Footnotes

Questions answered by this recipe

Is there a way to automatically number footnotes and to have them all automatically displayed at the bottom of the page?

Usage

Download footnote.phpΔ and place it in your cookbook directory.

Add the following line to local/config.php

Wherever you want a footnote in your text, simply use the [^footnote text^] markup.

When you want to display all the footnotes you have so far, below a short blue horizontal rule, use the markup [^#^] (on a line by itself; it won't break the recipe to do otherwise, but it might look funky).

If you do not want the short blue horizontal rule, but just a listing of all the footnotes defined so far, use the markup [^@^] (on a line by itself, too).

You may have multiple occurrences of the listing markups; each one will display only the footnotes created in the text since the last listing markup. (So you can have footnotes at the end of each section of your text, for example.)

Notes

This recipe was extracted from MarkupExtensions for those of us who just want footnote capability without all the other extensions provided by that recipe.

Does not work with the Confluence script : http://pmwiki.org/wiki/Test/Confluence Profiles.SH - 6 Aug 2007

Just an observation that embedding a link inside the Footnote text works normally in the Simple Footnote, but is not processed by the Extended Footnote and simply appears in full as text, complete with its double square brackets. Des October 07, 2007, at 05:30 PM

The code of the footnote script dosen't allow PmWiki to work with CSS pseudo selector: ":target". To highlight some text the text must be betwixt the opening and the closing tags of anchor. I change the lines:

     $r = "<sup><a  class='footnote' href='#fn$fnid'>$fncount</a></sup>".
          "<a name='fnr$fnid' id='fnr$fnid'></a>";
     $foottext = stripslashes( $foottext );
     $fntext .= "<p class='footnote'><a name='fn$fnid' id='fn$fnid'></a>";
     $fntext .= "<sup>$fncount</sup> $foottext <a href='#fnr$fnid'>&uArr;</a></p>";

to:

     $r = "<sup id='fnr$fnid'><a  class='footnote' href='#fn$fnid'>[$fncount]</a></sup>";
     $foottext = stripslashes( $foottext );
     $fntext .= "<p id='fn$fnid' class='footnote'>";
     $fntext .= "<sup>$fncount</sup> <a href='#fnr$fnid'>&uArr;</a> $foottext</p>";

'Tis working only with [^@^] markup. You can add this CSS style for pseudo selector target:

:target {
    -webkit-animation: highlight 6s 0.1s 1;
    -moz-animation: highlight 6s 0.1s 1;
	-ms-animation: highlight 6s 0.1s 1;
	-o-animation: highlight 6s 0.1s 1;
	animation: highlight 6s 0.1s 1;
}

@-webkit-keyframes highlight {
    0% { background-color: red; }
    100% { background-color: white; }
}
@-moz-keyframes highlight {
    0% { background-color: red; }
    100% { background-color: white; }
}
@-ms-keyframes highlight {
    0% { background-color: red; }
    100% { background-color: white; }
}
@-o-keyframes highlight {
    0% { background-color: red; }
    100% { background-color: white; }
}
@keyframes highlight {
    0% { background-color: red; }
    100% { background-color: white; }
}
