symfony - Preparing options for updating hierarchical categories using the Doctrine extension Tree -

i'm using doctrine extension tree managing categories in hierarchical way in symfony project.

still, haven't found out how manage add/edit part in twig : can display html tree structure childrenhierarchy() method, go further , have :

root - cat 1  (+) -- cat 1-1  (+) -- cat 1-2  (+) - cat 2  (+) 

the (+) open modal displaying (category) textfield, allowing branch element on selected parent.

i haven't seen in doc, (and don't if it's possible) use method childrenhierarchy() options allowing html, ajax call.

my entity basic :

<?php namespace cpasimusante\simupollbundle\entity;  use doctrine\orm\mapping orm; use doctrine\common\collections\arraycollection; use claroline\corebundle\entity\user; use gedmo\mapping\annotation gedmo;  /**  * simupoll categories  *  * @orm\entity(repositoryclass="gedmo\tree\entity\repository\nestedtreerepository")  * @orm\table(  *      name="cpasimusante__simupoll_category",  *      uniqueconstraints={  *          @orm\uniqueconstraint(name="category_unique_name_and_user", columns={"user_id", "name"})  *      }  * )  * @doctrineassert\uniqueentity({"name", "user"})  * @gedmo\tree(type="nested")  */ class category {     /**      * @orm\id      * @orm\column(type="integer")      * @orm\generatedvalue(strategy="auto")      */     protected $id;      /**      * name of category      * @var string $value      *      * @orm\column(name="name", type="string", length=255, nullable=false)      */     private $name;      /**      * @gedmo\treeleft      * @orm\column(name="lft", type="integer")      */     private $lft;      /**      * @gedmo\treelevel      * @orm\column(name="lvl", type="integer")      */     private $lvl;      /**      * @gedmo\treeright      * @orm\column(name="rgt", type="integer")      */     private $rgt;      /**      * @gedmo\treeroot      * @orm\column(name="root", type="integer", nullable=true)      */     private $root;      /**      * @gedmo\treeparent      * @orm\manytoone(      *     targetentity="cpasimusante\simupollbundle\entity\category",      *     inversedby="children"      * )      * @orm\joincolumn(name="parent_id", referencedcolumnname="id", ondelete="cascade")      */     protected $parent;      /**      * @orm\manytoone(targetentity="claroline\corebundle\entity\user")      */     private $user;      /**      * @orm\onetomany(      *     targetentity="cpasimusante\simupollbundle\entity\category",      *     mappedby="parent",      * )      * @orm\orderby({"lft" = "asc"})      */     protected $children;      /**      * propoerty used in hierarchy display, selectbox      */     private $indentedname;      public function __construct()     {         $this->children = new arraycollection();     }      /**      * returns resource id.      *      * @return integer      */     public function getid()     {         return $this->id;     }      /**      * sets resource id.      * required resourcecontroller when creates fictionnal root      *      * @param integer $id      */     public function setid($id)     {         $this->id = $id;     }      public function getname()     {         return $this->name;     }      public function setname($name)     {         $this->name = $name;     }      /**      * returns children resource instances.      *      * @return \doctrine\common\arraycollection|category[]      */     public function getchildren()     {         return $this->children;     }      /**      * returns parent category.      *      * @return \cpasimusante\simupollbundle\entity\category      */     public function getparent()     {         return $this->parent;     }      /**      * sets parent category.      *      * @param \cpasimusante\simupollbundle\entity\category $parent      */     public function setparent(\cpasimusante\simupollbundle\entity\category $parent = null)     {         $this->parent = $parent;     }      /**      * return lvl value of resource in tree.      *      * @return integer      */     public function getlvl()     {         return $this->lvl;     }      public function getuser()     {         return $this->user;     }      public function setuser(user $user)     {         $this->user = $user;     }      /**      * allows hierachy display      * @return string      */     public function __tostring()     {         return $this->getname();     }      /**      * allows hierachy display      * @return string      */     public function getindentedname()     {         return str_repeat("--", $this->lvl) . $this->name;         //return str_repeat($this->getparent()." > ", $this->lvl) . $this->name;     } } 

my controller is, moment basic too, think potentially tweak options :

    public function indexaction(simupoll $simupoll)     {         $em = $this->getdoctrine()->getmanager();         $user = $this->container             ->get('security.token_storage')             ->gettoken()->getuser();         $repo = $em->getrepository('cpasimusantesimupollbundle:category');         $options = array(             'decorate' => true,             'rootopen' => '<ul>',             'rootclose' => '</ul>',             'childopen' => '<li>',             'childclose' => '</li>'         );         $htmltree = $repo->childrenhierarchy(             null, /* starting root nodes */             false, /* true: load children, false: direct */             $options         );         return array(             '_resource' => $simupoll,             'tree' => $htmltree,         );     } 

the template :

{% block section_content %}     <div class="panel panel-default">         <div class="panel-body" id="text_content">             {{ tree |raw }}         </div>     </div> {% endblock %} 

thank in advance if has suggestion or lead.

in fact, nodedecorator option allowed customize output :

$options = array(     'decorate' => true,     'rootopen' => '<ul>',     'rootclose' => '</ul>',     'childopen' => '<li>',     'childclose' => '</li>',     'nodedecorator' => function($node) {         return $node['name']. '<a href="#" data-id="'.$node['id'].'" class="btn btn-primary category-add-btn">+</a>';     } ); 

and use js in twig template display modal.

$('#treecontainer').on('click', '.category-add-btn', function(){     //logic display modal , pass parameter });
