Trailblaze

With Trailblaze, you can add breadcrumb navigational links to your WordPress theme by using the template tag, wap8_trailblaze(). This template tag can be added to the following templates:

• Archive Templates (categories, tags, post formats, custom post types, custom taxonomies, date based archives)
• Singular Templates (post, page, custom post type)
• Search Template
• 404 Template

For more information, please see this blog post.

You can install Trailblaze either via the WordPress Dashboard or by uploading the extracted trailblaze folder to your /wp-content/plugins/ directory. Once the plugin has been successfully installed, simply activate the plugin through the Plugins menu in your WordPress Dashboard.

Once the plugin has been activated, visit the Settings page to customize the Home link label and the breadcrumbs separator.

To add the template tag to your theme, insert the following code, preferably outside of the loop, where you would like the breadcrumb trail to appear.

<?php if ( function_exists( 'wap8_trailblaze' ) ) {
     wap8_trailblaze();
} ?>

The markup contains structured data for search engine optimization and contain class names for easy styling:

• The wrapping element is <nav class="breadcrumbs" itemprop="breadcrumbs">.
• The breadcrumb separator will be wrapped with <span class="crumb-separator">.
• The current, non anchored breadcrumb will be wrapped with <span class="current-crumb">.

Why was this plugin developed?

We found that we were reproducing this functionality for many of our clients and premium themes and thought it would be better suited as a freely available plugin instead of a theme template.

How do I add the template tag to my theme?

To add the template tag to your theme, insert the following code, preferably outside of the loop, where you would like the breadcrumb trail to appear.

<?php if ( function_exists( 'wap8_trailblaze' ) ) {
     wap8_trailblaze();
} ?>

Are there any known limitations?

Yes. Though we have added custom taxonomy archives to the breadcrumbs, the breadcrumbs will not return a hierarchical list when browsing a custom taxonomy archive that is hierarchical.
