This function generates a query to fetch information like (at least) last modification date (last_modified) number of entries (count) number of new entries (neue) from object_user_visits for a specific module, denoted by $type. You pass a table-name ($table_name), where the entries for the module are stored, the name of the field working as foreign-key ($range_field), the field to count the number of (new) entries ($count_field). The if-clause ($if_clause) is used to check if there are any new entries at all. With $add_fields you can specify some further fields to be fetched in the query With $add_on you can add some conditions to hold when joining object_user_visits. $object_field is the name of field in object_user_visits to join with

Parameters

string	$table_name	the name of the db-table where the entries for the module denoted by $type are stored in
string	$range_field	name of the field working as foreign-key, when joining object_user_visits
string	$count_field	field to count the (new) entries on
string	$if_clause	an sql-if-clause, used to check if there are any new entries at all
string	$type
string	$add_fields	some further fields to be fetched in the query
string	$add_on	some further conditions to hold when joining object_user_visits
string	$object_field	default: my.object_id.
string	$user_id	default: current user, user-id of user the query is built for
string	$max_field	default: chdate, denotes the field used to find out the last_modified-timestamp

Returns: string the query to operate on objects_user_visits

Here is the caller graph for this function:

getValidGroupingFields ( )

This function returns all valid fields that may be used for course grouping in "My Courses".

Returns: array All fields that may be specified for course grouping

sort_groups	(		$group_field,
		&	$groups
	)
