The plugin allows you to render breadcrumbs and configurate them with filters.
<h3>Usage</h3>
Use the function ‘jinx_breadcrumbs’ to render the breadcrumbs where you want them to be. You may overwrite the default arguments by passing an array to the function.
<pre><code><?php

 if (function_exists('jinx_breadcrumbs')) :

 jinx_breadcrumbs([
 // default args
 'home' => __('Home', 'jinx-breadcrumbs'),
 'search' => __('Search: "%s"', 'jinx-breadcrumbs'),
 '404' => __('Error 404', 'jinx-breadcrumbs'),
 'author' => __('Author: %s', 'jinx-breadcrumbs'),
 'year' => 'Y',
 'month' => 'F',
 'day' => 'd',
 'before' => '<nav aria-label="breadcrumb"><ol>',
 'after' => '</ol></nav>',
 'before_item' => '<li%s>',
 'after_item' => '</li>',
 ]);

 endif;

?>
</code></pre>
You may also use the filter ‘jinx_jinx_breadcrumbs’ to overwrite them.
<pre><code><?php

 add_filter('jinx_breadcrumbs', function($args) {

 return array_merge($args, [
 'home' => __('Start', 'cca'),
 'search' => __('Your searched for "%s"', 'cca'),
 ]);

 });

?>
</code></pre>
The plugin will automatically try to find the correct archive pages by using the rewrite slug of custom taxonomies and post types.
If you may want to change this behavior, you may use some filters to manipulate the archive page.
If you return NULL, the archive page will be removed.
<pre><code><?php

 // filters the archive page, passing the PID, type ('taxonomy' or 'post_type') and name (eg. 'video')
 add_filter('jinx_breadcrumbs_archive', function($pid, $type, $name) {

 return $pid;

 }, 10, 3);

 // filters the archive page, passing the PID and name (eg. 'video')
 // the type is part of the filter (eg. 'jinx_breadcrumbs_archive_taxonomy')
 add_filter('jinx_breadcrumbs_archive_{type}', function($pid, $name) {

 return $pid;

 }, 10, 2);

 // filters the archive page, passing the PID
 // the type and name are part of the filter (eg. 'jinx_breadcrumbs_archive_post_type_video')
 add_filter('jinx_breadcrumbs_archive_{type}_{name}', function($pid) {

 return $pid;

 }, 10, 1);

?>
</code></pre>

RDFa Breadcrumb provide links back to each previous page the user navigated through to get to the current page or – in hierarchical site structures – the parent pages of the current one.
It gives you a new template tag called <code>rdfa_breadcrumb()</code> that you can place anywhere in your template files. It has inbuilt RDFa content markup, so this will help Google to recognize and display the breadcrumbs on search results as well.
Check out the screenshots.
