    File Submission

    Asked by Paul on June 19, 2012 at 12:08 PM

    Hey guys,

    Great idea for a site. I'm thinking about using your service for a TV casting website I'm creating and I want my users to upload casting videos of themselves, I want to limit the file types to .mov, .avi and .mp4. But when I do this in the template and try to test it on my local site it doesn't appear to recognise the file type even though I'm adding .avi, .mov, .mp4 files.

    I wonder if there's a particular syntax that needs to be used. I've attached a screen shot.

    I have checked your form and I found that your extensions are not correct. Try to change your extensions like this: 

    From: .avi .mov .mp4

    To: avi, mov, mp4

    This solve the problem of your upload field.

    Hope this help and if you need further assistance, please don't hesitate to contact us again anytime.

    Thank you!
