Laravel 7 - Pagination on Collection - laravel

Question

I need to get my data with pagination when I use collection.
Couldn't find any way, and nothing works that written on documents.
Here's my controller;
...
$data = $process->paginate(30);
$data = OrderResource::collection($data);
And here's my resource:
<?php
namespace App\Http\Resources;
use Carbon\Carbon;
use Illuminate\Support\Facades\Auth;
use Illuminate\Http\Resources\Json\JsonResource;
class OrderResource extends JsonResource
{
/**
* Transform the resource into an array.
*
* #param \Illuminate\Http\Request $request
* #return array
*/
public function toArray($request)
{
$user = Auth::user();
return [
"id" => $this->id,
"customer" => $this->customer,
"vehicle" => $this->vehicle,
"basket" => $this->basket,
"total" => money_formatter($this->total),
"discount" => $this->discount,
"net_total" => money_formatter($this->net_total),
"status" => $this->status,
"payment_type" => $this->payment_type,
"main_name" => $this->vehicle->fleet_id ? $this->vehicle->fleet->title : ($this->customer->company_id ? $this->customer->company->title : $this->customer->fullname),
"sub_name" => $this->vehicle->fleet_id ? ($this->customer->company_id ? $this->customer->company->title : $this->customer->fullname) : '',
"created_at" => Carbon::parse($this->created_at)->formatLocalized('%a, %d %B %Y'),
];
}
}

Answer 1

You can add a macro inside your AppServiceProvider.php for this, inside the boot method.
/**
* Paginate a standard Laravel Collection.
*
* #param int $perPage
* #param int $total
* #param int $page
* #param string $pageName
* #return array
*/
Collection::macro('paginate', function ($perPage = 15, $total = null, $page = null, $pageName = 'page') {
$page = $page ?: LengthAwarePaginator::resolveCurrentPage($pageName);
return new LengthAwarePaginator(
$this->forPage($page, $perPage),
$total ?: $this->count(),
$perPage,
$page,
[
'path' => LengthAwarePaginator::resolveCurrentPath(),
'pageName' => $pageName,
]
);
});
And then you can use it like this (assuming $data is a regular laravel collection)
$data = $data->paginate(50);
dd($data);

You can't add any metadata (pagination links) with the collection method. First create a ResourceCollection with php artisan make:resource -c OrderCollection.
Then, in that newly created file, you can do the following.
class OrderCollection extends ResourceCollection
{
/**
* Transform the resource collection into an array.
*
* #param \Illuminate\Http\Request $request
* #return array
*/
public function toArray($request)
{
$collection = [
'data' => OrderResource::collection($this->collection)
];
if ($this->resource instanceof \Illuminate\Pagination\LengthAwarePaginator) {
$collection['pagination'] = [
'current_page' => $this->resource->currentPage(),
'last_page' => $this->resource->lastPage(),
'first_page_url' => $this->resource->url(1),
'last_page_url' => $this->resource->url($this->resource->lastPage()),
'prev_page_url' => $this->resource->previousPageUrl(),
'next_page_url' => $this->resource->nextPageUrl(),
'from' => $this->resource->firstItem(),
'to' => $this->resource->lastItem(),
'total' => $this->resource->total(),
'per_page' => $this->resource->perPage(),
'path' => $this->resource->path(),
];
}
return $collection;
}
}
dd(json_encode(new OrderCollection(Order::paginate(3)), JSON_PRETTY_PRINT));
