Now we have file_validate_extensions but extensions can be misleading. Change name from *.bmp to *.png and Windows will show it all right, many browsers too. Similar for zip and self extracting exe. So it would make sence to have easily applied list of allowed MIME types, like:

'my_archive' => array(
  '#type' => 'managed_file',
  '#upload_validators' => array(
    'file_validate_extensions' => array('zip'),
    'file_validate_mimetypes' => array('application/zip')
    'file_validate_size' => array(MAX_FILE_SIZE),
  ),
);

And maybe, just maybe, quick check if extension matches MIME type too, but that would be just a bonus - most fields only need one mimetype and one or two extensons anyway. Detecting PNG missnamed as JPG would be neat, but not crucial.

This functionality should be added to node's fields as well, not only to forms api.

    Thank you for sharing your idea for improving Drupal.

    We are working to decide if this proposal meets the Criteria for evaluating proposed changes. There hasn't been any discussion here for over 8 years which suggests that this has either been implemented or there is no community support. Your thoughts on this will allow a decision to be made.

    Since we need more information to move forward with this issue, the status is now Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.

    Thanks!
