    is it possible to restrict file section for a new media type based on extension?

    hey out there,

    i was trying to figure out if there's a way to restrict the type of a file a new 'media type' can upload? i know you can globally enable or disable file extensions but i was wondering if there's a way to say:

    my new media type with the alias of 'MP4File' can only upload files with an 'mp4' file extension.

    be interested to know!

    cheers,

    jake

    Never tried it, but you might be able to hook into Media Service saving event to add some custom logic:

    Most events allow you to cancel the action based on your own logic.

    i think you're onto something there dan...

    just ran this up and it seems pretty happy:

    void MediaServiceSaved(IMediaService sender, SaveEventArgs<IMedia> e)
{
    foreach (var mediaItem in e.SavedEntities)
    {
        if (mediaItem.ContentType.Alias == "MP4File" && mediaItem.GetValue<string>("umbracoExtension") != "mp4")
        {
            e.CancelOperation(new EventMessage("Media", "Please upload a MP4 file", EventMessageType.Warning));
        }
    }
}

    the file still gets uploaded and in this example it's huge mp4 files which is a bit of a pain....

    ...but as a simple file extension check, this works a treat ;)

    i guess there's only so many times the user will sit and wait for a 1gb video file to upload and then be told it's in the wrong format?!

    thank you for the suggestion,

    cheers,

    Don't you mean: ... && mediaItem.GetValue<string>("umbracoExtension") != "mp4") ?
