How do I use multiple variables that are returned by different functions in the controller. Please take a look at the codes to understand what I exactly mean.
Here is the controller:
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use DB;
use App\User;
class HomeController extends Controller
{
public function function1(){
// https://site.com/home
$res = \DB::table("somedb")->get();
return view('home', ["variable1"=>$res]);
}
public function function2($id){
// https://site.com/home/1
$res = \DB::table("somedb")->where("id", $id)->get();
return view('home', ["variable2"=>$res]);
}
}
And here is the home.blade.php
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
<title></title>
</head>
<body>
<table>
<thead>
<tr>
<th>ID</th>
<th>Name</th>
<th>Process</th>
</tr>
</thead>
@if(isset($variable1))
<tbody>
@foreach($variable1 as $row)
<tr>
<td>{{$row->id}}</td>
<td>{{$row->name}}</td>
<td>[a button to edit this row etc..]</td>
</tr>
@endforeach
</tbody>
@else
<tbody>
@foreach($variable2 as $row)
<tr>
<td>{{$row->id}}</td>
<td><input type="text" name="name" value="{{$row->name}}"></td>
<td>[a button to submit etc..]</td>
</tr>
@endforeach
</tbody>
@endif
</table>
</body>
</html>
When I'm trying to this, giving me an error of "Undefined variable: variable2 (View: .../home.blade.php)"
The reason i wanna do this is that i dont wanna create another view.
What should I do
@uhbc if you don't want to create another view, then do not create another function
public function function1($id = null)
{
if($id) {
$result = \DB::table('somedb')->where('id', $id)->get();
} else {
$result \DB::table('somedb')->get();
}
return view('home', ['result' => $result]);
}
Now find a way to do a if statement in the view
@if( count($result) > 1 ) // collection
@else // single record
Typically, you'd have 2 different methods for what you're doing. An index method traditionally returns all results for something, and a show method shows a specific result (like by id). I wouldn't mix those into a single controller/view.
Your controller logic will be simpler, as well as the individual view files since they won't have as much going on in them.
