I'm new here. I've got an issue with adding to the custom theme in PrestaShop 1.7 a new product flag which is Bestselling.
I've found that in ProductLazyArray.php are definitions for those flags, but this file is a core file and I'm not sure that I should modify that.
Can you help me with that one? Thank you in advance!
thanks for replying. I've figured that one out by adding hook into ProductLazyArray.php. It goes like:
\Hook::exec('actionProductFlagsModifier', array (
'flags' => & $flags,
'product' => $this-> product,
));
And my module logic is like:
public function getBestSellingProductsId() {
$bestSellingProducts = ProductSale::getBestSalesLight((int)$this->langID, 0);
$productsIdArray = array();
foreach ($bestSellingProducts as $bestSellingProduct) {
if (!empty($bestSellingProducts) && !in_array($bestSellingProduct['id_product'], $productsIdArray)) {
$productsIdArray[] = $bestSellingProduct['id_product'];
}
}
return $productsIdArray;
}
public function isBestSelling($arrayOfBestSellingIds = array(), $productId) {
if (!empty($arrayOfBestSellingIds)) {
if (in_array($productId, $arrayOfBestSellingIds)) {
return true;
} else {
return false;
}
} else {
return false;
}
}
public function hookActionProductFlagsModifier($params)
{
$bestSellings = $this->getBestSellingProductsId();
$allProductsId = $params['product']['id_product'];
if (!empty($allProductsId)) {
if (in_array($allProductsId, $bestSellings)) {
array_push($params['product'], $params['product']['is_best_seller'] = (int) in_array($allProductsId, $bestSellings));
}
}
if (in_array('is_best_seller', $params['product'])
&& $this->isBestSelling($bestSellings, $allProductsId)) {
$params['flags']['bestseller'] = array(
'type' => 'bestseller',
'label' => 'Hit'
);
}
return $params;
}
