# multiple a single variable

## Recommended Posts

I have a set rental amount with some variable making an equation. The final variable is the TOTAL of all the equations, i need the total of this variable

```<?php //option 1 52 weeks
\$weeklyToStudent = \$row_rsTenProp['rental_price'];
\$fourWeeksSecurityDep = 4 * \$weeklyToStudent;
\$fivetwoWeeksPayable = \$weeklyToStudent * 52;
\$fee = 184.80;
\$resFee = 250;
\$fivetwoPayIncFeedSecDep = \$fourWeeksSecurityDep + \$fivetwoWeeksPayable + \$fee;
\$initPay15Wks = \$weeklyToStudent*15;
\$initPay15WksFeeSecDep = \$initPay15Wks + \$fee + \$fourWeeksSecurityDep;
\$balanceB4MovingIn = \$initPay15WksFeeSecDep - \$resFee;
\$second14Wks = \$weeklyToStudent * 14;
\$third14Wks = \$weeklyToStudent * 14;
\$fourth9Wks = \$weeklyToStudent * 9;
\$totalPayment = \$initPay15WksFeeSecDep + \$second14Wks + \$third14Wks + \$fourth9Wks;
?>
<?php do { ?>
<tr>
<td class="table-text"><a href="customer-info.php?recordID=<?php echo \$row_rsTenProp['userid']; ?>"><?php echo \$row_rsTenProp['userid']; ?></a></td>
<td class="table-text"><?php echo \$row_rsTenProp['weeks'] / 7; ?> weeks</td>
<td class="table-text"><?php echo \$row_rsTenProp['payment_option']; ?></td>
<td class="table-text"><?php echo \$row_rsTenProp['rental_price']; ?></td>
<td class="table-text"><?php echo \$row_rsTenProp['prop_id']; ?></td>

<td class="table-text"><?php echo DoFormatCurrency(\$totalPayment, 2, ',', '.', '£ '); ?></td>
<td> </td>
<td> </td>
</tr>
<?php
} while (\$row_rsTenProp = mysql_fetch_assoc(\$rsTenProp)); ?>
```

i need to multiple the \$totalPayment to get the TOTAL of this variable

```<?php
\$totalPaymentTot = 0;
while
(\$totalPayment = (\$row_totalPayment));
\$totalPaymentTot += \$row_totalPayment;{
\$row_totalPayment;
}
echo \$totalPaymentTot;?>
```

And the problem is...?

And the problem is...?

my code is returning the value of 0 and not the total

(\$totalPayment = (\$row_totalPayment))

I think where \$row_totalPayment comes from but if you want to see if it equals \$totalPayment you need == not =

I also can't figure out what you are doing with this

```{
\$row_totalPayment;
}
```

thanks my trouble. i need to create a loop and dont know how to do it.

What are you trying to loop through? Looks like you are trying to read database records but I don't see where you open a database or select records. Do you open a database someplace else and you just didn't post that code?

hello the variable i am trying to multiply not coming from a database it is a variable resulting from other variable equations. the only variable coming from the DB is \$weeklyToStudent = \$row_rsTenProp['rental_price'];

here is all the code from the page

```<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString(\$theValue, \$theType, \$theDefinedValue = "", \$theNotDefinedValue = "")

\$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string(\$theValue) : mysql_escape_string(\$theValue);

\$grandTotal = 0;

// use a loop here

If I am understanding you correctly you are trying to total the \$totalPayment column. Try replacing this

```			  <?php
} while (\$row_rsTenProp = mysql_fetch_assoc(\$rsTenProp)); ?>
```

with this:

```			  <?php
\$grandTotal+= \$totalPayment;
} while (\$row_rsTenProp = mysql_fetch_assoc(\$rsTenProp)); ?>
```

and this

```              </tr>

</table>
```

with this:

```              </tr>
<tr><td>Grand Total:</td><td><?php echo \$grandTotal;?></td></tr>
</table>
```

If that works you will want to format the number and make the columns look pretty.

hello, thanks, this does show another figure but it isnt the total of all the \$totalPayment that are echoed out. Are we using

```\$grandTotal = 0;

// use a loop here
{
\$row['utilityAmount'];// and display the contents of the row
//\$row['SUM(utilityAmount)'];// and display the contents of the row
}
```

as this is referencing the recordset

```mysql_select_db(\$database_hostprop, \$hostprop);
\$query_rsSum = sprintf("SELECT host_editpropUtil.utilityAmount, host_editprop.prop_id, host_editpropUtil.prop_id FROM host_editpropUtil, host_editprop WHERE host_editpropUtil.prop_id = host_editprop.prop_id AND host_editprop.prop_id = %s", GetSQLValueString(\$colname_rsProperty, "text"));
```

if so this i dont think is correct because all i need to the total of the variable \$totalPayment

hang on..i know why it isnt adding up. it is also adding the \$grandTotal to the equation aswell...

all i need it the total of the \$totalPayment

to go into more detail the \$grandTotal is the total of another column for another table

```<table width="945" border="1" align="left" cellpadding="0" cellspacing="0">
<tr>
<td bgcolor="#B5EC2B" class="table-text">Utility</td>
<td bgcolor="#B5EC2B" class="table-text">Date Paid</td>

<td bgcolor="#B5EC2B"><span class="table-text">Delete</span></td>
<td bgcolor="#B5EC2B"><span class="table-text">Edit</span></td>
</tr>
<?php do { ?>
<tr>
<td class="table-text"><a href="utility-breakdown.php?recordID=<?php echo \$row_rsProperty['utilityID']; ?>"><?php echo \$row_rsProperty['utilName']; ?></a></td>
<td class="table-text"><?php echo \$row_rsProperty['utilityDatePaid']; ?></td>
<td class="table-text"><?php echo \$row_rsProperty['utilitySD']; ?></td>
<td class="table-text"><?php echo \$row_rsProperty['utilityED']; ?></td>
<td class="table-text"><?php echo DoFormatCurrency(\$row_rsProperty['utilityAmount'], 2, ',', '.', '£ '); ?></td>
<td class="table-text"><?php echo \$row_rsProperty['utilityStudAmount']; ?></td>
<td class="table-text"><a href="delete-utility.php?utilityID=<?php echo \$row_rsProperty['utilityID']; ?>">Delete </a></td>
<td class="table-text"><a href="edit-utility.php?utilityID=<?php echo \$row_rsProperty['utilityID']; ?>">Edit</a></td>
</tr>
<?php } while (\$row_rsProperty = mysql_fetch_assoc(\$rsProperty)); ?>
</table>
```

so to reiterate you code you showed me is showing the total of  \$totalPayment and the total of \$row_rsProperty['utilityAmount'] but i just need the total of \$totalPayment

i think you are making this harder than it is.

if you are trying to sum value(s) that are present inside of your display loop, just initialize the total variable to zero before the start of the loop, add the value(s) to the total inside of the loop, and use the total after the end of the loop.

specifically what values do you want to add up to make the grand total?

i have now fixed it so the issue by creating another variable

so this worked for this

\$grandTotal1 = 0;//total for Total Rent Payment

<?php
\$grandTotal1+= \$totalPayment;
} while (\$row_rsTenProp = mysql_fetch_assoc(\$rsTenProp));
?>

<?php echo DoFormatCurrency(\$grandTotal1, 2, ',', '.', '£ ', '');?>

this now give me just the total of \$totalPayment

I do have two other columns i need to make the totals of in the same way but i tried to replicate the above but didn't work

i have two more variable \$sixMultiDura and \$utility that need totals

i tried the following

```\$grandTotal1 = 0;//total for Total Rent Payment

\$sixPoundTotal = 0;//total for £6 for Room```

```			  <?php
\$grandTotal1+= \$totalPayment;
} while (\$row_rsTenProp = mysql_fetch_assoc(\$rsTenProp));
{

\$sixPoundTotal+= \$sixMultiDura;
} while (\$row_rsTenProp = mysql_fetch_assoc(\$rsTenProp));
?>
```

```                <td class="table-text"><?php echo DoFormatCurrency(\$grandTotal1, 2, ',', '.', '£ ', '');?></td>
<td class="table-text"><?php echo DoFormatCurrency(\$sixPoundTotal, 2, ',', '.', '£ ', '');?></td>```

but this is giving me the correct results for \$grandTotal1 but the \$sixPoundTotal is showing the last record in the \$sixMultiDura

your overall code, based on what you did post, has queries inside of loops inside of other loops...

that's a bad design because -

1) running queries inside of loops take a lot longer than running a single query once. you can probably write one query using JOINs and simply have one loop to do everything you are trying to do.

2) it takes more code, so it is harder for you to see what your code is doing.

without seeing what your code really is, best guess why you only get the last value is you are initializing that variable inside of the loop where that code is running and it is being set to zero every pass through the loop.

yes i really need to understand what is going on and how to clearly write a loop.

Is it where my curly brackets are going?

Its would be better if i could write just one query to handle this whole process but i am at a loss on how to do this

Does this look acceptable?, it does work but want to make sure its allowed

```\$grandTotal1+= \$totalPayment;
\$sixPoundTotal+= \$sixMultiDura;

} while (\$row_rsTenProp = mysql_fetch_assoc(\$rsTenProp)); ```
