Detecting Chapter

If you want to know if your documentclass supports chapter then use the following code:
\begingroup\expandafter\expandafter\expandafter\endgroup\expandafter%
\ifx\csname chapter\endcsname\relax
	%%% \chapter is undefined or \relax
\else
	%%% \chapter is defined and not \relax
\fi

Unnumbered Chapters/Sections into TOC
  • Some chapters into TOC is possible with
    \addcontentsline{toc}{chapter}{My unnumbered Chapter}
    just after the beginning of the chapter.


    Chaptertitle
    If you want to use the chapternumber and/or title for a header/footer write into the preamble:
    \newcommand{\ChapName}[1]{}
    \newcommand*{\oldChapter}{}
    \let\oldChapter\chapter
    \renewcommand*{\chapter}{%
      \@ifstar{%
        \starchapter
      }{%
        \@dblarg\nostarchapter
      }%
    }
    \newcommand*{\starchapter}[1]{%
      \renewcommand{\ChapName}{#1}%
      \oldChapter*{#1}%
    }
    \newcommand{\nostarchapter}{}
    \def\nostarchapter[#1]#2{%
    % #1: toc entry
    % #2: main entry
      \renewcommand{\ChapName}{#2}%
      \oldChapter[{#1}]{#2}%
    }
    now you have the commands \thechapter for the number and \ChapName for the title, which you can place anywhere in the header/footer.
    You can get the same for section/subsection a.s.o.


    Chaptername
    If you use babel than you can't change the name "Chapter" with a \renewcommand ... because babel overwrites this change. Write as very first command in your doc in TeX
    \def\chaptername{MyChapter}
    or write into the preamble f.ex. for the german language
    \addto\captionsgerman{%
       \renewcommand{\chaptername}%
         {insert your chaptername}%
    }
    Look here if you do not want any leading name for the chapter.
    Start Chapter on Left Side
    In some cases it may be useful to start a new chapter on the left side instead the default right side. Put the following in the preamble:
    % Definition from latex.ltx modified
    \makeatletter
    \renewcommand*{\cleardoublepage}{%
      \clearpage
      \if@twoside
        \ifodd\c@page
          \hbox{}%
          \newpage
          \if@twocolumn
            \hbox{}%
            \newpage
          \fi
        \fi
      \fi
    }
    \makeatother
