ItemEligibility::format_variation_summary │ public static │ WC 10.9.0

Render the variation's attribute summary as a single flat line.

Used both at write time (snapshotted into _review_variation_summary) and at render time by the Review Order row template, so the two places always agree on what label the customer sees and what the comment stores. Restricted to actual variation attribute slugs so personalisation / add-on / engraving / gift-message meta from third-party plugins isn't accidentally folded into the public review snapshot. Returns an empty string for simple products or when the variation product can no longer be loaded to identify its attribute slugs.

Keys in the line item meta are stored without the attribute_ prefix (see WC_Order_Item_Product::set_variation()), so we strip the prefix from the live variation's attribute keys to match.

Method of the class: ItemEligibility{}

No Hooks.

Returns

null. Nothing (null).

Usage

$result = ItemEligibility::format_variation_summary( $item ): string;

$item(WC_Order_Item_Product) (required)

Order line item.
