Setting up a personal account, how to do it?

Question

Online shopping

I am creating an online store, in the header of the site there is "Authorization" and "Registration", is it possible to make it so that after Authorization by the user he is transferred to the main page and instead of "Authorization" and "Registration" he sees something like "You are authorized as : <username>"

Answer 1

if ( is_user_logged_in() ) {
  echo 'Вы авторизованы на сайте!';
тут пишешь строчку для редиректа на главную
}
else {
  echo 'Вы всего лишь пользователь!';
}

in the menu where registration and authorization you write like this

if ( is_user_logged_in() ) {
 global $current_user;
  wp_get_current_user() ;
   
  echo 'Вы авторизованы на сайте как '. $current_user->user_login;
}
else {
   вывод кнопок авторизация регистрация
}
