# Pagination

## Overview
A paginator is a component which helps with splitting a large amount of data gradually. An example would be displaying all the posts of a blog, 5 at a time. The Phalcon Paginator accepts parameters and based on those returns the relevant _slice_ of the whole resultset so that the developer can present the paginated data. 

```php
<?php 

declare(strict_types=1);

use Phalcon\Paginator\Adapter\NativeArray;

$currentPage = 2;
$paginator   = new NativeArray(
[
    "data"  => [
        ["id" => 1, "name" => "Artichoke"],
        ["id" => 2, "name" => "Carrots"],
        ["id" => 3, "name" => "Beet"],
        ["id" => 4, "name" => "Lettuce"],
        ["id" => 5, "name" => ""],
    ],
    "limit" => 2,
    "page"  => $currentPage,
]
 );

$paginate = $paginator->paginate();
```

The example above uses an array as the source, and limits the results to 2 records at a time. It will return elements with id `3` and `4` because the `page` has been set to `2`. 

## Adapters
For the source of the data, the component uses adapters. It comes with the following adapters: 

| Adapter                                                                  | Description                                                                            |
|--------------------------------------------------------------------------|----------------------------------------------------------------------------------------|
| [Phalcon\Paginator\Adapter\Model][paginator-adapter-model]               | Use a [Phalcon\Mvc\Model\Resultset][mvc-model-resultset] object as source data.        |
| [Phalcon\Paginator\Adapter\NativeArray][paginator-adapter-nativearray]   | Use a PHP array as source data                                                         |
| [Phalcon\Paginator\Adapter\QueryBuilder][paginator-adapter-querybuilder] | Use a [Phalcon\Mvc\Model\Query\Builder][mvc-model-query-builder] object as source data |

:::warning[NOTE]
Since PDO does not support scrollable cursors, [Phalcon\Paginator\Adapter\Model][paginator-adapter-model] should not be used to paginate a large number of records
:::

### Methods
```php
public function __construct(array $config)
```

Every adapter requires options to operate properly. These options are passed as a key/value array in the constructor of the adapter.

| Option          | Description                                                                                                                                                   |
|-----------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `builder`       | Used only for the [Phalcon\Paginator\Adapter\QueryBuilder][paginator-adapter-querybuilder] to pass the builder object                                         |
| `data`          | The data to paginate. ([Phalcon\Paginator\Adapter\NativeArray][paginator-adapter-nativearray] adapter)                                                        |
| `limit` (`int`) | The size of the page slice. If `limit` is negative, an exception will be thrown.                                                                              |
| `model`         | The data to paginate. ([Phalcon\Paginator\Adapter\Model][paginator-adapter-model] adapter)                                                                    |
| `page` (`int`)  | The current page                                                                                                                                              | 
| `repository`    | [Phalcon\Paginator\RepositoryInterface][paginator-repositoryinterface] - A repository object setting up the resultset. For more about repositories see below. | 

The methods exposed are:

| Method                                                             | Description                            |
|--------------------------------------------------------------------|----------------------------------------|
| `getLimit(): int`                                                  | Get current rows limit                 |
| `getRepository(array $properties = null): RepositoryInterface`     | Gets current repository for pagination |
| `setCurrentPage(int $page): AdapterInterface`                      | Set the current page number            |
| `setLimit(int $limitRows): AdapterInterface`                       | Set current rows limit                 |
| `setRepository(RepositoryInterface $repository): AdapterInterface` | Sets current repository for pagination |

### Model
The [Phalcon\Paginator\Adapter\Model][paginator-adapter-model] adapter uses a [Phalcon\Mvc\Model\Resultset][mvc-model-resultset] as the source of the data. This is the result of the `find()` method on a model.

```php
<?php
declare(strict_types=1);

use MyApp\Models\Invoices;
use Phalcon\Paginator\Adapter\Model;

$currentPage = 2;
$paginator   = new Model(
[
    "model"      => Invoices::class,
    "parameters" => [
        "inv_cst_id = :cst_id:",
          "bind" => [
              "cst_id" => 1
          ],
          "order" => "inv_title"
    ],
    "limit"      => 25,
    "page"       => $currentPage,
]
);

$paginate = $paginator->paginate();
```

The array accepts `model` for the model class to be used. The method `find()` will be called on it. Additionally, this adapter can accept `parameters` as the array that `find()` can use with all the relevant conditionals required.

### Array
The [Phalcon\Paginator\Adapter\NativeArray][paginator-adapter-nativearray] accepts a PHP array as the source of the data.

```php
<?php
declare(strict_types=1);

use Phalcon\Paginator\Adapter\NativeArray;

$currentPage = 2;
$paginator   = new NativeArray(
[
    "data"  => [
        ["id" => 1, "name" => "Artichoke"],
        ["id" => 2, "name" => "Carrots"],
        ["id" => 3, "name" => "Beet"],
        ["id" => 4, "name" => "Lettuce"],
        ["id" => 5, "name" => ""],
    ],
    "limit" => 2,
    "page"  => $currentPage,
]
);

$paginate = $paginator->paginate();
```

### Query Builder
The [Phalcon\Paginator\Adapter\QueryBuilder][paginator-adapter-querybuilder] adapter uses a [Phalcon\Mvc\Model\Query\Builder][mvc-model-query-builder] object to perform a PHQL query against the database. 

```php
<?php
declare(strict_types=1);

use MyApp\Models\Invoices;
use Phalcon\Paginator\Adapter\QueryBuilder;

$builder = $this
->modelsManager
->createBuilder()
->columns("inv_id, inv_title")
->from(Invoices::class)
->orderBy("inv_title");

$paginator = new QueryBuilder(
[
    "builder" => $builder,
    "limit"   => 20,
    "page"    => 1,
]
);

$paginate = $paginator->paginate();
```

## Repository
The `paginate()` method does all the work to paginate the data. It returns a [Phalcon\Paginator\Repository][paginator-repository] object which stores all the necessary elements for the pagination. The object exposes the following constants:

- `PROPERTY_CURRENT_PAGE`  = "current";
- `PROPERTY_FIRST_PAGE`    = "first";
- `PROPERTY_ITEMS`         = "items";
- `PROPERTY_LAST_PAGE`     = "last";
- `PROPERTY_LIMIT`         = "limit";
- `PROPERTY_NEXT_PAGE`     = "next";
- `PROPERTY_PREVIOUS_PAGE` = "previous";
- `PROPERTY_TOTAL_ITEMS`   = "total_items";

### Methods
The methods exposed are:

| Methods                                                 | Description                                  |
|---------------------------------------------------------|----------------------------------------------|
| `getAliases(): array`                                   | Gets the aliases for properties repository   |
| `getCurrent(): int`                                     | Gets number of the current page              |
| `getFirst(): int`                                       | Gets number of the first page                |
| `getItems(): mixed`                                     | Gets the items on the current page           |
| `getLast(): int`                                        | Gets number of the last page                 |
| `getLimit(): int`                                       | Gets current rows limit                      |
| `getNext(): int`                                        | Gets number of the next page                 |
| `getPrevious(): int`                                    | Gets number of the previous page             |
| `getTotalItems(): int`                                  | Gets the total number of items               |
| `setAliases(array $aliases): RepositoryInterface`       | Sets the aliases for properties repository   |
| `setProperties(array $properties): RepositoryInterface` | Sets values for properties of the repository |

You can access the data by using the methods above or use the magic properties as defined in the constants:

```php
<?php

use Phalcon\Paginator\Adapter\NativeArray;

$currentPage = 2;
$paginator   = new NativeArray(
[
    "data"  => [
        ["id" => 1, "name" => "Artichoke"],
        ["id" => 2, "name" => "Carrots"],
        ["id" => 3, "name" => "Beet"],
        ["id" => 4, "name" => "Lettuce"],
        ["id" => 5, "name" => ""],
    ],
    "limit" => 2,
    "page"  => $currentPage,
]
);

$paginate = $paginator->paginate();

echo $paginate->getCurrent();    // 2
echo $paginate->current     ;    // 2
echo $paginate->getFirst();      // 1
echo $paginate->first;           // 1
var_dump($paginate->getItems());  
// [
//     [
//         'id'   => 3
//         'name' => "Beet",
//     ],
//     [
//         'id'   => 4,
//         'name' => "Lettuce",
//     ]
// ]
var_dump($paginate->getItems());  
echo $paginate->getLast();       // 3
echo $paginate->last;            // 3
echo $paginate->getLimit();      // 2
echo $paginate->limit;           // 2
echo $paginate->getNext();       // 3
echo $paginate->next;            // 3
echo $paginate->getPrevious();   // 1
echo $paginate->previous;        // 1
echo $paginate->getTotalItems(); // 5 
echo $paginate->total_items;     // 5 
```

### Aliases
If you want to use your own names for each magic property the Repository object exposes, you can use the `setAliases()` method to do so.

```php
<?php
declare(strict_types=1);

use Phalcon\Paginator\Repository;
use Phalcon\Paginator\Adapter\NativeArray;

$repository = = new Repository();
$repository->setAliases(
[
    'myCurrentPage' => $repository::PROPERTY_CURRENT_PAGE,
    'myFirstPage'   => $repository::PROPERTY_FIRST_PAGE,
    'myLastPage'    => $repository::PROPERTY_LAST_PAGE,
    'myLimit'       => $repository::PROPERTY_LIMIT,
    'myNextPage'    => $repository::PROPERTY_NEXT_PAGE,
    'myTotalItems'  => $repository::PROPERTY_TOTAL_ITEMS,
]
);

$currentPage = 2;
$paginator   = new NativeArray(
[
    "data"       => [
        ["id" => 1, "name" => "Artichoke"],
        ["id" => 2, "name" => "Carrots"],
        ["id" => 3, "name" => "Beet"],
        ["id" => 4, "name" => "Lettuce"],
        ["id" => 5, "name" => ""],
    ],
    "limit"      => 2,
    "page"       => $currentPage,
    'repository' => $repository,
]
);

$paginate = $paginator->paginate();

echo $paginate->myCurrentPage;   // 2
echo $paginate->myFirstPage;     // 1
echo $paginate->myLastPage;      // 3
echo $paginate->myLimit;         // 2
echo $paginate->myNextPage;      // 3
echo $paginate->myTotalItems;    // 1
```

You can also create your custom repository class by implementing the [Phalcon\Paginator\RepositoryInterface][paginator-repositoryinterface] interface.

## Factory
You can use the Pagination Factory class to instantiate a new paginator object. The names of the services are:

| Name           | Class                                                                    |
|----------------|--------------------------------------------------------------------------|
| `model`        | [Phalcon\Paginator\Adapter\Model][paginator-adapter-model]               |
| `nativeArray`  | [Phalcon\Paginator\Adapter\NativeArray][paginator-adapter-nativearray]   |
| `queryBuilder` | [Phalcon\Paginator\Adapter\QueryBuilder][paginator-adapter-querybuilder] |

### newInstance
One method that you can use is `newInstance()`:

```php
<?php
declare(strict_types=1);

use MyApp\Models\Invoices;
use Phalcon\Paginator\PaginatorFactory;

$builder = $this
->modelsManager
->createBuilder()
->columns('inv_id, inv_title')
->from(Invoices::class)
->orderBy('name')
;

$options = [
'builder' => $builder,
'limit'   => 20,
'page'    => 1,
];

$factory   = new PaginatorFactory();
$paginator = $factory->newInstance('queryBuilder');

```

### Load
Loads Paginator Adapter class using `adapter` option. The configuration passed can be an array or a [Phalcon\Config\Config][config] object with the necessary entries for the class to be instantiated.

```php
<?php
declare(strict_types=1);

use MyApp\Models\Invoices;
use Phalcon\Paginator\PaginatorFactory;

$builder = $this
->modelsManager
->createBuilder()
->columns('inv_id, inv_title')
->from(Invoices::class)
->orderBy('inv_title')
;

$options = [
'builder' => $builder,
'limit'   => 20,
'page'    => 1,
'adapter' => 'queryBuilder',
];

$paginator = (new PaginatorFactory())->load($options);
```

A sample configuration object is:

```ini
[paginator]
adapter = queryBuilder
options.limit = 20
options.page = 1
```

The configuration expects an element `adapter` for the relevant adapter and an `options` array with the necessary options for the adapter.

## Exception
Any exceptions thrown in the Paginator component will be of type [Phalcon\Paginator\Exception][paginator-exception]. You can use this exception to selectively catch exceptions thrown only from this component.

```php
<?php

use Phalcon\Paginator\Adapter\NativeArray;
use Phalcon\Paginator\Exception;

try {
$currentPage = 2;
$paginator   = new NativeArray(
    [
        "data"  => [
            ["id" => 1, "name" => "Artichoke"],
            ["id" => 2, "name" => "Carrots"],
            ["id" => 3, "name" => "Beet"],
            ["id" => 4, "name" => "Lettuce"],
            ["id" => 5, "name" => ""],
        ],
        "limit" => -5,
        "page"  => $currentPage,
    ]
);

$paginate = $paginator->paginate();
} catch (Exception $ex) {
echo $ex->getMessage();
}
```

## Examples
In the example below, the paginator will use the result of a query from a model as its source data, and limit the displayed data to 10 records per page:

### Full
```php
<?php
declare(strict_types=1);

use MyApp\Models\Invoices;
use Phalcon\Http\Request;
use Phalcon\Mvc\Controller;
use Phalcon\Mvc\View;
use Phalcon\Paginator\Adapter\Model as PaginatorModel;

/**
 * @property Request $request
 * @property View    $view
 */
class InvoicesController extends Controller
{
public function listAction()
{
    $currentPage = $this->request->getQuery('page', 'int', 1);
    $paginator   = new PaginatorModel(
        [
            'model'  => Invoices::class,
            'limit' => 10,
            'page'  => $currentPage,
        ]
    );

    $page = $paginator->paginate();

    $this->view->setVar('page', $page);

}
}
```

In the example above `$currentPage` contains an integer, user supplied variable, for the page to be displayed. The `$paginator->paginate()` returns a [Phalcon\Paginator\Repository][paginator-repository] object that contains the paginated data. It can be used for generating the pagination in a view for instance:

```php
<table>
<tr>
    <th>Id</th>
    <th>Status</th>
    <th>Title</th>
</tr>
<?php foreach ($page->getItems() as $item) { ?>
<tr>
    <td><?php echo $item['inv_id']; ?></td>
    <td><?php echo ($item['inv_status_flag']) ? 'Paid' : ''; ?></td>
    <td><?php echo $item['inv_title']; ?></td>
</tr>
<?php } ?>
</table>
```

The `$page` object also contains navigation data:

```php
<a href="/invoices/list">First</a>
<a href="/invoices/list?page=<?= $page->getPrevious(); ?>">Previous</a>
<a href="/invoices/list?page=<?= $page->getNext(); ?>">Next</a>
<a href="/invoices/list?page=<?= $page->getLast(); ?>">Last</a>

<?php echo "Page {$page->getCurrent()}  of {$page->getLast()}"; ?>
```

### Factory
You can instantiate a Paginator class using the `AdapterFactory`.

**Model**
```php
<?php
declare(strict_types=1);

use MyApp\Models\Invoices;
use Phalcon\Paginator\PaginatorFactory;

$factory = new PaginatorFactory();

$currentPage = 2;
$options     = [
   'model' => Invoices::class,
   'limit' => 10,
   'page'  => $currentPage,
];

$paginator = $factory->newInstance('model', $options);
```

**Array**
```php
<?php
declare(strict_types=1);

use MyApp\Models\Invoices;
use Phalcon\Paginator\PaginatorFactory;

$factory = new PaginatorFactory();

$currentPage = 2;
$options     = [
'data'  => [
    ['id' => 1, 'name' => 'Artichoke'],
    ['id' => 2, 'name' => 'Carrots'],
    ['id' => 3, 'name' => 'Beet'],
    ['id' => 4, 'name' => 'Lettuce'],
    ['id' => 5, 'name' => ''],
],
'limit' => 2,
'page'  => $currentPage,
];

$paginator = $factory->newInstance('nativeArray', $options);
```

```php
<?php
declare(strict_types=1);

use MyApp\Models\Invoices;
use Phalcon\Paginator\PaginatorFactory;

$factory = new PaginatorFactory();

$currentPage = 2;
$builder     = $this
->modelsManager
->createBuilder()
->columns('id, name')
->from('Robots')
->orderBy('name');
$options = [
'builder' => $builder,
'limit'   => 20,
'page'    => $currentPage,
];

$paginator = $factory->newInstance('queryBuilder', $options);
```

### Individual Classes
An example of the source data that must be used for each adapter:

**Model**
```php
<?php
declare(strict_types=1);

use Phalcon\Paginator\Adapter\Model as PaginatorModel;

$currentPage = 2;
$paginator   = new PaginatorModel(
[
   'model'  => Invoices::class,
   'limit' => 10,
   'page'  => $currentPage,
]
);
```

**Array**
```php
<?php
declare(strict_types=1);

use Phalcon\Paginator\Adapter\NativeArray as PaginatorArray;

$currentPage = 2;
$paginator   = new PaginatorArray(
[
    'data'  => [
        ['id' => 1, 'name' => 'Artichoke'],
        ['id' => 2, 'name' => 'Carrots'],
        ['id' => 3, 'name' => 'Beet'],
        ['id' => 4, 'name' => 'Lettuce'],
        ['id' => 5, 'name' => ''],
    ],
    'limit' => 2,
    'page'  => $currentPage,
]
);
```

**Query Builder**
```php
<?php
declare(strict_types=1);

use MyApp\Models\Invoices;
use Phalcon\Paginator\Adapter\QueryBuilder as PaginatorQueryBuilder;

$currentPage = 2;
$builder     = $this
->modelsManager
->createBuilder()
->columns('id, name')
->from('Robots')
->orderBy('name');

$paginator = new PaginatorQueryBuilder(
[
    'builder' => $builder,
    'limit'   => 20,
    'page'    => $currentPage,
]
);
```

## Custom
The [Phalcon\Paginator\AdapterInterface][paginator-adapter-adapterinterface] interface must be implemented in order to create your own paginator adapters or extend the existing ones:

```php
<?php
declare(strict_types=1);

use Phalcon\Paginator\AdapterInterface as PaginatorInterface;
use Phalcon\Paginator\RepositoryInterface;

class MyPaginator implements PaginatorInterface
{
/**
 * Get current rows limit
 */
public function getLimit(): int;

/**
 * Returns a slice of the resultset to show in the pagination
 */
public function paginate(): RepositoryInterface;

/**
 * Set the current page number
 */
public function setCurrentPage(int $page);

/**
 * Set current rows limit
 */
public function setLimit(int $limit);
}
```
