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>

Simple yet powerful breadcrumbs for geeks

Instant Breadcrumbs adds a breadcrumb trail to your WordPress blog’s primary navigation menu. No theme editing required! 
Including a breadcrumb trail on your site not only makes it easier for visitors to navigate your site, but also allows 
search engines to better explore your blog and include the breadcrumb information in rich snippet data in search 
results. Many breadcrumb plugins exist, but normally require either theme editing, or use of a theme that is already 
customized to include the breadcrumb function. In addition, editing the theme is usually followed by some CSS 
styling to make the breadcrumb trail match the overall ‘look’ of the site.
Instant Breadcrumbs takes a different approach. Since breadcrumbs are a navigation aid, the generated trail is 
automatically added to the front of your existing primary navigation menu. This allows it to not only function 
straight out of the box with a large number of themes, but also use the existing styling of your primary navigation 
menu.
A quick overview of Instant Breadcrumbs features:
<ul>
<li>Works with both custom primary menus and the default ‘page’ menu generated by WordPress;</li>
<li>Produces RDFa-compliant breadcrumb trails that may be used by Google and others in search results;</li>
<li>Supports customization of the breadcrumb titles for pages such as the front page, archives, and search;</li>
<li>Re-uses existing top-level entries in the primary menu to avoid repeated links;</li>
<li>Includes CSS classes for added breadcrumbs for optional further styling if desired;</li>
<li>Use the built-in breadcrumb generator, or third-party generators such as Yoast (<a href="https://wordpress.org/plugins/wordpress-seo/" rel="ugc">WordPress SEO</a>) 
and <a href="https://wordpress.org/plugins/breadcrumb-navxt/" rel="ugc">Breadcrumb NavXT</a>, adding those to the nav menu without theme editing. Tested against 
Breadcrumb NavXT 5.1.0 and WordPress SEO 1.5.4.2;</li>
<li>Supports HTML markup in post titles, with the option to disable it;</li>
<li>“Manual” mode allows insertion into templates for themes that do not use the WordPress primary navigation menu;</li>
<li>A widget is available if you would prefer to show the breadcrumb trail in a sidebar.</li>
</ul>
