<form class="form-horizontal" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST" enctype="multipart/form-data"> 
    <div class="panel-body no-padding">
<?php
    $hostname = "localhost";
    $username = "root";
    $password = "";
    $mysql_database = "Dummy";
    $connect_mysql = mysql_connect($hostname, $username, $password);
    $mysql_db = mysql_select_db($mysql_database, $connect_mysql);
    $query = mysql_query("Select * from User");
?>
    <table class="table table-striped">
        <thead>
            <tr class="warning">                
                <th>Banner Image</th>
                <th>BannerId</th>               
            </tr>

               <td>
                  <?php
                       $db = mysqli_connect("localhost", "root", "", "Dummy");
                       $sql = "SELECT Images from Users WHERE UserID='$UserID'";
                       $sth = $db->query($sql);
                       $res2 = mysqli_fetch_array($sth);
                       echo '<img src="data:image/jpeg;base64,' . base64_encode($res2['Images']) . '" width="150px" />';
                   ?>              
              </td>
              <td><?php echo $data['BannerId'] ?></td>
              <td> <input type="file" name="file1"> </td>
              <td><div style="margin-right:20px;">
                    <input type="submit" value="<?php echo $bannerid ?>"  class="btn-success btn" name="Update">
<!--                <a href="form1.php?Update=<?php echo $UserID?>"><button class="btn-success btn">ADD</button></a> &nbsp;-->
<!--                <a href="form1.php?delete=<?php echo $UserID?>"> <button class="btn-success btn">DELETE</button></a></div></td>   -->
           </tr>
           <?php }?>    
        </tbody>
    </table>                           
 </div>
 </form>

此代码仅适用于最后一位用户，当我尝试编辑其他用户时，它正在为我提供不支持的文件格式
