Embedding a Bibtex publication list in a website with PHP

Now that I have a more professional website, I wanted to include on it a list of publications. It took me a while to figure out a "good" way to do this, and many things I tried didn't work, so here's the solution I eventually settled on.

Maybe it can help you too!

My list of publications, though not huge yet, is stored in Bibtex format. I wanted a way to embed that nicely on a website.  Since the same bibtex files feed other documents, I didn't really want to retype them in HTML markup. Instead I wanted something which would take the data directly out of the Bibtex files and put it in a format where I could use CSS to style it myself.

Some options I found after searching for a while:

  • Bibbase.org would probably actually be fine. It takes a Bibtex file hosted anywhere, and transforms it into a fancy, viewer-sortable, CSS-stylable list. It allows this list to be embedded via PHP, Javascript or frame into another webpage. The only reason I didn't take this, is that I couldn't find a way to control how it looked (except CSS), and the list seems to be built using Ajax, which is really unnecessary imo. I think overuse of Ajax is a scourge on the web :) That said, it is super easy to use and probably the best solution for most people.
  • There are a number of static Bibtex-to-html tools, such as bibtex2html, and tex2_rst_html, the latter of which actually looked pretty good, but in trying to install it it led me down a pip-chain of dependencies which ended in a 404, so I had to give up.
  • There are some Latex bibliography styles which render Bibtex bibliographies as HTML. I couldn't get any of them to work especially easily and most require editing XSLT or Bibtex style files to change how they look. Besides, while a static Bibtex-to-XML/HTML converter would have been OK, I'd much prefer a live PHP-driven converter.
  • PhpBibLib looked perfect, but I just couldn't get it to do what I wanted, and I don't know PHP well enough to do proper debugging.

Eventually I found:

For the PHP-semi-literate (such as myself), you use it like this:

  1. Upload the files somewhere visible from the PHP page in which you want your publication list.
  2. At the top of your PHP page, add
    <?php include 'bibtexParse/PARSEENTRIES.php' ?>
    <?php include 'bibtexParse/PARSECREATORS.php' ?>

    Where the paths indicate where you uploaded the files.

  3. ParseEntries() will take a .bib file and convert it into a PHP array. It is invoked like this:
    $parse = NEW PARSEENTRIES();
    $parse->expandMacro = FALSE;
    $parse->removeDelimit = TRUE;
    $parse->fieldExtract = TRUE;
    list($preamble, $strings, $entries, $undefinedStrings) = $parse->returnArrays();

    Where the meaning of the various parameters can be found in the documentation.

  4. Then, $entries is a PHP array of bib entries which can be listed in the following way:
    <?php foreach ( $entries as $entry ) { ?>
    	<li class="publication">
    		<?php $title = $entry["title"]; ?>
    		<span class="publication-title"><?php print($title); ?></span>
    <?php } ?>


  5. ParseCreators() also allows the conversion of the and-delimited list of authors in a Bibtex entry into a PHP array of author names:
    $creator = new PARSECREATORS();
    foreach ( $entries as $entry ) { ?>
    <span class="publication-authors">
    	$authors = $creator->parse($entry["author"]);
    	$author_full_names = array();
    	foreach ($authors as $author) {
    		$author_full_name = implode(' ', $author);
    		$author_full_names[] = $author_full_name;
    	$author_full_names = array_map('trim', $author_full_names);
    	$author_list = implode(', ', $author_full_names);
    	print($author_list); ?>
    <?php } ?>
  6. Since the markup is user-written, the style of the publication can be chosen at will, and can be formatted using CSS.
  7. ParseEntries() looks like it will do a bunch of Bibtex-supported things like macros and strings (which I don't use), and also has the benefit that it can parse arbitrary "unsupported" fields. So I used a pdf = {path/to/file.pdf} field in my bibliography to include a link to a file, and a doi = {doi} field to automatically produce a link to the publication's DOI.

Because it's live-rendered in PHP, it would be straightforward enough to have it automatically render me a CV if I wanted.  Problem solved.

I'm currently using it to generate a couple of pages on my site.
