Understanding controller methods is essential for backend web development with Laravel. It is a core skill for building maintainable and organized web applications.

1

Create the BookController class

Create a PHP class named BookController inside the namespace App\Http\Controllers that extends the base Controller class.

Laravel

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;

// Your code here

Need a hint?

Remember to declare the namespace and extend the Controller class.

2

Add the index method

Inside the BookController class, add a public method named index that returns the view books.index using return view('books.index');.

Laravel

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;

class BookController extends Controller
{
    // Add the index method here
}

Need a hint?

The index method should be public and return the view books.index.

3

Add the show method with parameter

Inside the BookController class, add a public method named show that accepts a parameter $id and returns the view books.show passing the $id as data using return view('books.show', ['id' => $id]);.

Laravel

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;

class BookController extends Controller
{
    public function index()
    {
        return view('books.index');
    }

    // Add the show method here
}

Need a hint?

The show method should accept $id and pass it to the view books.show.

4

Complete the controller with both methods

Ensure the BookController class contains both the index and show methods exactly as specified, with correct namespace and class declaration.

Laravel

 $id]);
    }

    // Finalize the controller
}

Need a hint?

Check that both methods are present and the class is correctly declared.
