I have a scenario in which the intention is to make custom permalink that can be changed dynamically, for example:

  • If a country information is showing up then the URL should be http://example.com/country-information

  • If the city information of that specific country is showing up then the URL should be like http://example.com/country/city-information.

How can I achieve that?

  • Are cities and countries custom post types?

    Yeah! They were meant to be custom post types but i had managed to do in another way by doing some URL rewriting.

It depends on what you mean by "changed dynamically", but the simplest way to achieve what you're talking about is to use pages (or a hierarchical custom post type), and make the "city-information" pages into children of the "country-information" page they are associated with. Then set permalinks to "Post Name", and you'll get the urls you're looking for.

  • By involving some jQuery to avoid "page refresh" every time. Sorry! I was away but I was able to achieve that back then with URL Rewriting, and got that hierarchical order you have said! Thanks for the help btw :)

Did you try add_rewrite_rule()? For example:

add_action( 'init',  function() {
    add_rewrite_rule( 'country-information/([a-z0-9-]+)[/]?$', 'index.php?country-information=$matches[1]', 'top' );
} );

After adding the new rule, you have to flush the permalink, Admin > Permalinks > Save

Then add a new query var via add_filter, needed to allow custom rewrite rules using your own arguments to work, or any other custom query variables you want to be publicly available.

add_filter( 'query_vars', function( $query_vars ) {
    $query_vars[] = 'country-information';
    return $query_vars;
} );

You can also use a custom particular template for that permalink using template_include hook.

function conutry_information_template( $template ) {
    if ( get_query_var( 'country-information' ) === false || get_query_var( 'country-information' ) == '' ) {
        return $template;
    }
 
    return get_template_directory() . '/country-information.php';
}
add_action( 'template_include', 'conutry_information_template' );
