Easy to use Validation package for Fatfree-framework with using F3 built-in translations. You can also use it directly in the model.

NOTE: This package port some classes and ideas from illuminate/validator.
NOTE: SAMPLE DICT/LANG FILE IS INCLUDED AS en.php.sample, use this for reference.

## Usage

• 1: Initializing, passing data and validate:

  `$validator = new Validator(

    array('name' => 'Anand Pilania', 'email' => '[email protected]'),
    
    array('name' => 'required|min:3|max:60', 'email' => 'required|unique:Models\User|email')
  

  )->validate();`

  NOTE: You can also pass more data to the validate method.

  • Another method:

    `$validator = Validator::instance()->validate(

      array('name' => 'Anand Pilania', 'email' => '[email protected]'),
      
      array('name' => 'required|min:3|max:60', 'email' => 'required|unique:NAMESPACED_MODEL_CLASS_OR_CONFIG_MODEL.PARAM`|email')
    

    );`

• 2: Get validation status (return -> true/false):

  $validator->passed();

• 3: If validation failed, retrieve the failed attribute with formatted messages/errors (return -> array):

  $validator->errors();

• composer require anandpilania/f3-validator

• boolean OR bool, string, integer OR int, array, numeric, alpha, alpha_num, alpha_dash,
• url, nullable, json, required, confirmed, active_url, email, ip, ipv4, ipv6, filled

• min, max, size, between - min:6, max:255, size:3, between:1,3
• unique - unique:NAMESPACED_MODEL_CLASS_OR_CONFIG_MODEL
• ...

• RECOMMENDED : Validate user input in controllers is the recommended way

`$validator = Validator::instance()->validate($f3->get('POST'), array(
	'field' => 'required|CHECK_PARAM' // EG: 'email' => 'required|email|unique:Models\User'
));`

`if(!$validator->passed()) {
	return/flash $validator->errors();
}`

• You can also use this validator directly into your model: FOR EX: Validatin on beforesave trigger: (This example is used with ikkez/f3-cortex)

`protected $validator;
 public function __construct() {
      parent::__construct();
      $saveHandler = function() {
	       foreach($this->getFieldConfiguration() as $field => $conf) {
        	    if(isset($conf['validate'])) {
            	    $rules[$field] = $conf['validate'];
            	    $data[$field] = $this->get($field);
            	    if(Validator::instance()->str_contains($conf['validate'], 'confirmed')) {
        	    	   $confirmation = $field.'_confirmation';
                	   $data[$field.'_confirmation'] = null !== $f3->get('POST.'.$confirmation)?$f3->get('POST.'.$confirmation):$f3->get('GET.'.$confirmation);
            	    }
        	    }
    	    }
    	    $this->validator = Validator::instance()->validate($data, $rules);
	        return $this->validator->passed();
	   };
   $this->beforesave($saveHandler);
}`

`$model = new MODEL;
 $model->copyFrom($f3->get('POST'), array_keys($model->fieldConf));
 $mode->save();
 
 if($model->validator->passed()) {
 	// NO ERRORS
 }else{
 	// VAIDATION FAILED
	$errors = $model->validator->errors();
 }`

• Simply pass the NAMESPACED_MODEL_CLASS => unique:Models\User

• Define in config as =>

  INI => MODEL.USERS = Models\User HIVE => $f3->set('MODEL.USERS', 'Models\User');

  and use it as unique:users
