在WooCommerce中，我的产品列在类别页面中，其中包含详细信息以及＆＃34;添加到购物车＆＃34;按钮。当用户点击按钮页面时刷新并出现顶部成功消息并显示视图购物车按钮。
当用户多次执行此操作时（添加多个项目）：
我需要列出未登录用户的购物车添加产品。任何人都可以为此提供解决方案......
这是我的loop / add-to-cart.php代码：
echo apply_filters( 'woocommerce_loop_add_to_cart_link',
sprintf( '<a href="%s" rel="nofollow" data-product_id="%s" data-product_sku="%s" data-quantity="%s" class="button %s product_type_%s">%s</a>',
esc_url( $product->add_to_cart_url() ),
esc_attr( $product->id ),
esc_attr( $product->get_sku() ),
esc_attr( isset( $quantity ) ? $quantity : 1 ),
$product->is_purchasable() && $product->is_in_stock() ? 'add_to_cart_button' : '',
esc_attr( $product->product_type ),
esc_html( $product->add_to_cart_text() )
),
$product );
答案 0 :(得分：2)
更新并检查了代码（2）
购物车计数工作和购物车页面仅显示非登录用户的最后购物车项目1）当您未登录时，会显示仅最后一个购物车项目 2）当您登录时，将显示所有购物车项目。
可以编辑woocommerce cart.php 模板。
首先需要复制到您的
templates中的活动子主题（或主题）文件夹，WooCommercewoocommerce文件夹插件文件夹（如果尚未完成）并重命名新添加的文件夹woocommerce。 See this related documentation
完成后，您将打开修改 cart/cart.php 文件并将代码替换为以下内容：
<?php
/**
* Cart Page
*
* This template can be overridden by copying it to yourtheme/woocommerce/cart/cart.php.
*
* HOWEVER, on occasion WooCommerce will need to update template files and you
* (the theme developer) will need to copy the new files to your theme to
* maintain compatibility. We try to do this as little as possible, but it does
* happen. When this occurs the version of the template file will be bumped and
* the readme will list any important changes.
*
* @see https://docs.woocommerce.com/document/template-structure/
* @author WooThemes
* @package WooCommerce/Templates
* @version 2.3.8

然后保存。
正如您将在第31行到第38行（在cat foreach循环之外）看到的那样，我添加了一些代码来计算总购物车数量并将计数器初始化为零。此外，我暂时显示了购物车数量（您可以删除此行，因为它仅用于测试）。
我添加了一个条件if语句，该语句将执行您期望的操作：
if( is_user_logged_in() || ( !is_user_logged_in() && $count == $cart_count) ):
在这个条件之后，我增加 $count 变量（处于条件中）。
现在经过测试并完美运行......
