kohana-tree

Kohana array-to-tree module

This module was created to build tree structures from flat arrays.
In simple language: build menus, catalogues, folder-structures etc with your data from database.

Installation

1. place 'tree' folder in your kohana modules directory
   
2. add module in your bootstrap file (like this: 'tree'=>MODPATH.'tree', )
   
3. enjoy!
   

Usage

First of all get data from database by ORM, DB::select() or any other way.
Then use Tree::factory() method to provide module received data. This method receives arrays or any traversable objects, so you can provide it Database_Result object or an array(Note, that if you use array, you shuold use chaining method ->type(Tree::ARR) ).

After that, you should set callback function using ->callback('process_leaf') method.
This function will receive Tree_Leaf object and should return html code for current leaf.

Then just call ->make() method to create tree and use ->get($attributes) method to get your html code!

Notes

Methods factory(), data(), id(), parent_id(), type(), callback() and make() are chainable.
In Tree_leaf object, your data will be in object property (if you used Objects) or data property (if factory() received array).
You can change 'id' and 'parent_id' (theese are default ones) properties to look for in your data by methods id() and parent_id().
