Symfony2 Form - File Type validation (mimeTypes) for HTM / HTML

Question

I have a form where I am uploading a file. I would like to validate if the file is in HTM/HTML format.

Is there an existing mimeType for HTM files in symfony?

Thank you.

You can add a validation constraint for the MIME-type of the upload in your FormType :

'file' => new File( array(
    'maxSize' => '20M',
    'mimeTypes' => array("text/html")
));
