I am new to Plone and am working a form in Plone 4.1. I would like to override the form mailer subject line so it is a string from the input from a subject field from the form and then the form name. I am not sure how to write this though.
Go to the form, click on "Contents", click on the Mail-adapter, click on "Edit, click on "Overrides" and insert this line in the field "Subject Expression":
python: folder.Title() + ': ' + request.form['subjekt']
Where subjekt stands for the field-name you want to get the value of.
Here's a helpful doc about the available context-variables:
