# How can I have a footnote with an \url in a section title?

When I have a footnote with an `\url` in the section-header, the table of contents shows nothing with it. Why and how can I fix the issue?

Please add a short example that reproduces the problem. – Ian Thompson Mar 9 '12 at 11:48

It's in general a bad idea to footnote section titles. The footnote can go, if really necessary, to the first paragraph.

In case you can't get without it, you have to use the optional argument:

``````\section[Section title]{Section title\footnote{A footnote}}
``````

otherwise you'll footnote also the table of contents and the headers, which is wrong (and with a `\url` command you'll get many errors).

If the URL contains special characters, LaTeX would have a very hard job, so you should consider the `\urldef` command.

Use like this:

``````\section{Section title\protect\footnote{A footnote}}
``````

...does not work, even more errors -1 unless clarified. – hhh Mar 9 '12 at 12:24
It does work for me, but egreg's solution seems to be better. See this similar question: tex.stackexchange.com/questions/153329/… – Yorick Sijsling Nov 11 '15 at 13:35
@hhh It works for me (+1) in a quite large document with lots of packages, bibliography, complicated tikz drawings, and extra commands. May be you should revise the spelling; in the beginning I had a spelling error in `\protect`, and because of that I got more errors. – loved.by.Jesus Nov 15 '15 at 11:59
