Symfony 错误：对字符串调用成员函数setPayrollperiodid（）

我有一个错误，当我尝试创建一个记录时，它给了我这个错误，错误：调用C:\wamp64\www\AgripayrollsystemV2\AgriPayrollSystem\src\com\twcl\agripayrollBundle\Controller\PayrollperiodController.php中字符串上的成员函数setPayrollId（）。此行：*$pWeek->setPayrollperiodid（$entity）；**

实体

    <?php

namespace com\twcl\agripayrollBundle\Entity;


//use Doctrine\Common\Collections\ArrayCollection;
use Symfony\Component\Validator\Constraints as Assert;


/**
 * Payrollperiod
 *

 */
class Payrollperiod
{
    /**
     * @var integer
     *

     */
    private $payrollperiodid;

    /**
     * @var \DateTime
     *

     * @Assert\DateTime()
     */

    private $startdate;

    /**
     * @var \DateTime
     *
     * 
     * @Assert\Type("DateTime")
     * message="The end date must be after the start date")
     */
    private $enddate;

    /**
     * @var integer
     *

     * 
     */
    private $state;

    public function getPayrollperiodid() {
        return $this->payrollperiodid;
    }

    public function getStartdate() {
        return $this->startdate;
    }

    public function getEnddate() {
        return $this->enddate;
    }

    public function getState() {
        return $this->state;
    }

    public function setPayrollperiodid($payrollperiodid) {
        $this->payrollperiodid = $payrollperiodid;
    }

    public function setStartdate(\DateTime $startdate) {
        $this->startdate = $startdate;
    }

    public function setEnddate(\DateTime $enddate) {
        $this->enddate = $enddate;
    }

    public function setState($state) {
        $this->state = $state;
    }

    /**
     * Render a payrollPeriodID as a string.
     * 
     * @return string
     */
     public function __toString()
    {
     return (string) $this->getPayrollperiodid();

    }



}

 return $this
        ->createQueryBuilder('payrollweek')
         ->select('COUNT(pw)')
         ->from ('comtwclagripayrollBundle:Payrollweek','pw')
         ->where ('pw.startdate = :startdate and pw.enddate = :enddate')
        ->setParameter('startdate', $startdate)
        ->setParameter('enddate', $enddate)
        ->getQuery()
        ->getOneorNullResult();
}

自定义存储库

    <?php

namespace com\twcl\agripayrollBundle\Entity;


//use Doctrine\Common\Collections\ArrayCollection;
use Symfony\Component\Validator\Constraints as Assert;


/**
 * Payrollperiod
 *

 */
class Payrollperiod
{
    /**
     * @var integer
     *

     */
    private $payrollperiodid;

    /**
     * @var \DateTime
     *

     * @Assert\DateTime()
     */

    private $startdate;

    /**
     * @var \DateTime
     *
     * 
     * @Assert\Type("DateTime")
     * message="The end date must be after the start date")
     */
    private $enddate;

    /**
     * @var integer
     *

     * 
     */
    private $state;

    public function getPayrollperiodid() {
        return $this->payrollperiodid;
    }

    public function getStartdate() {
        return $this->startdate;
    }

    public function getEnddate() {
        return $this->enddate;
    }

    public function getState() {
        return $this->state;
    }

    public function setPayrollperiodid($payrollperiodid) {
        $this->payrollperiodid = $payrollperiodid;
    }

    public function setStartdate(\DateTime $startdate) {
        $this->startdate = $startdate;
    }

    public function setEnddate(\DateTime $enddate) {
        $this->enddate = $enddate;
    }

    public function setState($state) {
        $this->state = $state;
    }

    /**
     * Render a payrollPeriodID as a string.
     * 
     * @return string
     */
     public function __toString()
    {
     return (string) $this->getPayrollperiodid();

    }



}

 return $this
        ->createQueryBuilder('payrollweek')
         ->select('COUNT(pw)')
         ->from ('comtwclagripayrollBundle:Payrollweek','pw')
         ->where ('pw.startdate = :startdate and pw.enddate = :enddate')
        ->setParameter('startdate', $startdate)
        ->setParameter('enddate', $enddate)
        ->getQuery()
        ->getOneorNullResult();
}

问题是您正在从存储库返回计数而不是实体

因此，如果要设置外键，可以将存储库更改为：

 return $this
        ->createQueryBuilder('pw')
         ->select('pw')
         ->from ('comtwclagripayrollBundle:Payrollweek','pw')
         ->where ('pw.startdate = :startdate and pw.enddate = :enddate')
        ->setParameter('startdate', $startdate)
        ->setParameter('enddate', $enddate)
        ->getQuery()
        ->getResult();

在控制器内部，尝试以下操作：

 elseif (null != $payrollweek){
     foreach ($payrollweek as $entity) {
         $pWeek->setPayrollperiodid($entity); 
         $em->persist($pWeek);
     }
 } 

如果要计算行数，请使用另一个函数

在您的存储库中，您可以有如下内容：

class PayrollweekRepository
{
    public function findBystartdateAndenddate($startdate, $enddate)
    {
       return $this
        ->createQueryBuilder('pw')
         ->select('pw')
         ->from ('comtwclagripayrollBundle:Payrollweek','pw')
         ->where ('pw.startdate = :startdate and pw.enddate = :enddate')
        ->setParameter('startdate', $startdate)
        ->setParameter('enddate', $enddate)
        ->getQuery()
        ->getResult();
    }

    public function countBystartdateAndenddate($startdate, $enddate)
    {
        return $this
        ->createQueryBuilder('payrollweek')
         ->select('COUNT(pw)')
         ->from ('comtwclagripayrollBundle:Payrollweek','pw')
         ->where ('pw.startdate = :startdate and pw.enddate = :enddate')
        ->setParameter('startdate', $startdate)
        ->setParameter('enddate', $enddate)
        ->getQuery()
        ->getOneorNullResult();
    }
}

在控制器内部，您可以将其称为：

$counter = $em->getRepository('comtwclagripayrollBundle:Payrollweek')->countBystartdateAndenddate($form->get('startdate')->getData(), $form->get('enddate')->getData());

尝试打印$payrollweek pleaseresults:array（size=1）1=>string“0”（length=1）在我添加此查询之前，打印效果良好返回$this->createQueryBuilder（'payrollweek'）->select（'COUNT（pw））->from（'comtwclagripayrollBundle:payrollweek'，'pw'）->其中（'pw.startdate=：startdate和pw.enddate=：enddate'）->setParameter（'startdate'，$startdate）->setParameter（'enddate'，$enddate）->getQuery（）->getOneorNullResult（）}此查询用于计算与输入的开始日期和结束日期r=匹配的行数。不知道这是否是问题所在。这是错误，您正试图在pWeek为“0”的位置调用setPayrollperiodid。我不知道为什么，但我假设在您的方法中，findBystartdateAndenddate（如果您编写了它）有点不对劲，或者在实体内部，所以它不应该是for循环，那么我如何修复它们？Alessandro这没有产生我想要的。但是我想知道是否有可能在存储库/控制器中呆一段时间？Hey Alessandro还有可能帮我吗？你可以呆一段时间，但我重复一下，你的问题不清楚，我的建议是ion将以清晰的问题开始一个新问题，这个问题对我来说已经结束，尝试以清晰的问题开始一个新问题，我将帮助你：）嘿，亚历山德罗，我已经创建了一个新问题，你能帮我解决吗？请尽快，我将尝试回答
