Wordpress商品详情页新增Buy on amazon/ebay跳转按钮

提示：本文内容严禁在其他平台转载！劳动成果不易，希望能相互体谅。这个亚马逊商品链接跳转不是用插件编辑，而是在woocommerce插件源码中新增。（大家要在弄之前先备份好文件，或者在本地先试。不敢改代码的可以找我要写好的插件版不影响源码,严禁将本插件在其他网上转卖！可以根据实际主题页面定制按钮，加Q：1023652334）

注意：根据文章改代码的，woocommerce插件不要升级，或者非要升级那就再添加一次。插件的不会影响woocommerce的升级

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 3.0.0*/if ( ! defined( 'ABSPATH' ) ) {exit; // Exit if accessed directly
