I have three different Custom Post Types:

  1. Company
  2. Employee
  3. Project

They are connected with ACF relationship fields so as the Company can have multiple Employees and each Employee can have a project attached. The get_field() function retrieves attached post objects to create some sort of relationship.

What I need to do is create three permalink structures for these CPT:

  1. For Companies: www.somepage.com/%company_name%
  2. For Employees: www.somepage.com/%company_name%/%employee_name%
  3. For Projects: www.somepage.com/%company_name%/%employee_name%/%project_name%

What I have already managed to do is to set permalink structure to them with this piece of code:

function dd_custom_permalinks($permalink, $post, $leavename) {
    $post_id = $post->ID;
    if(($post->post_type != 'project' && $post->post_type != 'employee' && $post->post_type != 'company') || empty($permalink) || in_array($post->post_status, array('draft', 'pending', 'auto-draft')))
        return $permalink;

    if (get_field("employees", $post->ID)) {
        $permalink = str_replace('%company%', $post->post_name, $permalink);
    } elseif (get_field("company", $post->ID)) {
        $permalink = str_replace('%company%', get_field("company", $post->ID)[0]->post_name, $permalink);
        $permalink = str_replace('%employee%', $post->post_name, $permalink);
    } elseif (get_field("employee", $post->ID)) {
        $employee= get_field("employee", $post->ID)[0];
        $company= get_field("company", $employee->ID)[0];
        $permalink = str_replace('%company%', $company->post_name, $permalink);
        $permalink = str_replace('%employee%', $employee->post_name, $permalink);
        $permalink = str_replace('%project%', $post->post_name, $permalink);
    }

    return $permalink;
}
add_filter('post_type_link', 'dd_custom_permalinks', 10, 3);

The problem is I cannot find a way to make them valid, as the structure always leads to Company (first part of the custom url structure). Probably I have to bind the further with the CPT query somehow?

I have also tried using custom rewrite rules, but I can't understand how should this be done to be fair. Here's what I got so far (not working):

function dd_custom_rewrite_rules() {
    add_rewrite_tag('%company%', '([^/]+)', 'company=');
    add_permastruct('company', '/%company%', false);
    add_rewrite_rule('^company/([^/]+)/([^/]+)/?','index.php?company=$matches[2]','top');

    add_rewrite_tag('%employee%', '([^/]+)', 'employee=');
    add_permastruct('employee', '/%company%/%employee%', false);
    add_rewrite_rule('^employee/([^/]+)/([^/]+)/?','index.php?employee=$matches[2]','top');
    
    add_rewrite_tag('%project%', '([^/]+)', 'project=');
    add_permastruct('project', '/%company%/%employee%/%project%', false);
    add_rewrite_rule('^project/([^/]+)/([^/]+)/?','index.php?project=$matches[2]','top');

}
add_action( 'init', 'dd_custom_rewrite_rules' );

Any ideas how (or maybe IF) can I get this to work properly?

    One way to prevent the issue is by using the actual "company" slug in the rewrite rule's RegEx pattern, e.g. ^company/(foo|bar-baz)/([^/]+)/? which would match example.com/company/foo/.. and example.com/company/bar-baz/... But you'll need to ensure the slug is in sync with the current one in the posts table, so if foo was later on changed to foo-inc, then the same needs to be done on the rewrite rule.

Sally CJ commented an important detail that helped me reach what I needed.

Apart from that I struggled with what seemed to be regex error - one of my rules was overriding another because there was no $ character in regex to end the string.

Working solution for custom rewrites:

function dd_custom_rewrite_rules() {
    add_rewrite_tag('%company%', '([a-z0-9-]+)', 'company=');
    add_rewrite_tag('%employee%', '([a-z0-9-]+)', 'employee=');
    add_rewrite_tag('%project%', '([a-z0-9-]+)', 'project=');

    add_permastruct('project', '/company/%company%/%employee%/%project%', false);
    add_permastruct('employee', '/company/%company%/%employee%', false);
    add_permastruct('company', '/company/%company%', false);

    add_rewrite_rule('^company[/]%company%[/]?','index.php?company=$matches[1]','top');
    add_rewrite_rule('^company[/]([a-z0-9-]+)[/]([a-z0-9-]+)[/]?$','index.php?employee=$matches[2]','top');
    add_rewrite_rule('^company[/]([a-z0-9-]+)[/]([a-z0-9-]+)[/]([a-z0-9-]+)[/]?$','index.php?project=$matches[3]','top');
