Another Moodle cartoon, expressing my discovery that a function for returning data about users can return fields, such as Skype ID, that the function for creating users can never accept. (See Why is the argument to core_user_create_users different from the result of core_user_get_users_by_id? .)
The orange Michelin-man-like Moodle figure is disdainfully pointing at a whiteboard. He is lecturing. The whiteboard shows the specification for the inputs to the Moodle core function
core_user_create_users, and the outputs to the core function
core_user_get_users_by_id. The outputs contain many fields that are not in the list of inputs, such as Skype and Yahoo IDs.
