A PHP library to load the Branding and Orbit Webservices and cache them for a short period. These two webservices are used together to provide a content skeleton for BBC pages hosed outside of the Forge platform.

Eventually Orbit content may be included within the Branding Webservice's output, but we have not yet considered the benefits and trade-offs of that just yet.

Add this repository to your composer.json, and add bbc/branding-client as a dependency.

{
    "repositories": [
        {
            "type": "vcs",
            "url": "[email protected]:bbc/branding-client.git"
        }
    ],
    "require": {
        "bbc/branding-client": "^2.0"
    }
}

Branding shall return branding information, some of which should be then passed to the call to the Orbit webservice along with blocks of HTML that should be injected into your page layout.

Create a BrandingClient, passing in an instance of GuzzleHttp\Client, an implementation of Psr\Cache\CacheItemPoolInterface, and optionally an options array. Then call getContent() to make a request and return a Branding domain model.

After that make a call to the OrbitClient, passing in the Variant and Language options from the branding information.

The first argument of BrandingClient->getContent() is the published BrandingId you want to render. The second argument of BrandingClient->getContent() is the preview ThemeVersionId that should be shown. Consumers SHOULD implement this if they want to support previewing not-yet-published themes.

$httpClient = new \GuzzleHttp\Client();
$cache = new \Symfony\Component\Cache\Adapter\ArrayAdapter();
$brandingOptions = [];
$orbitOptions = [];
$projectId = 'br-0001';
$themeVersionId = null;
// If you want to support the preview query strings suggested by the Branding
// Tool, set the themeVersionId to the following (ideally using your
// framework's prefered mechanism for reading query parameters):
// $themeVersionId = $_GET[\BBC\BrandingClient\BrandingClient::PREVIEW_PARAM];

$brandingClient = new \BBC\BrandingClient\BrandingClient(
    $httpClient,
    $cache,
    $brandingOptions // optional
);

$branding = $brandingClient->getContent($projectId, $themeVersionId);

$orbitClient = new \BBC\BrandingClient\OrbitClient(
    $httpClient,
    $cache
    $orbitOptions // optional
);

$orb = $orbitClient->getContent([
    'variant' => $branding->getOrbitVariant(),
    'language' => $branding->getLanguage(),
], [
    'searchScope' => $branding->getOrbitSearchScope(),
    // Any additional template replacements you need to pass to Orbit
    // See https://navigation.api.bbc.co.uk/docs/index.md for the various
    // template keys available
]);

Valid $options keys to pass to the BrandingClient are:

• env: To set an environment to request Branding from. Must be one of 'live', 'test' or 'int'. If omitted, shall default to 'live'.
• cacheKeyPrefix: A prefix to use for the cache key. If omitted, shall default to 'branding'.
• cacheTime: By default the Client uses the cache control headers of the API response determine how long to cache for. To override this value set the cacheTime to a value in seconds.

Valid $options keys to pass to the OrbitClient are:

• env: To set an environment to request Orbit from. Must be one of 'live', 'test' or 'int'. If omitted, shall default to 'live'.
• cacheKeyPrefix: A prefix to use for the cache key. If omitted, shall default to 'orbit'.
• cacheTime: By default the Client uses the cache control headers of the API response determine how long to cache for. To override this value set the cacheTime to a value in seconds.
• mustache: An array of options to pass to the Mustache_Engine such as cache. Check the Mustache Wiki for available options.
• useCloudIdcta: boolean, false by default, indicating whether requests to navigation..bbc.co.uk should include X-Feature header, accommodating cloud idcta

The Branding object returned from BrandingClient->getContent() is a domain object that contains information you should pass to the Orbit client and blocks of content that you should render in your page.

• $branding->getHead() should be injected into your <head>, directly after Orbit's head content.
• $branding->getBodyFirst() should be injected at the top of the <body>, directly after Orbit's bodyFirst content.
• $branding->getBodyLast() should be injected at the bottom of the <body>, directly before Orbit's bodyLast content.
• $branding->getOrbitThemeClasses() should be added to your <html> element's class attribute to give the Orb the correct coloring.

The Orbit object returned from OrbitClient->getContent() is a domain object that contains information you should pass to the Orbit client and blocks of content that you should render in your page.

• $orbit->getHead() should be injected into your <head>
• $orbit->getBodyFirst() should be injected at the top of the <body>
• $orbit->getBodyLast() should be injected at the bottom of the <body>
