what's wrong with the upload code?

<?php
    //set where you want to store files
    //in this example we keep file in folder upload
    //$HTTP_POST_FILES['ufile']['name']; = upload file name
    //for example upload file name cartoon.gif . $path will be upload/cartoon.gif
    $path= "upload/".$HTTP_POST_FILES['ufile']['name'];
    if($ufile !=none) {
        if(copy($HTTP_POST_FILES['ufile']['tmp_name'], $path)) {
            echo "Successful<BR/>";
            //$HTTP_POST_FILES['ufile']['name'] = file name
            //$HTTP_POST_FILES['ufile']['size'] = file size
  开发者_C百科          //$HTTP_POST_FILES['ufile']['type'] = type of file
            echo "File Name :".$HTTP_POST_FILES['ufile']['name']."<BR/>";
            echo "File Size :".$HTTP_POST_FILES['ufile']['size']."<BR/>";
            echo "File Type :".$HTTP_POST_FILES['ufile']['type']."<BR/>";
            echo "<img src="$path" width="150" height="150">";
        } else {
            echo "Error";
        }
    }
?>

it is an toturial form here http://tutorialblog.info/2010/08/06/php-upload-single-file.html when i tried in my local environment. it displays an error? what's wrong with the code? thank you.

first, i think this is wrong. if($ufile !=none) it should be if($_POST['ufile' !=none) am i right?

I agree with Stephen, this is not a good example, you also need to validate your upload. you are not going to allow anyone to upload anything.

but if you want just find the issues: well HTTP_POST_FILES is no longer accepted by PHP newer versions. should be $_FILES

$ufile !=none can be if ($_FILES['ufile']['tmp_name'])

copy($HTTP_POST_FILES['ufile']['tmp_name'], $path) better be move_uploaded_file($_FILES['ufile']['tmp_name'], $path)

Your html form enctype should be enctype="multipart/form-data"

the $path path should have the right permission
