Multiple Post Types & Organized JSON Structure

Search Multiple Post Types Sekaligus

post_type sebagai Array:

$mainQuery = new WP_Query(array(
  'post_type' => array('post', 'page', 'professor', 'program', 'event', 'campus'),
  's'         => sanitize_text_field($data['term'])
));

Aktifkan REST API untuk Custom Post Types

Tambahkan 'show_in_rest' => true di registrasi CPT (mu-plugins/university-post-types.php):

register_post_type('professor', array(
  // ... setting lainnya
  'show_in_rest' => true
));

Organisasi: Sub-Arrays per Post Type

Daripada semua results tercampur, buat sub-arrays terpisah:

function university_search_results($data) {
  $mainQuery = new WP_Query(array(
    'post_type' => array('post', 'page', 'professor', 'program', 'event', 'campus'),
    's'         => sanitize_text_field($data['term'])
  ));

  $results = array(
    'generalInfo' => array(),
    'professors'  => array(),
    'programs'    => array(),
    'events'      => array(),
    'campuses'    => array()
  );

  while ($mainQuery->have_posts()) {
    $mainQuery->the_post();

    if (get_post_type() == 'post' OR get_post_type() == 'page') {
      array_push($results['generalInfo'], array(
        'title'      => get_the_title(),
        'permalink'  => get_the_permalink(),
        'postType'   => get_post_type(),
        'authorName' => get_the_author()
      ));
    }

    if (get_post_type() == 'professor') {
      array_push($results['professors'], array(
        'title'     => get_the_title(),
        'permalink' => get_the_permalink(),
        'image'     => get_the_post_thumbnail_url(0, 'professorLandscape')
      ));
    }

    if (get_post_type() == 'program') {
      array_push($results['programs'], array(
        'title'     => get_the_title(),
        'permalink' => get_the_permalink(),
        'id'        => get_the_ID()
      ));
    }

    if (get_post_type() == 'event') {
      $eventDate = new DateTime(get_field('event_date'));
      $description = null;
      if (has_excerpt()) {
        $description = get_the_excerpt();
      } else {
        $description = wp_trim_words(get_the_content(), 18);
      }
      
      array_push($results['events'], array(
        'title'       => get_the_title(),
        'permalink'   => get_the_permalink(),
        'month'       => $eventDate->format('M'),
        'day'         => $eventDate->format('d'),
        'description' => $description
      ));
    }

    if (get_post_type() == 'campus') {
      array_push($results['campuses'], array(
        'title'     => get_the_title(),
        'permalink' => get_the_permalink()
      ));
    }
  }

  return $results;
}

Struktur JSON Hasil:

{
  "generalInfo": [
    { "title": "About Us", "permalink": "...", "postType": "page", "authorName": "Brad" }
  ],
  "professors": [
    { "title": "Dr. Barks A Lot", "permalink": "...", "image": "...jpg" }
  ],
  "programs": [
    { "title": "Biology", "permalink": "...", "id": 97 }
  ],
  "events": [
    { "title": "Science of Cats", "permalink": "...", "month": "Jan", "day": "15", "description": "..." }
  ],
  "campuses": []
}

Keuntungan Struktur Ini:

• Data sudah terorganisir per post type
• Front-end JavaScript mudah mengakses: results.generalInfo, results.professors, dll.
• Siap untuk 3-column layout di search overlay
• Setiap post type bisa punya property berbeda sesuai kebutuhan display
