<h1>Style Drupal 6's Taxonomy Lists with PHP, CSS and jQuery</h1>
<p class="posted text-light">5th April 2010</p>
<p>Whilst developing this, and other Drupal websites for clients, I decided that I wanted to categorise content using the taxonomy system. However, I wasn't happy with the way that Drupal displayed the terms lists by default, and I started comparing this to other websites that I look at.</p>
<p>To start with, I wanted to have something that described what the list was displaying - like in the second example above. I wanted to have the words 'Posted in' displayed before the list of terms. To do this, I had to edit the node template file that exists within my theme folder (sites/all/themes). As I only wanted this change to affect my Blog posts, the file that I needed to change is <strong>node-blog.tpl.php</strong></p>
<p>I scrolled down until I found the piece of code that displayed the terms list:</p>
<pre><code class="language-php"><?php if ($terms): ?>
<div class="terms terms-inline">
<?php print t('Posted in') . $terms; ?>
</div>
<?php endif; ?>
</code></pre>
<p>Adding <code>print t(' Posted in ')</code> will print the words 'Posted in' before outputing the terms.</p>
<p>I then added some CSS to re-size the spacing between the items, and then add the commas between them to seperate them:</p>
<pre><code class="language-css">.terms ul.links li {
margin-right: 1px;
padding: 0;
}
.terms ul.links li:after {
content: ",";
}
.terms ul.links li.last:after {
content: ".";
}
</code></pre>
<p>I created a file named <strong>script.js</strong> in my theme folder with the following code in it. After clearing Drupal's caches, this file is automatically recognised by Drupal 6.</p>
<pre><code class="language-js">if (Drupal.jsEnabled) {
$(document).ready(function() {
$('.terms ul.links li.last').prev().addClass('test');
})
}
</code></pre>
<p>This code finds the last item in the list, uses <strong>.prev</strong> to select the one before it, and then uses <strong>.addClass</strong> to assign it the HTML class of "test". We can then use this class to target it with specific CSS.</p>
<pre><code class="language-css">.terms ul.links li.test:after {
content: " and";
}
</code></pre>
