I have modified your code a bit:

<?php

function yafootnotes($data){
$debug = true;
$before_anchor = '[';//opening the anchor
$after_anchor = ']';//closing the anchor
$footnotes_title = 'FOOTNOTES';//the title to display before the footnotes on the bottom
$foots = array();
preg_match_all("/\{\{([0-9]*):([^}]*)\}\}/", $data, $foots);//finding anchors in the text
$data .= '’.print_r($foots).”;
if(count($foots[0]) != 0){//there are footnotes to process!
$count = 0;
foreach($foots[1] as $foot){//finding the footnotes in the text
$data = str_replace(‘{{‘.$foots[1][$count].’:’.$foots[2][$count].’}}’, ‘‘.$before_anchor.$foots[1][$count].$after_anchor.’‘, $data);
//$data .= ‘xx’.$foot[$count].’:’.$foots[2][$count].’xx‘;

$count += 1;
}
//$data .= ‘yy’.print_r($foots).’yy’;
$data .= ”.$footnotes_title.”;
$count = 0;
foreach($foots[2] as $foot_text){
$data .= ‘‘.$foots[1][$count].’. ’.$foot_text.’↑‘;
$count += 1;
}

}
return $data;
}
add_filter(‘the_content’, ‘yafootnotes’, 1, 1);

# usage {{1:footnotetext}} blah blah {{2:footnote other text}} etc.

?>

After inspecting all the other “footnotes” plugins available for wordpress, we decided yours is the best.
We are now using it on our website with some modifications to suit our needs; e.g. multiple references to the same book, highlighting.

Again, thank you and keep up the good work!

We’ve run into another issue. Law review articles often have multiple paragraphs in a footnotes (yeah, I know it is a bit excessive but I can’t change that!). However, multiple paragraphs in a footnote (between the footnote tags) causes the footnote text to also be in the body of the article. Is there anything I should be doing to prevent this?
