将参数传递给 crud controller 背包 laravel

Question

i create button in the line of the table "league" and when press on it most moved to the table "game" and pass parameter "league_id" to GameCrudController... then when i get the "league_id" in setup function on GameCrudController i have problem, to find the problem i make error_log on setup function to know what happen, i well set the code and some image to show the problem:

added button in the table "league":

$this->crud->addButtonFromView("line", "Games", "games" ,'end');

show button in view league table

create games.blade.php view in vendor\backpack\crud\src\resources\views\crud\buttons\games.blade.php, and the content is:

@if ($crud->hasAccess('games'))
        <a href='{{ backpack_url('game/' . $entry->getKey()) }}' class="btn btn-sm btn-link"><i class="fa fa-edit"></i>Games</a>
@endif

added in the route:

Route::crud('game/{league_id?}', 'GameCrudController');

and in the setup function on GameCrudController:

public function setup()
{
    $this->crud->setModel('App\Models\Game');
    $this->crud->setRoute(config('backpack.base.route_prefix') . '/game');
    $this->crud->setEntityNameStrings('game', 'games');


    $passed_league_id = \Route::current()->parameter('league_id');
    error_log("test");
    error_log($passed_league_id);
}

and in console its access one time to "league_id" and then show empty line after "test" like this:

test
3
.
.
.
test
"empty line"
.
.
.
test
"empty line"
.
.
.

i don't andurstand why print "test" three times and i can't access the passed_id?!

Please help. I want to reach for "league_id" to make filter at GameCrudController. What is the problem in the previous steps and thanks for the help.

What you're seeing is normal. backpack for Laravel uses ajax to get the data later on.

at the first request: your URL looks like this:

/admin/game/1

where 1 is league_id .

after the first request backpack calls ajax requests to show the data. and looks like it's calling

/admin/game/search

instead of

/admin/game/1/search

to repair that you should use setRoute correctly:

$passed_league_id = \Route::current()->parameter('league_id');
if($passed_league_id != null )
{
    $this->crud->setRoute(config('backpack.base.route_prefix') . '/game/'.$passed_league_id);
}
else 
{
    $this->crud->setRoute(config('backpack.base.route_prefix') . '/game');
}

this way it'll generate the routes correctly and all of you're following ajax requests will be made on the base url

/admin/game/1
