PHP upload script og formstruktur

Hejsa, jeg er ved at klampe en upload funktion sammen til en webapp, men får disse her når jeg forsøger at uploade et billede:



Notice: Undefined index: temp_name in /var/www/vhosts/band.com/httpdocs/tryingcode.php on line 31



Notice: Undefined index: temp_name in /var/www/vhosts/band.com/httpdocs/tryingcode.php on line 35

There was an error uploading the file, please try again.



Scriptet:





ini_set('display_errors', ON);

error_reporting(E_ALL);



if (!isset($_POST['upload']))

{

echo "



Choose a file to upload:




";

}

else

{

//

// path to the folder where the file is going to be placed in the end.

//

$target_path = "music_files/media_files/";

/* We add the original filename to the end of our target path.

Result is "/music_files/media_files/"filename".extension" */

$target_path = $target_path . basename($_FILES['uploadedfile']['name']);

//

// We decide what the temporay location of the uploaded file is..."

//

$_FILES['uploadedfile']['temp_name'];

//

//We attempt moving the file from the temporary location to the final location.

//

if(move_uploaded_file($_FILES['uploadedfile']['temp_name'], $target_path))

{

die("The file ". basename($_FILES['uploadedfile']['name']). " has been uploaded.");

}

else

{

die("There was an error uploading the file, please try again.");

}

}



Og derudover: Hvordan indarbejder man en uploadform i en eksisterende form uden at konflikte med W3C's standarder?



Hejsa.
