Question

在我的应用程序中，我想使用Zend Framework 2的分页器。我遇到的问题是我从我的表中得到一个对象结果集一个数组。

我可以通过使用foreach循环遍历对象并生成新数组来简单地解决这个问题。但在我看来，这是一种解决方法，并没有必要这样做。

我的桌子代码：

VideosTable.php

namespace Application\Model;

use Zend\Db\Sql\Expression;
use Zend\Db\TableGateway\AbstractTableGateway;
use Zend\Db\Adapter\Adapter;
use Zend\Db\ResultSet\ResultSet;
use Zend\Db\Sql\Select;
use Zend\Db\Sql\Sql;
use Zend\Db\Sql\Where;
use Application\Model\Videos;

class VideosTable extends AbstractTableGateway
{
    protected $table = 'videos';

    public function __construct(Adapter $adapter)
    {
        $this->adapter = $adapter;
        $this->resultSetPrototype = new ResultSet();
        $this->resultSetPrototype->setArrayObjectPrototype(new Videos());

        $this->initialize();
    }

    /**
     * Get movie list
     */
    public function getMovies($limit, $order, $array = null)
    {
        $select = new Select();
        $select->from($this->table);
        $select->order('id', $order)->limit($limit);

        $resultSet = $this->selectWith($select);

        return $resultSet;
    }
}

我在控制器中设置的分页器：

public function indexAction()
    {   
        $select    = new Select();
        $page      = $this->params()->fromRoute('page') ? (int) $this->params()->fromRoute('page') : 1;
        $videos    = $this->getVideosTable()->getMovies(25, 'DESC');

        // could do like this but looks not necessary / dirty
        foreach ($videos as $key => $video) :
            $data[] = array('video_title' => $video->video_title);          
        endforeach;


        $paginator = new Paginator(new \Zend\Paginator\Adapter\ArrayAdapter($data));
        $paginator->setCurrentPageNumber($page)
                  ->setItemCountPerPage(11)
                  ->setPageRange(7);
etc..

更改你的getMovies方法以返回类似这样的内容

/**
 * Get movie list
 */
public function getMovies($limit, $order, $array = null)
{
    $select = new Select();
    $select->from($this->table);
    $select->order('id', $order)->limit($limit);

    return new \Zend\Paginator\Paginator(
        new \Zend\Paginator\Adapter\DbSelect($select, $this->adapter, $this->resultSetPrototype)
    );
}

然后你可以随心所欲地使用控制器中的分页器。它还允许你从getMovies（）方法中抛弃限制逻辑，因为它将由paginator处理。

抛弃限制逻辑（因为它由分页器处理）看起来像这样

/**
 * Get movie list
 */
public function getMovies($order = 'DESC')
{
    $select = $this->getSql()->select();
    $select->order('id', $order);

    return new \Zend\Paginator\Paginator(
        new \Zend\Paginator\Adapter\DbSelect($select, $this->adapter, $this->resultSetPrototype)
    );
}

ZF2使用paginator和对象结果集
