Hi,
I'm creating a very simple script (or so I thought) in which a user can select items from a form, the script will take the number values of those items and do two things: display the names of the items selected, and add the items together and give the user a total price including taxes.
In my form, I use the following syntax:
<input type="checkbox" name="hit_955" value="14.72">
The form is then sent using the POST method.
I then retrieve the values using the following syntax:
$hit_955 = $HTTP_POST_VARS["hit_955"];
All together there are 14 items a user can choose - for testing purposes, I chose all items. The script would only display and add the first, second, and tenth items. All others are ignored.
Here is the script - its broken into three parts - the first part is collecting the information - the second part is doing the actual math - and the third part displays the item names that the user chose. Does anyone see anything wrong with this script, or have a possible reason why its only choosing 3 out of 14 items to work with?
PART ONE:
<?
$SubTotal = 0;
$FormattedSubTotal = 0;
$Total = 0;
$FormattedTotal = 0;
$PST = 1.08;
$GST = 1.07;
$CalcPST = 0;
$CalcGST = 0;
$FormattedPST = 0;
$FormattedGST = 0;
$nokia252c = 0;
$battery = 0;
$hit_955 = 0;
$hit_965 = 0;
$nok_cbl_7 = 0;
$nok_lch_6rpd = 0;
$nok_cgh10 = 0;
$nok_lch9 = 0;
$belt_252 = 0;
$nokia_0261670 = 0;
$s_nok_0261669 = 0;
$nok_mbc_3k = 0;
$nok_cark_89 = 0;
$nok_cark_90 = 0;
$nokia252c = $HTTP_POST_VARS["nokia252c"];
$battery = $HTTP_POST_VARS["battery"];
$hit_955 = $HTTP_POST_VARS["hit_955"];
$hit_965 = $HTTP_POST_VARS["hit_965"];
$nok_cbl_7 = $HTTP_POST_VARS["nok_cbl_7"];
$nok_lch_6rpd = $HTTP_POST_VARS["nok_lch_6rpd"];
$nok_cgh10 = $HTTP_POST_VARS["nok_cgh10"];
$nok_lch9 = $HTTP_POST_VARS["nok_lch9"];
$belt_252 = $HTTP_POST_VARS["belt_252"];
$nokia_0261670 = $HTTP_POST_VARS["nokia_0261670"];
$s_nok_0261669 = $HTTP_POST_VARS["s_nok_0261669"];
$nok_mbc_3k = $HTTP_POST_VARS["nok_mbc_3k"];
$nok_cark_89 = $HTTP_POST_VARS["nok_cark_89"];
$nok_cark_90 = $HTTP_POST_VARS["nok_cark_90"];
?>
PART TWO:
<?
$SubTotal = $nokia252c + $battery + $hit_955 + $hit_965 + $nok_cbl_7 + $nok_lch_6rpd + $nok_cgh10 + $nok_lch9 + $belt_252 + $nokia_0261670 + $s_nok_0261669 + $nok_mbc_3k + $nok_cark_89 + $nok_cark_90;
$CalcPST = ($SubTotal * $PST) - $SubTotal;
$CalcGST = ($SubTotal * $GST) - $SubTotal;
$Total = $SubTotal + $CalcPST + $CalcGST;
$FormattedSubTotal = number_format($SubTotal, 2);
$FormattedPST = number_format($CalcPST, 2);
$FormattedGST = number_format($CalcGST, 2);
$FormattedTotal = number_format($Total, 2);
?>
PART THREE:
<? if ($nokia252c > 0)
{
echo "Nokia 252c";
}
else
{
echo "";
} ?>
Thanks
