Other - Issues with forms

I have a form to a shopping cart that I am developing, that adds a product to the cart using standard HTML forms. To give some feedback I open a popup window using onsubmit, and opening a new window on top with the following code

Code:

function display_alert(p,c)
	{
	var h=260;
	var w=380;
	var left = (screen.width/2)-(w/2);
	var top = (screen.height/2)-(h/2);
	var targetWin = window.open("./alert.php?prod="+p+"&coll="+c, "_blank", "location=no, status=no, toolbar=no, menubar=no, directories=no, width="+w+", height="+h+", top="+top+", left="+left);
	}

Variable P is the product ID, and C is the collection (category) ID.

I also want to pass the quantity of products ordered to this function, HOWEVER the quantity is an HTML text box within the same form, called as so:

Code:

<input type="text" name="cart_quantity" value="0" maxlength="6" size="4" />

I have tried to use the PhP $_POST to read the data from the form, but it won't read the data - presumably as I am not directly submitting the data from the form to the alert.php file.

So the question is: how can I get this cart_quantity variable either into the URL data or passed to the alert.php file?

Any help would be appreciated.

You mean something like this:

Code:

JavaScript

function display_alert(p,c)
	{
	var h=260;
	var w=380;
	var left = (screen.width/2)-(w/2);
	var top = (screen.height/2)-(h/2);
        var quantity = document.getElementById("cq").value;
	var targetWin = window.open("./alert.php?prod="+p+"&coll="+c+"&quantity="+quantity, "_blank", "location=no, status=no, toolbar=no, menubar=no, directories=no, width="+w+", height="+h+", top="+top+", left="+left);
	}

Code:

HTML

<form onsubmit="display_alert('0123','3210')">
<input id="cq" type="text" name="cart_quantity" value="0" maxlength="6" size="4" />
<input type="submit"/>
</form>
