使用compact从控制器传递数组以查看laravel

Question

I'm using laravel 5.3 (make:auth automatic register and user authentication generator), and I would like to let user choose their tags in the registration form.

I wanna pass $tags = App\Tag::all(); to the register.blade.php file located in views\authegister.blade.php.

I found this method:

public function showRegistrationForm()
{
    return view('auth.register');
}

and I would like to do:

public function showRegistrationForm()
{
    $tags = App\Tag::all();
    return view('auth.register', compact($tags));
}

but I get undefined variable 'tags' when trying to reach the register.blade.php file.

Answer 1

Don't feed the variable itself, provide the variable name when using compact.

return view('auth.register', compact('tags'));
