3. Other changes

Yii Validator version 2.6.0 was released.

This release adds a new File validator, extends Image validator input support, and includes translation, documentation, and internal code quality improvements.

File validator ¶

The new File rule validates that a value is a file. It supports:

• string file paths;
• SplFileInfo instances;
• PSR-7 UploadedFileInterface instances.

It can also check allowed extensions, MIME types, and file size.

use Yiisoft\Validator\Rule\File;
use Yiisoft\Validator\Validator;

$result = (new Validator())->validate(
    ['avatar' => $request->getUploadedFiles()['avatar'] ?? null],
    [
        'avatar' => new File(
            extensions: ['jpg', 'png', 'webp'],
            mimeTypes: ['image/jpeg', 'image/png', 'image/webp'],
            maxSize: 2_000_000,
        ),
    ],
);

For multiple files, use it together with Each:

use Yiisoft\Validator\Rule\Each;
use Yiisoft\Validator\Rule\File;

$rules = [
    'attachments' => new Each(
        new File(
            extensions: ['pdf', 'txt'],
            maxSize: 5_000_000,
        ),
    ),
];

Optional upload fields can use skipOnEmpty:

use Yiisoft\Validator\Rule\File;

$rule = new File(skipOnEmpty: true);

SplFileInfo support in Image validator ¶

Image validator now accepts SplFileInfo values directly. This is useful when your application already works with filesystem objects instead of plain paths.

use SplFileInfo;
use Yiisoft\Validator\Rule\Image\Image;
use Yiisoft\Validator\Validator;

$result = (new Validator())->validate(
    new SplFileInfo(__DIR__ . '/avatar.jpg'),
    new Image(
        minWidth: 128,
        minHeight: 128,
        maxWidth: 2048,
        maxHeight: 2048,
	),
);

The Image validator was also fixed to handle unreadable streams correctly.

Other changes ¶

• Updated Polish translations.
• Explicitly imported classes, functions, and constants in use sections.
• Fixed translations, documentation grammar, incorrect imports, and a broken contributing guide link.
