How to print footnote at the end of a chapter

Question

As the title says. Instead of printing it at the bottom of the current page, print it at the end of the current chapter.

Answer 1

You can use packages like enotez, endnotes or maybe pagenotes for stuff like this. Since no MWE was provided the following examples show how to get the result for sections but the usage is analoguous for chapters.

enotez

\documentclass{article}
\usepackage{enotez,lipsum}
\setenotez{
  reset ,
  list-heading = \subsection*{#1}
}
\begin{document}
\section{Foo}
\lipsum[1]\endnote{test a}
\lipsum[1]\endnote{test a}
\lipsum[1]\endnote{test a}
\printendnotes
\section{Bar}
\lipsum[1]\endnote{test b}
\lipsum[1]\endnote{test b}
\lipsum[1]\endnote{test b}
\printendnotes
\end{document}

endnotes

\documentclass{article}
\usepackage{endnotes,lipsum}
\counterwithin{endnote}{section}
\renewcommand\theendnote{\arabic{endnote}}
\begin{document}
\section{Foo}
\lipsum[1]\endnote{test a}
\lipsum[1]\endnote{test a}
\lipsum[1]\endnote{test a}
\theendnotes
\section{Bar}
\lipsum[1]\endnote{test b}
\lipsum[1]\endnote{test b}
\lipsum[1]\endnote{test b}
\theendnotes
\end{document}

pagenote

\documentclass{article}
\usepackage{pagenote,lipsum}
\makepagenote
\renewcommand{\notedivision}{\subsection{\notesname}}
\renewcommand*{\pagenotesubhead}[2]{}
\begin{document}
\section{Foo}
\lipsum[1]\pagenote{test a}
\lipsum[1]\pagenote{test a}
\lipsum[1]\pagenote{test a}
\printnotes*
\section{Bar}
\lipsum[1]\pagenote{test b}
\lipsum[1]\pagenote{test b}
\lipsum[1]\pagenote{test b}
\printnotes*
\end{document}
