ListDeleteValue - Remove Part of List

coldfusion, coldfusion-8

Solution

You need to use `ListDeleteAt()` and also need to find the position of the item in the list using `ListFind()` This code works below

Note: You don't need to use `"##"` when you're setting a variable to another variable

<cfset userssigned = 'userx:usery:userz' />
<cfset session.user_id = 'userz' />

<cfset curlist = userssigned />
<cfset ud = session.user_id />

<cfoutput>
 #curlist#<br><br>
 #ud#<br>
 <cfset newlist = ListDeleteAt( curlist, ListFind(userssigned,ud,":"), ":") />
 #newlist# - should delete userz? end up as userx:usery
</cfoutput>

Problem

Trying to remove a userid from a given list. Can't seem to crack it... Errors on the removal at the ListDeleteValue - something I'm missing. On CF8. ``` <cfset curlist = "#userssigned#"> - say userx:usery:userz <cfset ud = "#session.user_id#"> - say userz <cfoutput> #curlist# <br> <br> #ud# <br> <cfset newlist = ListDeleteValue( curlist, "#ud#", ":") /> #newlist# - should delete userz? end up as userx:usery </cfoutput> ```
