||||
* The `UniversalClassLoader` class has been removed in favor of
|
||||
`ClassLoader`. The only difference is that some method names are different:

* The `DebugUniversalClassLoader` class has been removed in favor of
|
||||
`DebugClassLoader`. The difference is that the constructor now takes a
|
||||
loader to wrap.
|
||||
|
||||
### Console
|
||||
|
||||
* The `dialog` helper has been removed in favor of the `question` helper.
|
||||
|
||||
* The methods `isQuiet`, `isVerbose`, `isVeryVerbose` and `isDebug` were added
|
||||
to `Symfony\Component\Console\Output\OutputInterface`.
|
||||
|
||||
* `ProgressHelper` has been removed in favor of `ProgressBar`.

### DependencyInjection
|
||||
|
||||
* The methods `Definition::setFactoryClass()`,
|
||||
`Definition::setFactoryMethod()`, and `Definition::setFactoryService()` have
|
||||
been removed in favor of `Definition::setFactory()`. Services defined using
|

YAML or XML use the same syntax as configurators.

`ChoiceListInterface::getChoicesForValues()` and

`ChoiceListInterface::getValuesForChoices()` should be sufficient.

`Symfony\Component\Security\Csrf\CsrfTokenManagerInterface` instead.

* The options "`csrf_provider`" and "`intention`" were renamed to "`csrf_token_generator`"
|
||||

|
||||
|
||||
* The method `Form::getErrorsAsString()` was removed. Use `Form::getErrors()`
|
||||
instead with the argument `$deep` set to true and `$flatten` set to false
|
||||
and cast the returned iterator to a string (if not done implicitly by PHP).

### FrameworkBundle
|
||||
|
||||
* The `getRequest` method of the base `Controller` class has been deprecated
|
||||
since Symfony 2.4 and must be therefore removed in 3.0. The only reliable
|
||||
way to get the `Request` object is to inject it in the action method.

||||
|
||||
Before:

||||

||||

|
||||

$request = $this->getRequest();

}

||||
After:

use Symfony\Component\HttpFoundation\Request;

||||
{

||||
// ...
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
* The `request` service was removed. You must inject the `request_stack`
|
||||
service instead.
|
||||
|
||||
* The `enctype` method of the `form` helper was removed. You should use the
|
||||
new method `start` instead.

### HttpKernel
|
||||
|
||||
* The `Symfony\Component\HttpKernel\Log\LoggerInterface` has been removed in
|
||||

|
||||
names are different:

* `crit()` -> `critical()`

### Locale
|
||||
|
||||
* The Locale component was removed and replaced by the Intl component.

||||
Instead of the methods in `Symfony\Component\Locale\Locale`, you should use

||||
these equivalent methods in `Symfony\Component\Intl\Intl` now:
|
||||

* `Locale::getDisplayCountries()` -> `Intl::getRegionBundle()->getCountryNames()`

* The option "`methods`" of the `Callback` constraint was removed. You should
|
||||
use the option "`callback`" instead. If you have multiple callbacks, add
|
||||
multiple callback constraints instead.
|
||||
|
||||
Before (YAML):
|
||||
|
||||
```yaml
|
||||
constraints:
|
||||
- Callback: [firstCallback, secondCallback]
|
||||
```
|
||||
|
||||
After (YAML):
|
||||
|
||||
```yaml
|
||||
constraints:
|
||||
- Callback: firstCallback
|
||||
- Callback: secondCallback
|
||||
```
|
||||
|
||||
When using annotations, you can now put the `Callback` constraint directly on
|
||||
the method that should be executed.
|
||||
|
||||
Before (Annotations):
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\Constraints as Assert;
|
||||
use Symfony\Component\Validator\ExecutionContextInterface;
|
||||
|
||||
/**
|
||||
* @Assert\Callback({"callback"})

||||

|
||||
class MyClass
|
||||
{

||||
public function callback(ExecutionContextInterface $context)

||||
{

||||
// ...

||||
}
|
||||
}

|
||||
use Symfony\Component\Validator\Constraints as Assert;

use Symfony\Component\Validator\ExecutionContextInterface;

||||
class MyClass

||||

||||

|
||||

|
||||
public function callback(ExecutionContextInterface $context)

{
|
||||

||||
}
|
||||
}
|
||||
```
|
||||
|
||||
* The interface `ValidatorInterface` was replaced by the more powerful
|
||||
interface `Validator\ValidatorInterface`. The signature of the `validate()`
|
||||
method is slightly different in that interface and accepts a value, zero
|
||||
or more constraints and validation group. It replaces both
|
||||
`validate()` and `validateValue()` in the previous interface.
|
||||
|
||||
Before:
|
||||
|
||||
```php
|
||||
$validator->validate($object, 'Strict');
|
||||
|
||||
$validator->validateValue($value, new NotNull());
|
||||
```
|
||||
|
||||
After:
|
||||
|
||||
```php
|
||||
$validator->validate($object, null, 'Strict');
|
||||
|
||||
$validator->validate($value, new NotNull());
|
||||
```
|
||||
|
||||
Apart from this change, the new methods `startContext()` and `inContext()`
|
||||
were added. The first of them allows to run multiple validations in the
|
||||
same context and aggregate their violations:
|
||||
|
||||
```php
|
||||
$violations = $validator->startContext()
|
||||
->atPath('firstName')->validate($firstName, new NotNull())
|
||||
->atPath('age')->validate($age, new Type('integer'))
|
||||
->getViolations();
|
||||
```
|
||||
|
||||
The second allows to run validation in an existing context. This is
|
||||
especially useful when calling the validator from within constraint
|
||||
validators:
|
||||
|
||||
```php
|
||||
$validator->inContext($context)->validate($object);
|
||||
```
|
||||
|
||||
Instead of a `Validator`, the validator builder now returns a
|
||||
`Validator\RecursiveValidator` instead.
|
||||
|
||||
* The interface `ValidationVisitorInterface` and its implementation
|
||||
`ValidationVisitor` were removed. The implementation of the visitor pattern
|
||||
was flawed. Fixing that implementation would have drastically slowed down
|
||||
the validator execution, so the visitor was removed completely instead.
|
||||
|
||||
Along with the visitor, the method `accept()` was removed from
|
||||
`MetadataInterface`.
|
||||
|
||||
* The interface `MetadataInterface` was moved to the `Mapping` namespace.
|
||||
|
||||
Before:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\MetadataInterface;
|
||||
```
|
||||
|
||||
After:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\Mapping\MetadataInterface;
|
||||
```
|
||||
|
||||
The methods `getCascadingStrategy()` and `getTraversalStrategy()` were
|
||||
added to the interface. The first method should return a bit mask of the
|
||||
constants in class `CascadingStrategy`. The second should return a bit
|
||||
mask of the constants in `TraversalStrategy`.
|
||||
|
||||
Example:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\Mapping\TraversalStrategy;
|
||||
|
||||
public function getTraversalStrategy()
|
||||
{
|
||||
return TraversalStrategy::TRAVERSE;
|
||||
}
|
||||
```

||||
|
||||
* The interface `PropertyMetadataInterface` was moved to the `Mapping`
|
||||
namespace.
|
||||
|
||||
Before:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\PropertyMetadataInterface;
|
||||
```
|
||||
|
||||
After:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\Mapping\PropertyMetadataInterface;
|
||||
```
|
||||
|
||||
* The interface `PropertyMetadataContainerInterface` was moved to the `Mapping`
|
||||
namespace and renamed to `ClassMetadataInterface`.
|
||||
|
||||
Before:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\PropertyMetadataContainerInterface;
|
||||
```
|
||||
|
||||
After:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\Mapping\ClassMetadataInterface;
|
||||
```
|
||||
|
||||
The interface now contains four additional methods:
|
||||
|
||||
* `getConstrainedProperties()`
|
||||
* `hasGroupSequence()`
|
||||
* `getGroupSequence()`
|
||||
* `isGroupSequenceProvider()`
|
||||
|
||||
See the inline documentation of these methods for more information.
|
||||
|
||||
* The interface `ClassBasedInterface` was removed. You should use
|
||||
`Mapping\ClassMetadataInterface` instead:

||||
Before:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\ClassBasedInterface;
|
||||
|
||||
class MyClassMetadata implements ClassBasedInterface
|
||||
{
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
After:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\Mapping\ClassMetadataInterface;
|
||||
|
||||
class MyClassMetadata implements ClassMetadataInterface
|
||||
{
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
* The class `ElementMetadata` was renamed to `GenericMetadata`.
|
||||
|
||||
Before:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\Mapping\ElementMetadata;
|
||||
|
||||
class MyMetadata extends ElementMetadata
|
||||
{
|
||||
}
|
||||
```
|
||||
|
||||
After:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\Mapping\GenericMetadata;
|
||||
|
||||
class MyMetadata extends GenericMetadata
|
||||
{
|
||||
}
|
||||
```
|
||||
|
||||
* The interface `ExecutionContextInterface` and its implementation
|
||||
`ExecutionContext` were moved to the `Context` namespace.
|
||||
|
||||
Before:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\ExecutionContextInterface;
|
||||
```
|
||||
|
||||
After:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\Context\ExecutionContextInterface;
|
||||
```
|
||||
|
||||
The interface now contains the following additional methods:
|
||||
|
||||
* `getValidator()`
|
||||
* `getObject()`
|
||||
* `setNode()`
|
||||
* `setGroup()`
|
||||
* `markGroupAsValidated()`
|
||||
* `isGroupValidated()`
|
||||
* `markConstraintAsValidated()`
|
||||
* `isConstraintValidated()`
|
||||
|
||||
See the inline documentation of these methods for more information.
|
||||
|
||||
The method `addViolationAt()` was removed. You should use `buildViolation()`
|
||||
instead.
|
||||
|
||||
Before:
|
||||
|
||||
```php
|
||||
$context->addViolationAt('property', 'The value {{ value }} is invalid.', array(
|
||||
'{{ value }}' => $invalidValue,
|
||||
));
|
||||
```
|
||||
|
||||
After:
|
||||
|
||||
```php
|
||||
$context->buildViolation('The value {{ value }} is invalid.')
|
||||
->atPath('property')
|
||||
->setParameter('{{ value }}', $invalidValue)
|
||||
->addViolation();
|
||||
```
|
||||
|
||||
The methods `validate()` and `validateValue()` were removed. You should use
|
||||
`getValidator()` together with `inContext()` instead.
|
||||
|
||||
Before:
|
||||
|
||||
```php
|
||||
$context->validate($object);
|
||||
```
|
||||
|
||||
After:
|
||||
|
||||
```php
|
||||
$context->getValidator()
|
||||
->inContext($context)
|
||||
->validate($object);
|
||||
```
|
||||
|
||||
The parameters `$invalidValue`, `$plural` and `$code` were removed from
|
||||
`addViolation()`. You should use `buildViolation()` instead. See above for
|
||||
an example.
|
||||
|
||||
The method `getMetadataFactory()` was removed. You can use `getValidator()`
|
||||
instead and use the methods `getMetadataFor()` or `hasMetadataFor()` on the
|
||||
validator instance.
|
||||
|
||||
Before:
|
||||
|
||||
```php
|
||||
$metadata = $context->getMetadataFactory()->getMetadataFor($myClass);
|
||||
```
|
||||
|
||||
After:
|
||||
|
||||
```php
|
||||
$metadata = $context->getValidator()->getMetadataFor($myClass);
|
||||
```
|
||||
|
||||
* The interface `GlobalExecutionContextInterface` was removed. Most of the
|
||||
information provided by that interface can be queried from
|
||||
`Context\ExecutionContextInterface` instead.
|
||||
|
||||
* The interface `MetadataFactoryInterface` was moved to the `Mapping\Factory`
|
||||
namespace along with its implementations `BlackholeMetadataFactory` and
|
||||
`ClassMetadataFactory`. These classes were furthermore renamed to
|
||||
`BlackHoleMetadataFactory` and `LazyLoadingMetadataFactory`.
|
||||
|
||||
Before:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\Mapping\ClassMetadataFactory;
|
||||
|
||||
$factory = new ClassMetadataFactory($loader);
|
||||
```
|
||||
|
||||
After:
|
||||
|
||||
```php
|
||||
use Symfony\Component\Validator\Mapping\Factory\LazyLoadingMetadataFactory;
|
||||
|
||||
$factory = new LazyLoadingMetadataFactory($loader);
|
||||
```
|
||||
|
||||
* The option `$deep` was removed from the constraint `Valid`. When traversing
|
||||
arrays, nested arrays are always traversed (same behavior as before). When
|
||||
traversing nested objects, their traversal strategy is used.
|
||||
|
||||
* The method `ValidatorBuilder::setPropertyAccessor()` was removed. The
|
||||
validator now functions without a property accessor.
|
||||
|
||||
* The methods `getMessageParameters()` and `getMessagePluralization()` in
|
||||
`ConstraintViolation` were renamed to `getParameters()` and `getPlural()`.
|
||||
|
||||
Before:
|
||||
|
||||
```php
|
||||
$parameters = $violation->getMessageParameters();
|
||||
$plural = $violation->getMessagePluralization();
|
||||
```
|
||||
|
||||
After:
|
||||
|
||||
```php
|
||||
$parameters = $violation->getParameters();
|
||||
$plural = $violation->getPlural();
|
||||
```
|
||||
|
||||
### Yaml
|
||||
|
||||
* The ability to pass file names to `Yaml::parse()` has been removed.
|
||||
@ -434,3 +988,9 @@ UPGRADE FROM 2.x to 3.0
|
||||
```php
|
||||
Yaml::parse(file_get_contents($fileName));
|
||||
```
|
||||
|
||||
### Process
|
||||
|
||||
* `Process::setStdin()` and `Process::getStdin()` have been removed. Use
|
||||
`Process::setInput()` and `Process::getInput()` that works the same way.
|
||||
* `Process::setInput()` and `ProcessBuilder::setInput()` do not accept non-scalar types.
