我在用户个人资料中有一个分页。

当我在测试配置文件中时，URL 是 profile.php?uid=1

但现在我想使用分页从 SQL 数据库中获取信息。当我在另一个页面上尝试分页时，它工作正常，但正如您所知，分页更改 URL 取决于您在哪一边。

所以我的问题是分页将我的 profile.php?uid=1 更改为 profile.php?page=2

您对如何解决该错误有任何提示吗？

这是我的分页代码。

/*pagination */ 
    $per_page = 5;
    //$pages_query = mysql_query("SELECT COUNT('user_id') FROM users");

    $pages_query = mysql_query("SELECT COUNT('file_name') FROM users WHERE  `user_name` = '{$_SESSION['username']}' ") or die(mysql_error()); 
    $pages = ceil(mysql_result($pages_query, 0) /$per_page);

    $page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
    $start = ($page - 1) * $per_page;

    <?php  
 $data = mysql_query("SELECT * FROM users LIMIT $start, $per_page")
 or die(mysql_error()); 
 echo "<table border cellpadding=1>"; 
 while($info = mysql_fetch_array( $data )) 
    { ?><?php
        echo "<tr>"; 
//      echo "<td>".$info['user_id'] . "</td> "; 
        echo "<td>".$info['user_name'] . "</td> ";
    //  echo "<td>".$info['file_name'] . "</td> ";
        ?>
        <td> <a href="download.php?user_id=<?php echo $info['user_id'];?>"> <?php echo $info['file_name']; ?></a></td>
        <?php
        echo "<td>".date('d/m/Y') . "</td>" ;


    }
        echo "</tr>";
        echo "</table>"; 


 if($pages >= 1 && $page <=$pages){

 for ($x = 1; $x<=$pages; $x++){ 

 echo ($x == $page) ? '<strong><a href="?page='.$x.'">' .$x. '</a> </strong>' : '<a href="?page=' .$x. '">' .$x. ' </a> ';

 }

 }

 ?>

/*分页*/

和简介

函数 fetch_user_info($uid){ $uid = (int)$uid;

    $sql = "SELECT
    `user_name` AS `username`,
    `user_email` AS `email`
FROM `users`
WHERE `user_id` = {$uid} ";

$result = mysql_query($sql);

return mysql_fetch_assoc($result);

}

 $data = mysql_query("SELECT * FROM users") or die(mysql_error()); 

$files = mysql_query("SELECT `file_name` FROM users WHERE  `user_name` = '{$_SESSION['username']}' ") or die(mysql_error()); 
$user_info = fetch_user_info($_GET['uid']);

我真的不知道如何解决这个问题=/

看起来您没有在寻呼机链接中传递用户 ID，请尝试更改此行...

echo ($x == $page) ? '<strong><a href="?page='.$x.'">' .$x. '</a> </strong>' : '<a href="?page=' .$x. '">' .$x. ' </a> ';

到

echo ($x == $page) ? '<strong><a href="?uid='.$_GET['uid'].'&page='.$x.'">' .$x. '</a> </strong>' : '<a href="?uid='.$_GET['uid'].'&page=' .$x. '">' .$x. ' </a> ';

你有uid会议吗？

尝试

echo ($x == $page) ? '<strong><a href="?page='.$x.'">' .$x. '</a> </strong>' : '<a href="?user_id=' . $_SESSION['uid'] . '&page=' .$x. '">' .$x. ' </a> ';

但是，实际上，如果您为您的uid. 你可以改变fetch_user_info 

function fetch_user_info(){ 

    $sql = "SELECT
    `user_name` AS `username`,
    `user_email` AS `email`
FROM `users`
WHERE `user_id` = " . $_SESSION['uid'];

$result = mysql_query($sql);

return mysql_fetch_assoc($result);

}

错字：

    $page = (isset($_REQUEST['page'])) ? 1 : $_REQUEST['page'];

变成

    $page = (!isset($_REQUEST['page'])) ? 1 : $_REQUEST['page'];

这是一个非常简单的解决方案。您基本上“读取”分页代码中的 URL/查询字符串并自动“将其附加到您的 URL。我为您编写了一些简单的即插即用代码 - 这很容易做到这一点（您只需要多一行代码和一个包含文件 - 'inc_pagination.php'， - 到需要分页的任何页面。不修改现有代码）：

/*pagination */  
$per_page = 5; 
include 'inc_pagination.php'; /* FIRST LINE ADDED TO YOUR CODE*/

$pages_query = mysql_query("SELECT COUNT('file_name') FROM users WHERE  `user_name` = '{$_SESSION['username']}' ") or die(mysql_error());  
$pages = ceil(mysql_result($pages_query, 0) /$per_page); 

/* REMOVING THESE TWO LINES */
/*  $page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1; 
    $start = ($page - 1) * $per_page; */

$data = mysql_query("SELECT * FROM users LIMIT $start, $per_page") or die(mysql_error());         
echo "<table border cellpadding=1>";                                    
while($info = mysql_fetch_array( $data ))                                    
{ ?><?php                                   
    echo "<tr>";                                    
    echo "<td>".$info['user_name'] . "</td> ";                                   
    ?>                                   
    <td> <a href="download.php?user_id=<?php echo $info['user_id'];?>"> <?php echo $info['file_name']; ?></a></td>                                   
    <?php                                   
    echo "<td>".date('d/m/Y') . "</td>" ;                                   

}                                   
    echo "</tr>";                                   
    echo "</table>";    

/* 2nd LINE ADDED (Replaces Existing Page Code) - Add this wherever you need page numbers displayed */
echo paginate_me(ceil(mysql_result($pages_query, 0)/$per_page), $per_page);

请注意，您显然需要删除现有的分页代码块：

if($pages >= 1 && $page <=$pages){                      

   for ($x = 1; $x<=$pages; $x++){                       
      echo ($x == $page) ? '<strong><a href="?page='.$x.'">' .$x. '</a> </strong>' : '<a href="?page=' .$x. '">' .$x. ' </a> ';                      
   }                      

}

最后是包含文件'inc_pagination.php'的代码。请注意，这个具有所有的花里胡哨 - 包括用于悬停/鼠标悬停和其他视觉效果的 javascript - 如果您愿意，我还可以包括一个非常简单的纯文本版本！
