Chapter 13: Data Validation 225
// models/User.php
Listing
13-46
class User extends BaseUser
{
// ...
public function setTableDefinition()
{
parent::setTableDefinition();
// ...
}
}
$this->hasColumn('age', 'integer', 3, array(
'unsigned' => true
)
);
Here is the same example in YAML format. You can read more about YAML in the YAML
Schema Files (page 195) chapter:
---
# schema.yml
Listing
13-47
# ...
User:
columns:
# ...
age:
type: integer(3)
unsigned: true
# ...
Now if I try and save a User with a negative age the validation will fail:
// test.php
Listing
13-48
// ...
$user = new User();
$user->username = 'jwage';
$user->age = '-100';
if ( ! $user->isValid()) {
echo 'User is invalid because -100 is signed';
}
US State
The us state validator checks that the given string is a valid US state code.
// models/State.php
Listing
13-49
class State extends Doctrine_Record
{
public function setTableDefinition()
{
