Is it possible to have a Bricks form that simply posts to another page? I have a very simple signup form with a name and email field that once submitted needs to go to another page with a couple more options and a captcha. I’m hoping to dynamically populate the name and email fields with the POST vars.
Yes, it is possible. For example, the form element has hooks to intercept the message and process it in PHP. You can also simply create a JS script that will go through the fields and send a post request.
My fault for not being specific enough, but I really meant is it possible within the UI as an action or similar, rather than a custom coded solution. I think I have my answer though 
No. There is no separate action.
