Merge Multiple Collection Paginate in Laravel

If you are merge multiple laravel collection and you need to paginate with laravel collection then i will show you how to paginate a merged collection in laravel 5.8 application. you can easily make pagination of multiple merge collection in laravel 5, laravel 6, laravel 7, laravel 8, laravel 9 and laravel 10.

We will create 'paginate' function using Collection macro method. You need to register that method to AppServiceProvider. i will give you very simple example to understand how it is working for laravel paginate collection or array.

So, basically you can make manually pagination with laravel collection. let's see bellow example:

web/routes.php

Route::get('collection-array', function(){
	$user = \App\User::get();
	$product = \App\Product::get();
    
	$data = $user->merge($product)->paginate(10);
    
	dd($data);
});

Now you need to register collection paginate method on AppServiceProvider file.

app/Providers/AppServiceProvider.php

<?php
    
namespace App\Providers;
   
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Collection;
use Illuminate\Pagination\LengthAwarePaginator;
    
class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        /**
         * Paginate a standard Laravel Collection.
         *
         * @param int $perPage
         * @param int $total
         * @param int $page
         * @param string $pageName
         * @return array
         */
        Collection::macro('paginate', function($perPage, $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,
                ]
            );
        });
    }
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
             
    }
}

Now you can check it...

I hope it can work...
