structure of arrays sort

I would avoid using multiple arrays, which have to refer to each other - without really having a proper way to execute the plan. Structures are better for this. I created an example, which you might try out, and see if it fits your needs:

<cfscript>
session.cart.item = structnew();

// use the name also as a key
session.cart.item["john"]=structnew();
session.cart.item["john"]["name"] = "john";
session.cart.item["john"]["foodname"] = "Ribs";
session.cart.item["john"]["price"] = "13.99";
session.cart.item["john"]["comments"]="Johncomment";

session.cart.item["mary"]=structnew();
session.cart.item["mary"]["name"] = "mary";
session.cart.item["mary"]["foodname"] = "Apple";
session.cart.item["mary"]["price"] = "0.49";
session.cart.item["mary"]["comments"]="Marycomment";

session.cart.item["adam"]=structnew();
session.cart.item["adam"]["name"] = "adam";
session.cart.item["adam"]["foodname"] = "Cake";
session.cart.item["adam"]["price"] = "4.99";
session.cart.item["adam"]["comments"]="Adamcomment";

// the following line actually does all you ever wanted. arrayToList() is just a bonus
// for easy-to-understand-output in the end. More elegant solutions may exist. :-)

nameList = arrayToList(structSort(session.cart.item,"textnocase","asc","name"));
</cfscript>

<cfoutput>
<cfloop list="#nameList#" index="currentName">
#session.cart.item[currentName].name#<BR>
#session.cart.item[currentName].foodname#<BR>
#session.cart.item[currentName].price#<BR>
#session.cart.item[currentName].comments#<BR>
<HR>
</cfloop>
</cfoutput>

> All of these arrays correspond to each other, so session.cart.name[1] may be
> John,

Why would more than one person have a cart in the same session?

Sounds to me like the logic behind your data structure definition might
need revision.

Can you give some sample data, and more of an explanation of the data
structure?

It's going to be *very difficult* to apply the sorting that you want to the
structure you have, which - to me - means the structure is wrong for your
requirements.
