everything in CF is a string! :)1) see above. ;) Really, I don't know how, there is no isString(). 2) checkout listToArray(). http://livedocs.macromedia.com/coldfusion/7/htmldocs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=ColdFusion_Documentationfile=part_cfm.htmIts been sometime since I did this, but I recall using listToArray() then looping.

Re: [ACFUG Discuss] Reading the results of a cfselect form element
To really detect for existance of a string you may want to additionally peformcfif IsSimpleValue(variable) and Trim(variable) new This will ensure that the variable is a string, number or a boolean and that the value of the variable is not empty.

RE: [ACFUG Discuss] Reading the results of a cfselect form element
Hi Leif. For those who don't recognize the name, Leif is
the manager of the Atlanta Adobe User Group.
Leif, for your need, you say that what comes in is 2 UUIDs
separated by a comma. That's called a "list" in CFML. Now, you say you want to
test if it's a string. Do you mean you want to test if it's a list? Sadly, while
there are several "decision functions" (isnumeric, isdate, etc.) there is
neither isstring, islist, nor isUUID.
Now, as for separating the the list into an array, you can
do that with listtoarray(). But if you just want be able to process the list of
values individually, you don't *need* to put them into an array. You can loop
over them, with CFLOOP LIST. You can also get at each list element using,
funnily enough, ListGetAt, or any number of other "list functions". Yes, I'm
pointing you to the docs, since there may be still other options you'd want to
consider.
Finally, though, if you might be wanting to take this list
of UUIDs (or any list) coming from a multiple select form field (or a checkbox)
and use them in SQL, you may know you could use such a comma-separated list of
values directly in SQL using the IN clause. But you may really be stumped in
that you need to get single quotes around the individual elements, to change IN
(item1, item2) to become IN ('item1','item2'). Here, CFML comes to the rescue
again with a very often missed function called ListQualify (introduced in CF
4.01, which is why I think many missed it). So assuming your form field was ids,
you could use IN (#listqualify(form.ids)#), and it would look like the last
clause above when sent to SQL.
Is any
of this close to what you needed? Sorry if I've gone off half-cocked. As always,
I hope the info might help someone. :-)

All,Sorry for the beginner's question (and my absence from

form that has a cfselect element. The multiple attribute is set to
true.When processing the form I get what I believe are two UUIDs

RE: [ACFUG Discuss] Reading the results of a cfselect form element
Just to clarify, that's a CF7-only
feature.

If you want to see if it's a string you can use:
isValid("string",varToTest)
