如何返回具有唯一id的页面



在处理数据后，我在返回具有唯一id的页面时遇到问题

代码的第一部分重定向到页面，获取文件夹的唯一id

<a href="folder.php?fldid=<?= $row['id'] ?>"><img src="<?= $row['folderimage'];?>" onerror="this.src='images/folder.png'"  class="card-img-top"  height="160" ></a>
<div class="card-img">
<h6 style="text-align: center;"><?= $row['foldername'];?></h6>

这是具有唯一id 的folder.php

<?php
require'config.php';
session_start();
if(isset($_GET['fldid'])){
$folder_id=$_GET['fldid'];
$sql="SELECT * FROM file_folder WHERE id='$folder_id'";
$result=mysqli_query($conn,$sql);
$row=mysqli_fetch_array($result);
$folder_name=$row['foldername'];
}
?>

下面的代码是我的问题，我不知道我应该在标题中添加什么来让我回到具有唯一id 的页面

if(isset($_POST['folderlinkbtn'])){
$fldid = $_POST['folderid'];
$fol = $_POST['fldname'];
$lin = $_POST['link'];
$image='images/'.$_FILES['image']['name'];
$target_dir="images/";
$target_file=$target_dir.basename($_FILES['image']['name']);
move_uploaded_file($_FILES['image']['tmp_name'],$target_file);

$sql="SELECT folder_id FROM folder_link WHERE folder_name ='$fol' LIMIT 1";
$check_query =mysqli_query($conn,$sql);
$count_folder = mysqli_num_rows($check_query);
if($count_folder>0){
$_SESSION['showFilerror']= 'block';
$_SESSION['filemess']="Sorry Folder Name Already Exist";
header('location:folder.php');}
else{
$sql ="INSERT INTO folder_link (folder_id,folder_links,folder_name,folder_image)VALUES('$fldid','$lin','$fol','$target_file')";
$run_query=mysqli_query($conn,$sql);
if($run_query){
$_SESSION['showAlert']= 'block';
$_SESSION['message']="Add File Successful";
header('location:folder.php');
}
else{
$_SESSION['showFilerror']= 'block';
$_SESSION['filemess']="ERROR</strong>";
header('location:folder.php');
}
}
}

如果处理需要重定向到另一个页面，则使用GET方法将唯一ID包含在url中，然后将其包含在php 的头函数中

我已经解决了这个问题，谢谢你给我一个想法，我只是放了

header( "Location: folder.php?fldid={$fldid}" );
