Getting the user_id from pdb_single template

I’m using the following routine to get the user_id using the pdb_single shortcode.

I’m using a single record link field to link to the single record.

$user_id = do_shortcode(‘[pdb_single template=”single-value” fields=”id”]’);

Although it works, I’m sure its not the best way to do this.

Can you help please

Thank you.
