If you are migrating from Spiral Framework 2.x, and you want to continue using the old filters you can use the spiral/filters-bridge package in this case.
The package spiral/filters-bridge provides support for request validation, composite validation, an error message
mapping and locations, etc.
Make sure that your server is configured with the following PHP version and extensions:
To install the package:
composer require spiral/filters-bridge
Note
The package will automatically install and configure thespiral/validatorpackage.
The package does not require any configuration and can be activated using the
bootloader Spiral\Filters\Bootloader\FiltersBootloader:
public function defineBootloaders(): array
{
    return [
        // ...
        \Spiral\Filters\Bootloader\FiltersBootloader::class,
        // ...
    ];
}
Read more about bootloaders in the Framework — Bootloaders section.
There is no difference between using the spiral/filters component and the spiral/filters-bridge package, so you can use
documentation for the previous Spiral version.
