如何在可變產品的下拉選項中查看 SKU 代碼？我試圖使用此代碼，但它只是為了在woocommerce中查看價格選項。原因最近我使用其他代碼，但 SKU 不是動態的，當我更改和變量選項。add_filter( 'woocommerce_variation_option_name', 'display_price_in_variation_option_name' );function display_price_in_variation_option_name( $term ) {  global $wpdb, $product;  if( isset( $product ) ) {    $result = $wpdb->get_col( "SELECT slug FROM {$wpdb->prefix}terms WHERE name = '$term'" );    $term_slug = ( !empty( $result ) ) ? $result[0] : $term;    $query = sprintf( "SELECT postmeta.post_id AS product_id      FROM {$wpdb->prefix}postmeta postmeta      LEFT JOIN {$wpdb->prefix}posts products ON ( products.id = postmeta.post_id )      WHERE postmeta.meta_key LIKE 'attribute_%%'      AND postmeta.meta_value = '%s'      AND products.post_parent = %d", $term_slug, $product->get_id() );    $variation_id = $wpdb->get_col( $query );    $parent = wp_get_post_parent_id( $variation_id[0] );    if ( $parent > 0 ) {      $_product = new WC_Product_Variation( $variation_id[0] );      $itemPrice = strip_tags (wc_price( $_product->get_price() ));      //this is where you can actually customize how the price is displayed      return $term . ' ('. $itemPrice .')';    }  }}基于此代碼，我如何分配 get-sku 并在前端顯示的變體選項區域旁邊查看。如果有人能幫助我解決問題，我真的知道。
