laravel route variables passing null values give url error

I have a route that has 3 optional variables declared as null in Controller

Route::get('gegonota/{gid?}/{cid?}/{nid?}', [
'uses' => 'GegonosController@index', 
'as' => 'gegonota'
]);

and even i change the order of the parameter the problem still exists.

public function index($gid = null, $cid = null, $nid = null)

When values of the variables are null are not showing in the url like 

http://localhost:8000/gegonota///1

and gives me route errors like it didnt find the specific url.

I have to check and substitute null to 0 so that has something in the url and give no error. Which is laravel way to do that avoiding all the trouble. thanks

You may be interested in using Optional Path Parameter as stated in Laravel doc. This means you'll have:

Route::get('gegonota/{gid}/{cid}/{nid?}', [
    'uses' => 'GegonosController@index', 
    'as' => 'gegonota'
]);

Hope this solves the issue.

Update

Even though I cannot say this is the fix since you said rearranging the variable did not solve the issue. I would rather pass those optional variables as request parameters to make things easy, i.e my url would look like:

http://localhost:8000/gegonota/?gid=&cid=&nid=

Therefore, I can already set the default for each of the expected parameters as null rather than deal with inconsistency that may arise from having this kind of wierd /// in my url:

//In a controller
public funtion index()
{
    //put them in an array
    $my_variables = request()->only(['gid', 'cid', 'nid']);

    //or this way
    $gid = request()->get('gid');
    $cid = request()->get('cid');
    $nid = request()->get('nid');

   //they are default to null if not existing or have no value
}

This means your route declaration is simple, i.e:

Route::get('gegonota', [
    'uses' => 'GegonosController@index', 
    'as' => 'gegonota'

])

Unless there is an exceptional need to pass those optional variable to the path, its clearly easier and better to have it as request parameters. Hope this is better.
