php - How can I show recent blogbost from wp multisites on my mainpage -

i'm having trouble wordpress. i'm rather new wordpress , not familiar how works. said, i'm working on project in wordpress incluedes main site , couple of different sub sites. i'm using wordpress multisites.

what want show latest blogpost every sub site on mainsite.

i know how fix 1 site:

<?php $the_query = new wp_query('posts_per_page=6'); ?>   <?php while ($the_query -> have_posts()) : $the_query -> the_post(); ?>        <a href="<?php the_permalink() ?>"><div class="col-md-3 col-xs-12">        <p><i class="fa fa-user"></i> <?php the_author(); ?>       <i class="fa fa-clock-o"></i> <time><?php the_date(); ?></time></p>        <?php $email = get_the_author_meta('', $author); ?>       <?php $bild = get_avatar_url($email); ?>       <img src="<?php echo $bild; ?>" id="avatarimg">         <h3><?php the_title(); ?></h3>       </div></a>     <?php         endwhile;         wp_reset_postdata();      ?> 

the above codesnippet works single wordpress site , it's excactly how want works multiple sites.

what have managed fetch blogposts other sites using code:

<?php   $all_blog = get_sites();   foreach ($all_blog $key=>$current_blog) {     // switch each blog posts     switch_to_blog($current_blog->blog_id);       // fetch posts       $blog_posts = get_posts(array( 'posts_per_page' => 1));       restore_current_blog();         // display posts         echo $blog_posts[0]->post_content;   }  ?>  

this code gives me content recent blog posts blogs. havn't figured out how display data in first codesnippet.

i don't know how directly you.

but perhaps if take @ wpmudev autopost plugin code might find answer. used time ago thing.
