We moved these functions to static class WDP_Functions (but legacy class WDP_Frontend can be used too).

adp_functions()->getGiftedCartProducts() just returns array of free items (added by our plugin) as [product_id_1=>qty_1, product_id_2=>qty_2,..]

adp_functions()->getActiveRulesForProduct($productId, $qty = 1, $useEmptyCart = false) adds passed product to existing cart (or empty cart) and returns array of applied rules.

add_filter( 'woocommerce_get_price_html', function ( $price, $product ) {
	if ( empty( $product ) or empty( WC()->customer ) ) {
		return $price;
	}
	$context = new \ADP\BaseVersion\Includes\Context();
	$rule    = null;
	foreach (
		adp_functions()->getActiveRulesForProduct( $product->get_id(), $qty = 50, $use_empty_cart = true ) as $loopRule
	) {
		// discount table only for 'SingleItem' rule
		if ( $loopRule instanceof \ADP\BaseVersion\Includes\Rule\Structures\SingleItemRule && $loopRule->getProductRangeAdjustmentHandler() ) {
			$rule = $loopRule;
			break;
		}
	}
	if ( ! $rule ) {
		return $price;
	}
	$handler = $rule->getProductRangeAdjustmentHandler();
	$ranges  = $handler->getRanges();
	$range   = array_pop( $ranges );
	if ( ! $range ) {
		return $price;
	}
	$priceProcessor = new \ADP\BaseVersion\Includes\Product\Processor( $context );
	$cartBuilder    = new \ADP\BaseVersion\Includes\Cart\CartBuilder( $context );
	$cart           = $cartBuilder->create( WC()->customer, WC()->session );
	$priceProcessor->withCart( $cart );
	$priceFunctions = new \ADP\BaseVersion\Includes\External\WC\PriceFunctions( $context );
	$processedProd = $priceProcessor->calculateProduct( $product, $range->getFrom() );
	return "From " . $priceFunctions->format( $priceFunctions->getProcProductPriceToDisplay( $processedProd ) );
}, PHP_INT_MAX, 2 );

add_filter( 'woocommerce_get_price_html', function ( $price, $product ) {

if ( empty( $product ) or empty( WC()->customer ) ) {

return $price;

}

$context = new \ADP\BaseVersion\Includes\Context();

$rule = null;

adp_functions()->getActiveRulesForProduct( $product->get_id(), $qty = 50, $use_empty_cart = true ) as $loopRule

) {

// discount table only for 'SingleItem' rule

if ( $loopRule instanceof \ADP\BaseVersion\Includes\Rule\Structures\SingleItemRule && $loopRule->getProductRangeAdjustmentHandler() ) {

}

}

$handler = $rule->getProductRangeAdjustmentHandler();

adp_functions()->calculateProduct($product, $qty, $useEmptyCart = true) allows you to calculate an object \ADP\BaseVersion\Includes\Product\ProcessedProductSimple
or an object \ADP\BaseVersion\Includes\Product\ProcessedVariableProduct.
And in the pro version it calculates an object \ADP\ProVersion\Includes\Product\ProcessedVariableProduct.

adp_functions()->getDiscountedProductsForCart($listOfProducts, $plain = false) allows you to calculate price for list of products. You can use the following parameters:

listOfProducts
array[][‘product_id’]
array[][‘qty’]
array[][‘cart_item_data’] Optional
$plain
true/false

The function has 2 different return schemas.

It sounds a bit confusing, but you can use this way to get list of products which should be added to pre-build cart to get discounts.

adp_functions()->getDiscountedProductsForCart( 
                    array( // products will be added to empty WC cart to check conditions
                        array( 'product_id' => 93, 'qty' => 1 ),
                        array( 'product_id' => 95, 'qty' => 1 ), // may add 2nd product 
                    ), 
                    true // TRUE - plain array ,  FALSE - split by rules
                );

adp_functions()->getDiscountedProductsForCart(

array( // products will be added to empty WC cart to check conditions

array( 'product_id' => 93, 'qty' => 1 ),

array( 'product_id' => 95, 'qty' => 1 ), // may add 2nd product

true // TRUE - plain array , FALSE - split by rules

);

adp_functions()->getDiscountedProductPrice($product, $qty, $useEmptyCart = true) allows you to calculate price for product. You can use the following parameters:

int|WC_product $product(product id or product object)
float $qty
bool $useEmptyCart

The function has 3 different return schemas which are depended on first provided parameter:

float|array|null
float for simple product
array is (min, max) range for variable
null if product is incorrect
