我想根据表单提交中的隐藏值更改上传目录。
正如你所看到的，我在表单上提交了一个move_uploaded_file之后的POST，但如果我添加目录位置，它将无法上传。在此之前，目录已创建为POST值。谢谢
<?php
session_start();
if($_SESSION['myusername'] == 'admin')
{
$header = 'headeradmin.php';
}
elseif (!empty($_SESSION['myusername']))
{
$header = 'header.php';
}
else
{header("location:../../login");}
require_once '../../connect.php';
$loggedin= $_SESSION['myusername'];
$result = mysql_query("SELECT * FROM login");
if (!$result) { // add this check.
die('Invalid query: ' . mysql_error());
}
$id = $_GET['id'];
?>

这就是表单重定向的地方，我现在已经删除了回声，但它似乎不起作用。
<?php
if($_SERVER['REQUEST_METHOD'] == "POST"){
if(move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_POST['username'] . '/' .$_FILES['file']['name'])){
echo($_POST['index']);
}
exit;
}
?>
首先，这些代码不是很安全。用户可以在那里写任何东西。其次，不要在函数中使用echo。只有$_POST['username']。
您需要删除回波
if(move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_POST['username'] . '/' .$_FILES['file']['name'])){
我还建议不要使用$_POST['username']，而是使用$_SESSION['username']，除非我遗漏了什么，并且您允许用户将文件上传到其他用户目录
