When doing two queries and a merge in Laravel 8, it doesn't sort by expiration date if i use sortBy or sortByDesc

Question

I have made 2 queries to two different tables with with(), and then I have joined them with a merge. But I also want them to be displayed in order of expiration date.

As I have done the orderBy, it is not working for me. what will i be doing wrong? I would appreciate any help. Thank you and sorry for my english:(

Controller:

    public function listado_pendientes(Request $request)
  {
    $incio = Carbon::parse($request->fecha_inicio);
    $fin = Carbon::parse($request->fecha_fin);

    $datecheck =  $incio > $fin ? $fin : $incio;
    
    $dateStart = $datecheck && $datecheck < now() ? $datecheck : now();   
    $dateEnd = $fin && $fin < now() ? $fin : now();   

    // cargo relación de cobros con clientes según las fechas buscadas
    $cobros = Cobro::with('Contrato')
      ->whereBetween('vencimientos', [$dateStart,$dateEnd])     
      ->get();

    // cargo relación de facturas con clientes, según fechas buscadas y que no hayan sido cobradas
    $facturas = Factura::with('Contrato')
      ->whereBetween('vencimientos', [$dateStart,$dateEnd])
      ->where('cobrado', '=', NULL)      
      ->get();
    //dd($cobros);              
    $data = []; 
    $data = $cobros->merge($facturas);
    
    $data = collect($data)->sortByDesc('vencimientos');       

    return Voyager::view('voyager::custom.listado_pendientes', compact('data', 'dateStart','dateEnd'));
  }

Answer 1

You can use the method of PHP multisort for DESC or ASC sorting, it is for sorting multiple or multi-dimensional arrays:

  $array_multisort(array_map('strtotime',array_column($array,'vencimientos')),SORT_DESC,$array);

Answer 2

I found the problem. It is that I am using datatable, which was ordering the table, I have fixed it and now it works with a simple sortByDesc('vencimientos'). I leave the code of the datatable that I have changed. I add the 'bSort'=> false

 array_merge(
                [   
                    'bSort' => false,                   
                    'paging' => false,
                    'language' => __('voyager::datatable'),                    
                    'columnDefs' => [['targets' => 'dt-not-orderable', 'searchable' => false, 'orderable' => false]],
                ],

Answer 3

When you sort collection by keys it will have structure like this:

[
  "0": [COLLECTION],
  "1": [COLLECTION],
  "2": [COLLECTION],
  "3": [COLLECTION],
  ...
]

So, when you return this it will be sorted by keys. You have to get values of that collections.

So, in your case you have to add ->values() method:

$data = collect($data)->sortByDesc('vencimientos')->values();       

Or if it doesn't work try this:

$data = collect($data)->sort(function ($a, $b) {
  return strtotime($a->vencimientos) < strtotime($b->vencimientos);
})
->values();
