I have an issue when it come to displaying the custom post type category in my breadcrumb menu on the page it looks something like the following

Home / / Post Title

when it should be

Home / Custom Cat Name / Post Title

It shows the post on the page and the posts title but not the category?

Breadcrumb menu code:

            /*********************
            breadcrumbs menu
            *********************/
            function the_breadcrumb(){
                echo '<ul class="crumbs">';
                if (!is_home()){
                    echo '<li><a href="';
                    echo get_option('home');
                    echo '">';
                    echo 'Home';
                    echo '</a></li><li class="separator"> &#124; </li>';
                    if (is_category() || is_single('post')){
                        echo '<li>';
                        the_category(' </li><li class="separator"> &#124; </li><li> ');
                        if (is_single()){
                            echo '</li><li class="separator"> &#124; </li><li>';
                            the_title();
                            echo '</li>';
                        }
                    } elseif (is_page()){
                        echo '<li>';
                        echo the_title();
                        echo '</li>';
                    }
                }
                elseif (is_tag()){
                    single_tag_title();
                }
                elseif (is_day()){
                    echo"<li>Archive for "; the_time('F jS, Y'); echo'</li>';
                }
                elseif (is_month()){
                    echo"<li>Archive for "; the_time('F, Y'); echo'</li>';
                }
                elseif (is_year()){
                    echo"<li>Archive for "; the_time('Y'); echo'</li>';
                }
                elseif (is_author()){
                    echo"<li>Author Archive"; echo'</li>';
                }
                elseif (isset($_GET['paged']) && !empty($_GET['paged'])){
                    echo "<li>Blog Archives"; echo'</li>';
                }
                elseif (is_search()){
                    echo"<li>Search Results"; echo'</li>';
                }
                echo '</ul>';
            }

  • Please properly intend your code, you making it very difficult for others who might be able to help you to read and keep track of your code – Pieter Goosen Aug 29 '14 at 10:19
  • Sorry, edited it now – Nsokyi Aug 29 '14 at 10:30
  • On a sidenote, I think is_single('post') should actually be is_singular('post') - is_single() Codex and is_singular() Codex – Howdy_McGee Aug 29 '14 at 13:58
  • Are you using build in categories or an custom taxonomy. See here Do you need to display the category/term assigned to the post in single view and/or do you need to show the category/taxonomy/term name on the category/taxonomy page – Pieter Goosen Aug 30 '14 at 5:59
  • Just another thing, the_category won't work outside the loop. You should look at get_the_category instead – Pieter Goosen Aug 30 '14 at 6:59

I'm still not one hundred percent sure where and what needs to be displayed.

If you need to show the current single post's category, you'll need to use get_the_category in stead of the_category as the_category needs to be called inside the loop. You can use get_the_category as follow (Remember to use the global $post to retrieve the post ID)

<?php
global $post;
$categories = get_the_category($post->ID);
var_dump($categories);
?>

If you need to get the category name on a category page, you can use get_query_var('cat') to retrieve info about the current category page.

Here is an example of the breadcrumbs that I use on my site.

if ( ! function_exists( 'pietergoosen_breadcrumbs' ) ) :

    function pietergoosen_breadcrumbs() {
          /* === OPTIONS === */
        $text['home']     = _x( 'Home', 'Home', 'pietergoosen' ); // text for the 'Home' link
     $text['category'] = __( 'Archive by Category "%s"', 'pietergoosen' );  // text for a category page
     $text['search']   = __( 'Search Results for "%s" Query', 'pietergoosen' ); // text for a search results page
     $text['tag']      = __( 'Posts Tagged "%s"', 'pietergoosen' );  // text for a tag page
     $text['author']   = __( 'Posts Posted by %s', 'pietergoosen' ); // text for an author page
     $text['404']      = __( 'Error 404', 'pietergoosen' );  // 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      = ' &raquo; '; // delimiter between crumbs
     $before         = '<span class="current">'; // tag before the current crumb
     $after          = '</span>'; // tag after the current crumb
     /* === END OF OPTIONS === */
