Question

OK so this is what I did: I have made web site, I was using xampp sever, I created database in phpMyAdmin, but there was a problem and I had to reinstall xampp, so with that I deleted the database(yes, i didn’t make backup:( ), so I after I install xampp, I created teh same database. But now when I run localhost/website I have a problem with some lines:

Notice: Undefined index: command in C:\xampp\htdocs\BookShop\klasici.php on line 6
and this is on line 6:

if($_REQUEST['command']=='add' && $_REQUEST['productid']>0){

I think the problem is with the session, but I haven’t changes nothing in the scripts. The session starts after the connections with the database. Thank you

But now when I changed the line above with this one:

if(isset($_REQUEST['command']) && $_REQUEST['command']=='add' && $_REQUEST['productid']>0)

{

I have another problem, I can’t not update or delete any itam in the shopping cart, below is a part of the code where I think something is wrong:

if(isset($_REQUEST['command']) && $_REQUEST['command']=='add' &&$_REQUEST['productid']>0)
    {
    remove_product(isset ($_REQUEST['pid']));
}
else if(isset($_REQUEST['command'])=='clear'){
    unset($_SESSION['cart']);
}
else if(isset($_REQUEST['command'])=='update'){
    $max=count($_SESSION['cart']);
    for($i=0;$i<$max;$i++){
        $pid=$_SESSION['cart'][$i]['productid'];
        $q=intval($_REQUEST['product'.$pid]);
        if($q>0 && $q<=999){
            $_SESSION['cart'][$i]['qty']=$q;
        }
        else{
            $msg='Some proudcts not updated!, quantity must be a number   between 1 and 999';
        }
    }
}

try changing it to

if(isset($_REQUEST[‘command’]) && $_REQUEST[‘command’]==’add’ && $_REQUEST[‘productid’]>0)
