Couldn't get the total amount of each row - php

Question

I was having difficulty trying to get the total amount of each row with this code:
Total Sales for this day:
<b>Php <?php
function formatMoney ($number, $fractional=false) {
if ($fractional) {
$number = sprintf('%.2f', $number);
}
while (true) {
$replaced = preg_replace('/(-?\d+)(\d\d\d)/', '$1,$2', $number);
if ($replaced != $number) {
$number = $replaced;
}
else {
break;
}
}
return $number;
} // formatMoney
$result1 = mysql_query("SELECT sum(sales) FROM sales where date='$startDate'");
while($row = mysql_fetch_array($result1)) {
$rrr=$row['sum(sales)'];
echo formatMoney($rrr, true);
}
?>
But once I manually inserted the data straight to the database it appears to be working. It’s just that whenever I tried to add a data through the system, the values isn't showing at all.
Apart from it, I’m also having issue with how to refresh a column if the one next to it has placed a value that is connected to it.
Any idea? I’m getting stuck with this one.
Additional Information:
Here's the actual table.
No. of Remaining Property No. of Rented Property Rent Cost Amt. Tendered
1 1 1000 1000
1 1200
If there's a value placed in No. of Rented Property [example 1], the other column beside it No. of Remaining Property, must be refreshed and should display 0. Then the value for the Amount tendered must be=No. of Rented Property x Rent Cost.
You see the first row has values in it. And its working since I do a manual insert on the database. But The second row shows only the value for No. of Remaining Property and the rest is empty. When I tried to add value in NoRentedProperty the NoOfRemaningProperty still displays 1 and the amount was not being multiplied to the Amount Tendered.
I’ve checked my code and am quite sure that it’s all fine. But I don't understand why this is happening.

First & foremost, you should always format your code to make it easier to read. It helps you debug issues like this better & it helps others—like us—aid you in debugging issues:
function formatMoney ($number, $fractional=false) {
if ($fractional) {
$number = sprintf('%.2f', $number);
}
while (true) {
$replaced = preg_replace('/(-?\d+)(\d\d\d)/', '$1,$2', $number);
if ($replaced != $number) {
$number = $replaced;
}
else {
break;
}
}
return $number;
} // formatMoney
$query_sql = "SELECT SUM(sales) sales_total FROM sales WHERE date='$startDate'";
// echo $query_sql . '<br />';
$result1 = mysql_query($query_sql);
while ($row = mysql_fetch_array($result1)) {
$rrr = $row['sales_total'];
echo formatMoney($rrr, true);
}
The main thing I did beyond basic formatting is to return SUM(sales) as sales_total.
As far as formatting goes, I also set the actual query SQL in a variable named $query_sql and have a commented out line with echo $query_sql . '<br />'; in it. I recommend you uncomment that on your system and look at the query that is being set & test that directly in the database itself.
Given the fact you are not providing examples of what $startDate looks like—or explaining where that comes from—not much else can be done to debug this.
