推荐答案
这是一种经过测试且有效的解决方案，用于删除您无法添加其他"消息.
背景:Woocommerce不会直接挂钩所有通知.实际上，购物车错误会作为抛出的异常硬编码到class-wc-cart.php中.
Background: Woocommerce does not expose direct hooks to all of its notices. The cart errors are actually hardcoded into class-wc-cart.php as thrown Exceptions.
生成错误异常时，会将它们添加到我们可以使用以下方法访问，解析和更改的通知列表中:
When Error Exceptions are generated, they get added to a list of Notices that we can access, parse, and alter using the methods:
- wc_get_notices()将所有通知作为数组返回
- wc_set_notices()可让您直接设置通知数组
- wc_get_notices() returns all notices as an array
- wc_set_notices() lets you set the notices array directly
为了访问通知并对其进行更改，您需要挂钩一个在woocommerce生成其通知后将触发的操作，但是在显示该页面之前.您可以执行以下操作: woocommerce_before_template_part
In order to access the notices and alter them, you need to hook an action that will fire after woocommerce has generated its notices, but BEFORE the page is displayed. You can do that with the action: woocommerce_before_template_part
这里是完整的工作代码，专门删除了"您不能添加其他"通知:
Here is complete working code that specifically removes "You cannot add another" notices:
add_action('woocommerce_before_template_part', 'houx_filter_wc_notices');
function houx_filter_wc_notices(){
$noticeCollections = wc_get_notices();
/*DEBUGGING: Uncomment the following line to see a dump of all notices that woocommerce has generated for this page */
/*var_dump($noticeCollections);*/
/* noticeCollections is an array indexed by notice types. Possible types are: error, success, notice */
/* Each element contains a subarray of notices for the given type */
foreach($noticeCollections as $noticetype => $notices)
{
if($noticetype == 'error')
{
/* the following line removes all errors that contain 'You cannot add another'*/
/* if you want to filter additiona errors, just copy the line and change the text */
$filteredErrorNotices = array_filter($notices, function ($var) { return (stripos($var, 'You cannot add another') === false); });
$noticeCollections['error'] = $filteredErrorNotices;
}
}
/*DEBUGGING: Uncomment to see the filtered notices collection */
/*echo "<p>Filtered Notices:</p>";
var_dump($noticeCollections);*/
/*This line overrides woocommerce notices by changing them to our filtered set. */
wc_set_notices($noticeCollections);
}
旁注:如果要添加自己的通知，则可以使用wc_add_notice().您必须阅读woocommerce文档以了解其工作原理: 关于WooCommerce文档的wc_add_notice
Side note: If you wanted to add your own notice, you can use wc_add_notice(). You'll have to read the woocommerce documentation to see how it works: wc_add_notice on WooCommerce docs
