Laravel - passing variable from controller to view - undefined variable

Question

i'm new to Laravel, but I've been working at it. I've searched the site but can't find specific help. I've created a variable in my Controller (and checked it a 1000 times against a tutorial) and passed it to the view, but the browser gives an error "Undefined variable".

$company holds the table row after posting. I suspect it may have something to do with it being an array.

Controller resource function show

public function show($comp_id)
{
    $company = Company::find($comp_id);
    return view('companies.show')->with('company', $company);   
}

And in the view:

@section('content')
    <h1>{{ $company->CompanyName }}</h1>

I'm sure it's a simple error, but any help please?

Check if dd($comp_id) in the controller return the right value — Diego Cespedes

As mentioned by Sanzeeb, your syntax has several errors. Let's try fixing those first.

In your controller please modify your method like so:

public function show($comp_id)
{
    $company = Company::find($comp_id);

    return view('companies.show')->with('company', $company);
}

Then please modify your fiew like so:

@section('content')

<h1>{{ $company->CompanyName }}</h1>

And let's see if that helps.

Eitan, your quote of my code shows a semi-colon between the variable and the class, but in my submission it did have an equal sign. Your bracketing in the 'return view' is different from what Tom Kopah suggested. I tested both, but still get: ErrorException in 67ad97908c79b9baf76653c370849a03da33d1aa.php line 5: Undefined variable: company (View: C:\Sites\AI\resources\views\companies\show.blade.php)

Sorry gents, this is my first question on SO so I'm still learning the syntaxes and protocol. It seems @Pauwelyn made some errors in transcribing my code from the images I posted in my question. There is a bracket at the end of the return view line and I do have a @stop at the end of my View code.

You need to fix some things. try this please.

In your controller please modify your method like so:

public function show($comp_id)
{
    $company = Company::find($comp_id);

    return view('companies.show', compact('company'));
}

And in the view:

@section('content')
<h1>{{ $company->CompanyName }}</h1>
@stop

I believe this is syntax for Laravel 5, while PDevH's question implies he uses Laracel 4.

@ТомицаКораћ well, in that case lets wait for him to tell us. and if so, Then we will change :)

I'm using Laravel 5.3. I've tested all variations of your suggestions, specifically the bracketing and use of compact vs with. No luck.

Did you added 'use App\Company;` to the namespace?

Turns out I had to set the show($id) to the specific id name in my table column.
public function show($id) $company = Company::where('Comp_id', $id)->first(); return view('companies.show')->withCompany($company);
Thanks for your help anyways.
