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.

Requirements

PHP 5.6, 7.0+ Laravel 5.3 (LTS) or Laravel 5.4 (Current)

Get Started

Firstly, we install package:

$ composer require atayahmet/laravel-castable

and then we need add the service provider to the app.php

Castable\CastableServiceProvider::class

OK, we done.

Let's see how to use the laravel-castable.

Castable types

Types
string
integer
boolean
float
double
real
unset
array
object (stdClass)
collection

Create Castable Form Request class

We created new artisan command that inspired make:request from laravel built in command.

$ php artisan make:cast ContactRequest

New form of the form request class:

<?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.

Raw and converted type of the attributes

Post:

Name	Value	Type	Cast Type
name	Ali	string	string
age	19	string	integer
student	true	string	boolean
interests	books, computers	array	collection

Query String:

Name	Value	Type	Cast Type
save	true	string	boolean

To get the above result for:

<?php

ContactController extends Controller {

  public index(ContactRequest $contactRequest)
  {
      $contactRequest->cast()->input();
  }
}

Get a input:

$contactRequest->cast()->input('interests'); // collection

$contactRequest->cast()->input('student') // boolean (true)

$contactRequest->cast()->input('save') // boolean (true)

if request is post raw data:

$contactRequest->cast()->json();

$contactRequest->cast()->json('age');

Get original inputs:

$contactRequest->input();

Get original an input:

$contactRequest->input('student'); // string (true)

Original raw data:

$contactRequest->json();

Add presenter to the inputs

You can add presenter to the all post, query and json inputs. This feature gives you a chance to filter inputs.

Add presenter for post parameters:

public function PostNameAttribute($value, $original)
{
    return ucfirst($value);
}

Add presenter for query string parameters:

public function QuerySaveAttribute($value, $original)
{
    return $value === true ? 1 : 0;
}

Add presenter for json raw data parameters:

public function JsonSaveAttribute($value, $original)
{
    return ucfirst($name);
}
