Getting posts from multiple users?

Question

Using a third party plugin that allows users to follow each other, we can retrieve the users being followed like so (commented):-

<?php if (have_posts()) : ?>
        <?php global $userpro_social;

        $following = $userpro_social->following( get_current_user_id() ); //get users the current user is following
        print_r($following) ?> // print the array so we can see who we're following


        <?php $paged = get_query_var( 'paged' ) ? get_query_var( 'paged' ) : 1; ?>     
        <?php query_posts( array( 'author'=> ??? , 'paged' => $paged, ) ); ?>      

        <?php while ( have_posts() ) : the_post() ?>


            <?php if ( has_post_format( 'video' )) {
                    get_template_part( 'video-post' );
                }elseif ( has_post_format( 'image' )) {
                    get_template_part( 'image-post' );
                } else {
                   get_template_part( 'standard-post' );
                }

            ?>

        <?php endwhile;?>

        <?php endif; ?>

So this would output something like this

Array ( [24] => 1 [1] => 1 )

ie, we're following users with the ID of 1 and 24, simple enough?

The part I'm lost on is this

<?php query_posts( array( 'author'=> ??? , 'paged' => $paged, ) ); ?>   

How do I actually output posts from those users, it's already stored in the array so I think it should be easy enough, but I just can't figure it out even after reading the codex.

Answer 1

First of all, I suggest don't use query_posts. (No one is really a WPSE user if had no read this answer).

So you can use WP_Query with author__in parameter in combination with array_keys PHP function.

$paged = get_query_var( 'paged' ) ? get_query_var( 'paged' ) : 1;    

$query = new WP_Query(
  array( 'author__in' => array_keys( $following ), 'paged' => $paged )
);

while ( $query->have_posts() ) : $query->the_post();
  // your loop here
endwhile;

wp_reset_postdata();

PS: you don't need to open and close php tags on every line.
