Hello,
I've just been trying to figure out the most efficent way to check for a
passed (form or url) variables pesence and value. The code I've been using
is:
<CFIF (IsDefined("ATTRIBUTES.Request_time") IS "No") OR
(Trim(ATTRIBUTES.Request_time) IS "")>
Request_time is not defined
<CFELSE>
Request_time is defined
</CFIF>
But is this the best way, it must be a common problem. I also thought about
using :
<CFPARAM NAME="ATTRIBUTES.Request_Time" DEFAULT="0">
<CFIF Trim(RequestTime) IS "0">
Request_time is not defined
<CFELSE>
Request_time is defined
</CFIF>
but that doesn't work as it doesn't apply the value 0 if Request_time is
passed but not defined... So is the first method the best?
Thanks
Ben
