我正在尝试制作一个包含电影的网站，一切都很好，但我只有一个小问题，每当我制作网站时，我都会在本地计算机上完成所有工作测试然后我上传网络，下面的代码用于带有查询的分页，它在 WAMP（本地）中运行良好。但是当我将分页代码上传到我的网络服务器时，它显示不存在。它显示了其他部分，有什么问题？

<?php

$per_page = 35; 
 $page = 1;
 if (isset($_GET['page'])) 
 {
  $page = intval($_GET['page']); 
  if($page < 1) $page = 1;
}

 $start_from = ($page - 1) * $per_page; 

$con= mysql_connect("localhost","sarya_asad","Thisisfor123");
 mysql_select_db('saryaal_com_movies',$con);

 $current_items = mysql_query( "SELECT * FROM `english` LIMIT $start_from, $per_page");
 if( mysql_num_rows($current_items) > 0)
 {
  while($item = mysql_fetch_assoc($current_items))
  {

  ?>
    <tr>
        <td> <strong><a href="english/english-preview.php?id=<?php echo$item['id']?>" ><?php echo $item['title'] ;?></a>    </strong></td>
        <td> <strong> <?php echo $item['year'] ;?>  </strong></td>
        <td> <strong> <?php echo $item['quality'] ;?>   </strong> </td>
    </tr>
    <tr><td>
    <?php
    }
 }
 else
 {
  echo 'this page does not exists'; 
 }

 $total_rows = mysql_query("SELECT COUNT(*) FROM `english`");
 $total_rows = mysql_fetch_row($total_rows);
 $total_rows = $total_rows[0];

 $total_pages = $total_rows / $per_page;
 $total_pages = ceil($total_pages); # 19/5 = 3.8 ~=~ 4

 for($i = 1; $i  <= $total_pages; ++$i)
 {
  echo "<a href='temp2.php?page=$i' class='pagNumActive'>$i</a> &nbsp;&nbsp;";
 }
 ?>

你可能想使用类似的东西：

$per_page = 35;
$start_from = $page * $per_page - $per_page;

这是你的问题：

$con= mysql_connect("localhost","sarya_asad","Thisisfor123");
    mysql_select_db('saryaal_com_movies',$con);

您需要更改主机详细信息。localhost是您机器上的本地服务器。

改变这个

 $start_from = ($page - 1) * $per_page;

至

 $start_from = ($page) * $per_page;

试试这个分页逻辑：

您的目标是抵消您希望在每页上显示的图像数量。

因此，假设您想在一个页面上显示 6 个电影缩略图……您将拥有：

$videos_per_page = 6
$pageNumber = (isset($_GET['page']) ? ($_GET['page']) : 1);

你的偏移量将是：

$offset = $videos_per_page * $pageNumber

（6 个视频 * 第 0 页...所以您抵消了 0 个视频。这很好，因为您想在第 0 页的数据结构中显示前 6 个视频）。

所以现在您有了偏移值...您需要将数组指针设置到正确的位置...循环遍历存储电影的数据库行并将指针移动您的偏移值...将其存储在 $videos_to_offset 中。 ..

while ($videos_per_page < $offset && ($row = $Query_Result->fetch_assoc())) {
    $videos_to_offset++;
}

现在你可以遍历你的数据库行，从你的偏移数组指针离开的地方输出你的视频：

    $video_counter = 0;
    while ($video_counter < $videos_per_page && ($row = $Query_Result->fetch_assoc())) {

        echo   $row['videopath'];
        $video_counter++;
}

类似的东西。
