如何在php分页中将url变量传递给下一页

Question

我正在尝试通过链接从 URL 中获取值

例如 $id =5;

<a href="ifsc-bank.php?id=<?=$id?>">link 1</a>

我有大约 50 个喜欢的链接列表

link 1 
link 2
link 3
.
.
link 50

当链接被点击时，它将路由到 ifsc-bank.php 并在 ifsc-bank.php 中使用 $_GET 获取值

$id=$_GET['id'];
$query = "SELECT * FROM distdb WHERE BANK_ID = '$id'";

在输出中

    1 record 
    2 record2
    3 record3

`First 1 2 3 Next` is my pagination 

当我单击 1 时，它会显示 id = $id 的相关记录 但是在点击 2 时它没有显示任何记录。

我不明白为什么过滤器在其他页面中不起作用

听到是我的密码

<?php 

 include('dbconfig.inc.php');
        $id=$_GET['id'];

        $query = "SELECT * FROM distdb WHERE BANK_ID = '$id'";       
        $records_per_page=10;
        $newquery = $paginate->paging($query,$records_per_page);
        $paginate->dataview($newquery);
        $paginate->paginglink($query,$records_per_page);
        ?>

分页

<?php

class paginate

    private $db;

    function __construct($dbh)
    {
        $this->db = $dbh;

        $stmt->execute();

Answer 1

得到答案我需要在 Html 开始之前放置代码

<?php
if (isset($_GET["id"]))
    {   
        $_SESSION['page']=$_GET["id"];
        $page = $_SESSION['page'];
    }
else
{
    $page = $_SESSION['page'];
    $tableName = $page."r"; 
}

?>
