WooCommerce Bulk Price Setup with ACF Repeater Fields

  Want to offer different prices based on order quantity? Use ACF to define quantity-based pricing for WooCommerce products. You’ll also update the price dynamically when a user adds an item to their cart.

Step 1: Install ACF Plugin

Ensure Advanced Custom Fields (ACF) plugin is active on your WordPress site.

Step 2: Create Quantity-Based Price Fields

Navigate to Custom Fields > Add New. Add a Repeater with fields for `quantity` and `price`. Assign the group to WooCommerce products.

Step 3: Show Pricing Options on Product Page

Paste this code in your `functions.php` or plugin to display available prices:

function display_all_prices_on_product_page() {
    global $post;

    // Check if the current post is a product
    if ( 'product' !== get_post_type( $post ) ) {
        return;
    }

    // Get the ACF repeater field data
    $quantity_and_prices = get_field( 'quantity_and_prices', $post->ID );

    // Display the prices if available
    if ( $quantity_and_prices ) {
        echo '<h2>All Prices:</h2>';
        echo '<ul>';
        foreach ( $quantity_and_prices as $item ) {
            $quantity = (int) $item['quantity'];
            $price    = (float) $item['price'];
            echo '<li>' . esc_html( $quantity ) . ' - ' . wc_price( $price ) . '</li>';
        }
        echo '</ul>';
    }
}
add_action( 'woocommerce_single_product_summary', 'display_all_prices_on_product_page', 25 );

Step 4: Update Price Dynamically in Cart

To calculate final price dynamically:

function update_price_by_qty( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return;

    foreach ( $cart->get_cart() as $cart_item ) {
        $product = $cart_item['data'];
        $pricing = get_field( 'quantity_and_prices', $product->get_id() );

        if ( $pricing ) {
            $qty = (int) $cart_item['quantity'];
            foreach ( $pricing as $entry ) {
                if ( $qty === (int) $entry['quantity'] ) {
                    $product->set_price( (float) $entry['price'] );
                    break;
                }
            }
        }
    }
}
add_action( 'woocommerce_before_calculate_totals', 'update_price_by_qty', 10 );

This solution empowers your WooCommerce store to adjust product pricing based on user-selected quantity dynamically.
