10 years ago I agree a such method is useful, but I'm not sure I get the reason you explained: can you give me an example or get() call which results on the error you described?
Besides, could you add some basic tests? Like calling has("field") with:
- no fields ⇒ false
- a field “field” ⇒ true
- a field “fieldError” ⇒ false
- a field “field[2]” ⇒ true
This method is part of the API so we must prevent regressions… and changing behavior is a regression for existing user code :-)
This will provide a way to test for the presence of a fragment, and prevent the "Undefined variable $single" error that's thrown by the get() method when the fragment doesn't exist.
