Redirect a page based on last word in slug

I have a couple custom post types registered = Staff, Properties

If I have a page with the slug archive-staff, how can I automatically redirect that page to the Staff CPT archive page with a php function?

This should also work for any page that starts with “archive-“, automatically redirecting to the archive of any registered custom post type that matches the 2nd word of the slug.

So the custom archive-staff page would redirect to the Staff CPT archive page.

The custom archive-properties page would redirect to the Properties CPT archive page.

…and so on for for all custom post types only if their corresponding custom page exists.

There are many solutions for that..

1. .htaccess rules

You can put some redirect rules in your .htaccess file:

RewriteRule ^(.*)\-staff/$ /staff/? [L,R=301]
// some other rules

2. Using WordPress hooks

function my_redirect_function() {
    global $wp;

    if ( preg_match( '@staff/?$@', $wp->request ) ) {
        wp_redirect( get_post_type_archive_link( 'staff' ) );
        die;
    }

    // ... put other rules in here
}
add_action( 'template_redirect', 'my_redirect_function' );

3. Using Redirection plugin

You can use that plugin and define custom redirects based on regular expressions.
