Pagination Fix

FacetWP sometimes conflicts with Blocksy, causing the posts_per_page from the customizer to not be used. This snippet should fix that issue.

/**
 * Set posts_per_page for FacetWP pagination
 */
function set_facetwp_pagination(\WP_Query $query)
{
  // Only modify the main query on the frontend
  if (is_admin() || !$query->is_main_query()) {
    return;
  }

  // Only proceed for post type archive pages, blog page, or category archives
  if (!$query->is_post_type_archive() && !$query->is_home() && !$query->is_category()) {
    return;
  }

  // Get the post type from the query
  $post_type = $query->get('post_type');

  // Handle different archive types with Blocksy's naming convention
  if ($query->is_home()) {
    // Blog home page
    $theme_mod_key = 'blog_archive_per_page';
  } elseif ($query->is_category()) {
    // Category archive
    $theme_mod_key = 'categories_archive_per_page';
  } else {
    // Post type archives
    if (is_array($post_type)) {
      $post_type = reset($post_type);
    }
    $theme_mod_key = "{$post_type}_archive_archive_per_page";
  }

  // Get the per-page value from theme mod, fallback to site default if not set
  $per_page = get_theme_mod($theme_mod_key, get_option('posts_per_page', 10));

  // Set the posts_per_page for this query
  $query->set('posts_per_page', $per_page);
}
add_action('pre_get_posts', 'set_facetwp_pagination');
