function aggregator_feed_items_load

Loads and optionally filters feed items.

Parameters

$type: The type of filter for the items. Possible values are:

• sum: No filtering.
• source: Filter the feed items, limiting the result to items from a single source.
• category: Filter the feed items by category.

$data: Feed or category data used for filtering. The type and value of $data depends on $type:

• source: $data is an object with $data->fid identifying the feed used to as filter.
• category: $data is an array with $data['cid'] being the category id to filter on.

The $data parameter is not used when $type is 'sum'.

Return value

An array of the feed items.
