())) GROUP BY ps.product_id";
 

 

Когда вставите, то передавайте в функцию getProductSpecials() массив $data, в котором $data['category_id'] = $category_id

Разобрался сам, но все же спасибо большое!
