Obligatory Subject and SubjectClass

Postby svillanueva » Fri Mar 28, 2008 1:50 am


in our journal, when an author submits an article, we would like him/her to enter, at least, one keyword. We use 2 kind of keywords, the variables subject and subjectClass. We would like to include these 2 fields in the list of obligatory fields in the author's form. But knowing that, if the author gives a subject keyword, then the subjectClass can be empty and vice versa.

How can I do that? What kind of form class do we have to use? I've seen we need to add some check at


but I don't know exactly how to do it.
