   This action will allow us to set a cookie in the headers but still have access to the WP class object. This example will show you how to set a cookie if you are on a specific page ID.

   function wpdocs_set_cookie() {
     // using is_page conditional for specific page ID
     if ( is_page( 126 ) ) {
       setcookie( "wpdocs-my-custom-cookie", "true", time() + ( YEAR_IN_SECONDS * 5 ), COOKIEPATH, COOKIE_DOMAIN, false ); 
     }
   }
   
   add_action( 'wp', 'wpdocs_set_cookie' );
