如何根据项目数量和特定类别禁用送货方式

Question

我一直在寻找一种有条件地禁用两种送货方式的方法

• table 率
• 距离率

基于项目数。

我指的不是数量，而是购物车中有多少种不同的产品。 IE 2 Lamps and 3 tables in the cart would be an item count of 2 and the combined quantity of 5.

我还想确保此规则仅对特定类别有效。

我试过了：

function hide_shipping_count_based( $rates, $package ) {

    // Set count variable
    $cart_count = 0;

    // Calculate cart's total
    foreach( WC()->cart->cart_contents as $key => $value) {
        $cart_count ++;
    }

    // only if the weight is over 150lbs find / remove specific carrier
    if( $cart_count > 2 ) {
        // loop through all of the available rates

        unset( $rates[ 'distance_rate' ] );
        unset( $rates[ 'table_rate' ] );

    }

    return $rates;
}

add_filter( 'woocommerce_package_rates', 'hide_shipping_count_based', 10, 2 );

Answer 1

您可以使用下面的解释，并在代码中添加注释

此代码必须满足的条件是：

• 购物车中至少有 3 个订单项
• 1 个或多个产品属于 'categorie-1' 类别
• 'distance_rate' and/or 'table_rate' 如果满足前两个条件则取消设置

function hide_shipping_count_based( $rates, $package ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return;

    // Count line items
    $count =  count( $package['contents'] );

    // Set variable
    $found = false;

    // Set term (category)
    $term = 'categorie-1';

    // Check count
    if( $count > 2 ) {

        // Loop through line items
        foreach( $package['contents'] as $line_item ) {
            // Get product id
            $product_id = $line_item['product_id'];

            // Check for category
            if ( has_term( $term, 'product_cat', $product_id ) ) {
                $found = true;
                break;
            }
        }
    }

    // True
    if ( $found ) {
        // Loop trough rates
        foreach ( $rates as $rate_key => $rate ) {
            // Targeting
            if ( in_array( $rate->method_id, array( 'distance_rate', 'table_rate' ) ) ) {
                unset( $rates[$rate_key] );
            }
        }
    }

    return $rates;
}
add_filter( 'woocommerce_package_rates', 'hide_shipping_count_based', 100, 2 );
