[Tex/LaTex] How to get the author and chapter names in header; alternatively using fancyhdr

book-designfancyhdrheader-footer

I want to set a header/footer which shows:

  1. Chapter name on odd numbered page;
  2. Author name (different authors in different chapters) in even numbered pages;
  3. Page number in central footer.

Any help would be appreciated.
Thanks.

Best Answer

The following introduces \chapterauthor to set and store the authors associated with your \chapters. This allows you to use the stored details within the \fancyhead[LE] part.

enter image description here

\documentclass{book}

\usepackage{blindtext}
\usepackage{fancyhdr}

\makeatletter
\newcommand{\chapterauthor}[1]{%
  \def\@chapterauthor{#1}% Store chapter authors
  {\bfseries #1}% Set chapter authors
  \par
}

\fancyhf{}% Clear header/footer
\fancyhead[RO]{\leftmark}% Chapter details in book
\fancyhead[LE]{\@chapterauthor}% Stored \chapterauthor details
\fancyfoot[C]{\thepage}
%\renewcommand{\headrulewidth}{0pt}% Remove header rule
%\renewcommand{\footrulewidth}{0pt}% Remove footer rule (default)
\pagestyle{fancy}
\makeatother

\begin{document}

\chapter{Wombat}
\chapterauthor{Author Aa, And Author Bb}
\blindtext[5]
\section{tabmow}
\blindtext[5]

\chapter{Capybara}
\chapterauthor{Author Cc, And Author Dd}
\blindtext[5]
\section{arabypac}
\blindtext[5]

\chapter*{Mara}
\chapterauthor{}% No chapter author
\blindtext[5]
\section{aram}
\blindtext[5]

\end{document}
