Set mime_types not working for zip file in Symfony

Question

In my Symfony application, I want to set zip file as one of the mime type during the file upload, the code to do this is below:

    $this->validatorSchema ['Documents'] = new sfValidatorFile ( 
        array ('mime_types' => array(
        'application/zip', 
        'image/jpeg',
    'image/pjpeg',
    'image/png',
    'image/x-png',
   'image/gif',
        'application/x-zip',
        'application/octet-stream',
        'application/pdf') ), 
        array ('invalid' => 'Invalid file.',
         'required' => 'Select a file to upload.', 
         'mime_types' => 'The file must be of JPEG, PNG , GIF, pdf and zip format.' ) );

However, when I did the uploads, I found that all of pdf, png, gif etc can be uploaded. The only mime type that cannot be uploaded, are files that end with .zip.

What's going wrong here?

I asked a related, but different question here.

Note: I am using Symfony 1.2.7

Edit: I did some further testing with different browsers. Firefox 3 works because of 'application/octet-stream'', whereas IE works because of 'application/x-zip-compressed', Google Chrome doesn't work at all.

Answer 1

After more testing, I believe that this is a bug in Symfony.
