错误：在null上调用成员函数setPayrollperiodid（）

标签： php symfony doctrine-orm

我正在尝试计算与输入的工资核算期间相匹配的工资核算周数。它返回正确的数字，但不会添加到数据库，而是说数据库中没有匹配项。当我进行更改时，我收到此错误：

  

错误：在null上调用成员函数setPayrollperiodid（）。

我已经概述了我到目前为止的情况。有人能告诉我哪里出错了。

我已经对问题做了一些更新，我不再收到错误，但记录没有添加，而是说它与控制器中出错的位置不匹配。

存储库

class PayrollweekRepository extends EntityRepository
{
    public function findBystartdateAndenddate($startdate, $enddate)
    {
        $repository = $this->getEntityManager()
            ->getRepository('comtwclagripayrollBundle:Payrollweek');

        $qb = $repository->createQueryBuilder('pw');
        $qb->select('pw');
        $qb->where('pw.startdate=:startdate');
        $qb->Andwhere('pw.enddate=:enddate');
        $qb->setParameter('startdate', $startdate);
        $qb->setParameter('enddate', $enddate);

答案 0 :(得分：0)

在尝试使用之前，您没有检查$payrollweek是否存在。在您的情况下，它在您运行此函数时找不到值：

$payrollweeks = $em->getRepository('comtwclagripayrollBundle:Payrollweek')
    ->findBystartdateAndenddate($entity->getStartDate() , $entity->getEndDate());

由于没有找到任何内容，$payrollweek是NULL而不是 Payrollweek 实体的实例。你可以添加另一个这样的支票：

if (!$payrollweeks) {
    $this->addFlash(
        'error',
        'Error: No payroll week found with the given start and end date'
    );

    return $this->redirect($this->generateUrl('payrollperiod'));
}

编辑基于讨论：

你应该能够摆脱你的countBystartdateAndenddate()功能，只需使用PHP的count()功能来获得你想要的结果，然后循环你的工资周：

$count = count($payrollweeks);

foreach ($payrollweeks as $payrollweek) {
    $payrollweek->setPayrollperiodid($entity); 
}
