php - 当购物车商品具有特定运输类别时禁用运输方式？

Question

如果购物车中有特定的送货类别，我会尝试禁用送货方式。我正在使用最新的 woocommerce 版本。

以下是我的任务代码。 它位于主题的 functions.php 文件的末尾。

遗憾的是它不起作用。

add_filter( 'woocommerce_package_rates', 'businessbloomer_hide_free_shipping_for_shipping_class', 10, 2 );
function businessbloomer_hide_free_shipping_for_shipping_class( $rates, $package ) {
    $shipping_class_target = 513;           // ID OF MY SHIPPING_CLASS
    $in_cart = false;
    foreach( WC()->cart->cart_contents as $key => $values ) {
        if( $values[ 'data' ]->get_shipping_class_id() == $shipping_class_target ) {
            $in_cart = true;
            break;
        } 
    }
    if( $in_cart ) {
        unset( $rates['flat_rate:2'] );     //VALUE:ID OF MY SHIPPING METHOD
    }
    return $rates;
}

我已经测试过稍微简化您的代码(使用我的 WC 设置的 ID)并且有效:

add_filter( 'woocommerce_package_rates', 'custom_hide_shipping_methods', 10, 2 );
function custom_hide_shipping_methods( $rates, $package ) {
    foreach( WC()->cart->get_cart() as $cart_item  ) {
        $product = $cart_item[ 'data' ]; // The WC_Product object
        $shipping_class_id = $product->get_shipping_class_id();

        if( isset($rates['flat_rate:2']) && $shipping_class_id == 513 ) { // <== ID OF MY SHIPPING_CLASS
            unset( $rates['flat_rate:2'] ); // Removing specific shipping method
            break; // we stop the loop
        }
    }
    return $rates;
}

所以您的代码也应该可以工作 (如果您设置了正确的 ID)

BUT you need (after saving your code to the function.php file of your active theme):

1. To remove all cart items that are remaining in cart when testing.

2. To refresh the shipping caches:
   To do it, you can go in a shipping zone and disable one "flat rate" (for example) and "save". Then re-enable that "flat rate" and "save". You are done.

现在您可以再次测试，它应该可以工作了
