WordPress allowed to register new user and also you can define user role. Many wp blog site allow user to get registration on their site.
But many time we want, when user go for registration on the site then after complete registration they will go to a specific page for example – thank you page. for this you just add a simple code to your function.php file and type the url or page path where you want to redirect the user.
code below :
return home_url( '/thank-you/' );
add_filter( 'registration_redirect', 'wp_registration_redirect' );
