Data transfer from controller to blade view
I am trying to send parameters via href to a page from event list to event page.
My route
Route::get('eventpage', 'EventController@index')->name('eventpage');
And my event controller
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
class EventController extends Controller
{
public function index(Request $request)
{
$id = $request->query('id');
$event = DB::table('events')->where('id',$id)->get();
$pics = DB::table('pictures')->where('event_id',$id)->get();
$n = count($pics); // the number of pictures for a particular event
return view('pages.eventPage');
}
}
The problem is that for the first variable I try to use, $ n, it gives me an error, "Undefined variable: n"
My left code looks like this
@for($i = 1; $i < $n; $i++)
<li data-target="#carousel-example-generic" data-slide-to="{{ $i }}"></li>
@endfor
What am I doing wrong?

$pics = DB::table('pictures')->where('event_id',$id)->get();
return view('pages.eventPage',compact('event','pics'));
}
}
blade code
@for($i = 1; $i < count($pics); $i++)
<li data-target="#carousel-example-generic" data-slide-to="{{ $i }}"></li>
