Sulu cms framework is an open-source content management platform based on the Symfony PHP framework. Use it as a CMS to develop and manage enterprise multi-sites or as a development environment to create reliable and high-performant web-apps.
The official doc is here

That is our first tutorial in this cms , we used and observe that is easy and practice but need more large community .

Ok this tutorial cover how getting collection of nodes based on tag name .

- Some parameters used inside our code :

 

 
        $dataSource = null;
        $includeSubFolders = null;
        $languageCode = 'en';
        $tagOperator = 'or';
        $sortBy = 'date';
        $sortMethod = 'asc';
        $exclude = null;
        $webspaceKey = 'ibnab';
        $limitResult = 1;
        $tagNames = 'sulu';
        $resolvedTags = [];
 

- Get service tag manager :

 
        $tagManager = $this->get('sulu_tag.tag_manager');
        if (isset($tagNames)) {
            $tags = explode(',', $tagNames);
            foreach ($tags as $tag) {
                $resolvedTag = $tagManager->findByName($tag);
                if ($resolvedTag) {
                    $resolvedTags[] = $resolvedTag->getId();
                }
            }
        }
 

- Some code about sorted columns :

 
        $sortColumns = [];
        if (isset($sortBy)) {
            $columns = explode(',', $sortBy);
            foreach ($columns as $column) {
                if ($column) {
                    $sortColumns[] = $column;
                }
            }
        }
 

- Create global  configuration used in our repository selection :

 
        $filterConfig = [
            'dataSource' => $dataSource,
            'includeSubFolders' => $includeSubFolders,
            'limitResult' => $limitResult,
            'tags' => $resolvedTags,
            'tag' => $tagOperator,
            'sortBy' => $sortColumns,
            'sortMethod' => $sortMethod,
        ];
 

- New get service and call the method  getFilteredNodes :

 
        /** @var NodeRepository $repository */
        $repository = $this->get('sulu_content.node_repository');
        $contents = $repository->getFilteredNodes(
            $filterConfig,
            $languageCode,
            $webspaceKey,
            true,
            true,
            $exclude !== null ? [$exclude] : []
        );
 

 
   
- The collections nodes is inside :

 
        $contents =  $contents['_embedded']['nodes'];
 

- You can pass to twig :

 
        $response = $this->renderStructure(
            $structure,
            ['contents' => $content],
            $preview,
            $partial
        );
        return $response;
 

- Now dumping inside twig :

 
{{ dump(contents) }}
 

that is all
