How to get current site id? (WPMU)

Question

I am using WordPress with MU activated. I found a function here that supposed to return an object with the current side ID. But it's returning 1 for all websites.

<?php get_current_site(); ?>

Answer 1

You're right, get_current_site()->blog_id will return 1, as it refers to the network.

To get the current site (blog) ID you can go like this:

<?php echo get_current_blog_id(); ?>

Moreover you can get the current site (blog) details like this:

<?php var_dump(get_blog_details()->blog_id); ?>

Answer 2

First of all check whether user belong from current site by using

 <?php is_user_member_of_blog( $user_id, $blog_id ); ?>

After you get id of user create user role

$user = new WP_User( $user_id );
if ( $user ) {
$roles = $user->roles; 

and in last create posts for every user by adding role in args. not tested but i'll do trick for you.

<?php
$args1 = array(
    'role' => 'subscriber',
    'orderby' => 'user_nicename',
    'order' => 'ASC'
);
$subscribers = get_users($args1);
echo '<ul>';
foreach ($subscribers as $user) {
    echo '<li>' . $user->display_name.'['.$user->user_email . ']</li>';
}
echo '</ul>';

?>
