Breadcrumbs on ordinary post type

Breadcrumbs on ordinary post type

Breadcrumbs will displaying an information such as: a link to your home (main page), category of the post, the post name (optional).

These days, almost all premium theme have this feature. But, how about custom post type? Do they have something like this? The answer is yes, custom post type can have a breadcrumbs also since the base is the ordinary post.

Not all premium theme have this feature (breadcrumbs for custom post type), you have to install a plugin to do it.

At this post, i will share some codes that can make you don’t have to install a plugin in order to displaying the breadcrumbs.

This code will displaying the breadcrumbs for custom post type or the ordinary post.

To do it, copy and paste this code below to your functions.php file:

function my_breadcrumbs() {

	/* === OPTIONS === */
	$text['home']     = 'Home'; // text for the 'Home' link
	$text['category'] = 'Archive by Category "%s"'; // text for a category page
	$text['search']   = 'Search Results for "%s" Query'; // text for a search results page
	$text['tag']      = 'Posts Tagged "%s"'; // text for a tag page
	$text['author']   = 'Articles Posted by %s'; // text for an author page
	$text['404']      = 'Error 404'; // text for the 404 page

	$show_current   = 1; // 1 - show current post/page/category title in breadcrumbs, 0 - don't show
	$show_on_home   = 0; // 1 - show breadcrumbs on the homepage, 0 - don't show
	$show_home_link = 1; // 1 - show the 'Home' link, 0 - don't show
	$show_title     = 1; // 1 - show the title for the links, 0 - don't show
	$delimiter      = ' » '; // delimiter between crumbs
	$before         = '<span class="current">'; // tag before the current crumb
	$after          = '</span>'; // tag after the current crumb
	/* === END OF OPTIONS === */

	global $post;
	$home_link    = home_url('/');
	$link_before  = '<span typeof="v:Breadcrumb">';
	$link_after   = '</span>';
	$link_attr    = ' rel="v:url" property="v:title"';

		}

		echo '</div><!-- .breadcrumbs -->';

	}
}

Then to call your breadcrumbs, put this code at your single.php file:

<?php if (function_exists('my_breadcrumbs')) my_breadcrumbs(); ?>

And done!

  1. After digging through many examples on the web, this one worked the best for me and is highly recommendable when using custom post types. Thank you very much!

    • Update. I dug in and added a span class to wrap the “Page 2” and make it look right but I’d rather the breadcrumbs execute like “Home / Campaigns / Page 2” (in my case) if possible, linking the “Categories” in a link back to page 1. Anybody?

      • Hi,

        You can find out this code at your function.php file:

        if ($show_current == 1) echo $before . sprintf($text['category'], single_cat_title('', false)) . $after;
        

        Modify it become:

        if ($show_current == 1) echo $before . '<a href="'. get_category_link($this_cat->term_id) .'">' . sprintf($text['category'] . '</a>', single_cat_title('', false)) . $after;
