Sorry, there was a problem uploading your file.

Answer 1

If the form is a part of upload.php too, you need to encapsulate the PHP-code and first check if $_FILES is not empty, otherwise you will always get a Notice if you only want to display the form.
<?php
if(!empty($_FILES))
{
//your PHP-code here
}
?>
<!-- your form here -->

Khan sb Place this code in file
called upload.php
create a folder called upload where
you created upload.php
change echo "The file ". basename(
$_FILES['uploadedfile']['name']). "
has been uploaded"; to echo "The
file ". basename(
$_FILES['uploaded']['name']). " has
been uploaded";
This will upload file successfully. First time when upload.php is uploaded there is no file selected so you will see some errors. But after you select a file and click upload you will not see any error. To avoid this error do as suggested by Dr. Molle
