我从2011年起就一直在使用这个模板。我必须在这里对来自digitalraindrops. 我已经重写了这篇文章，以适应我的需要，目前写这篇文章是为了适应214年的主题。
您可以在上面给出的链接上查看教程。我喜欢这个模板的地方是它可以重复使用上千次。此模板的作用是，您可以从下拉列表中选择类别。该类别的帖子将显示在该页面上。这是我使用的代码
首先，所有元函数包括每页帖子、订单、页面标题、帖子标题等选项。这些代码将包含在函数中。php或自定义函数文件

现在，您只需创建一个新页面，选择“文章页面”模板，然后发布页面。完成后，将显示Posts元数据库的页面。从中，您可以选择要在该页面上显示的类别。希望这对你有帮助
