将登录的Wordpress用户重定向到登录屏幕之外，并根据其自定义元数据返回特定的URL

Question

I currently have a solution which: a) requires login before you can access the site b) redirects to login page (note this is also the home page/front page) if the person attempts to hit any page in the site but is not logged in c) directs the user on successful login to a site specific url most suitable to them based on some custom meta data in their profile

However I want to set up a further redirect should a user who is already logged-in hit the login page again and effectively achieve exactly the same re-directions as in C above.

I've attempted to utilise existing add_login_check code which uses is_user_logged_in and wp_redirect ... but I can't seem to attach additional if and elseif statements. So something like this works great for a single redirect but I need to enhance it to cope with more conditions

add_action('wp', 'add_login_check');

function add_login_check()
{
if ( is_user_logged_in() && is_page(86) ) {
    wp_redirect('/desired_url');
    exit;
}
}
add_action('wp', 'add_login_check');

So I attempted to modify to:

function add_login_check()
{
if ( is_user_logged_in() && is_page(86) && 'CustomResponse1' == 
get_user_meta( $user->ID, 'Custom_Group1', true ) && 'CustomResponse2' == 
get_user_meta( $user->ID, 'CustomGroup2', true )) {
    wp_redirect('/desired_url');
    exit;
}
}
add_action('wp', 'add_login_check');

I've added && 'CustomResponse1' == get_user_meta( $user->ID, 'Custom_Group1', true ) && 'CustomResponse2' == get_user_meta( $user->ID, 'CustomGroup2', true ) to that standard code, but when a logged-in user returns to the login page they just stay there and it does not redirect.

Any help on this would be greatly appreciated. In the above my users have two additional fields (I've referred to CustomGroups 1 & 2). And then there are selections which can be made in those fields (I've referred to CustomResponses 1 & 2) - based on these alongside the request page and current status being logged in I want them to be redirected.

I want to build in some additonal elseif statements so the redirects are dependent on different customresponses.

Any help greatly appreciated.

You are trying to use a undefined variable $user . Use wp_get_current_user() function to retrieve the current user object.

function add_login_check()
{
    if ( is_user_logged_in() )
    { 
        $user = wp_get_current_user();
        if ( is_page(86) && 
             'CustomResponse1' == get_user_meta( $user->ID, 'Custom_Group1', true ) && 
             'CustomResponse2' == get_user_meta( $user->ID, 'CustomGroup2', true )) 
        {
            wp_redirect('/desired_url');
            exit;
        }
    }
}

This was the solution used in the end

function redirect_my_page()
{
global $current_user;
$user = wp_get_current_user();
if ( is_user_logged_in() && is_page(86) && 'CustomResponse1' == get_user_meta( $user- 
>ID, 'CustomGroup1', true ) && 'CustomResponse2' == get_user_meta( $user->ID, 
'CustomGroup2', true ))
{
wp_redirect('http://desiredurl/');
exit;
}
elseif ( is_user_logged_in() && is_page(86) && 'CustomResponse1a' == get_user_meta( 
$user->ID, 'CustomResponse1', true ) && 'CustomResponse2a' == get_user_meta( $user- 
>ID, 'CustomResponse2', true ))
{
wp_redirect('http://desiredurl/');
exit;
}
}
add_action('template_redirect', 'redirect_my_page');
