Is it possible to show in the crosselling module the products that customers who have also bought this product have bought, but not in the same order?
I've tried to update the code this way, but it's not working:
I've tried to get the id_customer of the orders, and then search for all the orders on that customers.
crosselling.php
$orders = Db::getInstance(_PS_USE_SQL_SLAVE_)->executeS('
SELECT o.id_order, o.id_customer
FROM '._DB_PREFIX_.'orders o
LEFT JOIN '._DB_PREFIX_.'order_detail od ON (od.id_order = o.id_order)
WHERE o.valid = 1 AND od.product_id = '.(int)$params['product']->id);
if (sizeof($orders))
{
$list = '';
$list_c = '';
foreach ($orders AS $order){
$list .= (int)$order['id_order'].',';
$list_c .= (int)$order['id_customer'].',';
}
$list = rtrim($list, ',');
$list_c = rtrim($list_c, ',');
$orders2 = Db::getInstance(_PS_USE_SQL_SLAVE_)->executeS('
SELECT o.id_order
FROM '._DB_PREFIX_.'orders o
WHERE o.valid = 1 AND o.id_customer IN ('.$list_c.')');
if (sizeof($orders2))
{
foreach ($orders AS $order){
$list .= (int)$order['id_order'].',';
}
}
$list = rtrim($list, ',');
$orderProducts = Db::getInstance(_PS_USE_SQL_SLAVE_)->executeS('
SELECT DISTINCT od.product_id, pl.name, pl.link_rewrite, p.reference, i.id_image, product_shop.show_price, cl.link_rewrite category, p.ean13
FROM '._DB_PREFIX_.'order_detail od
LEFT JOIN '._DB_PREFIX_.'product p ON (p.id_product = od.product_id)
'.Shop::addSqlAssociation('product', 'p').'
LEFT JOIN '._DB_PREFIX_.'product_lang pl ON (pl.id_product = od.product_id'.Shop::addSqlRestrictionOnLang('pl').')
LEFT JOIN '._DB_PREFIX_.'category_lang cl ON (cl.id_category = product_shop.id_category_default'.Shop::addSqlRestrictionOnLang('cl').')
LEFT JOIN '._DB_PREFIX_.'image i ON (i.id_product = od.product_id)
WHERE od.id_order IN ('.$list.')
AND pl.id_lang = '.(int)$this->context->language->id.'
AND cl.id_lang = '.(int)$this->context->language->id.'
AND od.product_id != '.(int)$params['product']->id.'
AND i.cover = 1
AND product_shop.active = 1
ORDER BY RAND()
LIMIT '.(int)Configuration::get('CROSSSELLING_NBR').'
');
Any ideas will be appreciated, thank you!!
