Question

我是网站编程的新手。这是我学校“今年年底”的项目。我需要知道如何制作upvote/downvote系统。我设法为每个帖子制作了+1和-1按钮，但是当我希望它们在点击时消失时，所有这些按钮都消失了（而不仅仅是特定的按钮）。 +1和-1适用于个别帖子但我的解决方案不起作用。示例：当我点击帖子+1上的id=2按钮时，所有+1按钮都会消失，依此类推。我想知道我的问题的解决方案。提前致谢

while ($forum = $vysledek->fetch_assoc())
    { 
        if (isset($_SESSION['upvote'])) {
            $type = 'hidden';
        }
        else
        {
            $type = 'button';
        }
         if (isset($_SESSION['downvote'])) {
            $type1 = 'hidden';
        }
        else
        {
            $type1 = 'button';
        }

        ?>

<a href='votes.php?pris=<?php echo $forum['id_prispevek'] ?> & ad_id=1'>
    <input type="<?php echo $type ?>" value="+1"></a>
<a href='votes.php?pris=<?php echo $forum['id_prispevek'] ?> & ad_id=0'>
    <input type="<?php echo $type1 ?>" value="-1"></a>

}

和votes.php

<?php
  include "pripojeni1.php";
 $var_value = $_GET['ad_id'];
 $prispevek = $_GET['pris'];

if ($var_value == 1) {
 $query = mysqli_query($link,"
UPDATE forum 
  SET votes = votes + 1
   WHERE id_prispevek = '".$prispevek."'
 ");
   header("location:vypisForum.php?var=$prispevek");
   $_SESSION['upvote'] = 1;
 unset($_SESSION['downvote']);



  }
 if ($var_value == 0) {
 $query = mysqli_query($link,"
   UPDATE forum 
     SET votes = votes - 1
  WHERE id_prispevek = '".$prispevek."'
 ");
     header("location:vypisForum.php?var=$prispevek"); 
    $_SESSION['downvote'] = 1;
    unset($_SESSION['upvote']);
 }
 ?>
