Doctrine2 Paginator获得总成绩 [英] Doctrine2 Paginator getting total results

问题描述

我马上要说，我读了这个问题 Doctrine2 Paginator ，但是它没有给我有关我的问题标题的足够信息.

Right away I would say, that I read this question Doctrine2 Paginator, but it doesn't give me enough information regarding the title of my question.

使用Doctrine1时，例如，使用以下代码获取结果:

When I used Doctrine1 I was getting the result with such code for example:

$list = $this->query
    ->addSelect( 'SQL_CALC_FOUND_ROWS *' )
    ->offset( ( $this->currentPage - 1 ) * $this->perPage )
    ->limit( $this->perPage )
    ->execute( array(), \Doctrine_Core::HYDRATE_ARRAY_SHALLOW );

$totalRecords     = SqlCalcFoundRowsEventListener::getFoundRowsCount();
$this->totalPages = ceil( $totalRecords / $this->perPage );

很棒.

现在，当使用Doctrine2时，我对如何获取具有相同查询的记录总数作为当前页面的有限结果感到困惑.

Now, when using Doctrine2 I'm confused on how should I get total amount of records with same query as limited result for current page.

任何帮助/建议将不胜感激.

Any help/advice would be greatly appreciated.

推荐答案

分页器用法如下:

$paginator  = new \Doctrine\ORM\Tools\Pagination\Paginator($query);

$totalItems = count($paginator);
$pagesCount = ceil($totalItems / $pageSize);

// now get one page's items:
$paginator
    ->getQuery()
    ->setFirstResult($pageSize * ($currentPage-1)) // set the offset
    ->setMaxResults($pageSize); // set the limit

foreach ($paginator as $pageItem) {
    echo "<li>" . $pageItem->getName() . "</li>";
}
