按产品类别在购物车中显示个性化消息，鼓励您继续购物

Question

使用以下代码，我可以在购物车中显示一条消息，鼓励用户继续购买更多产品，但该消息对于所有产品类别永久显示，如何使其适用于一个或多个特定类别？谢谢你能帮助我。    add_action( 'woocommerce_before_cart_table', 'woo_add_continue_shopping_button_to_cart_products' );function woo_add_continue_shopping_button_to_cart_products() { echo '<div class="woocommerce-message">'; echo ' <a href="https://midomain.com/" class="button">Continue Shopping →</a> Do you want more products?'; echo '</div>';}

Answer 1

您可以创建要显示“继续购物”链接的类别数组，以及购物车中当前所有类别的数组。然后您可以使用array_intersect()来查看两个数组之间是否存在匹配。如果是，请显示链接：

add_action( 'woocommerce_before_cart_table', 'woo_add_continue_shopping_button_to_cart_products' );

function woo_add_continue_shopping_button_to_cart_products() {

    // Define categories which should show the keep shopping link

    $keep_shopping = array( 'Music', 'Clothing' );

    // Check categories in the cart

    foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {

        $terms = get_the_terms( $cart_item['product_id'], 'product_cat' );

        if ( !empty($terms) ) {

            foreach ($terms as $key => $term) {

                $order_cats[$term->term_id] = $term->name;

            }

        }

    }

    // Get array of category matches

    $cat_matches = array_intersect( $keep_shopping, $order_cats );

    if ( count( $cat_matches ) > 0 ) {

        // 1 or more matches, show keep shopping link

        printf( '<div class="woocommerce-message"><a href="%s" class="button">Continue Shopping →</a> Do you want more products?</div>', get_permalink( wc_get_page_id( 'shop' ) ) );

    }

}
