I do not see an option in the Mailchimp form action to only subscribe to the Mailchimp newsletter if a checkbox is ticked. I do not want every contact form to subscribe to the newsletter, only the people who select the checkbox I have created in the Bricks form. What is the point of the Mailchimp action if you cannot conditionally subscribe if a checkbox is ticked? This option does not show up for me.
Hi @truetundra ,
I just moved this thread to feature request category.
It is not possible to have conditional action in the Bricks form.
This is already in our idea board.
Thank you.
Regards,
Jenn
Has this progressed at all? Is it now possible?
Hi James,
I’m working on a php code snippet for this at the moment. When I get it working I’ll post it here 
Here is the code snippet.
You will have to replace the following values:
REPLACE_WITH_YOUR_API_KEY
REPLACE_WITH_YOUR_AUDIENCE_ID
REPLACE_WITH_YOUR_DATA_CENTER
REPLACE_WITH_YOUR_FIRST_NAME_MERGE_TAG
REPLACE_WITH_YOUR_BRICKS_FORM_ID
REPLACE_WITH_YOUR_NAME_FIELD_NAME
REPLACE_WITH_YOUR_EMAIL_FIELD_ID
REPLACE_WITH_YOUR_NEWSLETTER_FIELD_NAME
REPLACE_WITH_THE_EXACT_NEWSLETTER_OPT_IN_VALUE
