[FIXED] how to remove custom post type from wordpress url?

Issue

I have a wordpress website which is using the custom template with custom post types like landing and services.

Each post type have a specific slug in the url like this => (http://example.com/landing/landing-page-name)

I want to change this url (http://example.com/landing/landing-page-name) to this url (http://example.com/landing-page-name).

In fact I need to remove the [landing] phrase from the url. The important thing is that the [landing] is a custom post type in my posts table.

I have tested following solutions:

==> I have changed slug to '/' in rewrite property in register_post_type() --> It breaks the all of landings, posts and pages url (404)

==> I added 'with_front' => false to the rewrite property --> nothing changed

==> I tried to do this with RewriteRule in htaccess --> it did not work or give too many redirects error

I could not get a proper result.

Did anyone solve this problem before?

Solution

First, you need to filter the permalink for your custom post type so that all published posts don't have the slug in their URLs:

function stackoverflow_remove_cpt_slug( $post_link, $post ) {
    if ( 'landing' === $post->post_type && 'publish' === $post->post_status ) {
        $post_link = str_replace( '/' . $post->post_type . '/', '/', $post_link );
    }
    return $post_link;
}
add_filter( 'post_type_link', 'stackoverflow_remove_cpt_slug', 10, 2 );

At this point, trying to view the link would result in a 404 (Page Not Found) error. That's because WordPress only knows that Posts and Pages can have URLs like domain.com/post-name/ or domain.com/page-name/. We need to teach it that our custom post type's posts can also have URLs like domain.com/cpt-post-name/.

function stackoverflow_add_cpt_post_names_to_main_query( $query ) {
    // Return if this is not the main query.
    if ( ! $query->is_main_query() ) {
        return;
    }
    // Return if this query doesn't match our very specific rewrite rule.
    if ( ! isset( $query->query['page'] ) || 2 !== count( $query->query ) ) {
        return;
    }
    // Return if we're not querying based on the post name.
    if ( empty( $query->query['name'] ) ) {
        return;
    }
    // Add CPT to the list of post types WP will include when it queries based on the post name.
    $query->set( 'post_type', array( 'post', 'page', 'landing' ) );
}
add_action( 'pre_get_posts', 'stackoverflow_add_cpt_post_names_to_main_query' );
