require_once 'DataObject.php'; require_once 'DataObject/Validate.php'; class User_Profile extends DataObject { protected function define() { $this->defineField('username', 'Username', 'string', array('required' => true)); } } // Instantiate the class $userProfile = new User_Profile(); // Set the username field value to an empty string $userProfile->username = ''; // Validate the data object if (!$userProfile->validate()) { // Display the validation errors print_r($userProfile->getValidationErrors()); }
require_once 'DataObject.php'; require_once 'DataObject/Validate.php'; class User_Profile extends DataObject { protected function define() { $this->defineField('email', 'Email', 'string', array('regex' => '/^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$/')); } } // Instantiate the class $userProfile = new User_Profile(); // Set the email field value to an invalid email address $userProfile->email = 'invalid_email'; // Validate the data object if (!$userProfile->validate()) { // Display the validation errors print_r($userProfile->getValidationErrors()); }In both examples, we are using the php DataObject Validate package library to validate the data object. We define the fields and validation rules in the `define()` method of the class. We then set the field values and validate the object using the `validate()` method. If there are any validation errors, we can display them using the `getValidationErrors()` method.
