  • What about objects, nodes ?

    P. Renaud

    It doesn't work with nodes.
    Before :
<ul>
{foreach $all_related_albums as $related_album}
        <li>{$related_album.main_node.node_id}</li>
{/foreach}
</ul>
 
{def $unique_related_albums=$all_related_albums|unique()}
 
After :
<ul>
{foreach $unique_related_albums as $related_album}
        <li>{$related_album.main_node.node_id}</li>
{/foreach}
</ul>


    produces the following output :
    Before :
7360
7360
7360
7360
7360
4166
 
After :
7360

    You have to build an intermediate array with node id's, then use unique, then re-fetch all nodes...
