Re: (beginner) Coldfusion: variable to change language

[Ian Skinner <iskinner@xxxxxxxxxxx>]

<cfparam name="url.language" default="eng">
<!--- Defines a default for the url language variable if one does not 
exist. --->

<cfset variables.lang = url.language>
<!--- Transfers the value of the url scope language variable to the 
local variables scope variable. --->
<!--- NOTE: This is rather redundant, since the URL scope and the 
Variables Scope will have the same life in this scenario.  Thus 
url.language could be used anywhere variables.language is used.  This 
would make more sense if the value was stored in a persistent scope such 
as session. --->

 <cfif isdefined("lang") and lang eq "eng">
 header html here
 </cfif>

 <cfif isdefined("lang") and lang eq "swe">
 header html here (in swedish)
 </cfif>

<!--- I would write this has a case or at least an if-elseif so to cut 
down unnecessary processing. --->
<cfswitch expression="#variables.lang#">
  <cfcase value="eng">
    header html here
  </cfcase>
  <cfcase value="swe">
    header html here (in swedish)
  </cfcase>
</cfswitch>

OR

<cfif lang eq "eng">
  header html here
<cfelseif lang eq "swe">
  header html here (in swedish)
</cfif>

ALSO note with the <cfparam...> tag to provide a default the isDefined() 
or prefered structKeyExists() function is unnecessary.
