Hello,
I am trying to perform some calculations with a form but every time i try to work with checkboxes it goes wrong.
The checkboxes are beign set on value 1 in the form itselff and are being checked if there checked or not.
$verdieping = isset($_POST["verdieping"]) ? $_POST["verdieping"] : 0;
$telefoon = isset($_POST["telefoon"]) ? $_POST["telefoon"] : 0;
$netwerk = isset($_POST["netwerk"]) ? $_POST["netwerk"] : 0;
When i try to do calculations every works expect for the options with the checkboxes.
When both checkboxes (telefoon & netwerk) are selected the value should be 30.
If only one is selected the value should be 20.
But no mather what i have tried to write down it always give problem, and it always uses 20, never the value 30.
How do i solve this problem? Or suppose i am writing the syntax all wrong to lay conditions to a calculation? Any input appreciated.
$standnaam = $_SESSION["standnaam"];
$oppervlakte = $_SESSION["oppervlakte"];
$verdieping = $_SESSION["verdieping"];
$telefoon = $_SESSION["telefoon"];
$netwerk = $_SESSION["netwerk"];
if ($oppervlakte <= 10)
$tarief = 100;
if ($oppervlakte > 10 && $oppervlakte <= 20)
$tarief = 90;
if ($oppervlakte > 20)
$tarief = 80;
if($verdieping == 1)
{
$prijsVerdieping = $oppervlakte * 120;
}
else
{
$prijsVerdieping = 0;
}
if(($telefoon == 1) && ($netwerk == 1))
{
$prijsCom = 30; // never get this value, it always uses 20
}
if(($telefoon == 1) || ($netwerk == 1))
{
$prijsCom = 20;
}
$prijsOpp = $tarief * $oppervlakte; // works
$totalePrijs = $prijsOpp + $prijsVerdieping + $prijsCom; //prijsCom value is always wrong
Regards.
