']',      'desc_tip'    => 'true',            'description' => __( 'Enter the Bulk price here.', 'woocommerce' ),        'label' => __( 'Custom Field', 'woocommerce' ),        'value' => get_post_meta( $variation->ID, 'bulk_price', true )     ));}// 2. Save custom field on product variation saveadd_action( 'woocommerce_save_product_variation', 'Save_bulk_price_variations', 10, 2 );function Save_bulk_price_variations( $variation_id, $i ) {    $bulk_price = $_POST['bulk_price'][$i];    if ( isset( $bulk_price ) ) {        update_post_meta( $variation_id, 'bulk_price', esc_attr( $bulk_price ) );    }}// 3.

'</span>';    return $variation_data;}

Answer 1

您使用相同的钩子 2x，这就足够了（不再需要第 4 步）

foreach不需要使用循环来获取子 ID

// 3 & 4. Store custom field value into variation data + show the bulk price on product variations

function add_bulk_price_variation_data( $variation_data, $product, $variation ) {

    $bulk_price = get_post_meta( $variation_data[ 'variation_id' ], 'bulk_price', true);

    if ( $bulk_price ) {

        $variation_data['price_html'] .= ' <span class="price-suffix">' . __( $bulk_price , "woocommerce") . '</span>';

    }

    return $variation_data;

}

add_filter( 'woocommerce_available_variation', 'add_bulk_price_variation_data', 10, 3 );
