Display multiple images on a link

Greetings,
I am trying to diplay many region images on a specific link.
I created a field in Links DB called "Region" but defined it as ENUM... but in the form display i defined it as Multi-Select and I put values like: "USA, Canada, UK...".
Now, I was to display USA flag and Canada flag next to a link.
I addeded this code in the link.html template...
However, everytime I select two values or more.. I get the image url below like: http://www.mydomain.com/flags/USACanada.gif
but I want it as you can see... to split them to USA.gif and to Canada.gif
All image flags are uploaded to flags directory to reference them on all images.
So I am missing something over here...

My question, how do I define the "Region" in Links DB to allow multiple selections, and how to break the images when they are displayed on the link inside the category.
thank you
Mark

Code:
 <%if Region%>  
<%-- loop Region --%>  
<img border="0" src="<%config.build_root_url%>/flags/<%Region%>.gif" height="14" width="25" border=0></a>  
<%-- endloop --%>  
<%endif%>

Hi,

Wrong forum ;) I've moved it for you.

I can't re3ember off the top of my head how this can be done (it needs to be done through a global). Lemme have a play, and I'll get back to you =)

Hi,

Ok, please try this.

format_multi_select

Code:
sub { 
  my @cut = split(/\n/, $_[0]);  
  use Data::Dumper; 
  my @loop; 
  foreach (@cut) { 
     push @loop, { value => $_ }; 
  } 
  return { multi_select_loop => \@loop } 
}

..then call with:

Code:
<%if Region%> 
  <%format_multi_select($Region)%> 
  <%loop multi_select_loop%> 
     <img border="0" src="<%config.build_root_url%>/flags/<%value%>.gif" height="14" width="25" border=0></a> 
   <%endloop%> 
<%endif%>

That should do the trick =)
