hi all,

i'm using this:

<cfloop list="#client.recentlyViewed#" index="ListItem">
<cfset prodID = listFirst(listItem,"|")>
<cfset prodName = listRest(listItem, "|")>

  <cfoutput >
  #prodName# - #prodID# - #ListItem#<br />
 </cfoutput>
 
</cfloop>

to output some data but i only want to output 5 rows of data. i thought maybe adding maxrows="5" might do it but that throws an error.

any know what i need to do?

thanks

There's no simple way to limit a "list" loop.  Either add a counter and break out of the loop after 5 items

<cfset counter = 1>
<cfloop list="#client.recentlyViewed#" index="ListItem">
   ... output the item ....
  <cfset counter = counter + 1>
  <cfif counter gte 5>
          <cfbreak>
  </cfif>
</cfloop>

.. OR use a from/to loop.

<cfset loopLength = Min(ListLen(client.recentlyViewed), 5)>
<cfloop from="1" to="#loopLength#" index="i">
<cfset ListItem = ListGetAt(client.recentlyViewed,i)>
<cfset prodID = listFirst(listItem,"|")>
<cfset prodName = listRest(listItem, "|")>

<cfoutput >
#prodName# - #prodID# - #ListItem#<br />
</cfoutput>
 
</cfloop>

@bede123 - I was just typing up a from/to example when I saw js_vaughan's post.  Both work, but personally I'd use js_vaughan's code. It's simpler.
