Passing multiple parameters to controller in Laravel 5

In my application, a user has the ability to remind another user about an event invitation. To do that, I need to pass both the IDs of the event, and of the user to be invited.

In my route file, I have:

Route::get('events/{id}/remind', [
'as' => 'remindHelper', 'uses' => 'EventsController@remindHelper']);


In my view, I have:

{!!link_to_route('remindHelper', 'Remind User', $parameters = array($eventid = $event->id, $userid = $invitee->id) )!!}

In my controller, I have:

public function remindHelper($eventid, $userid)
{
$event = Events::findOrFail($eventid);
$user = User::findOrFail($userid);
$invitees = $this->user->friendsOfMine;
$invited = $event->helpers;
$groups = $this->user->groupOwner()->get();
return view('events.invite_groups', compact('event', 'invitees', 'invited', 'groups'));
}

However, when I hit that route, I receive the following error:

Missing argument 2 for App\Http\Controllers\EventsController::remindHelper()

I'm sure I have a formatting error in my view, but I've been unable to diagnose it. Is there a more efficient way to pass multiple arguments to a controller?

When you define this route:

Route::get('events/{id}/remind', [
'as' => 'remindHelper', 'uses' => 'EventsController@remindHelper']);

You are saying that a single URI argument will be passed to the method.

Try passing the two arguments, like:

Route::get('events/{event}/remind/{user}', [
'as' => 'remindHelper', 'uses' => 'EventsController@remindHelper']);

View:

route('remindHelper',['event'=>$eventId,'user'=>$userId]);

Go to your controller and write code like following:


public function passData()
{

$comboCoder=['Bappy','Sanjid','Rana','Tuhin'];
$ffi=['Faisal','Sanjid','Babul','Quiyum','Tusar','Fahim'];
$classRoom=['Sanjid','Tamanna','Liza'];
return view('hyper.passData',compact('comboCoder','ffi','classRoom'));
}

/*
Again, in View part use:
(passData.blade.php)
*/

<u>Combocoder:</u>

@foreach($comboCoder as $c)
{{$c}}<br>
@endforeach

<u>FFI</u>

@foreach($ffi as $f)

{{$f}}<br>
@endforeach

<u>Class Room </u>

@foreach($classRoom as $cr)

{{$cr}}<br>
@endforeach

Route::get('/details/{id}/{id1}/{id2}', 'HomeController@SearchDetails');

//pass data like the below code

<a href="{{url("/details/{$orga_list->dcode}/{$orga_list->dname}/{$GroupHead}")}}"
target="_blank" > Details </a>

//controller write like the below code

public function SearchDetails($id, $searchtext,$grp_searchtext)
{
// get data like the below code

$data['searchtext'] = $searchtext;
$data['grp_searchtext'] = $grp_searchtext;
$data['id_is'] = $id;
}

**Route** :

Route::get('warden/building/{buildingId}/employee/{employeeId}',[
'uses'=>'WardenController@deleteWarden',
'as'=>'delete-warden'
]);

**View** :

<a href="{{route('delete-warden',[$building->id])}}"></a>

**Controller**:

public function deleteWarden($buildingId,$employeeId){
$building = Building::find($buildingId);
$building->employees()->detach($employeeId);
return redirect('warden/assign/'.$buildingId)->with('message','Warden Detached successfully');

}

This is how you do it:

<a href="{{route('route.name',['param1'=>$variable1,'param2'=>$variable2])}}">Click Here</a>

routes/web.php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\BookController;

Route::controller(BookController::class)->group(function () {
Route::get('author/{author_name}/book/{title}', 'show')
->name('book.show');
});

Now update the controller like:

app/Http/Controllers/BookController.php

namespace App\Http\Controllers;

use App\Models\Book;
use App\Models\Author;
use Illuminate\Http\Request;

class BookController extends Controller
{

public function show(Request $request, Author $author, Book $book)
{
return view('show',[
'book' => $book->show($request)
]);
}
}

Now update the book model:

app\Models\Book.php

namespace App\Models;

use App\Common\HasPdf;
use App\Common\HasImage;
use Illuminate\Contracts\Database\Eloquent\Builder;
use Illuminate\Support\Facades\URL;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\BelongsTo;
use Illuminate\Database\Eloquent\Factories\HasFactory;

class Book extends Model
{
use HasFactory;

protected $guarded = [];

public function author() : BelongsTo
{
return $this->belongsTo(Author::class);
}


public function url()
{
return URL::route('book.show', [
'author_name' => $this->author->author_name,
'title' => $this->title,
]);
}
}

<a href="{{ $item->url() }}"><h3>{{ $item->title }}</h3></a>

Hope it can help you.
