Unable to block while loop repeats - php

Question

Working on invoice module which has two different tables master_table and detail_table. Know i want to display master_table's data above the table then in the table structure showing data of detail_table for each three rows header.
My code looks this.
$n = 0;
$htmlpage = 1;
$query = $dbConnection->prepare("SELECT * FROM master WHERE (DocNo BETWEEN ? AND ?) ORDER BY DocNo ASC");
$query->execute(array($fdcu,$tdcu));
while($rows = $query->fetch())
{
$n++;
$noInvs = $rows['No_of_Inv'];
$dno = $rows['DocNo'];
$name = $rows['Customer_Name'];
Step-1: Now i'm pulling client data from another table
$qry = $dbConnection->prepare("SELECT * FROM client WHERE client_name=?");
$qry->execute(array($name));
$row = $qry->fetch();
$add = $row['address'];
$city = $row['city'];
$proj = $rows['Project'];
$projNo = $rows['Project_No'];
$sermnth = $rows['Service_Month'];
$grandtotal = $rows['Total_Amt'];
$rupee = number2word($grandtotal);
$index = 1;
$ratetot = 0;
$subtotal = 0;
$lastPage = ceil($noInvs/3);
$pageCount = 0;
Step-2: Now check the loop iteration
while($index <= $noInvs)
{
$cnt = 1;
$body = "<div class='main-container'><table width='100%' style='padding:0 0 0 0;' align='center' cellpadding='0' cellspacing='0'>

<td style='width:15%;text-align:center; border-bottom:solid 1px #000000;padding:3px 5px 3px 5px;font-size:12px;'>Amount in Rs.</td>
</tr>";
Step-4: check the loop condition
while(true)
{
Step-5: checking the iteration count
if($cnt>3)
{
$pageCount++;
break;
}
Step-6: Pulling data from details table
$query1 = $dbConnection->prepare("SELECT * FROM details WHERE DocNo=? AND DocNO_Index=?");
$query1->execute(array($dno,$index));
$rowCnt = $query1->rowCount();
while($rows1 = $query1->fetch())
{
$desg = $rows1['Item'];
$des = $rows1['Description'];
$Quantity = $rows1['Quantity'];
$Rate = $rows1['Rate'];
$per = $rows1['Per'];
$gross = $rows1['Gross'];
$SERVICE_TAX = $rows1['SERVICE'];
$SERVICE_TAX = ($SERVICE_TAX==null)? 0.0 : $SERVICE_TAX;
$SB_Tax = $rows1['SB_Tax'];
$SB_Tax = ($SB_Tax==null)? 0.0 : $SB_Tax;
$Krishi_Kalyan_Cess = $rows1['Krishi_Kalyan_Cess'];
$Krishi_Kalyan_Cess = ($Krishi_Kalyan_Cess==null)? 0.0 : $Krishi_Kalyan_Cess;
$ratetot = $ratetot + $Rate;
$subtotal = $subtotal + $gross;
if($cnt == 1 && $index > 1)

Issue is loop iteration.
My code output like this
Any suggestions on how to do this or to point me in the right direction would be greatly appreciated.

Answer 1

You're trying to re-use an active database connection. That doesn't work. You need two connections.
Specifically, you're in the process of reading a result set from a query on your connection,
$query = $dbConnection->prepare("some query");
$query->execute(array($fdcu,$tdcu));
while($rows = $query->fetch()) {
...
when you issue another query on the same $dbConnection ...
$qry = $dbConnection->prepare("another query");
$qry->execute(array($name));
You Can't Do That™ while the first query is still active. Open up and use a different connection for the queries issued from inside your loop.
