README

This is a simple component for CakePHP 4 which injects pagination information from CakePHP's Paginator into serialized JsonView and XmlView responses.

Install

Via Composer

$ composer require bcrowe/cakephp-api-pagination

Load the plugin by adding $this->addPlugin('BryanCrowe/ApiPagination'); to the bootsrap method in your project’s src/Application.php:

public function bootstrap(): void
{
    parent::bootstrap();
    
    // ... bootstrap code ...

    // load more plugins here
    
    $this->addPlugin('BryanCrowe/ApiPagination');
}

Usage

Make sure your application has been set up to use data views; see the Enabling Data Views in Your Application section of the CakePHP documentation.

Then, load ApiPaginationComponent:

$this->loadComponent('BryanCrowe/ApiPagination.ApiPagination');

Then, go ahead and set your paginated view variable like so:

$this->set('articles', $this->paginate($this->Articles));
$this->viewBuilder()->setOption('serialize', ['articles']);

Note: It is important that your serialize option is an array, e.g. ['articles'], so that your pagination information can be set under its own pagination key.

Your JsonView and XmlView responses will now contain the pagination information, and will look something like this:

{
    "articles": ["...", "...", "..."],
    "pagination": {
        "finder": "all",
        "page": 1,
        "current": 20,
        "count": 5000,
        "perPage": 20,
        "prevPage": false,
        "nextPage": true,
        "pageCount": 250,
        "sort": null,
        "direction": false,
        "limit": null,
        "sortDefault": false,
        "directionDefault": false
    }
}

Configuring the Pagination Output

ApiPagination has four keys for configuration: key, aliases, visible and model.

key allows you to change the name of the pagination key.
aliases allows you to change names of the pagination detail keys.
visible allows you to set which pagination keys will be exposed in the response. Note: Whenever setting a key's visibility, make sure to use the aliased name if you've given it one.
model allows you to set the name of the model the pagination is applied on if the controller does not follow CakePHP conventions, e.g. ArticlesIndexController. Per default the model is the name of the controller, e.g. Articles for ArticlesController.

An example using all these configuration keys:

$this->loadComponent('BryanCrowe/ApiPagination.ApiPagination', [
    'key' => 'paging',
    'aliases' => [
        'page' => 'currentPage',
        'current' => 'resultCount'
    ],
    'visible' => [
        'currentPage',
        'resultCount',
        'prevPage',
        'nextPage'
    ],
    'model' => 'Articles',
]);

This configuration would yield:

{
    "articles": ["...", "...", "..."],
    "paging": {
        "prevPage": false,
        "nextPage": true,
        "currentPage": 1,
        "resultCount": 20
    }
}
