cakephp/validation

Validator objects define the rules that apply to a set of fields. Validator objects contain a mapping between fields and validation sets. Creating a validator is simple:

use Cake\Validation\Validator;

$validator = new Validator();
$validator
 ->requirePresence('email')
 ->add('email', 'validFormat', [
 'rule' => 'email',
 'message' => 'E-mail must be valid'
 ])
 ->requirePresence('name')
 ->notEmptyString('name', 'We need your name.')
 ->requirePresence('comment')
 ->notEmptyString('comment', 'You need to give a comment.');

$errors = $validator->validate($_POST);
if ($errors) {
 // display errors.
}
