How to Change Permalink Structure for Custom Post Type/Taxonomy

Permalinks on a site are crucial, specially for Search Engine Optimization. Let’s say you have a custom post type named as directory and its default URL structure is www.mysite.com/directory/directory-name. But you want to change it by adding the category base of custom post type. So, after the change it should be something like www.mysite.com/directory/my-category/directory-name.

In order to change the permalink structure, first and foremost thing is to change the value of ‘rewrite’ parameter where your custom post type is being registered. It should be like:

‘rewrite’ => array(‘slug' => ‘directory/%directory-category%');

1	‘rewrite’ => array(‘slug' => ‘directory/%directory-category%');

Here ‘directory-category’ is the slug of category/taxonomy of the custom post type named ‘directory’.

After implementing the change described above, you need to add the following code in your Theme’s/Child Theme’s functions.php file:

function pt_wpa_course_post_link( $post_link, $id = 0 ){
         $post =get_post($id);
         if ( is_object( $post ) ){
         $terms = wp_get_object_terms( $post->ID, ‘directory-category’);
if( $terms ){
                 return str_replace( '%directory-category%' , $terms[0]->slug , $post_link );
}
}
return $post_link;
}
add_filter( 'post_type_link', 'pt_wpa_course_post_link', 1, 3 );

function pt_wpa_course_post_link( $post_link, $id = 0 ){

$post =get_post($id);

if ( is_object( $post ) ){

$terms = wp_get_object_terms( $post->ID, ‘directory-category’);

if( $terms ){

return str_replace( '%directory-category%' , $terms[0]->slug , $post_link );

}

return $post_link;

}

add_filter( 'post_type_link', 'pt_wpa_course_post_link', 1, 3 );

This code will lead to the change required in permalink structure of your custom post type including the category/taxonomy in it.
