ContextErrorException：通知：未定義の変数ですか？

Question

私のコードに問題があります：ContextErrorException：通知：未定義の変数：tpId in /tmxpage/apache/htdocsEDI/Editracker/src/Matrix/MatrixEdiBundle/Controller/MatrixController.php 435行目、symfonyとIの新しいなぜか分からない。ここ

はMatrixController.phpのための私のコードです：

public function checkDocumentAction($docType, $direction, $senderId, $receiverId) { 
    $response = 0; 
    $em =$this->getDoctrine()->getManager(); 
    $temp = $em 
     ->getRepository('MatrixEdiBundle:EdiInterchangeId') 
     ->findInterchangeId($senderId); 
    $countTemp = count($temp); 
    if($temp != null) { 
     if($countTemp == 1) { 
     foreach($temp as $key) { 
      $tpId = $key->getEdiTradingPartner(); 
     } 
     } else { 
     $temp1 = $em 
      ->getRepository('MatrixEdiBundle:EdiInterchangeId') 
      ->findInterchangeId($receiverId); 
     $countTemp1 = count($temp1); 
     if($temp1 != null) { 
      if($countTemp1 == 1) { 
      foreach($temp1 as $key) { 
       $tpId = $key->getEdiTradingPartner(); 
      } 
      } elseif($countTemp1 > 1) { 
      foreach($temp1 as $key) { 
       $temp2 = $key->getEdiTradingPartner(); 
       $temp3 = $em 
        ->getRepository('MatrixEdiBundle:EdiInterchangeId') 
        ->findTradingPartner($temp2, $senderId); 
       $countTemp3 = count($temp3); 
       if($countTemp3 == 1) { 
       foreach($temp3 as $key) { 
        $tpId = $key->getEdiTradingPartner(); 
       } 
       } 
      } 
      } 
     } 
     } 

     if ($tpId != null) { 
     $result = $em 
      ->getRepository('MatrixEdiBundle:EdiTradingPartnerTransactions') 
      ->getTpTrans($tpId, $docType, $direction); 
     // if ($result != null) { 
     // $response = 1; 
     // } 
     if ($result != null) { 
      foreach ($result as $key) { 
      $isRequired = $key->getIsRequired(); 
      if ($isRequired == 1) { 
       $response = 1; 
      } else { 
       $response = 2; 
      } 
      } 
     } 
     } 
    } 

    return new Response($response); 
} 

それはここで

matrixcontroller.php内部関数のTPIDがあるrejectedTrans.html.twigのための私の抜粋ですテンプレートのレンダリング中に例外がスローされました（ "Notice：未定義変数：tpId、：

$ tpIdは条件でのみ初期化されます。したがって、すべての条件がfalseの場合、変数は定義されません。

がヌルでそれを初期化し

public function checkDocumentAction($docType, $direction, $senderId, $receiverId) { 
    $response = 0; 
    $tpId = null;
