We don't know. What is "affected projects" in your system?
I ask because it's not a standard JIRA Core field name, so the question is how you've set it up, or if you've added an add-on which adds it. In either case, you'll need to explain how you've implemented it before we can help you with the name.
Also, what you mean by "name" needs clarifying - the usual way to describe a field in English is to effectively say "The field name is 'Affected Projects'", so, you already have the name of the field there. I suspect you're looking for the ID instead? If, for example, it is a custom field, most of the JIRA code will refer to customfield_nnnnn (where nnnnn is a unique number)
Ok, great, that means that JIRA will "name" it "Affected Projects" (unless you rename it!), but always refer to it internally as customfield_nnnnn You can get that nnnnn by going to the list of custom fields and hovering over the links to edit/configure/delete and looking for id=12345 in the url it links to. There are other ways, but this is the one I've always used because it's always worked, and the others change sometimes.
