get_term_by(), but it doesn’t now, which is why I did it this way.
With that said, here’s the code. Place this in your functions.php file (or custom_functions.php for Thesis):

<div id="LC3">function be_taxonomy_breadcrumb() {</div>
<div id="LC4">// Get the current term</div>

| Added: Taken from Bill Ericson: http: //www.billerickson.net/wordpress- taxonomy-breadcrumbs/ | |||
| Added: This post has been marked as <strong>old</strong>. The code might no longer work. Comments have been disabled as this is no longer maintained. Use the search on the right to find a newer tutorial. | |||
| Added: I’m working on a project right now that uses hierarchical taxonomies, and the client requested a breadcrumb along the top. I searched online but couldn’t find any good existing plugins, so thought I’d write my own. | |||
| Added: Note: This was built for WordPress 3.03. WordPress 3.1 (hopefully coming out this month) will add a lot of features to taxonomies, including hierarchical URLs. This solution is NOT designed for hierarchical URLs. If you read through the code you’ll see I’m assembling them with 3 things: | |||
| Deleted: | Added: <ul> | ||
| Added: <li><code>bloginfo( 'url')</code> – This is the URL for your site</li> | |||
| Added: <li><code>$item- >taxonomy</code> – This is the name of the taxonomy the term is in</li> | |||
| Added: <li><code>$item- >name</code> – This is the name of the taxonomy term</li> | |||
| Added: </ul> | |||
| Added: Since WordPress doesn’t currently support hierarchical URLs for taxonomies, no matter how deep your term is it will still have the url structure of yoursite.com/ taxonomy-name/ taxonomy-term. Hopefully 3.1 will give us a URL from <code>get_ term_by()</code>, but it doesn’t now, which is why I did it this way. | |||
