根据不用于变体的产品属性隐藏多种 WooCommerce 运输方式

Question

在我的 WooCommerce 网站上，每个产品都有四个属性（尺寸、颜色、季节和品牌）。尺寸和颜色属性用于变化，而季节和品牌不用于变化。

我设置了 3 种送货方式：无最低订单要求的免费送货 (ID 17)、最低订单为 100 欧元的免费送货 (ID 8)，最后是 9.99 欧元的付费送货 (ID 1)。

当购买 S24 季节的产品时，我希望最低订单为 100 欧元免运费 (ID 17) 和付费运费 (ID 1) 9.99 欧元，而如果您购买 F23 季节的产品，则免费必须激活最低订单为 100 欧元的运费 (ID 8) 和 9.99 欧元的付费运费 (ID 1)。在最后一种情况下，如果您购买了至少一件 S24 赛季的产品和至少一件 F23 赛季的产品，则必须激活无最低订购量的免运费（ID 17）。

这是起始代码，但它仅适用于用于变体的属性：

add_filter( 'woocommerce_package_rates', 'hide_shipping_method_based_on_product_attribute', 10, 2 );
function hide_shipping_method_based_on_product_attribute( $rates, $package ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    // Product Attribute taxonomy (start always with "pa_")
    $taxonomy = 'pa_season'; // Example for "Season"

    // Array of Shipping method rate ID and term(s) slug(s) pairs
    $data_array = array(
        'free_shipping:8'     => array('s24'),
        'free_shipping:17'    => array('f23'),
        'flat_rate:1'         => array('f23'),
    );

    // Loop through items in the current shipping package
    foreach( $package['contents'] as $item ){
        // Get the parent variable product if it's a product variation
        $product = $item['variation_id'] > 0 ? wc_get_product($item['product_id']) : $item['data'];
            
        // Loop through our data array
        foreach( $data_array as $rate_id => $term_slugs ) {
            // loop through product attributes
            foreach($product->get_attributes() as $attribute ) {
                if( $attribute->get_taxonomy() === $taxonomy && isset($rates[$rate_id]) 
                && count( array_intersect($attribute->get_slugs(), $term_slugs) ) > 0 ) {
                    unset($rates[$rate_id]);
                }
            }
        }
    }
    return $rates;
}

Answer 1

以下将处理您所需的所有案例：

• 找到“S24”术语：免费送货（ID 17，最低小计金额为 100 欧元）并激活付费送货，
• 找到“F23”术语：免费送货（ID 8，最低小计金额为 100 欧元）并激活付费送货，
• 找到“S24”和“F23”条款：免运费（ID 17，最低小计金额为 100 欧元）已激活。

重要提示：您需要从两种免费送货方式设置中删除，即最小订单金额限制，因为它是在代码中处理的。

尝试以下操作：

add_filter( 'woocommerce_package_rates', 'hide_shipping_method_based_on_product_attribute', 10, 2 );
function hide_shipping_method_based_on_product_attribute( $rates, $package ) {
    $free_min_subtotal = 100; // Set the minimal amount for free shipping
    $taxonomy = 'pa_season'; // Product Attribute taxonomy (start always with "pa_")
    $has_s24 = $has_f23 = false; // Initializing

    $cart_subtotal = $package['cart_subtotal']; // Or use $package['contents_cost'] to exclude taxes
    error_log('cart_subtotal: '.$package['cart_subtotal'].' | contents_cost: '.$package['contents_cost']);
    // Loop through items in the current shipping package
    foreach( $package['contents'] as $item ){
        // Get the parent variable product if it's a product variation
        $product = $item['variation_id'] > 0 ? wc_get_product($item['product_id']) : $item['data'];
        // Loop through product attributes
        foreach($product->get_attributes() as $attribute ) {
            // Check for "Season" PA
            if( $attribute->get_taxonomy() === $taxonomy ) {
                $has_s24 = in_array( 's24', $attribute->get_slugs() );
                $has_f23 = in_array( 'f23', $attribute->get_slugs() );
            }
        }
    }

    // Case 1 (term "s24" found)
    if ( isset($rates['free_shipping:17']) && isset($rates['flat_rate:1']) && $has_s24 && ! $has_f23 ) {
        if ( isset($rates['free_shipping:8']) ) {
            unset($rates['free_shipping:8']); // remove Free Shipping 8
        }
        // Handle minimum cart amount for free shipping
        if ( isset($rates['free_shipping:17']) && floatval($cart_subtotal) < $free_min_subtotal ) {
            unset($rates['free_shipping:17']); // remove Free Shipping 17 (required subtotal is lower)
        }
    } 
    // Case 2 (term "f23" found)
    elseif ( isset($rates['free_shipping:8']) && isset($rates['flat_rate:1']) && $has_f23 && ! $has_s24 ) {
        if ( isset($rates['free_shipping:17']) ) {
            unset($rates['free_shipping:17']); // remove Free Shipping 17
        }
        // Handle minimum cart amount for free shipping
        if ( isset($rates['free_shipping:8']) && floatval($cart_subtotal) < $free_min_subtotal ) {
            unset($rates['free_shipping:8']); // remove Free Shipping 8 (required subtotal is lower)
        }
    } 
    // Case 3 (terms "s24" and "f23" found)
    elseif ( isset($rates['free_shipping:17']) && $has_s24 && $has_f23 ) {
        if ( isset($rates['free_shipping:8']) ) {
            unset($rates['free_shipping:8']); // remove Free Shipping 8 
        }
        if ( isset($rates['flat_rate:1']) ) {
            unset($rates['flat_rate:1']); // remove Flat rate 1 
        }
    } 
    // Fallback: For security regarding free shipping and minimal required subtotal
    elseif ( floatval($cart_subtotal) < $free_min_subtotal ) {
        if ( isset($rates['free_shipping:8']) ) {
            unset($rates['free_shipping:8']); // remove Free Shipping 8 
        }
        if ( isset($rates['free_shipping:17']) ) {
            unset($rates['free_shipping:17']); // remove Free Shipping 17
        }
    }

    return $rates;
}

代码位于子主题的functions.php 文件中（或插件中）。应该可以。
