问题描述
我正在尝试从 wordpress 的自定义帖子（产品）标题自动生成标签，因此我可以使用这些标签而不是 Jetpack 的共享消息。我希望完成的是一个分享信息，例如“#tag #tag #tag URL”（理想情况下），或者如果第一个太复杂或不可能的话，至少是“标题 URL”。
我的产品帖子是自动创建的，然后立即由 Jetpack 作为 Facebook 的摘录+URL 共享。我试图在代码片段中使用下面的代码，但它破坏了产品页面并且也没有完成它的工作。我还应该提到，这些都不是我的创作，我正在试验 PHP，并且我结合了来自不同文章的 2-3 部分代码。
if ( class_exists( 'Jetpack' ) && Jetpack::is_module_active( 'publicize' ) ) {
