[Tex/LaTex] Chapter name and title on page header

header-footer

I would like to insert the chapter number and name on the left header of a page.
So far, I have used the following code, which works very well:

\renewcommand{\chaptermark}[1]{\markright{\thechapter\;\; #1}{}}

\lhead[\fancyplain{}{}]{\fancyplain{}{\bfseries\rightmark}}

\chead[\fancyplain{}{}]{\fancyplain{}{}}

\rhead[\fancyplain{}{}]{\fancyplain{}{\bfseries\thepage}}

However, if I happen to include sections, this code does not work anymore, replacing the chapter number and name by the section number and name (capitalised, for some reason).

Could anybody please help? Thanks.

\documentclass{book}
\usepackage[a6paper]{geometry}% just for the example
\usepackage{fancyhdr}
\usepackage{lipsum}

\pagestyle{fancy}
\renewcommand\chaptermark[1]{\markboth{\thechapter\ #1}{}}
\fancyhf{}
\fancyhead[L]{\bfseries\leftmark}
\fancyhead[R]{\bfseries\thepage}
\renewcommand\headrulewidth{0pt}% suppress the header rule

\begin{document}

\chapter{A test chaper}
\section{A test section}
\lipsum[1-5]

\end{document}

The result:

[Tex/LaTex] Displaying the range of sections on the page in the header

Since class memoir is used, starting a chapter on any page is easy:

\renewcommand*{\clearforchapter}{\clearpage}

Getting the headers right is much more complicate. Having page style plain for the first page of chapters would simplify this task a lot, because then the section values in the mark registers can be reset easily. The example below uses lots of additional mark registers instead (using eTeX and package etex) to remember section titles, section names and chapter numbers.

Remarks:

The section title is remembered in \MarkSectionTitle. Its chapter number is put in \MarkSectionChapterNumber. The title is only printed, if this chapter number matches the current chapter number to avoid printing the title from the previous chapter at the starting pages of a new chapter.
Unnumbered chapters/sections are unsupported/poorly supported.
The numbering stuff has prototype quality only. There might be some missing cases/bugs.
\MarkSectionEarlyNumber was added to catch the case where a section starts a new page. That means, the previous section also ends on that page, but the first number of the header should be the new section on the page.

The example file:

\documentclass{memoir}

[Tex/LaTex] Header not displaying correctly on chapter page due to subsection

We must give more structure to the right mark emitted by the \chapter command; so we do

\renewcommand{\chaptermark}[1]{%
  \markboth{\chaptername\ \thechapter}
           {\noexpand\firstsubsectiontitle}}

The \subsectiontitle macro will be defined by the \subsection command; of course it won't work if no subsection starts in the first page:

\renewcommand{\subsectionmark}[1]{%
  \markright{#1}\gdef\firstsubsectiontitle{#1}}

Here's an example; notice some changes I've made to your code. For instance I've redefined the \sectionmark command so it doesn't emit any mark.

The solution to the numbering problem of subsection is to \setcounter{secnumdepth}{1}.

\documentclass{report}

% PACKAGES
\usepackage{fancyhdr}
\usepackage{lastpage} % Allows referencing of the last page to allow footer to read: "Page [Current page] of [Total number of pages]."
\usepackage{comment} % Allows comments of the type: \begin{comment}This text is commented out.\end{comment}
%\usepackage[colorlinks=true]{hyperref} % Turns table of contents and labels into clickable links. Commented out to speed up compiling.
\usepackage[T1]{fontenc} % Allows use of ">" symbol.
\usepackage{lmodern} %Not really sure what this is for.

% FORMATTING
% Header and Footer
\pagestyle{fancy}

% Allows calling chapter and section names in headers and footers.
\renewcommand{\chaptermark}[1]{%
  \markboth{\chaptername\ \thechapter}
  {\noexpand\firstsubsectiontitle}}
\renewcommand{\sectionmark}[1]{}
\renewcommand{\subsectionmark}[1]{%
  \markright{#1}\gdef\firstsubsectiontitle{#1}}
\newcommand\firstsubsectiontitle{}

% General Header and Footer
\fancyhf{}
\fancyhead[L]{\DocumentAuthor} 
\fancyhead[R]{\BookAuthor>\leftmark>\rightmark}
\fancyfoot[C]{Page \thepage\ of \pageref{LastPage}}

% Chapter Header and Footer
\fancypagestyle{plain}{%
  \fancyhf{} \fancyhead[L]{\DocumentAuthor}%
  \fancyhead[R]{\BookAuthor>\leftmark>\rightmark}%
  \fancyfoot[C]{Page \thepage\ of \pageref{LastPage}}%
}

% Header/Footer Separation-line Width
\renewcommand\headrulewidth{0.4pt} 
\renewcommand\footrulewidth{0.4pt}

\setlength\parindent{0pt} % Remove paragraph indentation.

% NAME AND CLASS SECTION
\newcommand{\DocumentAuthor}{Author Name}
\newcommand{\BookAuthor}{Book Author}

\setcounter{secnumdepth}{1}

%DOCUMENT
\begin{document}

\tableofcontents
\thispagestyle{empty}

\chapter{Title of Chapter 1}
\section{Sample Problems}
\subsection{Title of Subsection 1}
\pagebreak{}
\subsection{Title of Subsection 2}
\subsection{Title of Subsection 3}
\pagebreak{}
\subsection{Title of Subsection 4}

\end{document}

With this code the first subsection in the page will be put in the header.

What's \noexpand\firstsubsectiontitle doing? The \markboth and \markright commands must record the current values of the counters and titles, so their arguments are passed through an \edef; this, in the case of the first chapter and English language, would set a left mark with value Chapter\ 1. If we said only \firstsubsectiontitle in the second argument, it would be expanded leaving a wrong right mark because it would be empty for the first chapter and would contain the last subsection in the preceding chapter!

So we say "dear TeX, don't expand \firstsubsectiontitle right now, but only when you'll set the header."

Actually, if there can be more than one subsection in the chapter pages, a different solution should be used:

% Allows calling chapter and section names in headers and footers.
\renewcommand{\chaptermark}[1]{%
  \markboth{\chaptername\ \thechapter}
           {\noexpand\firstsubsectiontitle}%
  \global\firstsubsectionmarktrue}
\renewcommand{\sectionmark}[1]{}
\renewcommand{\subsectionmark}[1]{%
  \markright{#1}%
  \iffirstsubsectionmark
    \gdef\firstsubsectiontitle{#1}%
  \fi
  \global\firstsubsectionmarkfalse}
\newif\iffirstsubsectionmark
\def\firstsubsectiontitle{}

so that the first subsection would set the mark.
