how to restrict MIME type before upload?!

ProgerXP commented 3 years ago

See examples in filedropjs.org. MIME type is accessible via File.type. Or, on the server-side, use PHP's $_FILES['upload']['type'] or mime_content_type().

However, MIME checks are generally unreliable both client- and server-side. It's better to check file's actual contents using Fileinfo (PHP), gd, etc..
