Controller

• stored in the app/Http/Controllers directory
• Instead of defining all of request handling logic in the web.php file, for larger projects, it is encouraged to organize using "controller" classes
• Controllers can group related request handling logic into a single class

Create a simple controller

• php artisan make:controller HomeController
• a HomeController file is created at app/Http/Controllers folder, open it and edit the following

class HomeController extends Controller{
	public function home(){		//home method of the HomeController class
		return view('home.index');
	}
	public function contact(){	//contact method of the HomeController class
		return view('home.contact');
	}
}

• go to web.php file and change the following

use App\Http\Controllers\HomeController;
Route::get('/',[HomeController::class, 'home']);
Route::get('/contact',[HomeController::class, 'contact']);

Create a resource controller

• a resource controller has CRUD actions already defined (Create, Read, Update, Delete)

php artisan make:controller PostController --resource	//--resource will generate CRUD action automatically

• a PostController file is created at app/Http/Controllers folder, open it and edit the following

use App\Models\BlogPost;

class PostController extends Controller{
	public function index(){ 
		$posts = BlogPost::all();
        return view('posts.index',['posts' => $posts]);
	}
	public function show($id){
		$post = BlogPost::find($id);
        return view('posts.show',['post' => $post]);	
	}
	public function create(){}
	public function store(Request $request){}
	public function edit($id){}
	public function update(Request $request, $id){}
	public function destroy($id){}
}

• go to web.php file and change the following

use App\Http\Controllers\PostController;

Route::resource('posts',PostController::class);							//for all actions
Route::resource('posts',PostController::class)->only(['index','show']);	//or we can limit to only certain actions needed
