01

Pattern.

Theme-as-installer

The theme is the installer. Activate it = full site, production-ready, without a single click in wp-admin.

  1. 01

    Self-bootstrapping pages

    When the theme activates, bernad_create_*_page() runs on the after_setup_theme hook. Each function checks whether the page already exists (get_page_by_path); if not, it creates it with wp_insert_post and assigns the template via the _wp_page_template meta. Zero manual steps — install the theme and the site is complete.

  2. 02

    Service-specific templates

    12 dedicated templates, one per medical specialty: page-implantologia.php, page-endodoncia.php, page-ortodoncia.php, page-cirugia-oral.php, etc. Each with its own copy, hero, FAQs and schema. Maintainable through clear separation of concerns.

  3. 03

    Institutional pages module

    4 extra templates for "facilities", "technology", "team", "about" — same auto-creation cycle with their assigned templates. Information architecture codified in the theme, not in wp-admin.

  4. 04

    DRY page-creation helper

    Reusable function bernad_create_page_if_not_exists($slug, $title, $template) abstracts the pattern. Service and info functions iterate over config arrays and delegate to the helper. Adding a new specialty = one line in the array.

  5. 05

    Permalinks auto-flush

    When pages are created/assigned, a deferred flush_rewrite_rules is scheduled to guarantee clean URLs (/implantologia/, /endodoncia/) without requiring the admin to touch Settings → Permalinks.

The bootstrapping pattern

functions.php · service pages bootstrap 

function bernad_create_page_if_not_exists(
    $slug, $title, $template_name
) {
    if (get_page_by_path($slug)) return;

    $page_id = wp_insert_post([
        'post_title'   => $title,
        'post_name'    => $slug,
        'post_status'  => 'publish',
        'post_type'    => 'page',
    ]);

    if ($page_id && $template_name) {
        update_post_meta(
            $page_id, '_wp_page_template', $template_name
        );
    }
}

function bernad_create_service_pages() {
    $services = [
        'implantologia'    => ['Implantología',    'page-implantologia.php'],
        'endodoncia'       => ['Endodoncia',       'page-endodoncia.php'],
        'ortodoncia'       => ['Ortodoncia',       'page-ortodoncia.php'],
        // ... 9 more specialties
    ];

    foreach ($services as $slug => $data) {
        bernad_create_page_if_not_exists(
            $slug, $data[0], $data[1]
        );
    }
}
add_action('after_setup_theme', 'bernad_create_service_pages');
