Php WordPress:Follow user按钮在Ajax分页模板中添加时不起作用？

我正在使用一个与Ajax一起工作的插件来创建一个follow按钮，以使我们的用户相互关注

我把follow按钮放在任何需要用户跟随其他用户的地方，比如

echo pwuf\u get\u follow\u unfollow\u链接（//user id here）

我面临的问题是，如果我在任何Ajax分页模板中添加了这个echo函数，无论是后期Ajax分页还是用户列表Ajax分页，下面的按钮都不起作用，并且在单击时找不到用户id

但是，在我将更多内容加载到第二页之前，他肯定可以在第一页找到用户id

e、 g：如果我有一个像这样的Ajax分页，并且试图在这个Ajax分页中回显follow按钮函数，那么它不起作用

add_action('wp_ajax_loadmore_by_ajax', 'loadmore_by_ajax_callback');
add_action('wp_ajax_nopriv_loadmore_by_ajax', 'loadmore_by_ajax_callback');

function loadmore_by_ajax_callback()  {
   //do something

   //echoing follow button
    echo pwuf_get_follow_unfollow_links( //user id here );

}

我将在下面添加我所有的插件代码，我希望得到一些帮助来解决这个问题，谢谢你的时间
