[Tex/LaTex] footnotes and floats

floatsfootnotes

I'm having some troubles with using footnotes inside floats.
I use \footnotemark and \footnotetext, but then the float is pushed to the next page, and the footnote remains in the previous one.

As a remedy, I've moved the \footnotetext couple of paragraphs later so now the footnote is located at the right place. BUT, now the numbering is incorrect — in those "in between" paragraphs there was another \footnote which have advanced the counter.

Since the float was pushed – the numbering is reverted now: the footnote in the float (that got the number n) appears after the next footnote (that was assigned to the number n+1, obviously).

Is there any way to fix that, other than manually changing the counters?

Usually it's best not to put footnotes inside floats; the minipage environment sets things up so you can have "local" footnotes for such occasions. E.g.,

\begin{figure}
  \begin{minipage}{\linewidth}
  ...\footnote{blah}...
  \end{minipage}
\end{figure}

The same advice holds for the quite common practice of putting notes for tables directly beneath them rather in footnotes on the page itself.

[Tex/LaTex] Making \footnote work in leftbar environment

A slightly longer code, which allows you to only type \footnote. The idea is to make each footnote append \footnotetext{#1} to a token list. This token list is then typeset at the right place. Some trickery is required to get nesting right, as well as hyperref support. Normally, this can be used for other (non-verbatim-ish) environments.

Comments in the code.

\documentclass{article}
\usepackage{etoolbox} % for "\pretocmd".
\makeatletter
%
% User command, see the end of the preamble for use.
% We redefine the environment by adding "\savefoot@begin" at 
% the beginning, and "\savefoot@end" at the end.

\newcommand{\DeclareSavefootEnvironment}[1]{%
  \expandafter\pretocmd\csname #1\endcsname
              {\savefoot@begin}{}{\savefoot@patch@error{#1}}%

\newcount\c@savefoot@depth
\newtoks\savefoot@toks
%
% "\savefoot@begin" starts an environment which saves footnotes.
% We only want to output footnotes outside any such environment,
% so we count how deep we are in this kind of environment using
% the count "\c@savefoot@depth", which pretends to be a LaTeX
% counter. 
%
% We will store all the "\footnotetext" into the toks 
% "\savefoot@toks". This is initialized _locally_ at the start
% of each "savefoot" environment.
% 
\newcommand{\savefoot@begin}{%
  \advance\c@savefoot@depth by 1\relax  
  \savefoot@toks={}}
%
% When ending a savefoot environment, we check if it was the 
% outermost one. In that case, "\@secondoftwo", we output the
% "\footnotetext" that we saved, after the end of the group.
% The "\endgroup" must be explicitly there; this is the case
% because of how "\end{...}" works in LaTeX2e.
% 
% Since the register "\savefoot@toks" is restored at the end 
% of the group, we need to expand it inside the group, then 
% send "\savefoot@append{<expanded \savefoot@toks>}" after the
% "\endgroup", hence the "\expandafter"s. Same thing when we 
% need to typeset.
% 
\newcommand{\savefoot@end}{%
  \ifnum\c@savefoot@depth>\@ne

\newcommand{\savefoot@append}[1]{%

%
% Now the footnote command. We save the old definition,

% 
%    \savefoot@setcounter{<explicit number>}\footnotetext{<text>}
% 
% to our register. This will be typeset at the end. We cannot
% just do "\footnotetext[<explicit number>]{<text>}", because
% the hyperref package does not like that.

\let\savefoot@old@footnote\footnote

% ============= Example =====================

\usepackage{framed}
\usepackage{hyperref}
\DeclareSavefootEnvironment{leftbar}

\begin{document}

Some text,\footnote{With a normal footnote.} in which 
footnotes are preserved.\footnote{Even when you put several 
  in a row.}\footnote{Like this.}

\begin{leftbar}
  Also true for the leftbar environment.\footnote{The relevant 
    commands are placed after the end of the environment.} 
  \begin{leftbar}
    And we check that nesting works.\footnote{That was the tricky part\ldots}
  \end{leftbar}
  Maybe it breaks after nesting?\footnote{Let's see.}
\end{leftbar} 

More footnotes.\footnote{Like this.}\footnote{And that.}

\begin{leftbar}
  And another leftbar environment to be sure.\footnote{Does it 
    work? I'll see soon, when I compile.}
\end{leftbar}

\end{document}

[Tex/LaTex] Order of footnotes with packages afterpage and footnote

There is no way to do this with floating figures without rewriting half of latex: the caption (including any footnote marks) is set at the point of the figure environment and a floating figure can float past footnotes, thus getting the footnote numbers out of order.

If you really want this output style (I can see no good reason for it, a float is by design a distinct object not in the main flow of text on the page, and so having its footnotes in the page just seems wrong) then you need to use non floating figures.

You can use float package \begin{figure}[H] or or caption or capt-of package \captionof{figure}{...} then the figure is not a floating object but fixed in the page, and you can then use \footnotemark in the caption and \footnotetext immediately after the \end{figure} and they will come on the same page.
