WC Backorder Split

2.3.1 – 2026-10-01

• Fix – Variable products now split correctly. Stock was read from the parent product, which has none when stock is managed per variation.
• Fix – Orders placed with the Checkout block are now split. The plugin did not run during block checkout.
• Fix – Raising a quantity in the cart before checkout no longer moves in-stock items into the backorder order or marks the whole order backordered without splitting it.
• Fix – An order where nothing was in stock now just changes status instead of leaving the original order empty.
• Enhancement – Errors are logged to WooCommerce > Status > Logs instead of the server’s PHP error log.
• Enhancement – WooCommerce 11.1.2 compatibility.

2.3.0 – 2026-08-22

• Feature – Asks for a review on the Dashboard once the plugin has been used, with a link that pre-selects a five-star rating. Shown only after three orders have been split, dismissed per user rather than for the whole site, and never shown again once dismissed.
• Fix – The deactivation feedback dialog no longer leaves its button stuck on “Processing” if the request fails; deactivation proceeds either way.
• Security – The backorder success notice no longer reveals whether an order id exists to users who cannot edit orders.
• Fix – Order links in the backorder notice and the linked-orders panel now work on stores using High-Performance Order Storage. They used the legacy post editor URL, which does not resolve once orders live in their own tables.
• Fix – The deactivation feedback dialog is translatable again. Its text passed a text domain to a function that ignores the argument, and the domain named a different plugin.
• Security – Escaped the deactivation dialog’s markup and its inline script.
• Enhancement – Declared compatibility with the Cart and Checkout blocks, verified against the order path WooCommerce’s Store API actually uses.
• Enhancement – Adopted the WPHEKA framework for the HPOS declaration and plugin bootstrapping.
• Enhancement – Requires PHP 8.1 and WordPress 6.5. WordPress 7.1 and WooCommerce 11.0.1 compatibility added.

2.2.0 – 2026-05-06

• Enhancement – Backorder order creation now suppresses WooCommerce emails to prevent duplicate new-order and processing notifications.
• Enhancement – Backorder order now inherits all standard order fields: currency, prices include tax, customer IP, user agent, transaction ID, date paid, date completed, and stock reduced flag.
• Enhancement – WooCommerce order attribution and VAT exemption meta fields are now copied to the backorder order.
• Enhancement – Line items are cloned (not re-added via add_product) preserving product variations, custom fields, and all item-level meta data.
• Enhancement – Per-unit prices are captured before any order mutation so discount-adjusted totals remain correct on both orders.
• Enhancement – _reduced_stock meta is now split proportionally between the original and backorder order items.
• Enhancement – Address indexes (_billing_address_index, _shipping_address_index) are now copied to the backorder order for correct address search results (HPOS-aware).
• Enhancement – Both orders are scheduled for WooCommerce Admin analytics re-import after a split so revenue reports stay accurate.
• Enhancement – Added wcbs_meta_fields_to_copy and wcbs_disable_emails_on_split filters for developer extensibility.
• Fix – Stock quantity 0 at cart time now correctly removes the item from the original order instead of leaving it duplicated across both orders.
• Fix – Removed erroneous add_item() call after in-place source item update that caused calculate_totals() to double-count the item.

2.1.0 – 2026-02-17

• Security – Fixed unsanitized $_SERVER[‘REQUEST_URI’] access in REST API detection.
• Enhancement – Added comprehensive order data copying: shipping methods, payment info, fees, coupons, and taxes.
• Enhancement – Added order relationship linking between parent order and backorder.
• Enhancement – Added order notes to both orders explaining the split operation.
• Enhancement – Added admin panel display showing linked orders in order details.
• Enhancement – Added developer hooks for extensibility (wcbs_before_split_order, wcbs_after_split_order, wcbs_backorder_created, wcbs_split_order_error).
• Enhancement – Added filter hooks for customization (wcbs_should_split_order, wcbs_backorder_items, wcbs_backorder_status).
• Enhancement – Improved item meta data copying during split to preserve product variations and custom data.
• Enhancement – Added comprehensive PHPDoc documentation with @since tags throughout codebase.
• Fix – Critical: Added protection against duplicate order splits on page reload.
• Fix – Fixed fatal error “Call to a member function save() on int” when copying item meta data.
• Fix – Fixed order splitting logic to work correctly when product stock status is already ‘onbackorder’.
• Fix – Removed unnecessary is_on_backorder() check that prevented stock quantity tracking.
• Fix – Properly retrieve order item objects after add_product() to enable meta data copying.
• Fix – Updated version number consistency across all plugin files.
• Fix – Updated @version tags in PHPDoc blocks to reflect current version.
• Fix – Made bulk action text translatable for better localization support.
• Fix – Added return value to is_request() method for better error handling.
