Redirect Single Post CPT (Custom Post Type) to a specific URL

I have a domain domain.com and subdomain materials.domain.com

At the domain.com scope, I created a custom post type called resources and a portfolio grid (using Elementor) to display it’s featured image with the title.

When clicking on the grid item, the single post is shown for example: domain.com/resources/resource-title

I’d like to remove the single post from the domain and redirect on click to materials.domain.com/resource-title. I already have this page on the materialssubdomain).

How can I achieve that?

Method 1

Sometimes this would be achievable with add_rewrite_url but it looks like in this case it’s not as you need to redirect to a different domain.

In this case you need .htaccess or nginx rules to do this, so you need to add something like this to your nginx config for domain.com only, in order to rewrite those URLs:

rewrite ^/resources/(.+) https://materials.domain.com/$1 permanent;

You’ll likely need to restart nginx after you add this to the config file.

Happy to help if this doesn’t do exactly what you want. There’s more examples of nginx rewrite rules here: https://www.thegeekstuff.com/2017/08/nginx-rewrite-examples/

Method 2

If you want to do it from WordPress environment itself..

function wpse370481_redirect_url() {
    if ( is_singular( 'resources' ) ) {
        global $post;
    
        $path = $post->post_name;
        
        $redirect_url = 'https://materials.domain.com/' . $path;
        
        wp_redirect( $redirect_url );
        exit;
            
    }
}
add_action( 'template_redirect', 'wpse370481_redirect_url' );

Havn’t tested this code as I currently don’t have a setup to test this, but in theory, the code should work.
