代碼放在您的活動子主題(或主題)的function.php文件或也以任何插件文件。
此代碼對Woocommerce 3+測試和工程
或許這將幫助:https://docs.woocommerce.com/document/minmax-quantities/(注意,這裏沒有人會編寫代碼你最好的選擇是嘗試一些東西,並詢問你碰到的具體問題。) – jdv
我只想要一個提示/鏈接/ plugin.anything,可以提供幫助。謝謝 –
我設法在functions.php中添加一段代碼,但是這會在購物車add_action('woocommerce_check_cart_items','wh_wc_minimum_order_amount')中添加x2項總數。 函數wh_wc_minimum_order_amount() { $ minimum = 2; (WC() - > cart-> get_cart_contents_count()%$ minimum!= 0) { // wc_clear_notices(); wc_add_notice(sprintf('錯誤:查看產品數量',$ minimum),'error'); } } –
