specific price calculations


Recommended Posts

Hi all, Hope this is the correct place for this query.


Can anyone point me in the right direction to find where Prestashop uses the specific_price so I can reverse the percentage reduction.


I need to increase prices for one country by 44% for all combinations and all products. I have purchased Geo Targeting Pro

which detects the country ok but specific prices can only reduce by a percentage or use a fixed price. The specific price enters in the DB a reduction 0.44 but where is the maths being done?


I did find in public_html/classes/Product.php this section but dont know if this uses the reduction and if it does how to use the 0.44 as an increase.

// Reduction
		$specific_price_reduction = 0;
		if (($only_reduc || $use_reduc) && $specific_price)
			if ($specific_price['reduction_type'] == 'amount')
				$reduction_amount = $specific_price['reduction'];

				if (!$specific_price['id_currency'])
					$reduction_amount = Tools::convertPrice($reduction_amount, $id_currency);

				if (!isset($specific_price['reduction_tax']) || (isset($specific_price['reduction_tax']) && $specific_price['reduction_tax']))
					$specific_price_reduction = !$use_tax ? $product_tax_calculator->removeTaxes($reduction_amount) : $reduction_amount;
					$specific_price_reduction = $reduction_amount;
				$specific_price_reduction = $price * $specific_price['reduction'];

		if ($use_reduc)
			$price -= $specific_price_reduction;
		// Group reduction
		if ($use_group_reduction)
			$reduction_from_category = GroupReduction::getValueForProduct($id_product, $id_group);
			if ($reduction_from_category !== false)
				$group_reduction = $price * (float)$reduction_from_category;
			else // apply group reduction if there is no group reduction for this category
				$group_reduction = (($reduc = Group::getReductionByIdGroup($id_group)) != 0) ? ($price * $reduc / 100) : 0;
			$group_reduction = 0;

		if ($only_reduc)
			return Tools::ps_round($group_reduction + $specific_price_reduction, $decimals);

		if ($use_reduc)
			$price -= $group_reduction;
