    <{/if}>
</nav>

{* Usage *}
<{include file="db:mymodule_pagination.tpl" page=$current_page total_pages=$pages base_url=$url}>

Kinerja

Menyimpan dalam cache

// In PHP
$xoopsTpl->caching = 1;
$xoopsTpl->cache_lifetime = 3600; // 1 hour

// Check if cached
if (!$xoopsTpl->is_cached('mymodule_index.tpl')) {
    // Fetch data only if not cached
    $items = $handler->getObjects();
    $xoopsTpl->assign('items', $items);
}

Hapus Tembolok

// Clear specific template
$xoopsTpl->clear_cache('mymodule_index.tpl');

// Clear all module templates
$xoopsTpl->clear_all_cache();

Praktik Terbaik

1. Escape Output - Selalu keluar dari konten buatan pengguna
2. Gunakan Pengubah - Terapkan transformasi yang sesuai
3. Jaga Logika Minimal - Logika kompleks termasuk dalam PHP
4. Gunakan Sebagian - Gunakan kembali fragmen template umum
5. Semantik HTML - Gunakan elemen HTML5 yang tepat
6. Aksesibilitas - Sertakan atribut ARIA jika diperlukan
