WP_User_Query and user posts

by

If you pass in the fields parameter to your user query you can easily get an array of ids to the pass in to your wp query :

//WP User Query
$author_query = new WP_User_Query( array (
    'number' => 3,
    'fields' => 'ID'
));

$author_results = $author_query->results;   

//WP Query
$postArgs = array (
    'author__in'=> $author_results,
    'post_type' => 'post',
    'posts_per_page' => 5,
);
