Using the shopping cart tag with IBM Digital Analytics

If your site is integrated with IBM Digital Analytics, formerly known as Coremetrics Analytics, you can use the default implementation of the <cm:cart /> tag that WebSphere Commerce provides. The <cm:cart /> tag generates the following IBM Digital Analytics tag: cmCreateShopAction5Tag.

Tag placement in store pages

Include the <cm:cart /> tag in the shopping cart page. In the page, place the <cm:cart /> tag before the <cm:pageview /> tag.

You must also include the tag library in the JSP file before the main page content by using the following code:


<%@ taglib uri="http://commerce.ibm.com/coremetrics" prefix="cm" %>

The data that the <cm:cart /> tag generates is different depending on which IBM Digital Analytics tag library type your store uses. To see examples, go to one of the following sections in the following topic:

Examples of tag usage: for the standard IBM Digital Analytics library
Examples of tag usage: for the custom IBM Digital Analytics library

Example of tag usage and output for IBM Digital Data Exchange (DDX)

If your WebSphere Commerce store is integrated with DDX to simplify collecting analytics data, the <cm:cart /> tag generates data into the digitalData JavaScript object that is sent to DDX. DDX can then relay the data to IBM Digital Analytics. The generated data that in this JavaScript object can look like the following output:

digitalData.cart.item[0] = { 
  productInfo:{productID: 'MCL008_0802', productName: 'Albini Dark Gray Wool Suit'},
  quantity: '1', price: '977.97', currency: 'USD', 
  category:{primaryCategory: '3074457345616676683', virtualCategory: ''}, 
  attributes:{exploreAttributes: '', extraFields: ''}};
  cmSetupOther({"cm_currencyCode":"USD"});
  {}
digitalData.cart.item[1] = { 
  productInfo:{productID: 'CAC024_2401', productName: 'Widescreen LCD Monitor'}, 
  quantity: '1', price: '132.03', currency: 'USD', 
  category:{primaryCategory: '3074457345616676695', virtualCategory: ''},
  attributes:{exploreAttributes: '', extraFields: ''}};
  cmSetupOther({"cm_currencyCode":"USD"});

For more information about integrating with DDX, see IBM Digital Data Exchange integration.

Examples of tag usage: for the standard IBM Digital Analytics library

The

<cm:cart
/>

tag generates the following IBM Digital Analytics data tag:

cmCreateShopAction5Tag(productID, productName, productQuantity, productPrice, 
categoryID, attributes, extraFields)

Example 1:

To pass basic data to IBM Digital Analytics about each item in a customer's shopping cart:


Include tag in your store page like the following code:	If your store uses data beans and URL commands for order runtime functions, use the `databean` parameter: `<cm:cart databean="${order_OrderDataBean}" />` If your store uses web services for order runtime functions, use the `orderType` parameter: `<cm:cart orderType="${order}" />`
Example of IBM Digital Analytics data tag generated:	`cmCreateShopAction5Tag("AS-01", "AromaStar Deluxe", "1.0", "71.05", "10574");`

Example 2:

To pass IBM Digital Analytics Explore attributes to the IBM Digital Analytics cmCreateShopAction5Tag that are the same for all items in the shopping cart, use the extraparms parameter (position 2):

Include tag in your store page like the following code:

If your store uses data beans and URL commands for order runtime functions, use the following parameters:

<cm:cart databean="${order_OrderDataBean}" 
extraparms="null, attr1-_-attr2-_-attr3" />

If your store uses web services for order runtime functions, use the following parameters:

<cm:cart orderType="${order}" 
extraparms="null, attr1-_-attr2-_-attr3" />

Example of IBM Digital Analytics data tags generated:

cmCreateShopAction5Tag("AS-01", "AromaStar Deluxe", "1.0", "71.05", 
"10574", "attr1-_-attr2-_-attr3");
cmCreateShopAction5Tag("TASI-01", "5-Piece Silverware Set", "1.0", "24.01", 
"10564", "attr1-_-attr2-_-attr3");

For details about each parameter in the IBM Digital Analytics data tag, see the documentation that is provided by IBM Digital Analytics.

Examples of tag usage: for the custom IBM Digital Analytics library

The

<cm:cart
/>

tag generates the following IBM Digital Analytics data tag:

cmCreateShopAction5Tag(productId, productName, productQuantity, productPrice, 
categoryId, store_id, currency, masterItemCategory, catIDoverride, attributes)

Example 1:

To pass basic data to IBM Digital Analytics about each item in a customer's shopping cart:


Include tag in your store page like the following code:	If your store uses data beans and URL commands for order runtime functions, use the `databean` parameter: `<cm:cart databean="${order_OrderDataBean}" />` If your store uses web services for order runtime functions, use the `orderType` parameter: `<cm:cart orderType="${order}" />`
Example of IBM Digital Analytics data tag generated:	`cmCreateShopAction5Tag("AS-01", "AromaStar Deluxe", "1.0", "71.99", "10124", "10101", "USD", "10124");`

Note: The examples in this topic use the simplified syntax for specifying extraparms values. If your store is not on WebSphere Commerce Version 7 Feature Pack 3 or later, you must specify the values using properly escaped JavaScript:

Simplified syntax example: extraparms="value1-_-value2,value3-_-value4"
Properly escaped JavaScript example: extraparms="\"value1-_-value2\",\"value3-_-value4\""

If any of your extraparms values are JavaScript variables, see the syntax rules explained in Syntax for passing JavaScript variables as extra parameters.

Example 2:


Include tag in your store page like the following code:	If your store uses data beans and URL commands for order runtime functions, use the following parameters: `<cm:cart databean="${order_OrderDataBean}" extraparms="null, attr1-_-attr2-_-attr3" />` If your store uses web services for order runtime functions, use the following parameters: `<cm:cart orderType="${order}" extraparms="null, attr1-_-attr2-_-attr3" />`
Example of IBM Digital Analytics data tag generated:	`cmCreateShopAction5Tag("AS-01", "AromaStar Deluxe", "1.0", "71.99", "10124", "10101", "USD", "10124", null, "attr1-_-attr2-_-attr3");`
