Laravel too few arguments to function,0 passed andexactly 2 expected - php

Question

I am trying to pass the 2 parameters to my index method in the controller but it does not pass and says 0 have been sent. I have checked if the variables can be shown on the view which it can so that isn't the problem.
In my blade file I have the following <a tag:
Is the circumstance: <strong>{{$variables->circumstance}}</strong> true?
web.php route:
Route::resource('attack', AttackController::class)->middleware('auth');
Controller:
public function index($debate, $argument){//}
Error message:
Too few arguments to function App\Http\Controllers\AttackController::index(), 0 passed in C:\Users\hakar\argupedia\Argupedia\vendor\laravel\framework\src\Illuminate\Routing\Controller.php on line 54 and exactly 2 expected

Answer 1

Blade File
Is the circumstance: <strong>{{$variables->circumstance}}</strong> true?
Route File
Route::group(['middleware' => 'auth'], function () {
Route::get('/attack/{debate}/{argument}', 'AttackController#schemes')->name('search');
});
Controller
public function schemes($debate, $argument){
dd($debate, $argument);
}

Answer 2

If you're only using one method in a controller, there is no need for a resource route, Better way would be to create a single route like this:
Route::get('attack/{debate}/{argument}', 'AttackController#index')->middleware('auth')->name('attack.index');
The arguments in the curly brackets are called route parameters. Now, in order to pass this parameters, you need to pass them like key => value arrays
Is the circumstance: <strong>{{$variables->circumstance}}</strong> true?
Now, you have access to these parameters in your controller:
public function index($debate, $argument){
dd($debate, $argument);
}
If both parameters are not required here, you can use optional parameters in your routes, by using ? mark, like this:
Route::get('attack/{debate?}/{argument?}', 'AttackController#index')->middleware('auth');
You can now pass only one parameter to your route, without crashing your application.
