Answered Conditional FormIt Hook

Hi all,

I'm new to MODX - and I think you're gonna see me around here quite often.

We're currently working on a form which is doing several things at the same time. Among other things the user can subscribe to a newsletter. We are using FormIt (2.0.3) and all is well. Except, we are trying to have a conditional hook, as such:

&hooks=`recaptcha,spam,email[[+rdoSubscribe:neq=`No`:then=`,mChimpXSubscribe`:else=``]],redirect`

We can't get the output filter to work (tried with If Package as well - no luck).

In the email itself, [[+rdoSubscribe]] is output as Yes or No as expected. The radio buttons in the template look as such:

<input type="radio" name="rdoSubscribe" id="rdoSubscribeYes" value="Yes" [[!+fi.rdoSubscribe:FormItIsChecked=`Yes`]] />Yes
<input type="radio" name="rdoSubscribe" id="rdoSubscribeNo" value="No" checked="checked" [[!+fi.rdoSubscribe:FormItIsChecked=`No`]] />No

Any idea how to have a conditional hook based on a radiobutton. That would be really helpful.

Thank in advance.

put the logic into your hook!

Rather than rewriting the email hook, you could add another custom hook before the email hook (it could probably be the first hook in the list). Have it return false if the value is no and the email won't be sent. If a hook returns false, the hooks after it won't execute.

Thanks for the answers.

Bruno17: Yes, that is an option and we get that to work. But essentially we are changing a thrid-party core code, which I am not a fan of.

BobRay: That's not actually what we need. The email needs to be sent either way. But if the user selects yes to subscribe to the newsletter, we want to execute the mailchimp hook. As Bruno suggests, we can always do the check in the mailchimp snippet and simply return true (i.e. abort) if subscription wasn't selected (for the FormIt package to continue to the redirect). But I dislike core hacks. I'd rather have a condition in the FormIt extra.

So, the question remains, is it possible and if so how to add a condition in the FormIt extra.

Thank you.

You could put your custom hook in instead of the mailchimp one, then execute the mailchimp snippet conditionally with $modx->runSnippet().

The redirect hook should still execute when you return from your snippet (as long as the mailchimp snippet has a return at the end).
