How to check for a variable value that can have null values too ... 1

[msng]

I have defined as follows:

<cfparam name="URL.cust_name_hold" default="">

Later on, if I have to check if URL.cust_name_hold has a value or not, how will I write the IF statement?

Please let me know. Thanks.

you can do

<cfif Len(URL.cust_name_hold)>
variable has a value
<cfelse>
variable is empty
</cfif>

<cfif URL.cust_name_hold is not "">

or.. and this is the preferred, faster method:

<cfif len(URL.cust_name_hold)>

If you want to make sure the value is not just spaces.. like " " or " "

<cfif len(trim(URL.cust_name_hold))>
