require_once __DIR__ . '/vendor/autoload.php';

$data = ['name'=>'armia','age'=>''];
$result = \Validation\Validator::validate(
    [
        'name'=>[
            'rules'=>['Required','Max:20'],
            'messages'=>['custom required msg']
        ],
        'age'=>[
            'rules'=>['Required', 'Numeric'],
            'messages'=>['custom required msg','custom numeric msg']
        ]
    ],$data);
    
// Output: 
// [
//     [0] => [
//         [age] => custom required msg
//     ],
//     [1] => [
//         [age] => custom numeric msg
//     ]
// ]


// If all validation passes, you get an empty array
 

If you want to add custom validation, do so

    class Email implements \Validation\ValidationInterface{
    
        private array $formData;

        private array $errorMessage;
    
        private string $field;
    
        private string $additional;
    
        public function validate(){
            if(!filter_var($this->formData[$this->field], FILTER_VALIDATE_EMAIL)){
                return $this->errorMessage;
            }
        }
        
         public function formData(array $formData){
            $this->formData = $formData;
        }
        
        public function message(string $errorMessage){
            $this->errorMessage = [$this->field => empty($errorMessage) ? "The `{$this->field}` field is not an email" : $errorMessage];
        }
    
        public function field(string $field){
            $this->field = $field;
        }
        
        public function additionalData(string $additional)
        {
            $this->additional = $additional;
        }
    } 
    

Now you can use the Email class like this

require_once __DIR__ . '/vendor/autoload.php';
require_once 'Email.php';

$formData = ['email'=>'armia@gmail.com'];
$result = \Validation\Validator::validate(
    [
        'email'=>[
            'rules'=>['Required','Email']
        ],
    ],$data);

//Output: 
//[] 
//If all validation passes, you get an empty array

Regex:pattern

The field under validation must match the given regular expression.

$data = ['password'=>'123456','age'=>''];
$result = \Validation\Validator::validate(
    [
        'password'=>[
            'rules'=>['Regex:/[1-6]/']
        ]
    ],$data);
