我在用户个人资料中加了一个分页。
当我在测试配置文件中时，URL是profile.php？uid = 1
但是现在我想使用分页来从SQL数据库中获取信息。 当我在另一个页面上尝试分页时，它可以正常工作，但正如您所知，分页更改后，URL取决于您的分支。
所以我的问题是分页改变了我的profile.php？uid = 1到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. '">' .$x. ' </a> ';
}
}
?>
/ *分页* /
和个人资料
function fetch_user_info（$ 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. '">' .$x. ' </a> ';
答案 1 :(得分：0)
会话中有uid吗？
试
echo ($x == $page) ? '<strong><a href="?page='.$x.'">' .$x. '</a> </strong>' : '<a href="?user_id=' . $_SESSION['uid'] . '&page=' .$x. '">' .$x. ' </a> ';
但是，如果您为uid添加会话，实际上并不需要它。您可以更改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);
}

<强>错字：
$page = (isset($_REQUEST['page'])) ? 1 : $_REQUEST['page'];
已更改为
$page = (!isset($_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 - 这将很容易实现（所有您需要的只是1个额外的行代码和一个包含文件 - 'inc_pagination.php'， - 到任何需要分页的页面。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), $per_page);
请注意，您需要明显删除现有的分页代码块：
if($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> ';
}
}
最后这里是包含文件'inc_pagination.php'的代码。请注意，这个有所有的花里胡哨 - 包括用于悬停/鼠标悬停的javascript和其他视觉效果 - 如果你愿意，我还可以包含一个非常简单的文本版本！
