Laravel 5 Blade模板未定义变量

Question

I did a search and I want to display the result, but I cannot convey the variable to the view, although I specify it in the controller.

My piece of view code:

<div class="search col-md-6">
    <p>
        Найти сотрудника по id
    </p>
    <form action="{{route('searchID')}}" class="search-id" method="GET">
        <div class="row">
            <div class="col-xs-10">
                <div class="form-group">
                    <input class="form-control" name="id" required="" type="text" value="{{ old('id') }}">
                    </input>
                </div>
            </div>
            <div class="col-xs-2">
                <div class="form-group">
                    <input class="btn btn-info" type="submit" value="Искать">
                    </input>
                </div>
            </div>
        </div>
        {{$result}}
    </form>
    <div>
    </div>
</div>

my route:

 Route::match(['get', 'post'], 'searchID', 'SearchController@indexID')->name('searchID');

my method in the controller:

public function indexID(Request $request, View $view)
{
    //$message= "Сотрудник не найден";
    $id = $request->input('id');
    dump($id);
    $result = Staff::where('public_id', $id)->get();

    if ($result == null) {
        //dump($message);
        return redirect()->back()->withInput($id);
    } else {
        dump($result);
        return view('addworker')->with('result', $result);
    }
}

But I constantly get an error: Undefined variable: result

I tried:

return view('addworker')->with($result);

and

return view('addworker',$result);

and

return view('addworker', ['result', $result]);

None of this helped me, I don't know what to do anymore

How to make the template access this variable only after the controller has been processed?

Answer 1

You can use compact for the same,

return view('addworker', compact('result'));

compact — Create array containing variables and their values

Answer 2

我希望这能帮到您

return view('addworker', ['result' => $result]);

Answer 3

You used the wrong syntax to send your variable to your view, there is a lot os ways to do that:

You could use the compact function:

return view('addworker', compact('result'));

You could use the with() method:

return view('addworker')->with('result', $result);

Or:

return view('addworker', ['result' => $result]);
