1-为什么此功能未显示在内容底部？
2-为什么我们在内容顶部使用此过滤器，它的显示审阅框位于
分类页面的内容摘要！！

1-为什么此功能未显示在内容底部？
筛选器必须返回内容，而不是echo 内容，但你打电话sandy_reviews() 在筛选器回调中，以及sandy_reviews() 运行时打印内容。您需要重写该函数以返回内容，而不是echo 信息技术
2-为什么我们在内容顶部使用此过滤器，它的显示审阅框位于
分类页面的内容摘要！！
您的类别存档正在使用the_content() 要显示摘要，您的代码不会阻止这一点。您想要的是：
add_filter( \'the_content\', \'sandy_posts_filter\' );
function sandy_posts_filter( $content )
{
if (!is_single()) return $content;
// the rest of your code
