Remove the Parent Slug in a CPT URL

    Hello,

    Here is the code that I insert in my functions.php to remove the slug of a CPT present in the URL :

    /**
 * Remove the custom post type slug from URL
 */
function wpc_remove_cpt_slug($post_link, $post, $leavename) {
	if ('SLUG' != $post->post_type || 'publish' != $post->post_status) {
		return $post_link;
	}
	$post_link = str_replace( '/' . $post->post_type . '/', '/', $post_link );
	return $post_link;
}

add_filter('post_type_link', 'wpc_remove_cpt_slug', 0, 3); 

function wpc_parse_request_trick($query) {
	if (! $query->is_main_query())
	return;

	if (2 != count($query->query) || ! isset($query->query['page'])) {
		return;
	}

	if (! empty( $query->query['name'])) {
		$query->set('post_type', array('post', 'SLUG', 'page'));
	}
}

add_action('pre_get_posts', 'wpc_parse_request_trick');

    I have been using this for several years and it works perfectly for the need in question.

    I currently need to create a parent/child relationship with a CPT while keeping short URLs of the form domainname.fr/title-publication/

    I use CPT UI to create my CPTs. I have selected “true” in Hierarchy allowing me to have parent-child relationships for the CPT in question.

    Let’s take an example with a car brand as a parent and a model as a child.

    I obtain the URL for the child CPT: nomdedomaine.fr/tesla/model-3/

    But I need this : nomdedomaine.fr/model-3/

    Being not at all an experienced developer, I did my research and adapted the following code that I always inserted in functions.php :

    /**
 * Remove the parent custom post type slug from URL
 */
function df_custom_post_type_link( $post_link, $id = 0 ) {  
    $post = get_post($id);  
    if ( is_wp_error($post) || 'SLUG' != $post->post_type || empty($post->post_name) )  
        return $post_link;  
    return home_url(user_trailingslashit( "$post->post_name" ));  
}
add_filter( 'post_type_link', 'df_custom_post_type_link' , 10, 2 );

function df_custom_rewrite_rule() {
    add_rewrite_rule('(.*?)$', 'index.php?news=$matches[1]', 'top');
}
add_action('init', 'df_custom_rewrite_rule');

    My children’s CPTs have a correct URL with: nomdedomaine.fr/model-3/

    But as soon as I make changes in the Back-Office such as adding content or deleting content or creating a new menu, I then have a big incomprehensible bug such as all my URLs start having a redirection to the homepage, I mean nomdedomaine.fr.

    I would like to make it clear that this is really all my URLs in their entirety, I mean not just the URLs of the CPT in question.

    Has anyone ever succeeded in correctly removing the parent slug in a CPT URL ?

    Many thanks in advance

  • Hello,

    I’m not sure there’s a good way to do what you’re describing with having weird side effects like those you’ve already experienced.

    In your car example above, it seems to me that your parent “Tesla” post is being used more as a category than as an actual post. So one other option would be to scrap the hierarchical scheme and create a custom “Brand” taxonomy instead. That way your “Model 3” post wouldn’t have the extra segments in the URL, but you’d still be able to group multiple models under one brand.

    @corey : Thanks for your reply

    I know that is a bit strange but I need to use CPT hierarchical structure.

    I finally succed to do it by usiing this code :

    /**
 * Remove the parent custom post type slug from URL
 */
function wpse_101072_flatten_hierarchies( $post_link, $post ) {
    if ( 'CPT-NAME' != $post->post_type )
        return $post_link;

    $uri = '';
    foreach ( $post->ancestors as $parent ) {
        $uri = get_post( $parent )->post_name . "/" . $uri;
    }

    return str_replace( $uri, '', $post_link );
}
add_filter( 'post_type_link', 'wpse_101072_flatten_hierarchies', 10, 2 );
