Good morning,
The ListContains function does not work as you wish it to. You should use
the ListFind and ListFindNoCase functions. Here is what the docs say about
ListFind. I use this quite a bit.
ListFind
Returns the index of the first occurrence of a value within a list. Returns
0 if no value is found. The search is case-sensitive.
See also ListContains and ListFindNoCase.
Syntax
ListFind(list, value [, delimiters ])
list
List being searched.
value
Number or string that is to be found in the items of the list.
delimiters
Set of delimiters used in the list.
Examples
<!----------------------------------------------------------------------
This example shows differences between ListContains and ListFind
----------------------------------------------------------------------->
<HTML>
<HEAD>
<TITLE>ListFind/TITLE>
</HEAD>
<BODY>
<!----------------------------------------------------------------------
Create a list composed of the items one, two, three.
----------------------------------------------------------------------->
<CFSET aList="one">
<CFSET aList=ListAppend(aList, "two")>
<CFSET aList=ListAppend(aList, "three")>
<P>
Here is the list: <B><CFOUTPUT>#aList#</CFOUTPUT></B>
<P>
ListContains checks for the existence of a substring "wo" in the items in
the list.
<BR>ListContains<BR>
<CFOUTPUT>
The substring "wo" is in <B>Item #ListContains(aList, "wo")#</B> of the
list.
</CFOUTPUT>
<P>
ListFind cannot check for substrings within items; therefore, in the
following code where ListFind in used in place of ListContains, it will
not find the substring "wo" in the list.
<BR>ListFind<BR>
<CFOUTPUT>
The substring "wo" is in <b>Item #ListFind(aList, "wo")#</b> of the list.
</CFOUTPUT>
<P>
However, if you specify the entire string <B>two</B>, both ListContains
and ListFind will find it in the second item in the list.
<BR>ListContains<BR>
<CFOUTPUT>
The string "two" is in <b>Item #ListContains(aList, "two")#</b> of the
list.
</CFOUTPUT>
<BR>ListFind<BR>
<CFOUTPUT>
The string "two" is in <b>Item #ListFind(aList, "two")#</b> of the list.
</CFOUTPUT>
</BODY>

Subject: Listcontains question
Hi
I have the following piece of code that checks to see if a user can see a
specific pageid or not. Unfortunately it is not doing the job as I have a
list that looks something like this:
4,14,3,2,8,44
If the user is allowed to see page 4, then he would be able to see all pages
that contains a 4, so it does not work correctly.
<cfif listcontains(newlist, "#pageid#")>
<cfinclude template=#page#>
<cfelse>
<cfoutput>
#application.securityerror#
</cfoutput>
</cfif>
Regards
Carlo
