Parameters

$field: The field the action is being performed on.

$item: An array, keyed by column, of the data stored for this item in this field.

$formatter: The name of the formatter being used to display the field.

$node: The node object, for context. Will be NULL in some cases. Warning: when displaying field retrieved by Views, $node will not be a "full-fledged" node object, but an object containg the data returned by the Views query (at least nid, vid, changed)

Return value

An HTML string containing the formatted item.

In a multiple-value field scenario, this function will be called once per value currently stored in the field. This function is also used as the handler for viewing a field in a views.module tabular listing.
