<cfif> problems

Thanks for the help guys, The first suggestion worked perfectly.

> <cfif #CFFILE.ServerFileExt# IS "jpg" OR "bmp" OR "gif" OR "png" OR "jpeg">

OR is a binary operator, which takes two operands:

EG: A OR B

Where each operand (A, B) must be a boolean value (or evaluate to a boolean
value).

So taking the first expression:

#CFFILE.ServerFileExt# IS "jpg" OR "bmp"

#CFFILE.ServerFileExt# IS "jpg" evaluates to an boolean value (true or
false).

"bmp" does NOT evaluate to a boolean value. Hence the error.

The reason why it works at all is that CF will "short circuit" series of
boolean expressions as soon as it gets either a definite true, or a
definite false.

So if #CFFILE.ServerFileExt# IS "jpg" evaluates to TRUE, then the entire
expression must evaluate to true, so it doesn't bother looking at any of
the other operators (which are all invalid, so just as well).

Do do what you want, you have at least two options:

1)
<cfif CFFILE.ServerFileExt IS "jpg" OR CFFILE.ServerFileExt IS "bmp" OR
CFFILE.ServerFileExt IS "gif" OR CFFILE.ServerFileExt IS "png" OR
CFFILE.ServerFileExt IS "jpeg">

Which is clearly a crappy wat of doing it.

Or you could do this:

2)

<cfif listFindNoCase("jpg,bmp,gif,png,jpeg", CFFILE.ServerFileExt)>

Clearly this is a bit more managable.

Note: in neither situation do you need the pound-signs

I don't even know what you're trying to achieve here, so I'll leave this to
someone else.

It might be an idea to read some docs, before you get too much further
along:
