static core_message\helper::search_get_user_details	(	\stdClass	$user,

static

Returns user details for a user, if they are visible to the current user in the message search.

This method checks the visibility of a user specifically for the purpose of inclusion in the message search results. Visibility depends on the site-wide messaging setting 'messagingallusers': If enabled, visibility depends only on the core notion of visibility; a visible site or course profile. If disabled, visibility requires that the user be sharing a course with the searching user, and have a visible profile there. The current user is always returned.

You can use the $userfields parameter to reduce the amount of a user record that is required by the method. The minimum user fields are:

id
deleted
all potential fullname fields

Parameters

stdClass	$user
array	$userfields	An array of userfields to be returned, the values must be a subset of user_get_default_fields (optional)

Return values

array the array of userdetails, if visible, or an empty array otherwise.
