Hi,
I would like to know how I can get the parent of a node.

Thanks for your help

Lydie have you tried:

{$node.parent}

Sometime easy things can work ;)

I should have been more precise. I am using the treemenu and I wanted to know the parent of a node selected by this treemenu... But as far I as understood the documentation I don't think it can be done.
Am I wrong?

Slap the node until he cries and his parents are going to come. Then you can get them ;) (By night, that's likely you will only get the mother).

I don't get the problem. Once you select a node (using the treemenu or otherwise), it's displayed in the full format.

Then, with {$node.parent} on the full.tpl or the template overrided you display the parent.

What am I missing ?

The treemenu operator doesn't give you full nodes; see http://ez.no/doc/ez_publish/technical_manual/3_6/reference/template_operators/miscellaneous/treemenu

Among the things it does give you, however, is the IDs. So you can always fetch() each and every node. Can be quite a nightmare performance-wise of course.

yes that's what I add noticed. But can I with this node-id get its parent-node? don't think so...
you agree?

Hi,

assuming you're able to get the id of the node you want (from treemenu) into $currentnode

<ul>
{def $mainMenu=treemenu( $module_result.path, $module_result.node_id,                                     array('folder','info_page'), 1, 6 )}

{foreach $mainMenu as $menu}
  

{let node=fetch( 'content', 'node', hash( 'node_id', $menu.id ) )}
{$node.parent|attribute(show,1)}
{/let}
 
{/foreach}

As David said, that's going to slow the pages quite a bit.

Yes, I had noticed the same thing with the tree operator.

Anyway, as Xavier said, you can fetch in the usual way the node to get its ID.

Regarding the performances issue, I suggest that you use cache blocks in a clever way, and it should work like a charm...

You can get the ID of the parent by using

{$node.parent.node_id}

I had the same problem and it works :)
