Uploading audio mp3 files.

T_Hayden

I have a form for uploading audio files. I have made the validation only allow real audio, wma, mp3 files. the real audio and wma files work fine but when i try to upload the mp3 file it doesnt work. I am not completely sure what all the MIME types are for mp3 files but i have tried a few that i have found and the do not work. Here is my code:

if (!empty($_FILES['sermon']['type'])){
		$extension = "";
		if($_FILES['sermon']['type'] == "audio/x-ms-wma"){ $extension = "wma"; }
		elseif($_FILES['sermon']['type'] == "audio/x-pn-realaudio"){ $extension = "ra"; }
		elseif($_FILES['sermon']['type'] == "audio/x-mp3"){ $extension = "mp3"; }
		else{
			$errors['sermon'] = "Your file is not a supported format. Please upload .wma, .mp3, and .ra files 

only!";

}
	$filename = $filename . "." . $extension;
	$serverpath = $dirToSaveIn . "/" . $filename;
	echo "filename: " . $filename . "<br>";
	echo "serverpath: " . $serverpath. "<br>";
	$webpath = $webpath . $filename;
	$move_result = move_uploaded_file($_FILES['sermon']['tmp_name'], $serverpath);
}

its audio/mpeg for mp3 files.
the other thing about this, is that it cant necessarily be trusted because it can be spoofed. make sure the extensions are proper, because even if someone uploads a php script with an mp3 extension, it cant be executed as php so its safe.

Well I'm pretty new to this so might i ask how that can be done?

also... I have tried multiple MIME types....mpeg didnt work either, x-mp3 was just the last one used.

hm well audio/mpeg is what mp3 files are identified as in the browser, a header Content-Type: audio/mpeg is sent wit the uploaded file. normally to ensure a file is of the right type you check out the headers, like with a jpeg you can check the first 4 bytes are FF D8 FF E0.
