💡 Why This Matters

🌍 Real World

Accessing request data is essential for handling user input in web applications, such as forms, API calls, and user interactions.

💼 Career

Understanding how to retrieve and use request data is a fundamental skill for backend developers working with Laravel or similar frameworks.

1

Create a controller method with a Request parameter

Create a public method called store inside a controller class named UserController. The method should accept a parameter named $request of type Illuminate\Http\Request.

Laravel

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class UserController extends Controller
{
    // Create the store method with Request parameter here
}

Need a hint?

Remember to import the Request class and define the method inside the controller class.

2

Add a helper variable for the input key

Inside the store method, create a variable called $inputKey and set it to the string 'username'.

Laravel

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class UserController extends Controller
{
    public function store(Request $request)
    {
        // Create $inputKey variable here
    }
}

Need a hint?

Use a simple assignment statement to create the variable.

3

Access the input data from the request

Inside the store method, use the $request object and the input method with the variable $inputKey to get the user input. Store this value in a variable called $username.

Laravel

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class UserController extends Controller
{
    public function store(Request $request)
    {
        $inputKey = 'username';
        // Get the username from the request input
    }
}

Need a hint?

Use the input method on the $request object with the key variable.

4

Return a response with the accessed username

Inside the store method, return a response using the response() helper that returns the string 'Username: ' concatenated with the $username variable.

Laravel

input($inputKey);
        // Return a response with the username
    }
}

Need a hint?

Use the response() helper function to return a string response.
