Subject finding the length of an array
Date Thu, 18 Aug 2005 13:05:46 GMT
after reading through Jean Francois Chamard's excellent technique for
finding the last item in an array with Velocity (posted 22/07/2005), I've
been trying to implement this for a array of HTML links.

however, I've been encountering problems using the length method which is
used there: it's just failing silently (haven't got access to the velocity
log for this at present, unfortunately).

here is the code I am using:

## a load of links, with text + hrefs etc held in their own array
#set ( $link1 = ["link 1","this is link one",""] )
#set ( $link2 = ["link 2","this is link two","http://link.two"] )
#set ( $link3 = ["link 3","this is link three","http://link.three"] )
#set ( $link4 = ["link 4","this is link four","http://link.four"] )
#set ( $link5 = ["link 5","this is link five","http://link.five"] )
#set ( $link6 = ["link 6","this is link six","http://link.six"] )

## stick alll those arrays into an array
#set ( $linkMultiArray = [$link1,$link2,$link3,$link4,$link5,$link6] )

## do loop to produce output
#set( $len = $linkMultiArray.length )
#foreach($link in $linkMultiArray)
    #set( $velocityCount2 = $velocityCount + 1 )
    #set( $len2 = $len - 1 )
    $link.get(0)#if($len2 == $velocityCount) and#elseif($len >
$velocityCount2), #end

the desired result:
link 1, link 2, link 3, link 4, link 5 and link 6

what I'm getting:
link 1link 2link 3link 4link 5link 6

Any comments/suggestions/help/answers gratefully received!
