We use for a handful of clients – they offer a great mailing list system for groups of all sizes. A client recently launched a number of subgroups and wanted a streamlined form with checkboxes for each list instead of sending users to a number of separate signup links. Something like this: signup

Once submitted, the email address will be added to all selected subgroups without further confirmation. The member first/last name will be added to, as well as any entered Moderator Notes (helpful for secondary membership details).

You’ll need a paid Premium membership in order to use the “direct add” feature and have the code below work for you (Premium details)

Setup instructions:

  • Create a Gravity Form similar to the example above. Note the form and field IDs
  • Within the Gravity Form, create a checkbox field with your subgroups. You can use anything for the Label, however the Value needs to match the correct subgroup syntax like “parent-group+subgroup”
  • Copy the code below into your theme functions.php or a custom functionality plugin
  • Customize the code below with the correct form and field IDs, your admin login details, and group name

The code below has multiple commented Gravity Forms logging lines – you’ll need to enable GF logging in order to use them if you have any problems (How to enable logging)
