Install

Just run the composer require command from the Terminal:

$ composer require ukeloop/laravel-validation-rule-builder

Validation Rule Builder

You can define validation rules with method chain pattern.

use Illuminate\Support\Facades\Validator;
use Ukeloop\ValidationRuleBuilder\ValidationRuleBuilder;

Validator::make($input, [
    'title' => (new ValidationRuleBuilder())->required()->string()->max(255),
]);

You can use Laravel validation rules.

use Ukeloop\ValidationRuleBuilder\ValidationRuleBuilder;

$validationRule = new ValidationRuleBuilder();

$validationRule->required();
$validationRule->sometime();
$validationRule->nullable();

$validationRule->string();
$validationRule->integer();
$validationRule->numeric();
$validationRule->date();
$validationRule->bool();

$validationRule->min(8);
$validationRule->max(255);

$validationRule->email('strict', 'dns');

// etc ...

For other validation rules, please refer to the laravel docs.

Using Rule Objects

$validationRule->add(Password::min(8));

Using Closures

new ValidationRuleBuilder(
    function ($attribute, $value, $fail) {
        if ($value === 'foo') {
            $fail('The ' . $attribute . ' is invalid.');
        }
    }
);

Validation Rule Sets

Validation rule sets are created by combining laravel validation rules. This will help you can keep your project's validation rules more DRY.

e.g. Rule of email address

use Ukeloop\ValidationRuleBuilder\RuleSet;

class EmailRuleSet extends RuleSet
{
    public static function rules(): ValidationRuleBuilder
    {
        return new ValidationRuleBuilder('email:strict,dns,spoof');
    }
}

use Illuminate\Support\Facades\Validator;

Validator::make($input, [
    'email' => EmailRuleSet::rules()->somtime()->required(),
]);

e.g. Rule of password

use Ukeloop\ValidationRuleBuilder\RuleSet;

class PasswordRuleSet extends RuleSet
{
    public static function rules(): ValidationRuleBuilder
    {
        return new ValidationRuleBuilder(
            Password::min(8)
                ->letters()
                ->mixedCase()
                ->numbers()
                ->symbols()
        );
    }
}

use Illuminate\Support\Facades\Validator;

Validator::make($input, [
    'password' => PasswordRuleSet::rules()->required()->confirmed(),
]);
