Nested Set Behaviour
--------------------

[](#nested-set-behaviour)

Phalcon implementation for tree / hierarchy through nested sets implementation. It will calculate edges and depth for a category on creation, update and delete.

Moving "branches" is not supported (o sub-node with all it's sub-nodes) and won't be. This tool is meant to "react" to changes on a single record and keep the rest of the tree position in place.

prerequisites
-------------

[](#prerequisites)

Your DB must have parent, left, right, depth columns. Example:

```
CREATE TABLE `categories` (
	`id` INT(11) NOT NULL AUTO_INCREMENT,
	`name` CHAR(50) NULL DEFAULT NULL,
	`parent_id` INT(11) NULL DEFAULT NULL,
	`_left` INT(11) NULL DEFAULT NULL,
	`_right` INT(11) NULL DEFAULT NULL,
	`_depth` INT(11) NULL DEFAULT NULL,
	PRIMARY KEY (`id`)
);
```

usage
-----

[](#usage)

```
class MyModel extends \Phalcon\Mvc\Model {
    public function initialize() {
        $this->addBehaviour(new \P4BGroup\NestedSets\Behaviour());
    }
}
```

usage

this behaviour will automatically calculate the edges and depth of each node on save / delete
