Accessing form fields with [brackets] in the name

Wondering if anyone has ideas for accessing form field values when the fieldnames include brackets like the ones in the cfdump of a form post shown below (it’s a MailChimp webhook)?

When I try to access the values using #form.data[list_id]# for example, I get a ColdFusion error, I’m guessing because it thinks I’m trying to access an array element. Any help appreciated.

struct
DATA[LIST_ID]	000000000
DATA[NEW_EMAIL]	foo@bar.com
DATA[NEW_ID]	000000000
DATA[OLD_EMAIL]	foo@bar.com
FIELDNAMES	TYPE,FIRED_AT,DATA[NEW_ID],DATA[NEW_EMAIL],DATA[OLD_EMAIL],DATA[LIST_ID]
FIRED_AT	2010-03-08 17:49:09
TEMPID	[empty string]
TYPE	upemail

Correct answer Adam Cameron.

One can access struct members either via dot-noation if the keys are "valid variable names", or via bracket notation, eg:

myStruct["myKey"]

Using bracket notation does not have the valid-variable-name restrictions that dot notation has.

So in the case of my example the correct syntax would be

#form["data[list_id]"]#

correct?

Thanks,
