Well, unfortunately, it looks like your array isn't an array of simple
values, but an array of structures. If your array was all simple values,
and you were 100% sure that the values would not contain a common
delimiter, then you could simply do:
<cfif not listFind(arrayToList(thearray),newID)>
This simply converts the array to a list, and then does a find on it.
Since your array contains structs, you will have to loop through it.
<cfset haveIt = false>
<cflock scope="session" type="readOnly" timeout=3>
<cfloop index="x" from=1 to="#arrayLen(session.cart)#">
<cfif session.cart[x].item_id is newid>
<cfset haveIt = true>
<cfbreak>
</cfif>
</cfloop>
</cflock>
This will loop over the array and check the item_id value of each item
in the array. If it finds it, it sets a boolean to true and breaks out.
If you want to remember x, you can also do a <cfset foundItAt = x>, or
some such.
