Composite Validation Rules

June 25, 2019 / Paul Redmond

Validation Composite is a package by Paul Klimov that allows uniting several validation rules into a single one for easy reuse.

Here are a few simple examples that will help visualize how this package works. Let’s say you want to centralize your password or avatar rules into one composite rule:

<?php

namespace App\Rules;

use Illuminatech\Validation\Composite\CompositeRule;

class PasswordRule extends CompositeRule
{
    protected function rules(): array
    {
        return ['string', 'min:8', 'max:200'];
    }
}

class AvatarRule extends CompositeRule
{
    protected function rules(): array
    {
        return ['file', 'mimes:png,jpg,jpeg', 'max:1024'];
    }
}

Example usage of these composite rules looks like this in a controller:

public function update(Request $request)
{
    $validatedData = $request->validate([
        'password' => ['required', new PasswordRule],
        'avatar' => ['required', new AvatarRule],
        // ...
    ]);

    // ...
}
