Help with shopping cart?

[lelyea]

I am now at the shopping cart stage of my final project for my PHP class and am having a problem involving a url encoded string.

Here is my string:

echo "<a href='cart.php?action=add_item&.'$isbn'.&qty=1'>Add Item To Shopping Cart</a>";

and here is relevant code from cart.php:

switch($GET["action"])
{
case "add_item":
{
AddItem($GET["id"], $GET["qty"]);
ShowCart();
break;
}
case "update_item":
{
UpdateItem($GET["id"], $GET["qty"]);
ShowCart();
break;
}
case "remove_item":
{
RemoveItem($GET["id"]);
ShowCart();
break;
}
default:
{
ShowCart();
}
}

I end up with zilch being passed to cart.php.

As always, help is appreciated - up front!

Thanks

Looks like you have a confusion of strings in you html link. I believe you mean't to use double quotes rather than single quotes like so:

echo "<a href='cart.php?action=add_item&".$isbn."&qty=1'>Add Item To Shopping Cart</a>";

It should work now...

Just thought I'd add in relation to the above answer that the OP had the two . in the wrong sides of the quotes as well. scross had this fixed in their answer.

Also, when posting PHP code, please use the board's [PHP][/PHP] bbcode tags - they make the code much, much easier to read (as well as aiding the diagnosis of syntax errors). You should edit your post now and add these bbcode tags to help others in reading/analyzing your code.
