PM Scrum story

 

«As an eZ Publish user, I don’t want to be
pissed off by a new #@!$% version!»

The challenges

  • 100% data compatible (same database schema)
  • Include legacy templates into new ones
  • Routing fallback
  • Load legacy content templates with old override rules
  • Settings
  • Access Symfony services from legacy PHP code (e.g. modules)

Dual Core architecture

Dual core architecture

Concrete example: Using eZ Find


$searchPhrase = 'My search phrase';
$sort = array(
    'score'     => 'desc',
    'published' => 'desc'
);
$contentTypeIdentifiers = array( 'folder', 'article' );
$mySearchResults = $this->getLegacyKernel()->runCallback(
    function () use ( $searchPhrase, $sort, $contentTypeIdentifiers )
    {
        // eZFunctionHandler::execute is the equivalent for a legacy template fetch function
        // The following is the same than fetch( 'ezfind', 'search', hash(...) )
        return \eZFunctionHandler::execute(
            'ezfind',
            'search',
            array(
                'query'     => $searchPhrase,
                'sort_by'   => $sort,
                'class_id'  => $contentTypeIdentifiers
            )
        );
    },
    false
);

Call Symfony services from legacy code


// From anywhere in legacy code
/** @var \Symfony\Component\DependencyInjection\ContainerInterface $serviceContainer */
$serviceContainer = ezpKernel::instance()->getServiceContainer();
$repository = $serviceContainer->get( 'ezpublish.api.repository' );
$rootLocation = $repository->getLocationService()->loadLocation( 2 );
  • You can call and use every declared public service
  • As controllers can be defined as services, you can use controllers for your modules!
    (particularly useful for module migration)

If I migrate to eZ 5, will my site work?

  • Short answer: YES!!!
    • Define new Twig templates, they will used directly
    • If no Twig template yet, all your old content templates
      will be taken into account as fallback
    • All your modules will continue to work (routing fallback)
