1How do you create dynamic pricing with conditional fields?
Use hooks like `woocommerce_before_calculate_totals` to adjust item prices based on custom field values stored in cart item data. Pair with Advanced Custom Fields or custom metaboxes. Apply logic for materials, engravings, or rush fees. Store decisions in order item meta for fulfillment visibility.
Normalize conditional rules in arrays or config files so non-developers can update pricing logic.
2How can add-on plugins like YITH accelerate builds?
YITH Product Add-ons or WooCommerce Product Add-Ons Ultimate provide UI builders for radio buttons, color swatches, and upload fields. They support conditional logic, price modifiers, and layout control. Extend via template overrides if you need bespoke markup.
Sync plugin fields with translations using WPML or Weglot to keep customizations multilingual.
3How do you leverage hooks for bundle products?
Use `woocommerce_bundled_item_filter_price` or composite product filters to adjust pricing based on selected components. Inject custom validation via `woocommerce_add_to_cart_validation` to enforce minimum or matching selections. Display summaries in cart using `woocommerce_get_item_data`.
Cache bundle calculations for repeat views to prevent slow add-to-cart events on large kits.
4How do you validate user inputs?
Run server-side checks in `woocommerce_add_to_cart_validation` and front-end validation via custom JavaScript tied to field selectors. Sanitize uploads, restrict file types, and scan for malware if accepting assets. Provide inline error messages with actionable guidance.
Save validation rules in JSON so QA teams can test scenarios systematically.
5How do you style custom options with Elementor Pro?
Use Elementor’s form widgets tied to WooCommerce hooks or render shortcodes inside product templates. Map CSS variables for consistent spacing, add icons, and create accordions for complex option sets. Ensure styles degrade gracefully on mobile and dark modes.
Leverage Elementor display conditions to show custom option sections only when relevant (e.g., specific categories).
