Hi, I need to fetch a list of eZContentObjectTreeNode
fetch( content, list, hash( parent_node_id, $node_id, ... ) ) But, I need to fetch only distinct eZContentObject. So, the main_node_only parameter remove too much nodes inside the subtree. So I can't filter the list after the request cause I need to build a page system and to set the OFFSET and LIMIT parameters. I looking at the extended_attribute_filter, but it doesn't seem to allow a DISCTINCT clause. Is there anyone know how to do this ? Thanks in advance, Fabien.

Hello Fabien, Well, the main_node_only parameter should do what you are willing to do. What do you exactly mean by : "So, the main_node_only parameter remove too much nodes inside the subtree." Cheers,

Hi Nicolas, The main_node_only parameter only retrieve the main location (or main node, as you want).The main_node_only parameter doesn't retrieve the content objects which the main node is outside the sub-tree. I need to fetch all content objects in the sub-tree. But without the main_node_only parameter the query probably fetch same content object many times (cause of different locations in the sub-tree). I need: one content object → one node. Thanks for you help Nicolas. Cheers, Fabien.

Ok, got it. I'd go for a custom fetch function here, overriding the content/list one (to preserve the many useful parameters ), going as follows :
- Run the content/list fetch function from PHP ( use the magic eZFunctionHandler::execute(...) ) with 'as_object' [1] set to false --> performances performances.
- Loop over the results, building an intermediate associative array, with contentobject IDs as keys. Will automatically filter out duplicates object IDs by overriding the keys.
- Return the array values, or replace them by fetched eZContentObjectTreeNode objects, on a one-by-one basis.
Hope it helps !

Hi Nicolas, It works fine!
- A custom operator,
- The request to fetch all nodes ( with the useful eZFunctionHandler::execute ),
- The loop to filter duplicates content object,
- An array slice to apply the offset and limit,
- And return the clean list.
Good job! Thanks, Fabien.

{def $beer_count = fetch( 'beer', 'count',
hash( 'from', 'Fabien',
'to', 'Nicolas',
'where', 'at the ez conference in Berlin'
))}
{$beer_count|attribute( 'show', 1, false() )}
{*
Displays :
beer_count (1)
*}:) The eZ Conference : http://share.ez.no/blogs/ez/ez-conference-2010-in-berlin-next-june
See you there !
Cheers,
