// === information.php controller patch (OpenCart 4.x) ===
// Goal: set About Us meta + canonical; expose OG/Twitter vars to header.twig; remove duplicate H1 via template change only.

// 1) Ensure canonical uses the Document links API (header.twig already renders {{ links }})
$this->document->addLink(
    $this->url->link('information/information', 'information_id=' . (int)$information_id, true),
    'canonical'
);

// 2) (Optional) If this is the About Us page, set bespoke title & meta description
// Replace {ABOUT_ID} with your About page information_id from Admin > Design > Information
if ((int)$information_id === {ABOUT_ID}) {
    $this->document->setTitle('About Us | Popper Express Australia');
    $this->document->setDescription('Learn about Popper Express Australia — Melbourne-based since 2007. Authentic brands, fast discreet shipping, and customer-first support across Australia.');

    // 3) Pass dynamic OG/Twitter variables to header.twig (with sensible fallbacks)
    $data['og_url'] = $this->url->link('information/information', 'information_id=' . (int)$information_id, true);
    $data['og_title'] = $this->document->getTitle();
    $data['og_description'] = $this->document->getDescription();
    // Optionally choose a branded image
    $data['og_image'] = $this->config->get('config_logo') ? ($this->config->get('config_secure') ? HTTPS_SERVER : HTTP_SERVER) . 'image/catalog/share/og-home.jpg' : '';
    $data['og_image_alt'] = 'Popper Express Australia';

    $data['twitter_title'] = $data['og_title'];
    $data['twitter_description'] = $data['og_description'];
    $data['twitter_image'] = $data['og_image'];
}

// 4) Clear theme and modification caches after deploying header.twig + information.twig changes.
