[Tex/LaTex] fancyhdr – Only show sections, not subsections

fancyhdrheader-footer

Is there a way for the header to only print the title of the parent section? So in the example below, the subsection{LOL} page will have "1.1 LOL" written in the header. I just want it to say "Introduction" which is the parent section.

\documentclass[a4paper,12pt]{scrartcl}

\usepackage{fancyhdr}

\begin{document}
\pagestyle{fancy}
\renewcommand{\sectionmark}[1]{\markright{#1}}

\fancyhf{}

\rhead{\fancyplain{}{MyName}} % predefined ()
\lhead{\fancyplain{}{\rightmark }} % 1. sectionname
\cfoot{\fancyplain{}{\thepage}}

\section{Introduction}
\newpage
\subsection{LOL}

\end{document}

Either you also redefine \subsectionmark or use the \leftmark; in article type classes, \subsection emits a \markright command.

\documentclass[a4paper,12pt]{scrartcl}

\usepackage{fancyhdr}

\pagestyle{fancy}
\renewcommand{\sectionmark}[1]{\markboth{#1}{}} % set the \leftmark

\fancyhf{}
\fancyhead[R]{MyName} % predefined ()
\fancyhead[L]{\leftmark} % 1. sectionname
\fancyfoot[C]{\thepage}
\fancypagestyle{plain}{%
  \fancyhf{}%
  \renewcommand{\headrulewidth}{0pt}%
}

\begin{document}
\section{Introduction}
\newpage
\subsection{LOL}

\end{document}

Note also the "modern" fancyhdr syntax that avoids \fancyplain.

[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.

You can add \markboth to the numberless version of \chapter. I reorganized the call to packages and the settings. Remove kantlipsum at the end that's only used for generating mock text in the example.

Note that emptypage avoids the redefinition of \cleardoublepage by hand.

This doesn't spare you from issuing \addcontentsline if you need the table of contents.

\documentclass[english]{book}

\usepackage[paperwidth=32pc,paperheight=48pc]{geometry}
\geometry{verbose,tmargin=9pc,bmargin=6pc,lmargin=5pc,rmargin=5pc}

\usepackage{fontspec}
\usepackage{fancyhdr}
\usepackage{array}
\usepackage{enumitem}
\usepackage{yfonts}
\usepackage{xcolor}
\usepackage{colortbl}
\usepackage{titlesec}
\usepackage{chngcntr}
\usepackage{emptypage} % avoids redefining \cleardoublepage

\counterwithin*{footnote}{section}

\renewcommand{\thechapter}{\Roman{chapter}}

\titleformat{\chapter}[display]
  {\normalfont\scshape\normalsize\filcenter}
  {\normalsize\thechapter\ }
  {0pt}
  {\vspace{1pt}\normalsize}
\titleformat{name=\chapter,numberless}[display]
  {\normalfont\scshape\normalsize\filcenter}
  {}
  {0pt}
  {\vspace{1pt}\normalsize\addchaptertitle}
\titlespacing{\chapter}{0pt}{20pt}{80pt}

\newcommand{\addchaptertitle}[1]{%
  #1\markboth{#1}{#1}%
}

\titleformat{\section}
  {\itshape\normalsize\filright}
  {\thesection.}
  {.5em}
  {}
\titlespacing*{\section}{0pt}{60pt}{60pt}

\pagestyle{fancy}
\fancyhead[RE,RO]{\normalfont\scriptsize\thepage}
\fancyhead[LE]{\sffamily\small My Book}
\fancyhead[LO]{\sffamily\small\leftmark}
\fancyfoot{}

\arrayrulecolor{lightgray}

\setcounter{secnumdepth}{3}
\setcounter{tocdepth}{3}

\setmainfont{Minion Pro}
\setsansfont{ITC Goudy Sans Std Book}

\usepackage{kantlipsum} % mock text

\begin{document}
\mainmatter

\chapter*{Introduction}

\kant[1-4]

\chapter{First}

\kant[5-8]

\end{document}

I'll show only page 3 which has the required header.
