What's wrong with this code?

Question

i'm a new php programmer and i was working on a simple calc.. when i was testing it on localhost it works good but when i upload it to an online host it gives me (Notice: Undefined variable)

http://light557.hostbot.com/index.html

so what's wrong with it??

Answer 1

in index.php replace all with this:

<?

include ("index.html");

include ("calc.class.php");

$jm = $_POST['jm'];

$tb1 = $_POST['tb1'];

$tb2 = $_POST['tb2'];

$calc1=new calc();

if($jm=='+')

{

print $calc1->add($tb1,$tb2);

}elseif($jm=='-'){

print $calc1->minus($tb1,$tb2);

}elseif($jm=='*'){

print $calc1->mul($tb1,$tb2);

}elseif($jm=='/'){

print $calc1->div($tb1,$tb2);

}

?>

Good luck!
