PHP Laravel如何按类别排序

Question

I'm building a Laravel application and I have now added two tables, an "employees" and "employees_category" table. Both of them have an "order" column so that I can set the order of how the categories and employees will be displayed on the website.

When I add an employee, I can assign them to a category. So far so good, I'm able to display the employees in order they have been set, but not the categories.

This is what I have so far:

My EmployeesController:

public function index()
{
    $employees = Employee::all()->groupBy('category');

    return view('app.employee.index', compact('employees'));
}

And in my blade view:

@foreach ($employees as $category => $workers)
<div class="col text-center mb-6">
    <h2>{{ $category }}</h2>
</div>
<div class="row px-4 px-xl-10">
    @foreach($workers->sortBy('employee_order') as $worker)
      // some content
    @endforeach
</div>
@endforeach

This sorts the employees correctly by order-number but not the categories, how can I achieve that?

Why dont you query exactly what you want in your view

public function index()
{
    $categories = Category::with('employees')->get();

    return view('app.employee.index', compact('categories'));
}

and in the view : (notice what you want is as $category => $workers )

@foreach ($categories as $category)
<div class="col text-center mb-6">
    <h2>{{ $category }}</h2>
</div>
<div class="row px-4 px-xl-10">
    @foreach($category->employees->sortBy('employee_order') as $worker)
      // some content
    @endforeach
</div>
@endforeach

The good thing is you can now paginate on the catogories
