* Type names were deprecated and will be removed in Symfony 3.0. Instead of
47+
referencing types by name, you should reference them by their
48+
fully-qualified class name (FQCN) instead. With PHP 5.5 or later, you can
49+
use the "class" constant for that:
50+
51+
Before:
52+
53+
```php
54+
$form = $this->createFormBuilder()
55+
->add('name', 'text')
56+
->add('age', 'integer')
57+
->getForm();
58+
```
59+
60+
After:
61+
62+
```php
63+
use Symfony\Component\Form\Extension\Core\Type\IntegerType;
64+
use Symfony\Component\Form\Extension\Core\Type\TextType;
65+
66+
$form = $this->createFormBuilder()
67+
->add('name', TextType::class)
68+
->add('age', IntegerType::class)
69+
->getForm();
70+
```
71+
72+
As a further consequence, the method `FormTypeInterface::getName()` was
73+
deprecated and will be removed in Symfony 3.0. You should remove this method
74+
from your form types.
75+
76+
If you want to customize the block prefix of a type in Twig, you should now
77+
implement `FormTypeInterface::getBlockPrefix()` instead:
78+
79+
Before:
80+
81+
```php
82+
class UserProfileType extends AbstractType
83+
{
84+
public function getName()
85+
{
86+
return 'profile';
87+
}
88+
}
89+
```
90+
91+
After:
92+
93+
```php
94+
class UserProfileType extends AbstractType
95+
{
96+
public function getBlockPrefix()
97+
{
98+
return 'profile';
99+
}
100+
}
101+
```
102+
103+
If you don't customize `getBlockPrefix()`, it defaults to the class name
104+
without "Type" suffix in underscore notation (here: "user_profile").
105+
106+
If you want to create types that are compatible with Symfony 2.3 up to 2.8
107+
and don't trigger deprecation errors, implement *both* `getName()` and
108+
`getBlockPrefix()`:
109+
110+
```php
111+
class ProfileType extends AbstractType
112+
{
113+
public function getName()
114+
{
115+
return $this->getBlockPrefix();
116+
}
117+
118+
public function getBlockPrefix()
119+
{
120+
return 'profile';
121+
}
122+
}
123+
```
124+
125+
If you define your form types in the Dependency Injection configuration, you
126+
should further remove the "alias" attribute:
127+
128+
Before:
129+
130+
```xml
131+
<service id="my.type" class="Vendor\Type\MyType">
132+
<tag name="form.type" alias="mytype" />
133+
</service>
134+
```
135+
136+
After:
137+
138+
```xml
139+
<service id="my.type" class="Vendor\Type\MyType">
140+
<tag name="form.type" />
141+
</service>
142+
```
143+
144+
Type extension should return the fully-qualified class name of the extended
145+
type from `FormTypeExtensionInterface::getExtendedType()` now.
146+
147+
Before:
148+
149+
```php
150+
class MyTypeExtension extends AbstractTypeExtension
151+
{
152+
public function getExtendedType()
153+
{
154+
return 'form';
155+
}
156+
}
157+
```
158+
159+
After:
160+
161+
```php
162+
use Symfony\Component\Form\Extension\Core\Type\FormType;
163+
164+
class MyTypeExtension extends AbstractTypeExtension
165+
{
166+
public function getExtendedType()
167+
{
168+
return FormType::class;
169+
}
170+
}
171+
```
172+
173+
If your extension has to be compatible with Symfony 2.3-2.8, use the
174+
following statement:
175+
176+
```php
177+
use Symfony\Component\Form\AbstractType;
178+
use Symfony\Component\Form\Extension\Core\Type\FormType;
179+
180+
class MyTypeExtension extends AbstractTypeExtension
181+
{
182+
public function getExtendedType()
183+
{
184+
method_exists(AbstractType::class, 'getBlockPrefix') ? FormType::class : 'form';
185+
}
186+
}
187+
```
188+
189+
* Returning type instances from `FormTypeInterface::getParent()` is deprecated
190+
and will not be supported anymore in Symfony 3.0. Return the fully-qualified
191+
class name of the parent type class instead.
192+
193+
Before:
194+
195+
```php
196+
class MyType
197+
{
198+
public function getParent()
199+
{
200+
return new ParentType();
201+
}
202+
}
203+
```
204+
205+
After:
206+
207+
```php
208+
class MyType
209+
{
210+
public function getParent()
211+
{
212+
return ParentType::class;
213+
}
214+
}
215+
```
216+
217+
* Passing type instances to `Form::add()`, `FormBuilder::add()` and the
218+
`FormFactory::create*()` methods is deprecated and will not be supported
219+
anymore in Symfony 3.0. Pass the fully-qualified class name of the type
220+
instead.
221+
222+
Before:
223+
224+
```php
225+
$form = $this->createForm(new MyType());
226+
```
227+
228+
After:
229+
230+
```php
231+
$form = $this->createForm(MyType::class);
232+
```
