I am building a custom post type and its respective custom taxonomy.
Here is the code:
add_action( 'init', 'register_my_types' );
function register_my_types() {
register_post_type( 'help',
array(
'labels' => array(
'name' => __( 'Help Manager' ),
'singular_name' => __( 'Help' )
),
'public' => true,
'has_archive' => true,
'rewrite' => array(
'slug' => 'help/%help_categories%',
'with_front' => true
)
)
);
register_taxonomy( 'help_categories', array( 'help' ), array(
'hierarchical' => true,
'label' => 'Help Categories',
'rewrite' => array(
'slug' => 'help',
'with_front' => true
)
)
);
}
I am the doing a rewrite to include this in one pretty URL:
function so23698827_add_rewrite_rules( $rules ) {
$new = array();
$new['help/([^/]+)/(.+)/?$'] = 'index.php?help=$matches[2]';
$new['help/(.+)/?$'] = 'index.php?help_categories=$matches[1]';
return array_merge( $new, $rules ); // Ensure our rules come first
}
add_filter( 'rewrite_rules_array', 'so23698827_add_rewrite_rules' );
/**
* Handle the '%project_category%' URL placeholder
*
* @param str $link The link to the post
* @param WP_Post object $post The post object
* @return str
*/
function so23698827_filter_post_type_link( $link, $post ) {
if ( $post->post_type == 'help' ) {
if ( $cats = get_the_terms( $post->ID, 'help_categories' ) ) {
$link = str_replace( '%help_categories%', current( $cats )->slug, $link );
}
}
return $link;
}
add_filter( 'post_type_link', 'so23698827_filter_post_type_link', 10, 2 );
I want to include any sub category in the URL. So for example, I have the following structure:
- Custom Post Type
- Main Category
- Sub Category
- Sample Post
- Sub Category
- Main Category
The URL structure should be the following www.domain.com/custom_post_type/main-category/sub-category/sample-post
Can you help me achieve the above please
