Chapter 13: Data Validation 212 The notnull constraint also acts as an application level validator. This means that if Doctrine validators are turned on, Doctrine will automatically check that specified columns do not contain null values when saved. If those columns happen to contain null values Doctrine_Validator_Exception is raised. Email The e-mail validator simply validates that the inputted value is indeed a valid e-mail address and that the MX records for the address domain resolve as a valid e-mail address. Listing 13-6 // models/User.php class User extends BaseUser { // ... public function setTableDefinition() { parent::setTableDefinition(); // ... } } $this->hasColumn('email', 'string', 255, array( 'email' => true ) ); Here is the same example in YAML format. You can read more about YAML in the YAML Schema Files (page 195) chapter: Listing 13-7 --- # schema.yml # ... User: columns: # ... email: type: string(255) email: true # ... Now when we try and create a user with an invalid email address it will not validate: Listing 13-8 // test.php // ... $user = new User(); $user->username = 'jwage'; $user->email = 'jonwage'; if ( ! $user->isValid()) { echo 'User is invalid!'; } ----------------- Brought to you by
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) 26. http://www.php.net/checkdnsrr ----------------- Brought to you by
