Passing multiple parameters to controller in Laravel 5 - php

Question

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?

Answer 1

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]);

Answer 2

Route :
Route::get('warden/building/{buildingId}/employee/{employeeId}',[
'uses'=>'WardenController#deleteWarden',
'as'=>'delete-warden'
]);
View :
Controller:
public function deleteWarden($buildingId,$employeeId){
$building = Building::find($buildingId);
$building->employees()->detach($employeeId);
return redirect('warden/assign/'.$buildingId)->with('message','Warden Detached successfully');
}

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

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,
]);
}
}
<h3>{{ $item->title }}</h3>
Hope it can help you.
