GFプロダクトアドオンオプションの合計がになるようにするには、カートの合計からを除いてください。WooCommerce - Gravity Forms製品アドオン - 選択したオプションを除外合計カートから合計
私が販売している製品は、$ 100です。私は100ドル+税だけであるカート合計が必要です。私はオプション合計がそれに含まれることを望んでいません。カートの商品説明に表示することは大丈夫です。これらのオプションの合計額は毎月繰り返され、顧客がオフラインで支払うので、前払いをする必要はありません。
プラグインのソースコード：以下WooCommerce - Gravity Forms Product Add-Ons
コードは、プラグイン内で見つかった "gravityforms-製品アドオン-cart.php" からです。私はどこから始めるべきかわからない。

functions.php自体を追加し、$ totalsを印刷してそれに応じて値を変更してみてください –
