Baumstruktur kopieren (MySQL/PHP)

[Volker Z.]

Hallo,

du könntest es mal so versuchen (die Methoden childList und copyNode wie gehabt):

Code:

  private function setParentId(&$nodes, $value){
    foreach($nodes as &$node)
      $node['parent_id'] = $value;
  }

  public function copyTree($nodes){
    if(is_array($nodes)){
      foreach($nodes as $node){
        $children = $this->childList($node['item_id']);
        if(is_array($children) == false)
          $this->copyNode($node);
        else{
          $this->setParentId($children, $this->copyNode($node));
          $this->copyTree($children);
        }
      }
    }
  }

Der Aufruf dann mit:

Code:

$this->copyTree($this->childList(0));

Gruß
