convalida zf2: come posso convalidare i campi dipendenti?

Question

Come posso impostare un filtro di input che dipende da un altro campo di input. Voglio verificare che il campo 'apDepTime' sia più di 'apArrTime'.

Come posso gestire questa situazione in ZF2?

Vorrei anche notare che sto usando 'Validatore di date'.

per favore mi aiuti a nessuno.

Answer 1

È possibile utilizzare la Zend\Validator\Callback validatore per questo

Il primo parametro passato al callback è il valore dell'input a cui è applicato il validatore.

Il secondo parametro è un array di altri valori di modulo immessi dai nomi di input e rappresenta il contesto in cui si desidera confrontare i valori.

Come semplice esempio ...

$apArrInputFilter->add($factory->createInput(array(
     'name' => 'apArrTime', 
     'required' => true, 
     'validators' => array(
       array(
        'name' => 'Callback', 
        'options' => array(
         'messages' => array(
          \Zend\Validator\Callback::INVALID_VALUE => 'The departure time is less than the arrival time', 
         ), 
         'callback' => function($value, $context=array()) { 
          // value of this input 
          $apArrTime = $value; 
          // value of input to check against from context 
          $apDepTime = $context['apDepTime']; 
          // compare times, eg.. 
          $isValid = $apDepTime > $apArrTime; 
          return $isValid; 
         }, 
        ), 
       ), 
     ), 
    ))); 

Ovviamente avrete bisogno di scrivere il codice per le vostre esigenze per il confronto data effettiva, ma che dovrebbe iniziare.

Answer 2

Si potrebbe anche utilizzare un approccio diverso. Usa un InputFilter per definire la tua funzione isValid().

Dillo tu sei forma di utilizzare un InputFilter.

$this->setInputFilter(new Filter\MyFilter()); 

Implementare la propria funzione isValid().

namespace Application\Form\Filter; 

use Zend\InputFilter\InputFilter; 
use Zend\Validator; 
use Zend\Filter; 

class MyFilter extends InputFilter 
{ 
    public function isValid($context = null) 
    { 
     // add your dependent validation 
    } 

    public function __construct() 
    { 
     // Add youre form field validations 
    }
