Laravel Castable
Laravel Castable package is a type converter, input filter or sanitizer. It is possible to do all of these operations. Supported POST, RAW DATA, GET requests methods. We started by inspiring the Laravel Eloquent data cast., (*2)
Requirements
PHP 5.6, 7.0+
Laravel 5.3 (LTS) or Laravel 5.4 (Current), (*3)
Get Started
Firstly, we install package:, (*4)
$ composer require atayahmet/laravel-castable
and then we need add the service provider to the app.php, (*5)
Castable\CastableServiceProvider::class
OK, we done., (*6)
Let's see how to use the laravel-castable., (*7)
Castable types
| Types |
| string |
| integer |
| boolean |
| float |
| double |
| real |
| unset |
| array |
| object (stdClass) |

We created new artisan command that inspired make:request from laravel built in command., (*8)
$ php artisan make:cast ContactRequest
New form of the form request class:, (*9)
<?php
namespace App\Http\Requests;
use Castable\Castable;
class ContactRequest extends Castable
{
protected $casts = [
'json' => [
//
],
'post' => [
'name' => 'string',
'age' => 'integer',
'student' => 'boolean',
'interests' => 'collection'
],
'query' => [
'save' => 'boolean'
]
];
/**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize()
{
return false;
}
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
return [
//
];
}
}
We added four inputs to casts property, status attibute added to query string parameters and age, student and interests attributes added to post parameters., (*10)

To get the above result for:, (*13)

public index(ContactRequest $contactRequest)
{
$contactRequest->cast()->input();
}
}
Get a input:, (*14)
$contactRequest->cast()->input('interests'); // collection
$contactRequest->cast()->input('student') // boolean (true)
$contactRequest->cast()->input('save') // boolean (true)
````
if request is post raw data:
```php
$contactRequest->cast()->json();
$contactRequest->cast()->json('age');
````
**Get original inputs:**
```php
$contactRequest->input();
Get original an input:, (*15)
$contactRequest->input('student'); // string (true)

$contactRequest->json();
You can add presenter to the all post, query and json inputs. This feature gives you a chance to filter inputs., (*17)
Add presenter for post parameters:, (*18)
```php, (*19)
public function PostNameAttribute($value, $original)
{
return ucfirst($value);
}, (*20)
Add presenter for query string parameters:
```php
public function QuerySaveAttribute($value, $original)
{
return $value === true ? 1 : 0;
}
Add presenter for json raw data parameters:, (*21)
```php, (*22)
public function JsonSaveAttribute($value, $original)
{
return ucfirst($name);
}
````, (*23)
