content::item::get_content (public)

 content::item::get_content [ -revision_id revision_id ] \
    [ -item_id item_id ] -array array

Defined in packages/acs-content-repository/tcl/content-item-procs.tcl

Create a onerow datasource called content in the calling frame which contains all attributes for the revision (including inherited ones).

The datasource will contain a column called "text", representing the main content (blob) of the revision, but only if the revision has a textual mime-type.

Switches:

-revision_id (optional)

The revision whose attributes are to be retrieved

-item_id (optional)

The item_id of the corresponding item. You can provide this as an optimization. If you don't provide revision_id, you must provide item_id, and the item must have a live revision.

-array (required)

Returns:

1 on success (and set the array in the calling frame), 0 on failure
