Sulu Symfony CMS  :  play with child's of node

Sulu give you  the ability to create page content (node of type content) , and this page can contain child's page as you know CMS system need this technique for more flexibility .

First you can get the instance of your parent document let's say you have blog as the top parent document of other child's , ok for getting the path of you document you can extract from table phpcr_nodes in your db from column path ok my path is '/cmf/ibnab/contents/blog' (sulu take the name of this path document from title of your page content)

Ok now getting the service document_manager and find your document :

 
$documentManager = $this->get('sulu_documentmanager.document_manager');
$document = $documentManager->find('/cmf/ibnab/contents/'.$toptag ,$languageCode);
 

And now get service node_repository and use for getting the childs document (or nodes) :

 
$webspaceKey = 'ibnab';
$languageCode = 'en';
$repository = $this->get('sulu_content.node_repository');
$_currentblog = $repository->getNodes(
$document->getUuid(),
$webspaceKey,
$languageCode
);
 

Yes pass to twig :

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

And inside twig :

 
 {% if page._embedded.nodes is defined %}
{% for child in page._embedded.nodes %}
 <li class="2">
<a href="{{ sulu_content_path((child .url)) }}">{{ child.title }}</a></li>
{% endfor %}
{% endif %}
 

Ok that is all .
