Is there a way to pass parameters back to the controller?
My situation:
I have a {{form form_name}} tag which creates a form, collects and saves the data on :post. I would like to give a cookie acknowledging that this particular form was processed so that I can present additional information to whoever submitted the form.
How can I pass a message from the form_tag back to the controller?
This is a weird situation where I need to assign a cookie but I only know about whether I should do so in a model instantantiated inside a liquid tag.
Thank you!
