Form submission with double opt-in (DOI) e-mail verification

[wnzirngibl]

Hello community,
we're trying to implement a kind of subscription workflow for anonymous users with Statamic forms.

One necessary feature is the validation of the user's e-mail address by a double opt-in verification mail - so the form must not be submitted before the e-mail address is validated.

So the desired workflow would be:

1. user fills out Statamic form
2. user gets verification mail to the e-mail address they entered
3. user clicks on verification link in e-mail
4. the form is submitted

Being rather new to Statamic I was hoping to find something like that in core or an add-on, but I couldn't find very much.

I found something in the Laravel docs about their user verification process: https://laravel.com/docs/10.x/verification

At the moment, that would be the best guess, trying to implement something along these lines - although we don't really need the form data as users, it's really only about verifying the e-mail address before sending out the form.

If anybody has ideas about how to achieve this with Statamic, help would be greatly appreciated.

You could hook into the events Statamic provides for submissions (eg SubmissionCreated), and mark the Submission as not validated. Then use the email functionality already there to give a link to a custom route for verification that then marks it as validated.

Thanks a lot for your ideas! Sounds like a promising way to go.

However, I don't have any idea how to provide this custom route for verification - is that something generated by Statamic, or would I have to implement it by myself? Is there any documentation about the email functionality you are mentioning?

You would have to implement the route yourself

OK, thanks. I'll look into it.

I have implemented a solution to handle the verification during the form submission, I've thought to create a Statamic Addon.
