Chapter 13: Data Validation 213
The above code will throw an exception because jonwage is not a valid e-mail address. Now
we can take this even further and give a valid e-mail address format but an invalid domain
name:
// test.php
Listing
13-9
// ...
$user = new User();
$user->username = 'jwage';
$user->email = 'jonwage@somefakedomainiknowdoesntexist.com';
if ( ! $user->isValid()) {
echo 'User is invalid!';
}
Now the above code will still fail because the domain
somefakedomainiknowdoesntexist.com does not exist and the php function
checkdnsrr() 26 returned false.
Not Blank
The not blank validator is similar to the not null validator except that it will fail on empty
strings or strings with white space.
// models/User.php
Listing
13-10
class User extends BaseUser
{
// ...
public function setTableDefinition()
{
parent::setTableDefinition();
// ...
}
}
$this->hasColumn('username', 'string', 255, array(
'notblank' => 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
13-11
# ...
User:
columns:
username:
type: string(255)
