To override WooCommerce variation prices dynamically, apply cross-layer filters on the variation read and price-aggregation pipelines. This applies context-sensitive pricing rules per request without permanently mutating the stored product database values.

Role-based variation prices leak between users when the WooCommerce price cache is shared across contexts. Extending the woocommerce_get_variation_prices_hash filter to include per-user roles and flags ensures cache isolation and prevents incorrect cross-user pricing.

The best way to apply time-based discounts to WooCommerce product variations is wiring context-aware filters across woocommerce_product_variation_get_price and woocommerce_variation_prices_price pipelines. This keeps catalog ranges and variation pages in sync with the active discount window.

WooCommerce caches variation prices globally by default, which breaks dynamic role-based pricing. Modifying the variation prices hash to include user-specific context variables forces WordPress to generate and store separate cache entries for each role.

To keep WooCommerce catalog price ranges in sync with custom pricing, apply filters across both the variation read and price-aggregation pipelines. Overriding woocommerce_variation_prices_regular_price and woocommerce_variation_prices_sale_price ensures the displayed range reflects user-specific overrides.

To bust WooCommerce variation price cache when custom pricing rules change, implement cache invalidation through the woocommerce_get_variation_prices_hash filter. Extending this hash with active rule flags ensures stale cached prices are automatically regenerated upon rule updates.
