protected function InlineEntityFormBase::makeIefId in Inline Entity Form 8

Makes an IEF ID from array parents.

IEF ID is used a) for element ID, b) for form state keys. We need the IEF form ID to reflect the tree structure of IEFs, so that the form state keys can be sorted to ensure inside-out saving of entities.

Also, "add" and "edit" IEFs have different array parents, which messes up form state, so we fixup this here with a, errrm, pragmatic hack.

Parameters

string[] $parents: The array parents.

Return value

string The resulting inline entity form ID.
