UseModifier

Specify attributes that can be saved in the cart along with a line item.

Synopsis

The parameter is expected to be a comma-separated list of item attribute names.

Scope

This directive is only available for use in the local (catalog.cfg) configuration file.  It will not affect any other website in any way.  This directive will not work in the global (interchange.cfg) configuration file. 

Description

This directive is used to specify the attributes that can be saved in the cart along with a line item.

Warning Interchange reserves some item attribute names for internal use and cannot be used as modifiers without the risk of significant side-effects.  Reserved names include "code", "free", "free_message", "group", "item", "quantity" and all words that start with "mv_" or "ic_".

Example

We first need to define UseModifier in the catalog.cfg file as follows (and then restart Interchange):

Then we need to add the appropriate columns (size and colour in this example) to the products table.  For example:

You'll notice that the default option for each attribute is marked with a "*" symbol.

Now all we need to display item size options is to call [loop-accessories attrname] on an Interchange page.  Let's create a sample attributes.html page:
