Overview of the issue

In WooCommerce Subscriptions, when updating a subscription (whether it’s an upgrade, downgrade, or crossgrade), the price isn’t filtered correctly. This results in incorrect pricing during the change of subscription plans.

Workaround

Please, make sure of having a full backup of your site before proceeding.


  • Open …/wp-content/plugins/woocommerce-multilingual/compatibility/WcSubscriptions/MulticurrencyHooks.php file.

  • Look for line 253.

  • Change: 
    	public function woocommerce_subscription_price_from( $price, $product ) {
		if ( $product instanceof WC_Product_Subscription_Variation ) {
			$customPricesOn = get_post_meta( $product->get_id(), '_wcml_custom_prices_status', true );

			if ( $customPricesOn ) {
				$price = get_post_meta( $product->get_id(), '_price_' . $this->woocommerce_wpml->multi_currency->get_client_currency(), true );
			} else {
				$price = apply_filters( 'wcml_raw_price_amount', $price );
			}
		}

		return $price;
	}

  • For: 
    	public function woocommerce_subscription_price_from( $price, $product ) {
		if ( $product instanceof WC_Product_Subscription_Variation || $product instanceof \WC_Product_Subscription) {
			$customPricesOn = get_post_meta( $product->get_id(), '_wcml_custom_prices_status', true );

			if ( $customPricesOn ) {
				$price = get_post_meta( $product->get_id(), '_price_' . $this->woocommerce_wpml->multi_currency->get_client_currency(), true );
			} else {
                $id = $product->get_id();
                $type = get_post_type($id);
				$trid = apply_filters( 'wpml_element_trid', NULL, $id,  'post_'.$type );
				$translations = apply_filters( 'wpml_get_element_translations', NULL, $trid , 'post_'.$type );
                foreach ($translations as $translation){
                    if ($translation->original == 1){
                        if ( get_post_meta( $translation->element_id, '_wcml_custom_prices_status', true ) ) {
	                        $price = get_post_meta( $translation->element_id, '_price_' . $this->woocommerce_wpml->multi_currency->get_client_currency(), true );
                        } else {
	                        $price = apply_filters( 'wcml_raw_price_amount', $price );
                        }
                    }
                }
            }
		}

		return (int)$price;
	}
