How to output part of feild using mysql and php

Hi all. i got a huge list of mp3 that they are in diffrent folders. I put all the songs infor in mysql database in a table called files. I want a query db that output foldernames for me .The folder name is part of feiled called filename in files table. The value of filename is like this stored in db :

http://localhost/wimpy5recursive/mp3s/album1/song1.mp3
http://localhost/wimpy5recursive/mp3s/album2/song4.mp3
where the bold part is the foldername. i want to print folder name.Note:mp3s is the root folder for mp3s.The whole point is to list all folders name and link to page that holds songs inside those folders.

Furthermore, i want a query all feilds info for songs in each given folder.What i mean is that for each folder it lists all songs info iside that folder.I want to be able to tell the query what folder i want to list its song.Thanks

we arent gunna do it for you.

Not sure what your looking for... heres somthing i used to display mp3s from a Dir i would pass via url.com?folder=foldername

PHP Code:

---

if ($handle = opendir($_GET['folder'])) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
            if (preg_match('#^(.+).mp3$#', $file, $match)){
                    $files[] = $file;
                } else {
                    $dirs[] = $file;
                }
        }
    }
    
    closedir($handle);
    
    if (count($dirs) != 0) {
        sort($dirs);
        //echo "".$dirs[];
    }
    if (count($files) != 0) {
        sort($files);
    }
}

echo "Sub Folders<hr align='left' width='74%'>" ;
for ($i = 0; $i < count($dirs); $i++) {
    echo "<a href='?folder=".$_GET['folder']."/".$dirs[$i]."'>".$dirs[$i]."</a><br />" ;
}

echo "<h2><hr align='left' width='52%'>".$_GET['folder']." (".count($files).")<hr align='left' width='52%'></h2>";

for ($i = 0; $i < count($files); $i++) {
    $date = date("M j Y",filectime($_GET['folder']."/".$files[$i])) ;
    $size = formatsize(filesize($_GET['folder']."/".$files[$i])) ;
    echo $date." &nbsp; <a href='".$_GET['folder']."/".$files[$i]."'>".$files[$i]."</a> - ".$size."<br />" ;
}

AGREE WITH PlaGuE!
NEXT TIME U HAVE A PROBLEM LIKE THIS U´LL LOSE LESS TIME THINKING.
IT CAN BE MADE BY THE MYSQL SERVER WHITH FUNCTIONS OR DOIT YOUR SELF IN CODE.

That is not a very safe peice of code to use as you could supply the path to any directoy on the server in the URL.

That crossed my mind, but the idea was to list off all mp3s in the dirs with cleaner details then just opening up the dirs for browsing. By limiting what files can be displayed with preg_match, would you still say its unsafe (with the intent i stated) ?

Thanks for your input.

I guess that depends upon whether you mind people searching for mp3 files elsewhere on your server.
