php - List all blogs, but exclude the main site

文章数量:1327962

I am using this function that gives me a shortcode I can paste anywhere on the site. It lists all blogs in the multisite network a user has, but I would like to hide the main site from the list. Can someone help to adjust the snippet?

-Extra question. - is it possible to show blogs website preview like Facebook?

function show_blog_list() {
 
    $user_id = get_current_user_id();
    if ($user_id == 0) {
        echo 'You are not logged in.';
    } else {
        echo '<h2>Here is your blog list</h2>';
        $user_blogs = get_blogs_of_user( $user_id );
        foreach ($user_blogs AS $user_blog) {
            echo '<li><a href="'.$user_blog->siteurl.'">'.$user_blog->blogname.'</a></li>';
        }
        echo '</ul>';
    }
 
}
add_shortcode( 'bloglist', 'show_blog_list' );

I've never used it, but it looks like get_main_site_id is what you want to figure that out, so therefore your code might look like:

$mainSiteId = get_main_site_id();
foreach ($user_blogs AS $user_blog) {
    if ($userblog->site_id != $mainSiteId) {
        echo '<li><a href="'.$user_blog->siteurl.'">'.$user_blog->blogname.'</a></li>';
    }
}
