为 Fluent 验证规则添加了新的静态构造函数

在 Laravel 9.41 中，我们现在为枚举规则、文件和图像文件添加了一些方便的静态构造函数。

您可以直接构造这些规则对象，但我喜欢知道可以通过主 Rule 对象上的静态构造函数访问它们的便利性。

use Illuminate\Validation\Rule;
use Illuminate\Validation\Rules\Enum;
use Illuminate\Validation\Rules\File;
use Illuminate\Validation\Rules\ImageFile;
 
// Before
(new File())->default();
(new ImageFile())->dimensions(
    Rule::dimensions()->maxWidth(1000)->maxHeight(500)
);
new Enum(PostStatus::class);
 
// As of 9.41
Rule::file()->default()
Rule::imageFile()->dimensions(
    Rule::dimensions()->maxWidth(1000)->maxHeight(500)
);
Rule::enum(PostStatus::class);

以下是一个更完整的示例，展示如何使用主 Rule 类静态方法进行验证规则。

use App\Models\Post;
use Illuminate\Validation\Rule;
use Illuminate\Validation\Rules\Enum;
use Illuminate\Validation\Rules\Unique;
 
// Before
$request->validate([
    'status' => [
        'required',
        new Enum(PostStatus::class)
    ],
    'slug' => [
        'required',
        new Unique(Post::class);
    ],
]);
 
// After
$request->validate([
    'status' => [
        'required',
        // Newly added in 9.41
        Rule::enum(PostStatus::class)
    ],
    'slug' => [
        'required',
        // Note: unique has been available for a while
        Rule::unique(Post::class),
    ],
]);
