Chapter 13: Data Validation 214
# ...
notblank: true
Now if we try and save a User record with a username that is a single blank white space,
validation will fail:
Listing
13-12
// test.php
// ...
$user = new User();
$user->username = ' ';
if ( ! $user->isValid()) {
echo 'User is invalid!';
}
No Space
The no space validator is simple. It checks that the value doesn't contain any spaces.
Listing
13-13
// models/User.php
class User extends BaseUser
{
// ...
public function setTableDefinition()
{
parent::setTableDefinition();
// ...
}
}
$this->hasColumn('username', 'string', 255, array(
'nospace' => true
)
);
Listing

Listing
13-15
Here is the same example in YAML format. You can read more about YAML in the YAML
Schema Files (page 195) chapter:
---
# schema.yml
# ...
User:
columns:
username:
type: string(255)
nospace: true
# ...
Now if we try and save a User with a username that has a space in it, the validation will fail:
$user = new User();
$user->username = 'jon wage';
