title: Iterating over submitted form fields in Flask?
body: <p>In Flask 0.8, I know I can access individual form fields using <code>form.fieldname.data</code>, but is there a simple way of iterating over all the form fields? I'm building an email message body, and I'd like to loop over all the fields and create a fieldname/value entry for each, as opposed to manually building it by naming each field and appending.</p>
