Using PHP BackedEnum as Route Requirements
Contributed by Thomas Calvet
in #45803.
In PHP, backed enumerations are enumerations where all its elements are backed by some scalar value. This makes them useful to restrict the possible values of some routing parameter. In previous Symfony versions, you had to create the requirements manually using public constants:
#[Route('/foo/{bar}', requirements: ['bar' => SomeEnum::AAA.'|'.SomeEnum::BBB])]
In Symfony 6.1, we're improving the Routing component to fully support \BackedEnum objects as follows:
use Symfony\Component\Routing\Requirement\EnumRequirement;
// 'bar' parameter allows all values defined in the Enum
[Route('/foo/{bar}', requirements: ['bar' => new EnumRequirement(SomeEnum::class)])]
// 'bar' parameter only allows certain values of those defined in the Enum
[Route('/foo/{bar}', requirements: ['bar' => new EnumRequirement(SomeEnum::class, SomeEnum::Aaa, SomeEnum::Bbb)])]
A Collection of Common Routing Requirements
Contributed by Thomas Calvet
in #45528.
When defining routes, there are some requirements that repeat on many projects. For example, restricting some value to be an integer, or a date or a valid UUID pattern. In Symfony 6.1 we're introducing a Requirement enumeration to define all those common routing requirements so you can use them in your projects:
use Symfony\Component\Routing\Requirement\Requirement;
[Route('/users/{id}', requirements: ['id' => Requirement::UUID_V4])]
[Route('/users/{id}')]
[Route('/posts/{date}/{slug}', requirements: [
'date' => Requirement::DATE_YMD,
'slug' => Requirement::ASCII_SLUG,
])]
// 'CATCH_ALL' is equivalent to '.+' (accepts all characters, including '/')
[Route('/category/{name}', requirements: ['name' => Requirement::CATCH_ALL])]
UTF-8 Parameter Names
Contributed by Nicolas Grekas
in #45054.
In PHP, variable identifiers can contain UTF-8 characters (e.g. $iñtërnâtiónàlizætiøn = '...') However, parameters in Symfony routes could only include ASCII characters. In Symfony 6.1 we're improving the Routing component to allow using UTF-8 characters in all route parameters:
use Symfony\Component\Routing\Annotation\Route;
[Route('/blog/{föo}/{bár}', name: '...')]
public function someControllerMethod(string $föo, string $bár) { // ... }
