无法获得 ZF2 分页

Question

我已经在下面给出的控制器中编写了代码，

$iteratorAdapter  = new \Zend\Paginator\Adapter\Iterator($this->getCategoryTable()->listCategoryData());
$paginatorDatas = new \Zend\Paginator\Paginator($iteratorAdapter);
$paginatorDatas->setCurrentPageNumber($page)->setItemCountPerPage(5); 

然后我渲染变量 $paginatorDatas 来查看文件。

在对应的视图文件中，我写了这样的代码，

echo $this->paginationControl($this->paginatorDatas, 'Elastic', 'paginator.phtml');

在调用 $this->paginationControl() 函数之前，我已经通过 foreach(){} 迭代了数组对象 ($paginatorDatas) 以填充记录。

但上面的代码给出了以下错误，

致命错误：未捕获的异常 'Zend\Db\Adapter\Exception\RuntimeException' 并在 /var/www/cp/ 中显示消息“此结果是仅向前的结果集，不支持向前移动后调用 rewind()”供应商/zendframework/zendframework/library/Zend/Db/Adapter/Driver/Pdo/Result.php:153 堆栈跟踪：#0 [内部函数]：Zend\Db\Adapter\Driver\Pdo\Result->rewind()# 1 /var/www/cp/module/Admin/view/admin/category/ajax-list.phtml(21): LimitIterator->rewind() #2 /var/www/cp/vendor/zendframework/zendframework/library/ Zend/View/Renderer/PhpRenderer.php(507): include('/var/www/cp/mod...') #3 /var/www/cp/vendor/zendframework/zendframework/library/Zend/View/ View.php(205): Zend\View\Renderer\PhpRenderer->render(Object(Zend\View\Model\ViewModel)) #4 /var/www/cp/vendor/zendframework/zendframework/library/Zend/Mvc/ View/Http/DefaultRenderingStrategy.php(102): Zend\View\View->render(Object(Zend\View\Model\ViewModel)) #5【内部函数】: Zend\Mvc\View\Http\DefaultRenderingStrategy->render （OB ject(Zend\Mvc\MvcEvent)) #6 /var/www/cp/ in /var/www/cp/vendor/zendframework/zendframework/library/Zend/Db/Adapter/Driver/Pdo/Result.php 在第 153 行

请帮帮我....

方法一

$resultSet = $this->getCategoryTable()->listCategoryData();
$resultSet->buffer();
$resultSet->next();
$iteratorAdapter  = new \Zend\Paginator\Adapter\Iterator($resultSet);
$paginatorDatas = new \Zend\Paginator\Paginator($iteratorAdapter);
$paginatorDatas->setCurrentPageNumber($page)->setItemCountPerPage(5);

来自this Samsonasik 的教程

方法二

$resultSet = $this->getCategoryTable()->listCategoryData();
$resultSet = iterator_to_array($resultSet);
$adapter  = new \Zend\Paginator\Adapter\ArrayAdapter($resultSet);
$paginatorDatas = new \Zend\Paginator\Paginator($adapter);
$paginatorDatas->setCurrentPageNumber($page)->setItemCountPerPage(5);

用您的查询结果填充一个数组，您可以使用\Zend\Paginator\Adapter\ArrayAdapter 而不是\Zend\Paginator\Adapter\Iterator
