在WooCommerce 3中有条件地设置特定产品的购物车价格 [英] Conditionally set cart item prices for specific products in WooCommerce 3

问题描述

在WooCommerce中，我使用此答案中的一些代码：

如果已经购买了产品，请将WooCommerce购物车项目价格设置为零

In WooCommerce I am using some code from this answer:
Set WooCommerce cart item price to zero if the product has already been bought

它可以与一种产品一起使用，但我想使其与多种产品一起使用。

It works great with one product, but I would like to make it work with several products.

因此，如果客户已经购买了以下代码，对于特定产品，将购物车价格更改为 $ 0.00 如果不是，则价格设置为 $ 100 （首次购买） ：

So the code below, for a specific product, change the cart item price to $0.00 if customer has already purchased and if not the price is set to $100 (for the first purchase):

    add_action( 'woocommerce_before_calculate_totals', 'conditionally_change_cart_items_price', 10, 1 );
function conditionally_change_cart_items_price( $cart_object ) {

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;


    $targeted_product_id = 1107;

    // Set Here your custom price (1st purshase)
    $custom_price = 100; // First purshase for product ID 1092

    // Detecting if customer has already bought The targeted product (1092)
    if( is_user_logged_in() ){
        $customer      = wp_get_current_user();
        $customer_id   = $customer->ID; // customer ID
        $customer_email = $customer->email; // customer email

        if( wc_customer_bought_product( $customer_email, $customer_id, $targeted_product_id) )
            $custom_price = 0; // Set to 0 for other purchases (product ID 1092)
    }

    foreach ( $cart_object->get_cart() as $cart_item ) {
        // When targeted product is in cart we change the price
        if ( $cart_item['product_id'] == $targeted_product_id ) {
            // Woocommerce 3+ compatibility
            if ( version_compare( WC_VERSION, '3.0', '<' ) )
                $cart_item['data']->price = $custom_price;
            else
                $cart_item['data']->set_price( $custom_price );
        }
    }
}

我如何使其工作

推荐答案

您必须创建一个包含所有目标产品ID的数组，然后应该检查客户是否已经在foreach循环中购买了该产品：

You have to create an array with all target product ids and then you should check if a customer bought this product already in the foreach loop:

add_action( 'woocommerce_before_calculate_totals', 'conditionally_change_cart_items_price', 10, 1 );

function conditionally_change_cart_items_price( $cart_object ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    // add as many ids as you need
    $targeted_product_ids = array( 1107, 1108, 1109 );

    // Set Here your custom price (1st purshase)
    $custom_price = 100; // First purshase for target product


    if ( is_user_logged_in() ) {
        $customer       = wp_get_current_user();
        $customer_id    = $customer->ID; // customer ID
        $customer_email = $customer->email; // customer email

        foreach ( $cart_object->get_cart() as $cart_item ) {
            // When targeted product is in cart we change the price
            if ( in_array( $cart_item['product_id'], $targeted_product_ids ) ) {

                // Detecting if customer has already bought The targeted product
                if ( wc_customer_bought_product( $customer_email, $customer_id, $targeted_product_id ) )
                    // Set to 0 for other purchases
                    $custom_price = 0;

                // Woocommerce 3+ compatibility
                if ( version_compare( WC_VERSION, '3.0', '<' ) )
                    $cart_item['data']->price = $custom_price;
                else
                    $cart_item['data']->set_price( $custom_price );
            }
        }
    }
}
