Laravel变量不通过

Question

I'm an absolute beginner and I'm trying to do a CRUD in Laravel, but I can not figure it out why my variables aren't being passed over to the view so I can have a dynamic display of them in the table.

My "routes" work fine.

Then my controller

     public function getHome()
     {

     $results = Crud::index();
     return view('pages/home', ['results' => $results]);

     }

Calls my "Crud" model

class Crud extends Model
{
     public static function index()
     {

        return $results = DB::table('data')
                         ->whereNotNull('id')
                          ->get();
     }
}

And goes to my view as seen in the controller

@extends('main')

@section('title', '| Home')

@section('content')

 <div class="container">

     @include ('partials/_jumbotron')

     <table class="table table-inverse">
   <thead>
    <tr>
      <th>#</th>
      <th>First Name</th>
      <th>Last Name</th>
      <th>Username</th>
    </tr>
 </thead>
 <tbody>


 @if(!empty($results))

  @foreach($results as $result)

  <tr>
    <td scope="row">$result->$id</th>
    <td>$result->$first_name</td>
    <td>$result->$last_name</td>
    <td>$result->$username</td>
  </tr>

@endforeach

 @endif

</tbody>
</table>
</div>

 @endsection

Thanks for the help in advance...I'm losing my mind And sorry If I wasn't specific enough..

Edit1: I did as you say, but I'm still not outputing data to my table? Is there anything else wrong in the stated code or is the bug somewhere deeper?

Edit2: Thanks everyone for the pointed out mistakes - blade {{ }} and object properties $object->propertie not $object->$propertie

When I fixed those mistakes which were obviously denying the output I remembered that I have an empty database.. Case Closed - Thanks everyone for the help

Answer 1

You're not printing the variables. You're printing literals.

If you want to print the variables (echo them) in blade files, you need to wrap them in curly brackets. Also there's not $ when you want to display an object attribute. Like that:

@foreach($results as $result)

<tr>
    <td scope="row">{{ $result->id }}</th>
    <td>{{ $result->first_name }}</td>
    <td>{{ $result->last_name }}</td>
    <td>{{ $result->username }}</td>
</tr>

@endforeach
