README

Note: currently only works for validator component 2.2.x

Prioritised chain of validator constraints in Symfony2 validator component. Adds the ability to stop further validation based on a queue on constraints. Example use case: validating variable is an array, then validate the array contains a key. Default Symfony validator component behaviour is to complete every validation constraint.

Install

Add markwilson/symfony2-validator-priority-chain to composer.json requires.

Usage

PriorityChain requires a constraint option which takes either an array (ordered highest priority first), or a SplPriorityQueue. Each item in the queue must be a Constraint instance. By default, the validator will loop through each constraint until an error occurs (this can be changed with the stopOnError option).

e.g.

use MarkWilson\Validator\Constraints\PriorityChain;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Validator\Validation;

$queue = new \SplPriorityQueue();
$queue->insert(new Assert\Type('array'), 2);
$queue->insert(new Assert\NotBlank(), 1);

$constraint = new PriorityChain(array('constraints' => $queue));

$validator = Validation::createValidator();
$validator->validateValue($value, $constraint);
