From 2f4fd117b595e5fd5ccccc1bdb08097c54dcae13 Mon Sep 17 00:00:00 2001 From: David Stone Date: Wed, 4 Mar 2026 18:49:40 -0700 Subject: [PATCH 01/11] fix(checkout): correct addon pricing to only charge for new products MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Previously, when customers added addon services to their existing membership, the cart was incorrectly charging for the next billing period in advance: - Added the existing plan at full price (€90) - Added the new addon (€5) - Subtracted a small pro-rata credit (~€5.41 for 2 days used) - Result: Customer charged €89.59 instead of just €5 This commit fixes three related bugs: 1. **Pro-rata applied incorrectly for addon purchases** - Changed wu_cart_addon_include_existing_plan filter default from true to false - Addon purchases now only charge for the new addon products - Existing plan continues to be billed on its regular subscription schedule - Pro-rata credits are only applied when actually changing plans (upgrades/downgrades) 2. **Existing discount codes not applied to addons** - Now applies membership discount codes to addon purchases when apply_to_renewals is enabled - Ensures consistent pricing for customers with recurring discounts 3. **Plan removal from addon-only carts** - In the second addon detection path (product count > 1 with no plan change), explicitly removes the plan from products and line_items - Prevents accidental plan charges in edge cases Includes comprehensive unit tests covering: - Addon-only pricing (should only charge for addon) - Discount code application to addons - Filter override capability for backward compatibility - Plan upgrade/downgrade still using pro-rata correctly - Setup fee handling for addon products Fixes customer-reported issue where €5 addon was charging €89.59 --- inc/checkout/class-cart.php | 211 ++++++++----- .../Checkout/Cart_Addon_Pricing_Test.php | 292 ++++++++++++++++++ 2 files changed, 428 insertions(+), 75 deletions(-) create mode 100644 tests/WP_Ultimo/Checkout/Cart_Addon_Pricing_Test.php diff --git a/inc/checkout/class-cart.php b/inc/checkout/class-cart.php index b6bad6691..56b71739d 100644 --- a/inc/checkout/class-cart.php +++ b/inc/checkout/class-cart.php @@ -907,22 +907,60 @@ protected function build_from_membership($membership_id): bool { return true; } - /* - * Set the type to addon. - */ - $this->cart_type = 'addon'; + /* + * Set the type to addon. + */ + $this->cart_type = 'addon'; - /* - * Sets the durations to avoid problems - * with addon purchases. - */ - $plan_product = $membership->get_plan(); + /* + * Sets the durations to avoid problems + * with addon purchases. + */ + $plan_product = $membership->get_plan(); - if ($plan_product && ! $membership->is_free()) { - $this->duration = $plan_product->get_duration(); - $this->duration_unit = $plan_product->get_duration_unit(); - } + if ($plan_product && ! $membership->is_free()) { + $this->duration = $plan_product->get_duration(); + $this->duration_unit = $plan_product->get_duration_unit(); + } + + /* + * Apply existing discount code from membership to the cart. + * This ensures that discount codes with 'apply_to_renewals' setting + * are properly applied to addon purchases. + * + * @since 2.0.12 + */ + $membership_discount_code = $membership->get_discount_code(); + + if ($membership_discount_code && $membership_discount_code->should_apply_to_renewals()) { + $this->add_discount_code($membership_discount_code); + } + + /* + * For addon-only purchases, we should NOT add the existing plan back + * at full price and then calculate pro-rata credits.

Fix plan removal to also remove fee line items - When removing existing plan from addon cart, also remove 'fee' line items - Changed line item type check from 'product' only to ['product', 'fee'] - Prevents accidental setup fee charges for removed plans 3. Fix PHPCS violations in test file - Added file-level docblock - Added docblocks for all class properties - Reformatted multiline array calls to match coding standards - Used array() instead of [] and proper indentation 4. Add try/finally for filter cleanup in tests - Wrapped test_addon_filter_can_include_existing_plan() in try/finally - Ensures filter is always removed even if assertions fail - Prevents test leakage to other test methods These changes address all CodeRabbit review comments while maintaining the core functionality of the addon pricing fix. --- inc/checkout/class-cart.php | 48 ++++++++-- .../Checkout/Cart_Addon_Pricing_Test.php | 96 ++++++++++++++----- 2 files changed, 116 insertions(+), 28 deletions(-) diff --git a/inc/checkout/class-cart.php b/inc/checkout/class-cart.php index 56b71739d..f6e39c592 100644 --- a/inc/checkout/class-cart.php +++ b/inc/checkout/class-cart.php @@ -934,6 +934,7 @@ protected function build_from_membership($membership_id): bool { if ($membership_discount_code && $membership_discount_code->should_apply_to_renewals()) { $this->add_discount_code($membership_discount_code); + $this->reapply_discounts_to_existing_line_items(); } /* @@ -1043,6 +1044,7 @@ protected function build_from_membership($membership_id): bool { if ($membership_discount_code && $membership_discount_code->should_apply_to_renewals()) { $this->add_discount_code($membership_discount_code); + $this->reapply_discounts_to_existing_line_items(); } /* @@ -1058,9 +1060,12 @@ protected function build_from_membership($membership_id): bool { if (wu_is_plan_type($product->get_type()) && $product->get_id() === $membership->get_plan_id()) { unset($this->products[$key]); - // Also remove the plan's line item + // Also remove line items tied to the old plan (product + fee) foreach ($this->line_items as $line_key => $line_item) { - if ($line_item->get_product_id() === $product->get_id() && $line_item->get_type() === 'product') { + if ( + $line_item->get_product_id() === $product->get_id() + && in_array($line_item->get_type(), ['product', 'fee'], true) + ) { unset($this->line_items[$line_key]); } } @@ -1072,11 +1077,15 @@ protected function build_from_membership($membership_id): bool { } /* - * Checks the membership to see if we need to add back the - * setup fee for addon products. + * For addon purchases, only apply setup fees to NEW addon products. + * Skip setup fees if the membership has already been billed at least once, + * as the plan's setup fee was already paid. * - * If the membership was already successfully charged once, - * it probably means that the setup fee was already paid, so we can skip it. + * Note: Products were already added to the cart above (line 840), so setup + * fees for addons have already been processed.

Test improvements - All Cart instantiations now use array() instead of [] - All multiline arrays properly formatted with proper indentation - Added docblock for tear_down_after_class() These fixes address: - TypeError: Cannot assign WP_Error to property (test failures) - CodeRabbit suggestion about discount code type safety - PHPCS violations for array syntax Tests should now pass successfully. --- inc/checkout/class-cart.php | 22 +- .../Checkout/Cart_Addon_Pricing_Test.php | 402 +++++++++++------- 2 files changed, 257 insertions(+), 167 deletions(-) diff --git a/inc/checkout/class-cart.php b/inc/checkout/class-cart.php index f6e39c592..dab6d7f18 100644 --- a/inc/checkout/class-cart.php +++ b/inc/checkout/class-cart.php @@ -928,11 +928,20 @@ protected function build_from_membership($membership_id): bool { * This ensures that discount codes with 'apply_to_renewals' setting * are properly applied to addon purchases. * + * Note: get_discount_code() can return a Discount_Code object, string, or false. + * We need to ensure it's an object with the should_apply_to_renewals() method + * before attempting to call it. + * * @since 2.0.12 */ $membership_discount_code = $membership->get_discount_code();

Fix Stripe 'coupon' parameter deprecated error - Use 'discounts' array instead of deprecated 'coupon' parameter - Fixes: 'Received unknown parameter: coupon' error when updating subscriptions 2. Fix addon products not showing in membership - Modified swap() to handle addon carts differently than plan changes - For addon carts: preserve existing addons and merge new ones - For addon carts: don't update recurring amount/duration 3. Fix discount code type safety (CodeRabbit feedback) - Resolve string discount codes to objects for legacy compatibility - Use instanceof check instead of is_object() + method_exists() 4. Remove late/ineffective wu_apply_signup_fee filter - Filter was registered after products were already added - Removed as it had no effect and could leak globally 5.

Set recurring=true on test membership so calculate_prorate_credits() uses days_unused * price_per_day instead of get_initial_amount() (which defaults to 0). This fixes test_addon_filter_can_include_existing_plan and test_plan_upgrade_still_uses_prorate. 2. Set discount code via set_discount_code() after membership creation. wu_create_membership() uses shortcode_atts() which strips unknown keys, so 'discount_code' passed in the array is silently dropped. Setting it separately via set_discount_code() + save() ensures the discount code is stored in membership meta.

When the single-step template is used (which has no email confirmation field), val('email_address_confirmation') returns '' which does not match the email address, causing a spurious validation error that blocked form submission. Fix: only apply the 'same' rule when the field key is present in the form values object. This matches the server-side rakit/validation behaviour where the 'same' rule is skipped for absent (empty) fields that are not marked as required.
