ulgm_apply_bulk_discount_on_fixed_price

Description

Usage

add_filter( 'ulgm_apply_bulk_discount_on_fixed_price', 'your_function_name', 10, 1 );

Parameters

$_product (mixed)

This parameter is a boolean that, when set to `true`, forces the bulk discount to be applied to the product.

Return Value

The filtered value.

Examples

/**
 * Example filter to conditionally disable bulk discounts on products with a fixed license price.
 *
 * In this example, we assume that if a product has a fixed license price set,
 * we might want to prevent standard bulk discounts from applying to it, perhaps
 * to ensure the fixed license price remains the primary pricing mechanism.
 *
 * @param bool $_product_id The product ID being processed.
 * @param WC_Product $_product The WooCommerce product object.
 * @return bool True to allow bulk discount, false to prevent it.
 */
add_filter( 'ulgm_apply_bulk_discount_on_fixed_price', function( $allow_discount, $_product ) {

	// Check if the product is an instance of WC_Product
	if ( ! $_product instanceof WC_Product ) {
		return $allow_discount; // Return original value if not a valid product
	}

	// Get the product ID
	$product_id = $_product->get_id();

	// If this is a product where a fixed license price is set,
	// and we want to prevent bulk discounts on such items, return false.
	// This assumes a function like 'is_fixed_license_price_product' exists
	// to determine if a product has a fixed license price.
	if ( function_exists( 'is_fixed_license_price_product' ) && is_fixed_license_price_product( $product_id ) ) {
		// We're explicitly preventing the bulk discount for fixed license price products.
		return false;
	}

	// Otherwise, allow the default behavior for applying bulk discounts.
	return $allow_discount;

}, 10, 2 ); // Priority 10, accepts 2 arguments
