laravel-oop-validator
=====================

[](#laravel-oop-validator)

Package was created for Laravel developers who need for some reason object-oriented approach to validation. It basically maps all string rules into easy manageable chained methods.

Installation
------------

[](#installation)

Use composer:

```
composer require krzysztofrewak/laravel-oop-validator

```

Usage
-----

[](#usage)

Most of the Laravel validation rules were mapped into `Field` methods. You can use `ValidationBuilder` or `PipelinedValidationBuilder` instances: first one will return rules in arrayed form, second one in string pipeline.

### Simple rule chains

[](#simple-rule-chains)

```
$validator->validate("email", function (Field $field): void {
    $field->string()->required()->email(["rfc"])
});

$validator->getRules();
```

```
// for ValidationBuilder: ["email" => ["string", "required", "email:rfc"]]
// for PipelinedValidationBuilder: ["email" => "string|required|email:rfc"]
```

### More complex rule chains

[](#more-complex-rule-chains)

```
$validator->validate("avatar", function (Field $field): void {
    $field->required()
        ->mimes(["jpeg", "png"])
        ->unique("users", "avatar")
        ->dimensions(function(Dimensions $dimensions): void {
			$dimensions->ratio(3/2);
		});
});

$validator->getRules();
```

```
// for ValidationBuilder: ["avatar" => ["required", "mimes:jpeg,png", "unique:users,avatar", "dimensions:ratio=1.5"]]
// for PipelinedValidationBuilder: ["avatar" => "required|mimes:jpeg,png|unique:users,avatar|dimensions:ratio=1.5"]
```

### Nested rules chains

[](#nested-rules-chains)

Nested validation rules could look like this:

```
$validator = new ValidationBuilder();
$validator->validateEach("tags", function (Field $field): void {
    $field->array();
});
$validator->validateInEach("id", "tags", function (Field $field): void {
    $field->required()->exists("tags", "id");
});
```

```
// for ValidationBuilder: ["tags.*:" => ["array"], "tags.*.id:" => ["required", "exists:tags,id"]]
// for PipelinedValidationBuilder: ["tags.*:" => "array", "tags.*.id:" => "required|exists:tags,id"]
```

### Custom rules chains

[](#custom-rules-chains)

Custom validation rules could look like this:

```
$validator = new ValidationBuilder();
$validator->validate("field", function (Field $field): void {
    $field->required()->customRule(CustomRule::class);
});
```

```
// for ValidationBuilder: ["field" => ["required", CustomRule::class]]
// for PipelinedValidationBuilder it will throw NotAllowedRuleException()
```

Laravel integration
-------------------

[](#laravel-integration)

You can add instance of `ValidationBuilder` into your `FormRequest`'s `rules()` method or any other place where you can put array of rules:

```
