- NestedSet(MPTT - Modified Preorder Tree Traversal)
- Works only with mysql and postgresql
- Optional Stefano DB This repository is 100% compatible with Zend Framework 2 DB package
- Optional Doctrine DBAL
- Add following line to your composer.json file
"stefano/stefano-tree": "*" - Add following line to your composer.json file
"doctrine/dbal": "2.*"if you want to use this library with Doctrine DBAL - Add following line to your composer.json file
"stefano/stefano-db": "~1.4.0"if you want to use this library with Stefano DB - Create db scheme example db scheme
- Create tree adapter
Use static factory method
$options = new \StefanoTree\NestedSet\Options(array(
'tableName' => 'tree_traversal', //required
'idColumnName' => 'tree_traversal_id', //required
'leftColumnName' => 'lft', //optional (default lft)
'rightColumnName' => 'rgt', //optional (default rgt)
'levelColumnName' => 'level', //optional (default level)
'parentIdColumnName' => 'parent_id', //optional (default parent_id)
));
//Stefano Db
$dbAdapter = new \StefanoDb\Adapter\Adapter(...);
//Doctrine DBAL
$dbAdapter = new \Doctrine\DBAL\Connection(...);
$tree = \StefanoTree\NestedSet::factory($options, $dbAdapter);
or create tree adapter directly
$options = new \StefanoTree\NestedSet\Options(array(...);
$dbAdapter = new \StefanoDb\Adapter\Adapter(array(...));
$nestedSetAdapter = new \StefanoTree\NestedSet\Adapter\Zend2DbAdapter($options, $dbAdapter);
$tree = new \StefanoTree\NestedSet($nestedSetAdapter);
You can join table.
$defaultDbSelect = $nestedSetAdapter->getDefaultDbSelect();
//zend framework select object
//http://framework.zend.com/manual/2.2/en/modules/zend.db.sql.html#join
$defaultDbSelect->join($name, $on, $columns, $type);
$nestedSetAdapter->setDefaultDbSelect($defaultDbSelect);
- Create new node
$targetNodeId = 10;
$data = array(
//data
);
$tree->addNodePlacementBottom($targetNodeId, $data);
$tree->addNodePlacementTop($targetNodeId, $data);
$tree->addNodePlacementChildBottom($targetNodeId, $data);
$tree->addNodePlacementTop($targetNodeId, $data);
- Update node
$targetNodeId = 10;
$data = array(
//data
);
$tree->updateNode($targetNodeId, $data);
- Move node
$sourceNodeId = 15;
$targetNodeId = 10;
$tree->moveNodePlacementBottom($sourceNodeId, $targetNodeId);
$tree->moveNodePlacementTop($sourceNodeId, $targetNodeId);
$tree->moveNodePlacementChildBottom($sourceNodeId, $targetNodeId);
$tree->moveNodePlacementChildTop($sourceNodeId, $targetNodeId);
- Delete node or branch
$nodeId = 15;
$tree->deleteBranch($nodeId);
- Clear all nodes except root node
$tree->clear();
- Get all children
$nodeId = 15;
$tree->getChildren($nodeId);
- Get all descedants
$nodeId = 15;
//all descedants
$tree->getDescendants($nodeId);
//exclude node $nodeId from result
$tree->getDescendants($nodeId, 1);
//exclude first two levels from result
$tree->getDescendants($nodeId, 2);
//get four levels
$tree->getDescendants($nodeId, 0, 4);
- Exclude branche from result
$nodeId = 15;
$excludeBranche = 22;
$tree->getDescendants($nodeId, 0, null, $excludeBranche);
- Get Path
$nodeId = 15;
//full path
$tree->getPath($nodeId);
//exclude node $nodeId from result
$tree->getPath($nodeId, 1);
//exclude first two levels from result
$tree->getPath($nodeId, 2);
//exclude last node
$tree->getPath($nodeId, 0, true);
- rebuild tree
