我在从invoiceitem表更新提取的数据时遇到问题,以更新产品表quantity
。
此问题只是我的循环中第一条正在更新的记录。
请帮我更新数据库中的多个项目值。
这是我的代码:
<?php
$stuid = $_GET['id'];
global $con;
$stu_query = "SELECT * FROM invoiceorder INNER JOIN invoiceorderitem ON invoiceorder.InvoId = invoiceorderitem.InvoId WHERE invoiceorder.InvoId ='$stuid'";
$stu_run = mysqli_query($con,$stu_query);
while($sorows = mysqli_fetch_array($stu_run)){
$Date = $sorows['Date'];
$SalesPerson = $sorows['SalesPerson'];
$Telephone = $sorows['Telephone'];
$Customer = $sorows['Customer'];
$CurrentPayment = $sorows['CurrentPayment'];
$Balance = $sorows['Balance'];
$Item_Id = $sorows['Item_Id'];
$ItemDescription = $sorows['ItemDescription'];
$UnitPrice = $sorows['UnitPrice'];
$Quantity = $sorows['Quantity'];
$SubTotal = $sorows['SubTotal'];
$Total = $sorows['Total'];
$sea_res = mysqli_query($con, "SELECT * FROM bincard WHERE BinId = $Item_Id");
while ($resresults = $sea_res->fetch_assoc()){
$BinId = $resresults['BinId'];
$ItemName = $resresults['ItemName'];
$QtyBalance = $resresults['QtyBalance'];
$QtyIssued = $resresults['QtyIssued'];
//chech this
$newqty=0;
$isuqty=0;
$newqty =$QtyBalance - $Quantity;
$isuqty = $QtyIssued + $Quantity;
$insert_query = "UPDATE bincard SET QtyBalance='$newqty',QtyIssued='$isuqty' WHERE BinId = $Item_Id";
}
if ($con->query($insert_query) === TRUE)
{
echo"<script>alert(' Updated Successfully')</script>";
echo"<script>window.open('invoiceprint.php','_self')</script>";
} else
{
echo "Error: " . $insert_query . "<br>" . $con->error;
}
$con->close();
}
?>
答案 0 :(得分:1)
将if ($con->query($insert_query) === TRUE)
放入while
循环中。如果它只更新一条记录,那么$sea_res->fetch_assoc()
只有一条记录。
while ($resresults = $sea_res->fetch_assoc()){
$BinId = $resresults['BinId'];
$ItemName = $resresults['ItemName'];
$QtyBalance = $resresults['QtyBalance'];
$QtyIssued = $resresults['QtyIssued'];
//chech this
$newqty=0;
$isuqty=0;
$newqty =$QtyBalance - $Quantity;
$isuqty = $QtyIssued + $Quantity;
$insert_query = "UPDATE bincard SET QtyBalance='$newqty',QtyIssued='$isuqty' WHERE BinId = $Item_Id";
if ($con->query($insert_query) === TRUE)
{
echo"<script>alert(' Updated Successfully')</script>";
echo"<script>window.open('invoiceprint.php','_self')</script>";
} else{
echo "Error: " . $insert_query . "<br>" . $con->error;
}
}
