TAG REFERENCE

<cart:add>

Adds an a item to the current cart. You can specify the item properties as attributes in the tag itself:

<cart:add
    description="My New Part"
    id="11111111-1111-1111-1111-111111111111"
    sku="1234"
    quantity="1"
    price="1.23"
/>

or you can add them as child elements:

<cart:add>
    <cart:description>My New Part</cart:description>
    <cart:id>11111111-1111-1111-1111-111111111111</cart:id>
    <cart:sku>1234</cart:sku>
    <cart:quantity>1</cart:quantity>
    <cart:price>1.23</cart:price>
</cart:add>

or any combination of the two:

<cart:add quantity="1">
    <cart:description>My New Part</cart:description>
    <cart:id>11111111-1111-1111-1111-111111111111</cart:id>
    <cart:sku>1234</cart:sku>
    <cart:price>1.23</cart:price>
</cart:add>
