Hi,

I'm trying to figure out how to solve a problem. I'm developping a website running a contest. Users (already registered) are asked to upload a file to participate. Each registered user can only upload one file.

The question is: How to disallow the file upload feature (component) for a registered user that has already sent a file?

Thanks!

Hello,

There are several ways to achieve this:

1'st way:

- you can use a "unique filed" validation rule for your email field, thus the form can only be submitted once using that email address. More information about this validation rules can be found here:

- make the file upload component of your form required, so that users that submit the form are forced to upload a file.

2'nd way:

- would be to use a script in the "Scripts called on form process" that will check if the uploaded file exists in the database or not. More information about the PHP scripting areas can be found here:

3'rd way:

- you can try using the $invalid method as explained in the article above
