PHP分页不会更改页面上的值

我使用了php分页教程：。正如它所说的，这很容易，我没想到会有任何问题。然而，我遇到了一个。现在我知道为了获得最好的结果，您应该看到我的源代码，所以我将提供它。问题是，如果成员是正确的，它可以很好地查询，并且只在页面上显示某些数据，并将其限制为每页仅显示几个数据。。。但是，当我尝试更改以在下一页上看到更多注释时，它不会更改值

        /*  $dbLink = mysql_connect("localhost", "sco0100_james", "creeper");
            mysql_query("SET character_set_results=utf8", $dbLink);

您的SQL查询应该包含一个TOP和一个LIMIT值，以便您选择所需的范围（页面）。类似于此：

$items_per_page = 10;
$query = "SELECT TOP $items_per_page * FROM table LIMIT ". $items_per_page * $REQUEST['page'];

是，
$targetpage
不正确：

 $targetpage = "profile.php?id=$id";

将生成类似于
profile.php？id=42的内容。然后在URL中使用该字符串：

 <a href=\"$targetpage?page=$counter etc..." />

$limit是“我的代码”中的每页项目数变量。这显示在$sql查询中。但我现在要改变一下，看看会发生什么，谢谢。这会在调用它的代码中产生一个错误。错误为：警告：mysql\u fetch\u array（）：提供的参数不是有效的mysql结果资源。这是我将其更改为：$sql=“SELECT TOP$limit*FROM$tbl_name WHERE member2=”“$id.”“ORDER BY id ASC limit”$限额*$REQUEST[“页面”]；阿里加托。这已经奏效了。^嗯。。。就我现在看来，它已经奏效了。如果我以后发现它做错了什么，我会发回的
 <a href="profile.php?id=42?page=XXX" />

 <a href=\"$targetpage&page=$counter etc..." />
                      ^--- &, not ?
