PHP File Uploader

Jacotheron

I need a PHP script that can upload music files (mp3). The script is for a home project I have started a while ago. I have a MySQL database of all the music that I have. Other computers on the network should be able to connect to the database and run queries on the database or upload new music that does not yet exist on the database. The uploaded file's name should be in the following format: ARTIST - TITLE.mp3. I have the code to upload images, but have no idea what to change to make it music compatible and correctly rename the file and move it to the correct folder. Here is the code I have:

Please help me to get this script ready for my database. I know how to insert a new entry in the database but that would be done later after the main part do what it should do.

Here's the code snippet to rename the uploaded file to ARTIST - TITLE.mp3 and move it to destination folder.

Expand|Select|Wrap|Line Numbers

 
<?php

/* obtain artist name and title from previous form */

$artist   = $_POST['artist'];

$title    = $_POST['title'];
 
/* new name for the uploaded mp3 */

$filename = "$artist - $title.mp3";
 
/* change to the directory of your mp3s */

$destpath = "C:/www/uploads/mp3";
 
/* move uploaded file to destination path */

if (is_uploaded_file($_FILES['file']['tmp_name'])) {

    move_uploaded_file($_FILES['file']['tmp_name'], "$destpath/$filename");

}

?>

How do I specify that the PHP should create the directory if the directory does not exist. I want all music to also be sorted ARTIST/ALBUM/ARTIST - TITLE.mp3. Every Thing works well when I create the path myself but the script should do it.

Thank you for the help

Have a look at is_dir()

:)

Now I could test if the directory exist, but how do I command PHP to create the directory if it does not exist? That is my biggest problem.

Thank you for the help

  /* and create the directory */

  mkdir($dir, 0700);

When I enter this information, and run it with WAMP, I get the following error message: "Warning: mkdir() [function.mkdir]: No such file or directory in the directory". I have changed the $dir to my variable and it just do not want to create the directory. It seems that it is looking for a function that describes exactly what it should do.
