Tracking e-commerce with Google

Question

I've been asked to add Google e-commerce tracking into my site. This tracking involves inserting some javascript on your receipt page and then calling it's functions. From my asp.net receipt page, I need to call one function (_addTrans) for the transaction info and then another (_addItem) for each item on the order. An example of what they want is here

This is for a 1.1 site. Can anybody give me a jumpstart on calling these two functions from my c# code-behind? I can't imagine that I'm alone out there in needing to call Google e-commerce tracking, so I'm hopeful.

Answer 1

Probably the easiest way is to build up the required Javascript as a string with something like

StringBuilder sb = new StringBuilder()
sb.AppendLine( "<script>" );
sb.AppendLine( "var pageTracker = _gat._getTracker('UA-XXXXX-1');" );
sb.AppendLine( "pageTracker._trackPageview();" );
sb.AppendFormat( "pageTracker._addTrans('{0}','{1}','{2}','{3}','{4}','{5}','{6}','{7}' );\n", orderId, affiliation, total, tax, shipping, city, state, country );
sb.AppendFormat( "pageTracker._addItem('{0}','{1}','{2}','{3}','{4}','{5}');\n", itemNumber, sku, productName, category, price, quantity );
sb.AppendLine("pageTracker._trackTrans();");
sb.AppendLine( "</script>" );

Then register it to appear in the page with

Page.RegisterStartupScript("someKey", sb.ToString());
