In CF 7, the function IIF (inline IF) usage is:-
IIf(condition, string_expression1, string_expression2)
which I initially interpreted to be the equivalent of:-
<cfif condition>
<cfset result = string_expression1>
<cfelse>
<cfset result = string_expression2>
</cfif>
but when I do:-
#IIF(condition,"[a]","")#
I get an error.
On closer inspection, it turns out that IIF is really the equivalent of:-
<cfif condition>
<cfset result = Evaluate(string_expression1)>
<cfelse>
<cfset result = Evaluate(string_expression2)>
</cfif>
I've been interpreting 'string_expression' to mean an expression that
returns a string, but really means a string (or string variable) that
contains an expression.
Why is this? How do I do in-line case/switch expression?
