That is very similar to the way I do it.
I think you can skip the query loop by using valuelist():
cfset variables.selected_features = valuelist(q_selected_features.
feature_id)
Note you can simplify that cfif statement in the checkbox down to:
cfif listfind(variables.selected_features, feature_id)
The above code *should* work the same as your code just a little simpler.

And I have a list of features assigned to a specific item.
I want to print out the generic features with checkboxes
next to them.
If the item in question has been assigned one of the
features, I would like the checkbox for that feature to be
checked.
In the input tag for the checkbox, what function should I be
using to compare the feature_id to the query results?
This has taken me all day, but I think the break at lunch
helped clear things up for me.
After querying the selected features, create an empty
variable (it will eventually hold the list of features):
cfset variables.selected_features =
Using cfoutput, add each of the selected features to the list:
cfoutput query=q_selected_features
cfset variables.selected_features =
listappend(variables.selected_features,#q_selected_features.feature_id#)
/cfoutput
If you output variables.selected_features, you'll see a
comma delimited list of feature id's.
While ouputting the complete list of possible features, you
add a cfif statement to the checkboxes:
input
name=footnote
type=checkbox
value=
cfif listfind(variables.selected_features, #feature_id#)
IS NOT 0
checked=checked
/cfif
/
variables.selected_features is our list of currently
selected features. feature_id comes from the full list of
possible features.
This *is* the easy way to solve this, right?
