How to Fix Undefined Variable $data Error in Laravel Views?

Undefined variable $data:

But I have declared $data on the controller like this:

public function coba()
{
    $data = coba::all();
    return view('coba');
}

And the view like this

coba.blade.php

@foreach ($data as $w)
    <tr>
        <td>{{$w->name}} </td>
        <td>{{$w->no}}</td>
        <td>{{$w->fraksi}}</td>
        <td>{{$w->dapil}}</td>
    </tr>
@endforeach

What's wrong?

The issue you're encountering is due to the missing variable $data in the return view('coba'); statement of your controller.

To fix this, you need to pass the $data variable to the view so that it is accessible within the blade template.

public function coba()
{
    $data = coba::all();
    return view('coba', ['data' => $data]);
}
