# No Chapter #num in the header with fancyhdr

I'm using fancyhdr and I want to have the header with chapters name without number opposite to section name. I've tried a lot of configurations, but none works with in this case.

How could be fixed?

ps: This short document has a different style in the Chapter page, but in the real document this is fixed.

\documentclass[11pt,a4paper,twoside,titlepage,openany]{book}
\usepackage{lipsum}
\usepackage[T1]{fontenc}
\usepackage{amsfonts}
\usepackage[utf8]{inputenc}
\usepackage{amssymb}
\usepackage[italian]{babel}

\usepackage{lmodern}
\usepackage{sectsty}

\usepackage{geometry}
\geometry{
left=35mm,
right=30mm,
top=27mm,
bottom=30mm
}

\usepackage{fancyhdr}

\pagestyle{fancy}
\fancyhf{}
\renewcommand\footrulewidth{0.4pt}

\renewcommand{\chaptermark}[1]{\markboth{#1}{}}
\renewcommand{\sectionmark}[1]{\markright{#1}}

\fancyfoot[LE,RO]{\thepage} % Left side on Even pages; Right side on Odd pages

\begin{document}
\chapter{Chapter Intro}
\lipsum
\chapter{Chapter with subsections}
\section{section foo}
\lipsum
\subsection{subsection bar}
\lipsum
\end{document}

• Does the folowing link helps? tex.stackexchange.com/questions/89569/… I mean the '\rhead' and '\lhead' commands... You don't need others I think – koleygr Aug 25 '17 at 15:51
• Nope, because I need a book style so I have odd and even pages with opposite headers. I can do this, anyway, the problem is that I can't take away the "Chapter 1." from "Chapter 1. INTRO", for example. – Il Dordollano Aug 25 '17 at 15:58
• I removed just babel and nowhere is shown a chapter (no number no name) – koleygr Aug 25 '17 at 16:02
• Exactly, this is the problem. With this configuration, there is no chapter and no name. Remove \fancyhf{} to see something, but this make double numbering page in the foot. – Il Dordollano Aug 25 '17 at 16:17

With

\renewcommand{\chaptermark}[1]{\markboth{#1}{}}


each chapter sets the left mark to the chapter name. So you have to use

\fancyhead[LO,RE]{\leftmark}


to get the desired result.

Code:

\documentclass[11pt,a4paper,twoside,titlepage,openany]{book}
\usepackage{lipsum}% only for dummy text

\usepackage{geometry}
\geometry{
left=35mm,
right=30mm,
top=27mm,
bottom=30mm,
}

\usepackage{fancyhdr}

\pagestyle{fancy}
\fancyhf{}
\renewcommand\footrulewidth{0.4pt}

\renewcommand{\chaptermark}[1]{\markboth{#1}{}}
\renewcommand{\sectionmark}[1]{\markright{#1}}

\fancyfoot[LE,RO]{\thepage}

\begin{document}
\chapter{Chapter Intro}
\lipsum
\chapter{Chapter with subsections}
\section{section foo}
\lipsum
\subsection{subsection bar}
\lipsum
\end{document}


If there are some starred chapters which should get a header entry too, use \markboth manually. Example:

\chapter*{Introduction}\markboth{Introduction}{}


Of course you can define a macro to do that.

• I tested your code with a chapter* (see his comments on my solution) and doesn't give the chapter there... I think your way with my definitions of chapter will give the same result as mine and is simpler (Or any way you can include this option (of starred) in your code) – koleygr Aug 25 '17 at 18:29
• @koleygr Perfect! Thanks for the help. I've tried that two options, simplicity is better of course :D – Il Dordollano Aug 28 '17 at 10:36

With this answer you can select the depth of sectioning that appear in fancyhead using \MaxLevel variable. (For example if you use number 2, only sections will be shown on fancy header)

Also, you have the extra option to use a deferent fancy head content from the name of the chapter or section etc by using starred sectioning with optional argument (something that doesn't allowed in ordinary latex)

An extra feature that may not be desired is that labels are added automaticaly to every chapter, section or subsection as {c:1} for chapter 1 (real first) {s:2} for second section {sss:3} for third subsubsection etc.

• You can do the same as I did with chapter to the section... but I did not really understood what you want with the sections... (Numbered or not) – koleygr Aug 25 '17 at 16:35
• You are close to my idea, thanks! But I want to remove the numbers also from chapter, leaving only the name, because I've got some \chapter* that breaks this things. – Il Dordollano Aug 25 '17 at 16:42
• @IlDordollano Edited my answer but removed sections numbering too (If you want I can add it back) – koleygr Aug 25 '17 at 17:22
• Doesn't work... changing it! – koleygr Aug 25 '17 at 17:27
• Sorry, but the issue is in the Last Edit Answer too: insert \lipsum[2-5] in Chapter 1 ... before the \subsection command. – esdd Aug 25 '17 at 20:11
