如何根据商品数量和特定类别禁用送货方式 [英] How to disable shipping method based on item count and a certain category

问题描述

我一直在寻找一种有选择地禁用两种运输方式的方法

I have been looking for a way to condtionally disable two shipping methods

• 餐桌费率
• 距离率

基于项目数.

按项目计数"我不是指数量，而是指购物车中有多少种不同的产品.购物车中的IE 2灯和3个表的项目计数为2，总数量为5.

By item count I do not mean quantity, I mean how many different products are in the cart. IE 2 Lamps and 3 tables in the cart would be an item count of 2 and a combined quantity of 5.

我还要确保此规则仅对特定类别有效.

I would also like to ensure this rule is in effect for a certain category only.

我尝试过:

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 );

推荐答案

您可以使用以下解释，并在代码中添加注释

You could use the following, explanation with comments added in the code

此代码中必须满足的条件:

Conditions that must be met in this code are:

• 购物车中至少有3个订单项
• 1个或更多产品属于'categorie-1'类别
如果满足前两个条件，则
• 'distance_rate'和/或'table_rate'未设置

• At least 3 line items in cart
• 1 or more products belong to the 'categorie-1' category
• 'distance_rate' and/or 'table_rate' become unset if the previous 2 conditions are met

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 );
