# Biblatex \autocite in case of would-be nested footnotes

I have the same situation as the following user: biblatex: Enhancing \autocite in case of would-be nested footnotes

I want to use \autocite within a \footnote. This results in the citation being wrapped in parenthesis. I want to change the behavior of \autocite used within \footnote to print the citation without the parenthesis like a simple call of \cite would do.

How can I change the behavior of \autocite within the \footnote?

Which citation style (authoryear, authortitle, ...) do you use? –  lockstep Aug 22 '12 at 8:10
I use biblatex-juradiss. –  Michael Aug 22 '12 at 8:34

The solution depends on the citation style. For styles like authortitle, verbose and their respective variants (and also for biblatex-juradiss) that execute autocite=footnote, we only need to redefine the underlying \smartcite macro so that it does not add parentheses in footnotes (by replacing \mkbibparens with \textnormal).

\documentclass{article}

\usepackage[style=authortitle]{biblatex}

\DeclareCiteCommand{\smartcite}[\iffootnote\textnormal\mkbibfootnote]
{\usebibmacro{prenote}}
{\usebibmacro{citeindex}%
\usebibmacro{cite}}
{\multicitedelim}
{\usebibmacro{postnote}}

\DeclareMultiCiteCommand{\smartcites}
[\iffootnote\textnormal\mkbibfootnote]{\smartcite}{\multicitedelim}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
author = {Author, A.},
year = {2001},
title = {Alpha},
}
\end{filecontents}

\begin{document}

\null\vfill% just for the example

Some text \autocite{A01}.

Some text.\footnote{A footnote \autocite{A01}.}

\printbibliography

\end{document}


For styles like authoryear that by default execute autocite=inline (which uses \parencite), we need to declare a new autocite option value (say, inlineplainfootnote) that points to a new underlying macro (say, \mysmartcite) that does what you want (add parentheses in normal text, don't add them in footnotes).

\documentclass{article}

\usepackage[style=authoryear]{biblatex}

\DeclareAutoCiteCommand{inlineplainfootnote}{\mysmartcite}{\mysmartcites}

\DeclareCiteCommand{\mysmartcite}[\iffootnote\textnormal\mkbibparens]
{\usebibmacro{prenote}}
{\usebibmacro{citeindex}%
\usebibmacro{cite}}
{\multicitedelim}
{\usebibmacro{postnote}}

\DeclareMultiCiteCommand{\mysmartcites}
[\iffootnote\textnormal\mkbibparens]{\mysmartcite}{\multicitedelim}

\ExecuteBibliographyOptions{autocite=inlineplainfootnote}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
author = {Author, A.},
year = {2001},
title = {Alpha},
}
\end{filecontents}

\begin{document}

\null\vfill% just for the example

Some text \autocite{A01}.

Some text.\footnote{A footnote \autocite{A01}.}

\printbibliography

\end{document}

Thank you. That was wonderfully helpful. –  Michael Aug 22 '12 at 9:39
