在记录更新后，PHP头函数无法正常工作

Question

Update查询是这样的，我在更新记录中获得了成功，但是当记录更新后的整个文本框值填写在文本框中时，它不会在页面中重定向，我希望在当前页面上重定向用户，但不使用最后更新的值在空白页上重定向。

 if(isset($_REQUEST['submit']) && $vepariId > 0)
        {
          $update = "UPDATE vepari
                        SET partyId = ".$_REQUEST['partyId'].",
                            vDate = '".$vDate."',
                            veTransType = '".$_REQUEST['veTransType']."',
                            vParti = '".$_REQUEST['vParti']."',
                            vRate = ".$_REQUEST['vRate'].",
                            vDiff = '".$_REQUEST['vDiff']."',
                            vDiffAmt = ".$_REQUEST['vDiffAmt'].",
                            vTotal = ".$_REQUEST['vTotal'].",
                            vTax = ".$_REQUEST['vTax'].",
                            vkg = ".$_REQUEST['vkg'].",
                            vTotalAmt = ".$_REQUEST['vTotalAmt']."
                        WHERE vepariId = ".$vepariId;
          $updateRes= mysql_query($update);
          if($updateRes)
          {
            if($veTransType == 'A')
            {
              $update = "UPDATE mcx 
                          SET 
                          partyId = ".$partyId.",
                          transDate = '".$vDate."',
                          transType = 'J',
                          rate = '".$_REQUEST['vRate']."',
                          kg = '".$_REQUEST['vkg']."',
                          totalAmt = '".$_REQUEST['vTotalAmt']."'
                        WHERE vepariId = ".$vepariId;
              $updateRes = mysql_query($update);
              if(!$updateRes)
              {
                 echo "Mcx Update Fail";
              }
            }
            else
            {
              $update = "UPDATE mcx 
                          SET 
                          partyId = ".$partyId.",
                          transDate = '".$vDate."',
                          transType = 'A',
                          rate = '".$_REQUEST['vRate']."',
                          kg = '".$_REQUEST['vkg']."',
                          totalAmt = '".$_REQUEST['vTotalAmt']."'
                        WHERE vepariId = ".$vepariId;
              $updateRes = mysql_query($update);    
              if(!$updateRes)
              {
                 echo "Mcx Aavak Update Fail";
              }
              else
              {
                header("Location:vepari.php");
              } 
            }
          }
        }

我做了一些修改，请看一下。请记住，当您在页眉前使用回显时，当您在页面中打印某些内容时，最好使用javascript重定向，比如window.location.href。
