How to solve the "Undefined variable" error in Laravel?

Question

I am using Laravel, and I got an error:

Undefined variable: getFormTest (View: C:\xampp\htdocs\survey\resources\views\tambahformtest.blade.php)

That error references to this view:

<input value="{{ $getFormTest[0]->ms_test }}">

I have put $getFormTest in my controller:

public function TambahFormTest()
{
    $ms_id = FormTest::max('ms_id');
    $getFormTest = FormTest::Select('ms_test')->where('ms_id', '=', $ms_id)->get();

    return view('tambahformtest', $getFormTest);
}

The Select probably returns nothing which makes the 0 index invalid/undefined — RST, Nov 07 '16 at 15:04

`return("view.blade")->with(["getFormTest" => $getFormTest]);`: This will allow you to access `{{ $getFormTest }}` in the view. — Tim Lewis, Nov 07 '16 at 15:07

When returning a view in laravel, you have to pass an array of params.

return view ('myView', ['param1' => $v1, 'param2', $v2]);

then in your view

@if(isset($param1) 
   {{ $params->property }}
@endif

You should take a use of compact method of php

public function TambahFormTest()
{
    $ms_id = FormTest::max('ms_id');
    $getFormTest = FormTest::Select('ms_test')->where('ms_id', '=', $ms_id)->get();

    return view('tambahformtest', compact('getFormTest'));
}

This would be sent to view as - ['getFormTest' => $getFormTest]

Hope this helps
