php – Laravel Request input() or get()

Posted by: admin April 23, 2020 Leave a comment

Questions:

With Laravel 5 it seems like method injection for the Request object is preferred over using the Request facade.

<?php namespace App\Http\Controllers;

use Illuminate\Http\Request;

class HomeController extends Controller
{
    public function index(Request $request)
    {
        $email = $request->input('email');

        // OR

        $email = $request->get('email');
    }
}

A few questions I have:

Is using Illuminate\Http\Request better than using Illuminate\Support\Facades\Request

I have no idea how $request->get() is resolving as there is no function name get() in Illuminate\Http\Request. input() and get() does the same thing.

Is method injection better than using Facades?

How to&Answers:

In controller method Request injection functionality is always preferable, because in some methods it could help you to use Form Requests (they are extending default Request class) validation, that will validate your request automatically just before entering to the actual controller method. This is an awesome feature that helps to create slim and clean controller’s code.

Using default Request injection makes your controller’s methods similar and easier to maintain.

Also object injection is always better than Facades, because such methods & objects are easier to test.

get() andinput() are methods of different classes. First one is method of Symfony HttpFoundation Request, input() is a method of the Laravel Request class that is extending Symfony Request class.
