Question

我有以下正确运行的查询：

$q = $this->createQuery('e')
     ->where('e.Persons_idUser =?', $request)
     ->leftJoin('e.JobTitles jt')
     ->leftJoin('e.EmploymentLevels el');

但是当我迭代结果并尝试访问左连接中的字段时：

 foreach ($work as $w){
   echo $w->employername;
   echo $w->jobtitle; // this is from the left join
   echo $w->employmentlevel; // this is from the left join
 }

我收到以下错误消息： “经验”上的未知记录属性/相关组件“jobtitle”

任何人都有线索？如何回显左连接中的字段？

Answer 1

<?php
    foreach ($work as $w){
        echo $w->employername;
        foreach($w->JobTitles as $job){
            echo $job->jobtitle; // this is from the left join
        }
        foreach($w->EmploymentLevels as $employ){
            echo $employ->employmentlevel; // this is from the left join
        }
    }

?>

当symfony返回对象数组并且连接表中的元素位于子数组

下时，这将起作用

Answer 2

解决方案：

foreach ($work as $w){
 echo $w->employername;
 echo $w->JobTitles->jobtitle; // this is from the left join
 echo $w->EmploymentLevels->employmentlevel; // this is from the left join
}

Symfony离开了连接查询
