Question

我寫的代碼在下面給出控制器，

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

，我使變量$ paginatorDatas查看文件。

在對應的視圖文件中，我已經寫這樣的代碼，

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

之前調用$這 - > paginationControl（）函數我已經迭代數組對象（$ paginatorDatas），通過foreach(){}填充記錄。

但上面的代碼提供了以下錯誤，

致命錯誤 ：未捕獲的異常「的Zend \ DB \適配器\異常\的RuntimeException」與消息「這一結果是僅正向結果集，調用倒帶（）之後向前移動不支持'/var/www/cp/vendor/zendframework/zendframework/library/Zend/Db/Adapter/Driver/Pdo/Result.php:153堆棧軌跡：＃0 [內部函數]：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-> ren der（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 [內部函數]：Zend \ Mvc \ View \ Http \ DefaultRenderingStrategy-> render（Object（Zend \ Mvc \ MvcEvent））＃6/var/www在線/ CP /在/var/www/cp/vendor/zendframework/zendframework/library/Zend/Db/Adapter/Driver/Pdo/Result.php 153

請幫我....

方法1

$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);

方法2

$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); 

Answer 2

用您的查詢結果填充陣列，您可以使用\Zend\Paginator\Adapter\ArrayAdapter代替\Zend\Paginator\Adapter\Iterator
