如果否则 WP is_user_logged_in 没有显示正确的内容

Question

I just write following code

if ( is_user_logged_in() ) 
{
    $filter = array(
        'post_status' => 'private',
    );
} 
else 
{
    $filter = array(
        'post_status' => 'publish',
    );
}

I have header with token so should it work. But always appears 'publish' posts

What I'm doing wrong?

Welcome to Stack Overflow! It looks like you've got a few issues. First and foremost, make sure your code is properly formatted with indents/spaces. It gets very hard to read very quickly without having a consistent formatting structure:

With that said, it seems like you've got a ways to go on understanding the fundamentals of WordPress programming, and/or you're not including all of the code. For instance, what does $filter reference, when/where is this code being run? You're either missing the surrounding code in your example, or you just put this code somewhere and there's nothing for it to reference and modify.

WordPress makes use of a Template Hierarchy and is extensible via Filter Hooks and Action Hooks . You'll need at least a general understanding of those, as well as "The Loop" , in order to really get WordPress to do what you want.

Based on the snippet you've provided, it looks like you want to display only private posts to users that are logged in, I'm assuming in your main query. You can make use of the pre_get_posts hook to modify a WP Loop query. Something like this should get you started:

add_action( 'pre_get_posts', 'modify_query_if_logged_in' );
function modify_query_if_logged_in( $query ){
    // Abort if we're in /wp-admin or this isn't the main query
    if( ! is_admin() && $query->is_main_query() ){
        // If user is logged in
        if( is_user_logged_in() ){
            // Only show private posts
            $query->set( 'post_status', 'private' );
        }
    }
}

Just drop that in your functions.php file and it should work. You can also add in any other conditions you want, like is_front_page() to only have it run on the home page (which sort of makes ! is_admin() redundant and unnecessary), or adjust the $query to show both regular and private posts with $query->set( 'post_status', array('private', 'publish') );
