分享 link 个页面

Question

我正在分享 link 来自用户个人资料的事件，事件页面是动态的，当用户点击分享到 Facebook 时，我获取事件 ID 并将其存储到 Session 变量中，然后我我在事件页面中使用此会话变量来描述：og 标签。但是我的：og 标签没有显示数据。这是我的代码：

    function post(id) {
        document.cookie = "eventID = "+id;
        <?php $_SESSION['EVENT_ID'] = $_COOKIE['eventID']; ?>;
        FB.ui({
               method: 'share',
               href: "mywebsiteURL/events.php"
           }
     }
//Here is the head of my events.php
    $col = 'events.*,status.name as statusName,mosque_reg.name as mosque';
    $table = "events,status,mosque_reg";
    $where = "events.id = '".$obj->verifyint($_SESSION['EVENT_ID'])."' AND events.status_id = status.id 
    AND events.inserted_by = mosque_reg.inserted_by"; 
    $ticket = $obj->read_specific_event($col,$table,$where);
    if($ticket->num_rows>0)
    {
     $issue = $ticket->fetch_assoc();
     $pic ="https://www.theglobalmuslim.com/mosque/portal/images/events/".$issue['photo'];
     $contactName = $issue['contactPerson'];
     $contact = $issue['contactNumber'];
     $description = $issue['description'];
     $topic = $issue['topic'];
  }
  ?>
   <meta property="fb:app_id" content="258374655358948" />
   <meta property="og:site_name" content="The Global Muslim"/>
   <link property="og:url"           content="https://www.theglobalmuslim.com/events.php?id=<?php echo 
   $_SESSION['EVENT_ID']; ?>"/>
   <meta property="og:type"          content="website" />
   <meta property="og:title"         content="Event Name:<?php echo $topic; ?>" />
   <meta property="og:description"   content="New event is held at Mosque <?php echo 
   $issue['mosque']."\n."." Description: ".$description ?>" />
   <meta property="og:image"         content="<?php echo $pic; ?>" />

Answer 1

我通过打开内部页面的 URL 解决了这个问题，他们我使用 GET 方法在 :og 标签中显示事件信息。
