laravel将参数从url传递到路由和控制器

Question

After button click from JavaScript I redirecting page with

 window.location.href = '//dziennik_zdarzen?id_seo=5';

Next i want pass it to the controller from my route this part is not working

Route::get('dziennik_zdarzen', ['uses'=>'Dziennik_zdarzenController@get_datatable']);

I attempted a lot of things like trying to get it in my controller from url but it didn't work. so im trying to pass it to Dziennik_zdarzenController@get_datatable. I changed my url to something like '//dziennik_zdarzen/5' in windows.location.href and next I tried to pass it in route. Like that:

Route::get('dziennik_zdarzen/{id_seo}', ['uses'=>'Dziennik_zdarzenController@get_datatable']); 

still not working

Here is my controller

<?php
namespace App\Http\Controllers;

use Illuminate\Support\Facades\Input;
use Illuminate\Support\Facades\Route;
use Illuminate\Support\Facades\DB;
use Illuminate\Http\Request;
use Yajra\Datatables\Datatables;
use App\Dziennik_zdarzen;

class Dziennik_zdarzenController extends Controller
{
  public function get_datatable($id_seo)
  {

  return $id_seo;

  }
}
?>

If you can guide me what im doing wrong i will be thankful

Answer 1

You send id_seo as query parametr. You can access it with Request object in controller

<?php
namespace App\Http\Controllers;

use Illuminate\Support\Facades\Input;
use Illuminate\Support\Facades\Route;
use Illuminate\Support\Facades\DB;
use Illuminate\Http\Request;
use Yajra\Datatables\Datatables;
use App\Dziennik_zdarzen;

class Dziennik_zdarzenController extends Controller
{
  public function get_datatable(Request $request)
  {

      return $request->id_seo;

  }
}
?>

If you want send it as route parametr

window.location.href = '//dziennik_zdarzen/5';

Answer 2

In controller:

$idSeo = request('id_seo');

Route:

Route::get('dziennik_zdarzen', 'Dziennik_zdarzenController@get_datatable');

No need for a use statement, dependency injection or a route parameter.
