Foreach doesnt work in my View in laravel 5.6 - laravel

Question

public function getValues(Request $request){
$typ=$request->get('typ');
$stellentyp=$request->get('stellentyp');
$bereich=$request->get('bereich');
$abschluss=$request->get('abschluss');
$user = DB::table('users')->get();
$angebots = DB::table('angebots') ->orderBy('stellenname', 'asc');
if(!empty($request->get('stellentyp'))){
$angebots->where('stellentyp', $stellentyp);
}
$angebots->get();
$row = $angebots->count();
return view('user/angebots', compact('typ', 'stellentyp', 'bereich', 'abschluss', 'row', 'angebots', 'user'));
}
this is my controller
{{$row}} Angebote insgesamt
<div class="row">
#foreach ($angebots as $angebot)
<div class="col-12 col-md-6 col-lg-4 pt-4">
<div class="card offer-card">
<div class="card-image">
<img class="img-fluid" src="{{ asset('uploads/avatars/' . $user[$angebot->firma -1]->avatar) }}">
</div>
<div class="card-body">
<h4 class="text-j4y-dark praktikumstitel">{{ $angebot->stellenname }}</h4>
Jetzt mehr anzeigen »
</div>
</div>
</div>
#endforeach
</div>
and this is my view
but i got this error message:
Undefined property: Illuminate\Database\MySqlConnection::$firma (View: C:\wamp\sites\j4ylara\resources\views\user\angebots.blade.php)
if I put the get behind my first statement so like this
$angebots = DB::table('angebots') ->orderBy('stellenname', 'asc')->get();
but then the filter doesn't work
I don't know how I can view my results
I only know this way
{{$angebot[1]->stellenname}}
but I want all my results so I use a foreach but it doesn't work
does anyone know why?

Answer 1

In the following snippet
$angebots = DB::table('angebots') ->orderBy('stellenname', 'asc');
if(!empty($request->get('stellentyp'))){
$angebots->where('stellentyp', $stellentyp);
}
$angebots->get();
You're doing $angebots->get() which returns the results of your query. You need to assign the results of your query to a variable and pass that into your view. You could do something like this:
$angebots = $angebots->get();
Which would assign the result of the query to $angebots and then you could use it in your view.
Personally, I would consider renaming $angebots to $angebotsQuery or something similar and then do this:
$angebotsQuery = DB::table('angebots') ->orderBy('stellenname', 'asc');
if(! empty($request->get('stellentyp'))){
$angebotsQuery->where('stellentyp', $stellentyp);
}
$angebots = $angebotsQuery->get();

Answer 2

You are sending the Builder in $angebot. Try putting the results in a variable.
public function getValues(Request $request){
$typ=$request->get('typ');
$stellentyp=$request->get('stellentyp');
$bereich=$request->get('bereich');
$abschluss=$request->get('abschluss');
$user = DB::table('users')->get();
$angebots = DB::table('angebots') ->orderBy('stellenname', 'asc');
if(!empty($request->get('stellentyp'))){
$angebots->where('stellentyp', $stellentyp);
}
$angebots = $angebots->get();
$row = $angebots->count(); //this will not cause an issue since the Collection has a count method
return view('user/angebots', compact('typ', 'stellentyp', 'bereich', 'abschluss', 'row', 'angebots', 'user'));
}
