Question

我有以下代码

<form enctype="multipart/form-data" action="upload.php" method="POST">
 Please choose a file: <input name="uploaded" type="file" /><br />
 <input type="submit" value="Upload" />
 </form>  

<?php 
 $target = "upload/"; 
 $target = $target . basename( $_FILES['uploaded']['name']) ; 
 $ok=1; 
 if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) 
 {
 echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";
 } 
 else {
 echo "Sorry, there was a problem uploading your file.";
 }
 ?>

我的页面位于http://local.host/nausal/upload.php

现在我遇到了以下错误，虽然我在网站上创建了一个名为upload的文件夹。

注意：未定义的索引：在第15行的C：\ wamp \ www \ Nausal \ upload.php上传

注意：未定义的索引：在第17行的C：\ wamp \ www \ Nausal \ upload.php上传   抱歉，上传文件时出现问题。

Answer 1

如果表单也是upload.php的一部分，则需要封装PHP代码并首先检查$ _FILES是否为空，否则如果您只想显示表单，则总会收到通知。 / p>

<?php
  if(!empty($_FILES))
  {
        //your PHP-code here
  }
?>
<!-- your form here -->

Khan sb将此代码放入文件中叫上传.php
创建一个名为upload的文件夹你创建了upload.php
将echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";更改为echo "The file ". basename( $_FILES['uploaded']['name']). " has been uploaded";

这将成功上传文件。第一次上传upload.php时，没有选择文件，因此您会看到一些错误。但是在选择文件并单击上载后，您将看不到任何错误。为了避免这种错误，请按照Molle博士的建议进行。

我无法将文件上传到php中的本地主机文件夹
