cfif

[RyanG24]

Hi i have the following cfif,

<cfif IsDefined("form.EXH_Program_#currRow#")>

i need to change it to
<cfif ("form.EXH_Program_#currRow#") EQ "X">

but this is not working any ideas why?

Well the string "form.EXH_Program_#currRow#" (which is what it is: just a
string) will never equal "x" will it?

You probably mean:
form["EXH_Program_#currRow#"] eq "x"

Also, if you need to do the same thing for variables not in a collection (i.e. the form collection in this case), you can always use the Evaluate() function:

e.g.
Evaluate("form.EXH_Program_#currRow#")
or
Evaluate("form.EXH_Program_" & currRow)

True, but, using array notation as per Adam's post is more efficient.

Also, using array notation is not a massive security whole as evaluating data that is provided by users is basically madness. In addition virtually every ariable in CF is in a structure(collection) so you never need to use evaluate(), if you are using it then you are doing something wrong, the only time I can think you couldn't avoid using it is to use dynamic method names.
