Gossamer Forum: Products: Gossamer Links: Development, Plugins and Globals: Variable scope in template <%loop%> tag

I want to place a category title (title_linked tag) above a search.cgi result but ONLY if the category has changed, i.e. every link searched is associated with a category using the title_linked variable in the link_loop_results. However, I'm not sure how to check if it has changed because you need to compare with the previous/next iteration of the loop.

Here's what I got so far but it doesn't seem to work exactly...

Code:


 <%loop link_results_loop%> 
   <%if first%>  <%-- set up the opening table --%>  
     <TABLE>  
     <TR>  
   <%endif%>  



<%--  

Check if link is in a new category, if so display it  

--%> 



<%if prevcat%> 
   <%if prevcat != $title_linked%> 
   <TR><TD><span class="hi_orange"><%title_linked%></span><br></TD></TR> 
   <%endif%> 
<%else%> 
<%set prevcat = $title_linked%> 

<TR><TD><span class="hi_orange"><%title_linked%></span><br></TD></TR> 
<%endif%> 



<%-- Pull Individual Link Format --%> 
   <TD> 
<%include linkGallery.html%> 
   </TD>  
   <%ifnot row_num % 4%>  <%-- close the row --%>  
      </TR>  
   <%endif%>  

   <%if last%>  <%-- close the table --%>   
     <%if row_num % 4 eq 1%>  <%-- balance the trailing rows --%>  
      <TD></TD><TD></TD>  
     <%endif%>  
     <%if row_num % 4 eq 2 %>  <%-- balance the trailing rows --%>  
       <TD></TD>  
     <%endif%>  
     </tr>  
     </TABLE>  
   <%endif%>  

<%endloop%>
