Simple Examples

This is a simple example of a single ORM model, that has no relationships, but uses validation on the fields.

SQL schema

CREATE TABLE IF NOT EXISTS `members` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(32) NOT NULL,
  `first_name` varchar(32) NOT NULL,
  `last_name` varchar(32) NOT NULL,
  `email` varchar(127) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;

Model

<?php defined('SYSPATH') or die('No direct access allowed.');

class Model_Member extends ORM {

    public function rules()
    {
        return array(
            'username' => array(
                array('not_empty'),
                array('min_length', array(':value', 4)),
                array('max_length', array(':value', 32)),
                array('regex', array(':value', '/^[-\pL\pN_.]++$/uD')),
            ),
            'first_name' => array(
                array('not_empty'),
                array('min_length', array(':value', 4)),
                array('max_length', array(':value', 32)),
                array('regex', array(':value', '/^[-\pL\pN_.]++$/uD')),
            ),
            'last_name' => array(
                array('not_empty'),
                array('min_length', array(':value', 4)),
                array('max_length', array(':value', 32)),
                array('regex', array(':value', '/^[-\pL\pN_.]++$/uD')),
            ),
            'email' => array(
                array('not_empty'),
                array('min_length', array(':value', 4)),
                array('max_length', array(':value', 127)),
                array('email'),
            ),
        );
    }
}

The array returned by ORM::rules() will be passed to a Validation object and tested when you call ORM::save().

Please notice that defining the primary key "id" in the model is not necessary. Also the table name in the database is plural and the model name is singular.

Controller

<?php defined('SYSPATH') or die('No direct access allowed.');

class Controller_Member extends Controller_Template {

    public function action_index()
    {
        /**
         * Example 1
         */

        // Create an instance of a model
        $members = ORM::factory('Member');

        // Get all members with the first name "Peter" find_all()
        // means we get all records matching the query.
        $members->where('first_name', '=', 'Peter')->find_all();

        // Count records in the $members object
        $members->count_all();

        /**
         * Example 2
         */

        // Create an instance of a model
        $member = ORM::factory('Member');

        // Get a member with the user name "bongo" find() means
        // we only want the first record matching the query.
        $member->where('username', '=', 'bongo')->find();

        /**
         * Example 3
         */

        // Create an instance of a model
        $member = ORM::factory('Member');

        // Do an INSERT query
        $member->username = 'bongo';
        $member->first_name = 'Peter';
        $member->last_name = 'Smith';
        $member->save();

        /**
         * Example 4
         */

        // Create an instance of a model where the
        // table field "id" is "1"
        $member = ORM::factory('Member', 1);

        // Do an UPDATE query
        $member->username = 'bongo';
        $member->first_name = 'Peter';
        $member->last_name = 'Smith';
        $member->save();
    }
}

$member will be a PHP object where you can access the values from the query e.g. echo $member->first_name
