MP3 Uploader

[RaythMistwalker]

Ok heres the deal:

 

ATM I am using SAM Broadcaster as an AutoDJ and LiveDJ. Due to me only holding certain songs on my computer i wish to allow users to add songs manually but only if they are in mp3.

 

Features

---

Upload the mp3 to directory

md5 the file name so there is no spaces

(IF POSSIBLE) get the ID3 info from the File for Artist and Title and save them in variables

^--- If thats not possible i will add Artist - Title to my form.

 

 

This has to work with ONLY mp3. All i really need is the php form for the upload- i can write the form easily myself.

 

Could someone possibly write a quick code or point me in direction of a tutorial as i have never done php uploading before.

 

Thanks in advance

There are many tutorials and ready-made scripts to process file uploads.  A simple Google search will get you all you need. There are two methods to validate that a file is of the correct type. You can simply check the extension of the file to ensure it is ".mp3" (make sure to use strtolower()!) and/or you can also detect the file properties to ensure it is an mp3 (lest somebody simply renames the file extension to mp3). That would be done using finfo_file().

 

As for the ID3 MetaData you could use the class getID3(), which will read all ID3 tags for the file. http://getid3.sourceforge.net/

Ok turns out i dunno howto do the form.

What wuold i use for a user to select the file from their computer?

[Psycho]

What does the code you posted have to do with your question? I see no form in that code - where is that code?

 

When I typed in "form file upload" into Google, the second result was "PHP Tutorial - File Upload": http://www.tizag.com/phpT/fileupload.php

Wait, a tutorial on doing file uploads with PHP, sounds interesting. Maybe you should give that a read.

 

EDIT: I just completely rewrote this entire post. I had a lot of condescending and belittling statements. Although I think you may be worthy of such treatment I am trying to refrain from such commentary.

Ok then heres the 2 codes im using:

 

upload.php (ie the form)

<form enctype="multipart/form-data" action="songupload.php" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="6920600" />
Choose a mp3 file to upload: <input name="uploadedfile" type="file" /><br />
Enter Song Artist: <input name="songartist" type="text"><br>
Enter Song Title: <input name="songtitle" type="text"><br>
<input type="submit" value="Upload Song" />
</form>

 

songupload.php (uploader - found this one a website)
