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
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
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
