mime type validation in laravel 4 doesn't work

Question

I'm trying to validate the file size and the mime type of an uploaded file (mp3 file) in laravel. But the validation only seem to kick in when I upload an image (gif, png). When I upload an mkv file with a size of 100Mb the validation seems to be ok with it. Here's my current code:

$file = Input::file('audio_file');
$file_rules = array('audio_file' => 'size:5242880|mimes:mp3'); //also tried mpeg

$file_validator = Validator::make(Input::file(), $file_rules);

if($file_validator->fails()){
 //return validation errors
}else{
 //always goes here and succeeds
}

Any ideas what's wrong with my code? Thanks in advance!

Try changing the file rules line to:

$file_rules = array('audio_file' => 'size:5242880|mimes:audio/mpeg,audio/mp3,audio/mpeg3');

According to this, 'audio/mpeg' is the correct MIME type for mp3 files (some browsers also use 'audio/mpeg3' or 'audio/mp3').

If that doesn't work, you could get the MIME type before validation:

$file = Input::file('audio_file');
$mimeType = $file->getMimeType();
$supportedTypes = ['audio/mpeg', 'audio/mpeg3', 'audio/mp3'];

if (in_array($mimeType, $supportedTypes)) {
    // validate or simply check the file size here
} else {
    // do some other stuff
}
