[Tex/LaTex] Page numbering style with fancyhdr

fancyhdrheader-footerpage-numbering

I am having some issues with setting my thesis formatting and I may need some assistance with the fancyhdr package.
The problem is, I made by own style from a combination of two templates and there must be some inherited settings from each of them (and each different), but I am unable to locate them. This is what the pages look like:
An example of my problem

As you see, the LEFT pages have the page number as a footer under a line and the RIGHT pages have the page number as a header and with no line. I want to have the chapter name in the headers and page numbers in the footers.
This is a part of my preamble:

\documentclass[a4paper,12pt,twoside,openright, english]{book}

\clearpage

What have I missed? I thought I have all the settings.

Best Answer

There is at least a \pagestyle{fancy} missing. The normal pages still use pagestyle headings. Note that \pagestyle{fancy} must be used at least once before the redefinition of \chaptermark and \sectionmark, because the first call of \pagestyle{fancy} also redefines this commands.

I am not sure about the desired page layout. Maybe

Code (without all the unrelated stuff):

\documentclass[a4paper,12pt,twoside,openright,english]{book}
\usepackage{babel}
\usepackage{blindtext}% only for dummy text

\addtolength{\headheight}{3pt}
\usepackage{fancyhdr}
\pagestyle{fancy}% <- must be used before the redefinition of \chaptermark and \sectionmark
% change the marks set by \chapter and \section
\renewcommand{\chaptermark}[1]{\markboth{#1}{}}
\renewcommand{\sectionmark}[1]{\markright{\thesection\ #1}}
% change fancy style
\fancyhf{}
\fancyhead[LE]{\nouppercase{\rightmark}}
\fancyhead[RO]{\nouppercase{\leftmark}}
\fancyfoot[LE,RO]{\thepage}
\renewcommand{\headrulewidth}{0.5pt}
\renewcommand{\footrulewidth}{0.5pt}
% change plain style (eg. used on chapter pages)
\fancypagestyle{plain}{%
  \fancyhf{}
  \fancyfoot[LE,RO]{\thepage}
  \renewcommand{\headrulewidth}{0pt} % comment this line, if there should be a headsepline on plain pages too
}

\usepackage{blindtext}
\usepackage[nottoc]{tocbibind}% LoF and LoT should get a ToC entry
\begin{document}
\tableofcontents
\listoffigures
\listoftables
\blinddocument
\end{document}

If there should be a headsepline on plain pages too, remove the change of \headrulewidth inside the definition of page style fancyplain.

Additional remark: In your code the \addcontentsline{toc}{chapter}{\listfigurename} and \addcontentsline{toc}{chapter}{\listtablename} are at the wrong place. They would add the page numbers of the last pages of LoF and LoT to the table of contents. You could use package tocbibind instead.
