Wordpress-按用户角色限制页面-URL重定向

[英]Wordpress - Restrict page by user role - URL Redirect

我试图限制除“图书管理员”以外的所有用户角色的页面

我在example.com/library-dashboard上有一个图书馆仪表板

当不是“图书馆员”的用户角色迷路时访问此页面时,我需要将其重定向到example.com/subscription-needed

我为此使用以下功能:

function is_corr_user($page_slug) {

  // User has to be logged in
  if(!is_user_logged_in())
    return false;

  // All user roles
  $roles = wp_get_current_user()->roles;

  // For each page check if user has required role
  switch($page_slug) {
    case "library-dashboard":
     return in_array('librarian, administrator', $roles);
    default:
      return false;
  }
}


// Hook to wordpress before load and check if correct user is on page
add_action( 'wp', 'wpse69369_is_correct_user' );
function wpse69369_is_correct_user()
{
    global $post;

    // Redirect to a custom page if wrong user
    if(!is_corr_user($post->post_name)) {
      wp_redirect( '/subscription-needed/' );
      exit;
    }     
}

我的问题是,此功能现在将所有页面重定向到example.com/subscription-needed/包括主页,并且我收到太多重定向错误。

如何解决此问题,因此该功能仅适用于example.com/library-dashboard页面上给定的用户角色librarian

因此,我要实现的目标是,如果librarianadministrator访问example.com/library-dashboard则什么也不会发生,并且该页面将正常显示。

但是,如果其他不是librarianadministrator用户角色访问了example.com/library-dashboard页面,则应将其重定向到example.com/subscription-needed/

检查以下代码。

add_action('wp', 'redirectUserOnrole');
function redirectUserOnrole() {
 //First i am checking user logged in or not
 if (is_user_logged_in()) {
    $user = wp_get_current_user();
    $role = (array) $user->roles;
    //checking for the user role you need to change the role only if you wish
    if ($role[0] != 'librarian' || $role[0] != 'administrator') {
        global $post;
        if ($post->post_name == 'library-dashboard') {
            wp_redirect('/subscription-needed/');
            exit;
        }
    }
 } else {
    return true;
 }
}

这对我有用,可以用它代替is_corr_user()wpse69369_is_correct_user()函数:

add_action( 'template_redirect', 'librarian_dashboard_redirect' );
function librarian_dashboard_redirect() {
    if ( is_user_logged_in() && is_page( 'library-dashboard' ) ) {
        $user = wp_get_current_user();
        $valid_roles = [ 'administrator', 'librarian' ];

        $the_roles = array_intersect( $valid_roles, $user->roles );

        // The current user does not have any of the 'valid' roles.
        if ( empty( $the_roles ) ) {
            wp_redirect( home_url( '/subscription-needed/' ) );
            exit;
        }
    }
}
