CPT archive page - show one post from each taxonomy term

Question

Basic loop question:

I have a custom post type with a custom taxonomy and 3 terms.

On the archive page (archive-custom_post_type.php), I would like to display one post from each taxonomy term.

Is this possible within the standard if (have_posts()) : while (have_posts()) : the_post(); loop, or do I have to make separate loops for each one?

Answer 1

So I went ahead and did the multiple loop thing, as I had done before. I'm always interested in seemingly cleaner/simpler solutions, but sometimes you just have to keep moving. This is the code I'm using:

<?php   
    $args = array(
        'post_type'         => 'projects',
        'project_category'  => 'websites',
        'orderby'           => 'menu_order',
        'showposts'         => 1
    );

    $posts = get_posts( $args );
    foreach ($posts as $post) :  setup_postdata($post); 

?>

// Get the post stuff here

<?php endforeach; wp_reset_postdata(); ?>

I can repeat this as needed, changing the taxonomy (in this case the taxonomy is project_category) term each time.

Please feel free to comment an tell me if this isn't a good way to do it. I'm far from an expert at the PHP side of WordPress.
