当我将woocommerce-2.3.13版本更改为woocommerce-2.4.6时，我收到此错误：
WooCommerce：SyntaxError：意外的令牌＆lt;
据我所知，当我在php文件中添加脚本标记（＆lt; script＆gt;）时，打开的脚本标记DATETIME会出错，这意味着它不会读取脚本标记。
我添加了我的插件（在php文件中），将结帐流程与支付网关连接，以重定向到银行列表页面。当我尝试使用JavaScript重定向时，会出现此错误。重定向功能<无效，因此我使用的是JavaScript。
header("location:$url")我试过
?>
<script type='text/javascript'>
window.location.href="<?php echo $url; ?>";
</script >
<?
但是我遇到了同样的错误。
答案 0 :(得分：0)
当处理WooCommerce结帐时，它要求网关返回一个数组（然后转换为JSON）告诉结帐是否成功。从v1开始就是这样。
在2.4+中，这更加严格，因为响应必须是有效的JSON。响应中的任何其他内容（例如HTML，通知或空格）都将使此JSON无效，您可能会看到以下错误：
SyntaxError: Unexpected token
请参阅此博文https://mikejolley.com/2015/11/12/debugging-unexpected-token-in-woocommerce-2-4/
中的调试方法我按照该博客文章中的所有说明，禁用了所有插件，结果发现JSON响应发回错误而不是正确格式化的JSON。我的回答是：

就我而言，WooCommerce PayPal Pro支付网关和WooCommerce产品供应商存在问题，因为默认情况下我的DigitalOcean服务器上没有安装cURL。使用WooCommerce产品供应商，每次客户下订单时，供应商都会通过PayPal Mass Payments获得付款佣金。要使PayPal批量付款生效，您必须确保在PayPal帐户上启用批量付款，并确保服务器上已安装cURL 。
我一安装cURL就行了。以下是如何在DigitalOcean https://www.digitalocean.com/community/questions/curl-is-not-installed-in-your-php-installation
上安装cURL希望这可以帮助那些人。
