Question

How can I list posts as sub-items of authors? It should look like:

<ul>
    <li>Author</li>
        <ul>
            <li>Post1</li>
            <li>Post2</li>
        </ul>
    </li>
</ul>

I have an array containing author data including $author->ID. This comes from get_users().
My function looks like this:

function add_custom_menu_items($items, $args) {

    $authors = get_users('role=author'); \\Returns array of author meta-data.

    return $items.$authors_str;    
}
add_filter( 'wp_nav_menu_items', 'add_custom_menu_items', 5, 2);

Where can I get a list of posts?

Answer 1

User wp query to query posts for each author:

$the_query = new WP_Query( 'author=123' );

or

$the_query = new WP_Query( 'author_name=rami' );

and loop through each post like:

// The Loop
while ( $the_query->have_posts() ) : $the_query->the_post();
    echo '<li>';
    the_title();
    echo '</li>';
endwhile;

// Reset Post Data
wp_reset_postdata();
