设置参数的学说 2 查询生成器不起作用 [英] doctrine 2 querybuilder with set parameters not working

问题描述

这是我的查询:

公共函数getDetails($userid, $orderby, $sort){

public function getDetails($userid, $orderby, $sort){

$query = $this->_em->createQueryBuilder()
                ->select('u')
                ->from('EntitiesUsers', 'u')
                ->where('u.userid= ?1')
                ->orderBy('u.?3', '?3')
                ->setParameter(1, $userid)
                ->setParameter(2, $orderby)
                ->setParameter(3, $sort)
                ->getQuery()
                ->getResult();

}

它一直出错:消息:[Semantical Error] line 0, col 83 near '?3 DESC': Error: '?3' is not defined.

it keeps erroring: Message: [Semantical Error] line 0, col 83 near '?3 DESC': Error: '?3' is not defined.

如何从该函数的属性中获取 orderby 到查询?

how do i get the orderby from the properties in that function to the query?

推荐答案

您不能将占位符用于 DQL 查询的动态构建.您必须自己编写代码:

You can't use placeholders for dinamical build of DQL query. You'll have to code it by your own:

$sortBy = in_array($sortBy, array(...)) ? $sortBy : 'id';
$sortDir = $sortDir == 'ASC' ? 'ASC' : 'DESC';

$this->em->createQueryBuilder()
    ...
    ->orderBy('u.' . $sortBy, $sortDir)
