feature#4233 2.5 Validation API changes (nicolassing, lashae, Rootie, weaverryan)
This PR was merged into the 2.5 branch.Discussion----------2.5 Validation API changes| Q | A| ------------- | ---| Doc fix? | no| New docs? | yes| Applies to | 2.5| Fixed tickets |#4094Hi guys!This takes the work in#4056,#4105 and#4161 and extends it based on some feedback. Basically, the whole validation stuff is quite difficult, because:A) We want to show the non-deprecated methods so people use the new stuffB) We don't want to confuse users on the 2.4 API (even though this number of users should be very small, as it would require you to have started a project in the past and be using 5.3.9 and lower#4105 (comment))This solution is to show the new way, but always show the old way in comments. This would check of A and B in#4094.Thanks!Commits-------9874d8e [#4233][#4094] Making validateValue and validate changes94fc520 Minor tweaks and a missing location thanks to xabbuh and WouterJf97ba7a Fixes thanks to@xabbuh279d8d6 Adding a section about keeping BC in a re-usable bundle280440e Adding details about the 2.4 API as commentse658b56 added a versionadded comment to Callback.rst70c5ca1 Update custom_contraint.rst to meet the new 2.5 api5dfe499 Don't use deprecated functions in Callback.rstf4380ed Update Callback.rst042dcf9 Replace addViolationAt (deprecated) by buildViolation

Custom Validation Constraints
339+
-----------------------------
340+
341+
Starting with Symfony 2.5, a new Validation API was introduced. In fact,
342+
there are 3 modes, which the user can configure in their project:
343+
344+
* 2.4: the original 2.4 and earlier validation API;
345+
* 2.5: the new 2.5 and later validation API;
346+
* 2.5-BC: the new 2.5 API with a backwards-compatible layer so that the
347+
2.4 API still works. This is only available in PHP 5.3.9+.
348+
349+
As a bundle author, you'll want to support *both* API's, since some users
350+
may still be using the 2.4 API. Specifically, if your bundle adds a violation
351+
directly to the:class:`Symfony\\Component\\Validator\\Context\\ExecutionContext`
352+
(e.g. like in a custom validation constraint), you'll need to check for which
353+
API is being used. The following code, would work for *all* users::
354+
355+
use Symfony\Component\Validator\ConstraintValidator;
356+
use Symfony\Component\Validator\Constraint;
357+
use Symfony\Component\Validator\Context\ExecutionContextInterface;
358+
// ...
359+
360+
class ContainsAlphanumericValidator extends ConstraintValidator
361+
{
362+
public function validate($value, Constraint $constraint)
363+
{
364+
if ($this->context instanceof ExecutionContextInterface) {
365+
// the 2.5 API
366+
$this->context->buildViolation($constraint->message)
367+
->setParameter('%string%', $value)
368+
->addViolation();
369+
);
370+
} else {
371+
// the 2.4 API
372+
$this->context->addViolation(
373+
$constraint->message,
374+
array('%string%' => $value)
375+
);
376+
}
377+

The ``validate`` method does not return a value; instead, it adds violations
79-
to the validator's ``context`` property with an ``addViolation`` method
80-
call if there are validation failures. Therefore, a value could be considered
81-
as being valid if it causes no violations to be added to the context.
82-
The first parameter of the ``addViolation`` call is the error message to
83-
use for that violation.
85+
Inside ``validate``, you don't need to return a value. Instead, you add violations
86+
to the validator's ``context`` property and a value will be considered valid
87+
if it causes no violations. The ``buildViolation`` method takes the error
88+
message as its argument and returns an instance of
89+
:class:`Symfony\\Component\\Validator\\Violation\\ConstraintViolationBuilderInterface`.
90+
The ``addViolation`` method call finally adds the violation to the context.
