Taxonomy Terms in Breadcrumbs
I think, there are three different options:
- if the taxonomy isn’t hierarchical,
- if the taxonomy is hierarchical but only one term of taxonomy could be checked in posts,
- if the taxonomy is hierarchical and all terms from the tree could be checked in posts.
Non-hierarchical taxonomy
Such taxonomies works like post tags. The simpliest way to print the term links is the_terms()
function.
global $post; // this will help if you would use this code inside a custom function
$rd_post_id = $post->ID; // current post ID
$rd_taxonomy = 'region'; // taxonomy name
// the third argument is what you want to add before the navigation, you can leave it empty
// the fourth argument is term link separator , | / •
the_terms( $rd_post_id, $rd_taxonomy, 'Navigation: ', ' / ' );
Taxonomies with hierarchy
These taxonomies works like categories.
1. When only one term is checked
the_terms()
functions will work great with this, so, look at the previous code example.
2. When the term tree is checked
This is how it looks:

In that case the right term order is very important for us.
echo '<div id="kroshki">You are here:';
$rd_taxonomy = 'region'; // region taxonomy
$rd_terms = wp_get_post_terms( $post->ID, $rd_taxonomy, array( "fields" => "ids" ) ); // getting the term IDs
if( $rd_terms ) {
$term_array = trim( implode( ',', (array) $rd_terms ), ' ,' );
$neworderterms = get_terms($rd_taxonomy, 'orderby=none&include=' . $term_array );
foreach( $neworderterms as $orderterm ) {
echo '<a href="' . get_term_link( $orderterm ) . '">' . $orderterm->name . '</a> » ';
}
}
the_title();
echo '</div>';

Thank you very much for posting this code! Works a charm.
How difficult would it be to remove the final part which combines all the terms together i.e. just the terms show?
You’re welcome!
I don’t understand what you mean :)
THANK YOU !!! This worked GREAT after looking for HOURS!!
Hello, is it possible to show only the one taxonomy term that was clicked? This shows all the taxonomy terms in the taxonomy, not just one.
Hello,
What do you mean by “that was clicked” ?
Hello! my taxonomies are set up like this:
Processing type:
Type 1
Type 2
Type 3
If I have a post that is tagged with Processing type: Type 1, the “Type 1” links back to its taxonomy page to show other Type 1 posts. I want to show a breadcrumb that indicates that they have clicked on Type 1. But, the code above shows Type 1, Type 2, and Type 3, even though Type 1 was clicked. I would like to show only Type 1 in the breadcrumb :) any ideas?
Hi – I figured it out, thanks :)
It would be great if you share your solution here 🙃
Turns out it was pretty simple, so I’m a bit embarrassed:
Thanks for sharing!
perfect
You saved me :)
Thanks a Lot!
