Configuration

In other frameworks, pagination can be very painful. Laravel makes it a breeze. Laravel can generate an intelligent "range" of links based on the current page. The generated HTML is compatible with the Bootstrap CSS framework.

Usage

There are several ways to paginate items. The simplest is by using the paginate method on the query builder or an Eloquent model.

Paginating Database Results

$users = DB::table('users')->paginate(15);

Note: Currently, pagination operations that use a groupBy statement cannot be executed efficiently by Laravel. If you need to use a groupBy with a paginated result set, it is recommended that you query the database manually and use Paginator::make.

Paginating An Eloquent Model

You may also paginate Eloquent models:

$allUsers = User::paginate(15);

$someUsers = User::where('votes', '>', 100)->paginate(15);

The argument passed to the paginate method is the number of items you wish to display per page. Once you have retrieved the results, you may display them on your view, and create the pagination links using the render method:

<div class="container">
	<?php foreach ($users as $user): ?>
		<?php echo $user->name; ?>
	<?php endforeach; ?>
</div>

<?php echo $users->render(); ?>

This is all it takes to create a pagination system! Note that we did not have to inform the framework of the current page. Laravel will determine this for you automatically.

You may also access additional pagination information via the following methods:

• currentPage
• lastPage
• perPage
• total
• count

"Simple Pagination"

If you are only showing "Next" and "Previous" links in your pagination view, you have the option of using the simplePaginate method to perform a more efficient query. This is useful for larger datasets when you do not require the display of exact page numbers on your view:

$someUsers = User::where('votes', '>', 100)->simplePaginate(15);

Creating A Paginator Manually

Sometimes you may wish to create a pagination instance manually, passing it an array of items. You may do so by creating either an Illuminate\Pagination\Paginator or Illuminate\Pagination\LengthAwarePaginator instance, depending on your needs.

Customizing The Paginator URI

You may also customize the URI used by the paginator via the setPath method:

$users = User::paginate();

$users->setPath('custom/url');

The example above will create URLs like the following: http://example.com/custom/url?page=2

Appending To Pagination Links

You can add to the query string of pagination links using the appends method on the Paginator:

<?php echo $users->appends(['sort' => 'votes'])->render(); ?>

This will generate URLs that look something like this:

http://example.com/something?page=2&sort=votes

If you wish to append a "hash fragment" to the paginator's URLs, you may use the fragment method:

<?php echo $users->fragment('foo')->render(); ?>

This method call will generate URLs that look something like this:

http://example.com/something?page=2#foo

Converting To JSON

The Paginator class implements the Illuminate\Contracts\Support\JsonableInterface contract and exposes the toJson method. You may also convert a Paginator instance to JSON by returning it from a route. The JSON'd form of the instance will include some "meta" information such as total, current_page, and last_page. The instance's data will be available via the data key in the JSON array.
