How to give access to only four records, open the rest only after payment?

Question

Payment systems

Hello! Please advise how to make it so that only 4 records are available to the user, and after payment everything else? What plugin to use?

Answer 1

It can be done without a plugin. Create a user role "Pro" for example, assign after payment.

add_action( 'after_switch_theme', 'add_pro_role' );
function 'add_pro_role() {
   add_role( 'pro', 'Pro', ['read' => true]);
}

// далее простая функция для вывода роли

function get_user_role($user_id) {
  global $wp_roles;
  $roles = array();
  $user = new WP_User( $user_id );
  if ( !empty( $user->roles ) && is_array( $user->roles ) ) {
  foreach ( $user->roles as $role )
    $roles[] .= translate_user_role($wp_roles->roles[$role]['name']);
  }
  return implode(', ',$roles);
}

In places where you need to hide content for ordinary users - a simple design

// Опредяляем роль
$current_user_id = get_current_user_id(); 
$current_user_role = get_user_role( $current_user_id );

// если Про
if($current_user_role == 'Pro') { 
// Выводим скрытый контент
} else {
// Выводим отлуп, например
echo 'Вам не разрешено просматривать данную страницу';
}

так же перед этим не мешает проверить залогинен ли вообще пользователь (is_user_logged_in())

It's simple and no plugins are needed. According to this principle, by the way, personal accounts are made and much more.
