Fine-tuning Pagination Links in Laravel

Laravel's onEachSide method offers granular control over the pagination links displayed near the current page, enhancing navigation clarity. Instead of relying on the default link count, you can tailor the display to suit your application's specific needs.

This is especially beneficial for applications handling datasets of varying sizes. For larger datasets, you might want to show more navigation options; for smaller ones, a cleaner, less cluttered interface is preferable.

Here's how to implement adaptive pagination:

<?php namespace AppHttpControllers;

use AppModelsArticle;
use IlluminateHttpRequest;

class ArticleController extends Controller
{
    public function index(Request $request)
    {
        $perPage = $this->determinePerPage($request);
        $articles = Article::latest()
            ->withCount('comments')
            ->paginate($perPage);
        $linksToShow = $this->calculateVisibleLinks($articles);

        return view('articles.index', compact('articles', 'linksToShow'));
    }

    private function determinePerPage(Request $request): int
    {
        return $request->query('show', 10);
    }

    private function calculateVisibleLinks($paginator): int
    {
        $totalPages = $paginator->lastPage();

        // Dynamically adjust visible links based on total pages
        return match(true) {
            $totalPages > 20 => 3,
            $totalPages > 10 => 2,
            default => 1
        };
    }
}

In your blade template (articles.index.blade.php):

{{ $articles->onEachSide($linksToShow)->links() }}

This results in a dynamic pagination display:

<code>// ~50 articles (5 pages)
« 1 2 3 4 5 »

// ~150 articles (15 pages)
« 1 ... 4 5 6 7 8 ... 15 »

// ~250 articles (25 pages)
« 1 ... 4 5 6 7 8 9 10 ... 25 »</code>

The onEachSide method, combined with dynamic link calculation, creates a more user-friendly and adaptable pagination experience.
