如何在laravel 8中预先选择多个选项

namespace App\Http\Controllers;

use App\Models\User;
use Illuminate\Http\Request;

class UserController extends Controller
{
    public function edit(User $user)
    {
        // 假设我们有一个角色列表
        $roles = ['admin', 'editor', 'viewer'];

        // 获取当前用户的角色
        $userRoles = $user->roles()->pluck('name')->toArray();

        return view('users.edit', compact('user', 'roles', 'userRoles'));
    }

    public function update(Request $request, User $user)
    {
        // 更新用户逻辑
    }
}

<!-- resources/views/users/edit.blade.php -->
<form action="{{ route('users.update', $user) }}" method="POST">
    @csrf
    @method('PUT')

    <label for="roles">Roles:</label>
    @foreach ($roles as $role)
        <div>
            <input type="checkbox" id="role-{{ $role }}" name="roles[]" value="{{ $role }}" {{ in_array($role, $userRoles) ? 'checked' : '' }}>
            <label for="role-{{ $role }}">{{ $role }}</label>
        </div>
    @endforeach

    <button type="submit">Update</button>
</form>
