如果值为0,则隐藏自定义运费成本

你的代码有点过时 woocommerce_cart_calculate_fees 动作钩有 WC_Cart 对象作为可用参数。

global $woocommerce 具有 $woocommerce->cart $woocommerce->customer 现在简单地替换为:

• WC()->cart 对象)
• WC()->customer (以 WC_Customer 对象)

要使费用仅适用于您的特定条件,请尝试以下重新访问的代码:

add_action( 'woocommerce_cart_calculate_fees', 'conditional_shipping_surcharge', 10, 1 );
function conditional_shipping_surcharge( $cart ) {

    $targeted_weight = 100; // Define the starting targeted weight
    $cart_weight     = $cart->get_cart_contents_weight();
    $shipping_state  = WC()->customer->get_shipping_state();
    $percent         = 0; // Initializing

    if ( $cart_weight >= $targeted_weight ) {
        // 5 € of surcharge per 100kg for Sardinia
        if ( in_array( $shipping_state, array('CA', 'NU') ) ) {
            $percent = 5;
        }
        // 3 € of surcharge per 100kg for Sicily
        elseif ( in_array( $shipping_state, array('AG', 'CL') ) ) {
            $percent = 3;
        }
        // 2 € of surcharge per 100kg for Calabria
        elseif ( in_array( $shipping_state, array('CZ', 'CS') ) ) {
            $percent = 2;
        }
    }

    if( $percent > 0 ){
        // Fee calculation
        $fee = $cart_weight * $percent / 100;

        // Add calculated fee (Taxable for "standart" default tax class)
        $cart->add_fee( __("Maggiorazione Isole & Calabria", "woocommerce"), $fee, true );
    }
}

代码放在活动子主题(或活动主题)的function.php文件中。测试和工作。
