- // Author: Maxim Poltarak <maxx at e dash taller dot net>
- // WWW: http://dev.e-taller.net/dbtree/
- // Category: Databases
- // Description: PHP class implementing a Nested Sets approach to storing
- // tree-like structures in database tables. This technique was
- // introduced by Joe Celko <http://www.celko.com/> and has some
- // advantages over a widely used method called Adjacency Matrix.
- //****************************************************************************
- // The lib is FREEWARE. That means you may use it anywhere you want, you may
- // do anything with it. The Author mentioned above is NOT responsible for any
- // consequences of using this library.
- // If you don't agree with this, you are NOT ALLOWED to use the lib!
- //****************************************************************************
- // You're welcome to send me all improvings, feature requests, bug reports...
- //****************************************************************************
- // SAMPLE DB TABLE STRUCTURE:
- //
- // CREATE TABLE categories (
- // cat_id INT UNSIGNED NOT NULL AUTO_INCREMENT,
- // cat_left INT UNSIGNED NOT NULL,
- // cat_right INT UNSIGNED NOT NULL,
- // cat_level INT UNSIGNED NOT NULL,
- // PRIMARY KEY(cat_id),
- // KEY(cat_left, cat_right, cat_level)
- // );
- //
- // This is believed to be the optimal Nested Sets use case. Use `one-to-one`
- // relations on `cat_id` field between this `structure` table and
- // another `data` table in your database.
- //
- // Don't forget to make a single call to clear()
- // to set up the Root node in an empty table.
- //
- //****************************************************************************
- // NOTE: Although you may use this library to retrieve data from the table,
- // it is recommended to write your own queries for doing that.
- // The main purpose of the library is to provide a simpler way to
- // create, update and delete records. Not to SELECT them.
- //****************************************************************************
- //
- // IMPORTANT! DO NOT create either UNIQUE or PRIMARY keys on the set of
- // fields (`cat_left`, `cat_right` and `cat_level`)!
- // Unique keys will destroy the Nested Sets structure!
- //
- //****************************************************************************
- // CHANGELOG:
- // 16-Apr-2003 -=- 1.1
- // - Added moveAll() method
- // - Added fourth parameter to the constructor
- // - Renamed getElementInfo() to getNodeInfo() /keeping BC/
- // - Added "Sample Table Structure" comment
- // - Now it trigger_error()'s in case of any serious error, because if not you
- // will lose the Nested Sets structure in your table
- // 19-Feb-2004 -=- 1.2
- // - Fixed a bug in moveAll() method?
- // Thanks to Maxim Matyukhin for the patch.
- // 13-Jul-2004 -=- 1.3
- // - Changed all die()'s for a more standard trigger_error()
- // Thanks to Dmitry Romakhin for pointing out an issue with
- // incorrect error message call.
- // 09-Nov-2004 -=- 1.4
- // - Added insertNear() method.
- // Thanks to Michael Krenz who sent its implementation.
- // - Removed IGNORE keyword from UPDATE clauses in insert() methods.
- // It was dumb to have it there all the time. Sorry. Anyway, you had
- // to follow the important note mencioned above. If you hadn't, you're
- // in problem.
