使用瞬变在导航中添加通知气泡通知

我想在管理中的导航项旁边添加一个漂亮的小通知气泡。但我不想每次都触发一个post查询来显示小气泡中的值，从而减慢整个管理的速度。希望将这一整数值加载到临时缓存中，以便在菜单中显示。

开发一个注册自定义帖子类型的自定义插件。这会自动在admin中创建导航项，我想在其中添加气泡。气泡中的值将从一个简单的查询中提取，该查询显示有多少帖子（这个CPT）被分配给了自定义分类法。例如，如果帖子已分配给自定义术语“待定审核”，则添加到气泡计数。

虽然我不知道如何过渡到使用瞬态缓存来存储和检索数据，但这个函数很有魅力。。。。如有任何建议，将不胜感激。谢谢

WP-Admin显示(1)更新，但没有更新插件、主题或WordPress

我有一个奇怪的问题，在我的wp管理，它说有一个更新需要。然而，我检查了主题、插件，甚至重新安装了最新版本的Wordpress，它仍在向我显示更新。我还删除了我的缓存插件，并做了各种其他任务试图修复它，但没有运气。有人知道是什么原因导致了这一问题，以及/或者我如何解决这一问题吗？这很烦人。谢谢你的帮助。以下是两张图片：
