  • FYI: how to fetch all content collections for an obj

    The manual states that collection id is necessary, but if you omit it you will in fact fetch the last (first?) collection pertaining to the given obj.

    To fetch all collections in a single pass, to eg. display them in a frontend template, a loop must be used:

    {def $count=fetch( 'content', 'collected_info_count',
    hash( 'object_id', $node.contentobject_id ) )}
    {def $collection}
    {for 0 to $count as $collectionid}
    {set $collection=fetch( 'content', 'collected_info_collection',
    hash( 'object_id', $node.contentobject_id,
    'collection_id', $collectionid ) ) }
    {* admin might have deleted this collection! *}
    {if $collection}
    {section var=collectedAttributes loop=$collection.attributes}
    ...
    {section}
    {/if}
    {/for}
