"Undefined variable: users" when trying to use @foreach

Question

I am trying to make foreach loop in laravel to list all users but when I use the code that laravel suggested I get this error:

Undefined variable: users (View: /home/vagrant/Code/SimFly/resources/views/profile.blade.php)

The code causing the error is:

@foreach ($users as $user)
<p>This is user {{ $user->id }}</p>
@endforeach

Please can someone help me.

That error message is crystal clear. `$users` is not defined in that scope. How do you think _we_ can help with that? — arkascha, Sep 16 '16 at 15:16

To use users variable in a view you need to pass it from a controller first:

$users = User::all();
return view('profile', compact('users'));

Its also a great practice to check state (isset, count for example) of the array/variable before looping through it, to protect any unforeseen errors.

As per the suggestions above, the problem is that the view was not being passed the variable.

To catch this in the blade template use something like a @forelse instead of a @foreach

ProfileController

$users = User::all();
return view('profile', [
    'users' => $users
]);

Profile Blade

@forelse
    <p>This is user {{ $user->id }}</p>
@empty
    <p>There are no users</p>
@endforelse
