当我按下编辑时，所有信息都在那里，点击更新后，错误将显示（如图所示）它已经获得了ID，因为如果没有，它将不会显示信息。并且它不保存我的更新，我更改了信息，但点击按钮后信息仍然相同。

Information

Answer 1

试试这个，替换：

  $query=mysqli_query($dbcon,"select * from users_tbl where id 
='$get_id'")or die(mysqli_error());

到

  $query=mysqli_query($dbcon,"select * from users_tbl where id 
=$get_id")or die(mysqli_error());

删除单引号。它没有取代它的价值。

如果这对你有用，请告诉我。

Answer 2

你应该检查，是否返回结果或没有。如果您的数据库中没有正确的ID，则可能出现此错误。

  <section id="kalender" class="kalender-section content-section text-center">
    <div class="container">
        <div class="row">
             <div class="col-lg-4 col-lg-push-8 mx-auto">
              B
             </div>
             <div class="col-lg-8 col-lg-push-4 mx-auto">
              A
             </div>
        </div>
    </div>
 </section>

PS：花时间学习准备好的陈述。并且不要使用将参数传递给SQL查询的方式。在这种情况下，执行SQL注入非常容易。
