Biblatex: philosophy-verbose

Question

I want to use both philosophy-verbose and bibcitefn option for smallcaps-author. I prove that this match is possible only if I use philosophy-classic style, but the guide (p. 15) tells that it is possible also for philosophy-verbose style.

So, this is my bib code.

\usepackage[style=italian]{csquotes}
\usepackage[style=philosophy-verbose,scauthors=bibcitefn,backend=biber]{biblatex}

Then, this is an example and I remind you that the following upper case in this example should be small caps.

So, document:

This is the body of my page. Follows the name of one author I want to cite: he is Trump, the former potus and he said that if he were still the potus today, Russia wouldn't invade Ukraine (1).

---

1 D. TRUMP, My words, Oxford University Press, Oxford 2022, p. 5.

And the code of this document should be:

This is the body of my page. Follows the name of one author I want to cite: he is \citeauthor{trump2022}, the former potus and he said that if he were still the potus today, Russia wouldn't invade Ukraine \footcite[5]{trump2022}.

Answer 1

In a way the biblatex implementation of full citations often mixes citation and bibliography settings. This means that they sometimes fall through the cracks when options are offered that distinguish citation and bibliography output.

The following redefinition tries to make citations in the footnote also respond to bibcitefn, but even if this works as you hoped in all edge cases, you may still want to contact the biblatex-philosophy developer if the documentation suggests that bibcitefn should do what you expected
