如何在登录到WordPress的特定页面后重定向？

Question

我喜欢检查当前用户是否有权读取它。然后打开特殊页面。

换句话说，我想在登录到WordPress的特定页面后重定向，并限制其他用户访问它。

Answer 1

用户特定的内容是一个伟大的插件，顺利允许您通过角色或用户名指定的个人或用户组，并让他们访问特定内容。

更新： 您可以使用彼得登录重定向定义一组针对特定用户，用户与特定的角色，用户具有特定的功能重定向规则，以及所有其他用户的毯子规则。另外，请为注册后设置重定向网址。

重定向在第一次登录的用户在WordPress

在会员制的WordPress网站和要显示一个特殊的欢迎信息或新的用户指令的其他网站，你可以实现一些自定义登录重定向功能。该功能只会为每个用户启动一次（或前几次登录）。

这些功能的代码端的重要元素是使用内置的WordPress“login_redirect”过滤器，并存储有关用户是否已获得“第一次登录”处理的信息。有几种可能的方法来存储信息，无论是在cookie中还是在用户的元信息中（存储在“wp_usermeta”表中的WordPress数据库中）。

下面是一些示例代码，您可以在主题functions.php文件或插件使用方法：

基于Cookie的解决方案

// Send new users to a special page 
function redirectOnFirstLogin($redirect_to, $requested_redirect_to, $user) 
{ 
    // URL to redirect to 
    $redirect_url = 'http://yoursite.com/firstloginpage'; 
    // How many times to redirect the user 
    $num_redirects = 1; 
    // Cookie-based solution: captures users who registered within the last n hours 
    // The reason to set it as "last n hours" is so that if a user clears their cookies or logs in with a different browser, 
    // they don't get this same redirect treatment long after they're already a registered user 
    // 172800 seconds = 48 hours 
    $message_period = 172800; 

    // If they're on the login page, don't do anything 
    if(!isset($user->user_login)) 
    { 
     return $redirect_to; 
    } 

    $key_name = 'redirect_on_first_login_' . $user->ID; 

    if(strtotime($user->user_registered) > (time() - $message_period) 
     && (!isset($_COOKIE[$key_name]) || intval($_COOKIE[$key_name]) < $num_redirects) 
    ) 
    { 
     if(isset($_COOKIE[$key_name])) 
     { 
      $num_redirects = intval($_COOKIE[$key_name]) + 1; 
     } 
     setcookie($key_name, $num_redirects, time() + $message_period, COOKIEPATH, COOKIE_DOMAIN); 
     return $redirect_url; 
    } 
    else 
    { 
     return $redirect_to; 
    } 
} 

add_filter('login_redirect', 'redirectOnFirstLogin', 10, 3);

基于用户元表的解决方案

// Send new users to a special page 
function redirectOnFirstLogin($redirect_to, $requested_redirect_to, $user) 
{ 
    // URL to redirect to 
    $redirect_url = 'http://yoursite.com/firstloginpage'; 
    // How many times to redirect the user 
    $num_redirects = 1; 
    // If implementing this on an existing site, this is here so that existing users don't suddenly get the "first login" treatment 
    // On a new site, you might remove this setting and the associated check 
    // Alternative approach: run a script to assign the "already redirected" property to all existing users 
    // Alternative approach: use a date-based check so that all registered users before a certain date are ignored 
    // 172800 seconds = 48 hours 
    $message_period = 172800; 

    // If they're on the login page, don't do anything 
    if(!isset($user->user_login)) 
    { 
     return $redirect_to; 
    } 

    $key_name = 'redirect_on_first_login'; 
    // Third parameter ensures that the result is a string 
    $current_redirect_value = get_user_meta($user->ID, $key_name, true); 
    if(strtotime($user->user_registered) > (time() - $message_period) 
     && ('' == $current_redirect_value || intval($current_redirect_value) < $num_redirects) 
    ) 
    { 
     if('' != $current_redirect_value) 
     { 
      $num_redirects = intval($current_redirect_value) + 1; 
     } 
     update_user_meta($user->ID, $key_name, $num_redirects); 
     return $redirect_url; 
    } 
    else 
    { 
     return $redirect_to; 
    } 
} 

add_filter('login_redirect', 'redirectOnFirstLogin', 10, 3);
