BP_Activity_Activity::get_scope_query_sql( mixed $scope = false, array $r = array() )

Get the SQL for the ‘scope’ param in BP_Activity_Activity::get().

Description

A scope is a predetermined set of activity arguments. This method is used to grab these activity arguments and override any existing args if needed.

Can handle multiple scopes.

Parameters

$scope

(Optional) The activity scope. Accepts string or array of scopes.

Default value: false

$r

(Optional) Current activity arguments. Same as those of BP_Activity_Activity::get(), but merged with defaults.

Default value: array()

Return

(false|array) 'sql' WHERE SQL string and 'override' activity args.
