Cold Fusion Build-In Variable

Question

Good Day:
Tx in advance for answering my question....
I'm a new user in CF. Looking for some siple output in
CLIENT.variable. For instance, I just would like code a simple
output of CLIENT.LastVisit
All the example I searched give me something:
<cfoutput>
Welcome back!!! Your last
visit was on #DateFormat(Client.LastVisit)#.
</cfoutput>
which return me null. To sucessfully use it, I somehow
believe i need to use it together with the <cfaplication>.
May I have something as simple as possible just to see the result?
On top of that, if I were to futher use the CLIENT.CFID, I
believe i should use the <cfset> to set it? How? Pls reply me
something as simple as possible like:
<cfset CLIENT.CFID>???
<cfoutput>#CLIENT.CFID</cfoutput>
On the CF (or I'm acceing throuhg Dreamweaver), I can find a
simple help example for those coding. I belive it should have. In
future, how and hwere is the best way to just view some coding
example whenever I encounter problem? I even when to the CF Admin -
description there is good but no example, some on the Code Panel...
tx!

Hello, it would be possible to generate a variable like that,
using client management.
First, you would need to either turn on client management in
your administrator, or make a file called application.cfm, and put
it in main website directory. Ad one line in there that says:
clientmanagement="yes"
and then save the file.
Then when you make your page, you need to set a default as
today by using the follow code:
<CFPARAM name="client.LastVisit" default="unknown">
<cfif client.LastVisit IS 'unknown'>
<cfset client.LastVisit = #DateFormat(Now(),
"MM/DD/YYYY")#
</cfif>
Then, you can use the #client.LastVisit# variable throughout
your page, then at the end of your page, you will want to update it
to todays date if it already had a date, with the following code:
<cfset client.LastVisit = #DateFormat(Now(),
"MM/DD/YYYY")#
Make sure its used at the end of your page, and keep in mind
that if you use the cflocation tag, the client variables that you
try to set on that page will not save properly, so dont use
cflocation with pages that have client variables to be safe.
Have fun!
