Cart quantity/items variable

[Richardpixel]

Hi,

I can't seem to find a variable for cart quantity/no. of items.

I'm basically just trying to test if there is anything in the users shopping cart and display something appropriately.

Anyone know of a variable I can use to test on?

<script language="javascript" type="text/javascript">
<!--
document.write(getCartItem(3));
// -->
</script>

I use this effect on http://www.bumpbirthandbeyond.co.uk/ which adds a toy to the cart when something is added.

The code I use is

<script language="javascript" type="text/javascript">
var nItems = Number(getCartItem(3));
var nValue = getCartItem(1);
if (nItems == 0) {
document.write ("<div id=\"cartEMPTY\"><img src=\"bbb-cart-empty.gif\"/></div>");
} 
</script>

HTH

Thank you so much. Works like a treat!

I have also added an else statement:

<script language="javascript" type="text/javascript">
var nItems = Number(getCartItem(3));
var nValue = getCartItem(1);
if (nItems == 0) {
document.write ("<div id=\"cart-empty\" class=\"floatr\"></div>");
}
else {
document.write ("<div id=\"cart-full\" class=\"floatr\"></div>");
}
</script>

Good one Jonty - I thought this was going to be more complex and perhaps directly involve perl and cookies etc.
