Dynamic Quantity Price Updater for WooCommerce

Updates the displayed WooCommerce product price when quantity changes. Optional separate line Total with configurable single product page hook position.

Features

• Instant price recalculation on quantity changes
• Works with simple and variable products (listens to found_variation)
• Compatible with WooCommerce Blocks price markup (keeps currency symbol span)
• Optional separate line Total with customizable label
• Choose where to output the Total line from common single product hooks
• Accessible updates via ARIA live region

Settings

WP Admin → WooCommerce → Quantity Price Updater

• Update main product price dynamically: When enabled, replaces the product price on the page as quantity changes.
• Enable separate Total line: Outputs a dedicated total amount element on single product pages.
• Hook position: Choose where the Total is output.
• Total label: Text shown before the recalculated total.

Frontend Behavior

• Quantity changes trigger real-time recalculation.
• Variation selection updates the unit price before recalculation.
• If “separate Total line” is enabled, a paragraph with id qpu-total is rendered at the selected hook and updated live.
• If “Update main product price dynamically” is enabled, the existing price on the page is updated in-place. With WooCommerce Blocks, only the amount is replaced while preserving the currency symbol markup.

Theme/Block Compatibility

The script tries several selectors including classic templates and Woo Blocks:

• .summary .price .amount, .summary .price bdi
• .wp-block-woocommerce-product-price …, .wc-block-components-product-price …
  If your theme uses different price wrappers, modify the selectors in the jQuery to match.
