When applied to an array (or Traversable object), this constraint allows you to apply a collection of constraints to each element of the array.
Applies to | property or method |
Options | |
Class | All |
Validator | AllValidator |
Suppose that you have an array of strings, and you want to validate each entry in that array:
# src/Acme/UserBundle/Resources/config/validation.yml
AcmeUserBundleEntityUser:
properties:
favoriteColors:
- All:
- NotBlank: ~
- Length:
min: 5
// src/Acme/UserBundle/Entity/User.php
namespace AcmeUserBundleEntity;
use SymfonyComponentValidatorConstraints as Assert;
class User
{
/**
* @AssertAll({
* @AssertNotBlank,
* @AssertLength(min = 5)
* })
*/
protected $favoriteColors = array();
}
<!-- src/Acme/UserBundle/Resources/config/validation.xml -->
<?xml version="1.0" encoding="UTF-8" ?>
<constraint-mapping xmlns="http://symfony.com/schema/dic/constraint-mapping"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://symfony.com/schema/dic/constraint-mapping http://symfony.com/schema/dic/constraint-mapping/constraint-mapping-1.0.xsd">
<class name="AcmeUserBundleEntityUser">
<property name="favoriteColors">
<constraint name="All">
<option name="constraints">
<constraint name="NotBlank" />
<constraint name="Length">
<option name="min">5</option>
</constraint>
</option>
</constraint>
</property>
</class>
</constraint-mapping>
// src/Acme/UserBundle/Entity/User.php
namespace AcmeUserBundleEntity;
use SymfonyComponentValidatorMappingClassMetadata;
use SymfonyComponentValidatorConstraints as Assert;
class User
{
public static function loadValidatorMetadata(ClassMetadata $metadata)
{
$metadata->addPropertyConstraint('favoriteColors', new AssertAll(array(
'constraints' => array(
new AssertNotBlank(),
new AssertLength(array('min' => 5)),
),
)));
}
}
Now, each entry in the favoriteColors
array will be validated to not
be blank and to be at least 5 characters long.
type: array
[default option]
This required option is the array of validation constraints that you want to apply to each element of the underlying array.
type: mixed
default: null
2.6 新版功能: The payload
option was introduced in Symfony 2.6.
This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to.
For example, you may want to used several error levels to present failed constraint differently in the front-end depending on the severity of the error.
