how to solve undefind variable in laravel

问题

It seems like you're encountering an "Undefined variable $expiredMaterials" error. To fix this, make sure you have defined and passed the variable $expiredMaterials in your controller. In your MaterielsController, you already have the code to retrieve and pass it to the view:

  1. public function index()
  2. {
  3.     $expiredMaterials = Matériels::expired()->get();
  4.     return view('materiels_expires', compact('expiredMaterials'));
  5. }

Ensure that the Matériels model is correctly defined and that the expired() scope is working as expected. If you're still experiencing issues, please double-check your model and scope implementation.

Undefined variable $expiredMaterials (View: C:\Users\Fatima\Desktop\PFE\Gpi_projet\resources\views\materiels_expires.blade.php

here is my code :

  1. 			@foreach($expiredMaterials as $material)
  2. 			<tr>
  3. 				<td class="id">{{ $material->id }}</td>
  4. 				<td class="type">{{ $material->type }}</td>
  5. 				<td class="série">{{ $material->série }}</td>
  6. 				<td class="marque">{{ $material->marque }}</td>
  7. 				<td class="réfference">{{ $material->réfference }}</td>
  8. 				<td class="service">{{ $material->service }}</td>
  9. 				<td class="date">{{ $material->date->format('Y-m-d H:i:s') }}</td>
  10. 				<td class="date">{{ $material->expires_at->format('Y-m-d H:i:s') }}</td>
  11. 				<td class="status">{{ $material->status }}</td>
  12. 				<td class=" text-center">
  13. 					<a class="m-r-15 text-muted update" data-toggle="modal" data-id="'.$value->id.'" data-target="#update">
  14. 						<i class="fa fa-edit" style="color: #2196f3"></i>
  15. 					</a>
  16. 					<a href="{{ url('form/delete'.$value->id) }}" onclick="return confirm('Voulez-vous le supprimé?')">

  18. 					</a>
  19. 				</td>
  20. 			</tr>
  21. 			@endforeach

and this is my controller

  1. <?php
  3. namespace App\Http\Controllers;
  4. use App\Models\Matériels;
  5. use Illuminate\Http\Request;
  6. use Auth;
  7. use DB;

  10. {
  11.    
  13.     public function index()
  14. {
  15.     $expiredMaterials = Matériels::expired()->get();
  16.     return view('materiels_expires', compact('expiredMaterials'));
  17. }
  20.     public function report(Request $request)
  21.     {
  22.         if (Auth::guest()) {
  23.             return redirect()->route('/');
  24.         }
  25.     
  26.         $fromdate = $request->fromdate;
  27.         $todate = $request->todate;
  28.         $name = $request->name;
  29.     
  30.         $data = DB::table('Matériels')
  31.             ->where('date', '>=', $fromdate . ' 00:00:00')
  32.             ->where('date', '<=', $todate . ' 23:59:59')
  33.             ->where('série', 'like', '%' . $name . '%')

  35.             ->get();
  36.     
  37.         $latestEntry = Matériels::latest()->first();
  38.     
  39.         return view('materiels_expires', compact('data', 'latestEntry'));
  40.     }
  41. }

another controller

  33.         return view('report.report', compact('data', 'latestEntry'));
  34.     }
  35.     
  36. }

my model

  1. <?php

  5. use Illuminate\Support\Carbon;
  6. use Illuminate\Database\Eloquent\Factories\HasFactory;
  7. use Illuminate\Database\Eloquent\Model;

  37.         });
  38.     
  39.         static::updating(function ($model) {
  40.             if ($model->expire->isPast()) {
  41.                 $model->status = 'expiré';
  42.                 $model->save();
  43.             }
  44.         });
  45.     }
  46.     
  47.     
  49.     public function scopeExpired($query)
  50.     {
  51.         return $query->whereNotNull('expires_at')
  52.                      ->where('expires_at', '<=', now())
  53.                      ->where('status', '=', 'expiré');
  54.     }
  55. }

Variables must be passed to the view like this:

  1. return view('view', ['variableName' => 'variableValue']);

So in your case, you will need to write your return like so:

  1. return view('materiels_expires', ['expiredMaterials' => compact('expiredMaterials')]);

Then you should be able to access $expiredMaterials in your view.
