Alternative to several if/then statements?

[frosco]

I know this exists, I just don't know what it's called so I can search for it. (Newbie, can you tell?)

I have several if/then statements that I want to combine. What is that called? Example...this is part of my code (and there's more!):

<%
if page="links" then%>
<!--#include file="links.htm"-->
<%end if
%>
<%
if page="homepg" then%>
<!--#include file="homepg.htm"-->
<%end if
%>
<%
if page="id" then%>
<!--#include file="id.htm"-->
<%end if
%>

I know there's a way to tighten this up. Now, EVERY TIME I post here, I end up finding my answer within a few minutes...regardless of how much time I've already spent looking. We'll see what happens.

But if you beat me to it, would you please tell me what that's called?

THANKS!

I believe your looking for 'case' statement...

I tried this ages ago, and it wasn't fun. I just gave up in the end, using pre-defined links.

In the end I created a links.inc, then stuck this in:

<%

dim home
home = "http://www.domain.com"
dim products
products = "http://www.domain.com/products/"

%>
then in the page you have added this to, just call a link like this <a href="<%= home %>">Home</a>

this means you do not have to change your whole site when you change your links, also you can use a database, but pointless..

<%

if page="links" then%>
<!--#include file="links.htm"-->
<%end if
%>
<%
if page="homepg" then%>
<!--#include file="homepg.htm"-->
<%end if
%>
<%
if page="id" then%>
<!--#include file="id.htm"-->
<%end if
%>

All the code in all the files would get included here (so for example you wouldn't be allowed to dim the same variables outside functions in 2 different included files) but only the code within the appropriate If Then would get acted upon.

For dynamic includes you may want to look into Server.Execute like this:

And in general don't forget about this possible structure for code:

If blah1 Then

...

Elseif blah2 Then

...

Elseif blah3 Then

...

Else

...

End If

You want something like the following:

<%
Select Case somevariable
    Case 1
        Do something
    Case 2
        Do something else
    Case 3
        Do something entirely different
    Case Else
        Do something if nothing matches any of the above
End Select
%>

The "Case Else" is completely optional.

You can use any variable, request.form or request.querystring item in place of "somevariable".

Also, where you see "Case 1, 2, 3", the 1, 2 and 3 can be any string or number format such as "hello" or 10.
