我有一个 mysql 数据库博客,里面有 21 个帖子。我设置 $maxPerPage = '3'; 所以我得到 7 页,但从第 4 页开始出现以下错误:
OutOfRangeCurrentPageException:页面“4”不存在。currentPage 必须低于“3”
这是我的代码:
public function indexAction($page)
{
$maxPerPage = '3';
$currentPage = $page;
$entityManager = $this->getDoctrine()->getManager();
$queryBuilder = $entityManager->createQueryBuilder()
->select(array('u')) // string 'u' is converted to array internally
->from('AppBundle:Blog', 'u');
$adapter = new DoctrineORMAdapter($queryBuilder);
$pagerfanta = new Pagerfanta($adapter);
if (!$page) $currentPage = '1';
try {
$pagerfanta->setCurrentPage($currentPage);
}
catch(NotValidCurrentPageException $e) {
throw new NotFoundHttpException('Illegal page');
}
$pagerfanta->setMaxPerPage($maxPerPage); // 10 by default
//$textblog = $this->getDoctrine()
//->getRepository('AppBundle:Blog')
//->find($page);
return $this->render('textblog/blog.html.twig',array('pagerfanta' => $pagerfanta));
}
有人可以帮忙吗?
