Filter, sort, and paginate in Laravel in 10 simple lines

Laravel is a very popular PHP framework that makes it easy to create web applications. One of its most useful features is the ability to handle large volumes of data efficiently. In this article, we will explore how to filter, sort, and paginate data in Laravel using a simple and straightforward approach in just ten lines of code.

Introduction to Filtering and Sorting in Laravel

When working with collections of data in Laravel, it may be necessary to implement them to enhance the user experience. Often, data needs to be filtered and sorted according to specific criteria, and paginated to prevent too many items from being displayed in a single view. Below, we describe how to perform these essential tasks in Laravel.

How to Filter and Sort Data?

To start, it’s important to define what information you want to display and how you want the user to interact with it. Laravel provides built-in methods that make executing these processes easy. For example, you can query to get all the data from a table and then apply filters based on input parameters.

$users = User::query()
    ->when(request('search'), function ($query) {
        return $query->where('name', 'like', '%' . request('search') . '%');
    })
    ->orderBy(request('sort', 'created_at'), 'desc')
    ->paginate(10);

In this code snippet, when is used for filtering based on a search, and orderBy is for sorting the results. Additionally, paginate is implemented to break the list into more manageable pages.

Implementing Pagination

Pagination in Laravel is extremely easy to implement. By using the paginate method, you can set how many items you want to display on each page. In the example above, it is configured to show 10 users per page. As users navigate between pages, Laravel will automatically generate the necessary links to facilitate navigation.

Moreover, Laravel allows you to customize the number of items per page through user input if desired. You could incorporate a slider or a dropdown where the user can choose how many items they would like to see.

Complete Example

Here is how to integrate everything in a Laravel controller:

public function index()
{
    $users = User::query()
        ->when(request('search'), function ($query) {
            return $query->where('name', 'like', '%' . request('search') . '%');
        })
        ->orderBy(request('sort', 'created_at'), 'desc')
        ->paginate(10);

    return view('users.index', compact('users'));
}

The index method of this controller searches for users and applies the relevant filters and sorting, returning the corresponding view along with the paginated collection of users.

Advantages of Using Laravel for Filtering, Sorting, and Pagination

Using Laravel for data management offers a robust and efficient solution. Its clear syntax and integrated SQL query implementation allow developers to focus on application logic without getting bogged down by technical details.

Additionally, as a widely adopted framework, Laravel has a large community that provides support and case examples. This further facilitates learning and implementing advanced data handling techniques.

Conclusion

Filtering, sorting, and paginating data in Laravel is a simple and straightforward process that can significantly enhance the user experience in your web application. With the tools that Laravel offers, you can manage large volumes of data effectively and professionally.
