    Validation process

    Asked by niconi on June 30, 2016 at 07:36 AM

    Do you have any advice (tool, app or method), for us to set a validation process of the files uploaded in the form with the customer.


    We think, resending the filled form (saved with the first files uploaded) with an email saying this file or this file is KO.


    Anything better ?

    Yes, it is possible to validate the image as you see below:


    When you click  "Validate Image" toolbar it checks if the uploaded image(jpg,png,gif) are real images.

    Here is how it works:


    In addition to that, with Image Upload Preview widget, the user selects the image they need to upload, a preview of the image is displayed on the form. The form user can choose to discard it and try again, or upload it. If you have any question or issues, please do not hesitate contacting us. We will be glad to assist you.
