This files describes API changes in /portfolio/ portfolio system, information provided here is intended especially for developers. === 2.4 === The set_callback_options function's third parameter has been changed from a file path to the component name - see MDL-33791. However, if any existing code passes a file path Moodle will attempt to obtain the component name from the file path provided. Also, the callback class should be located in the module's locallib.php file. Example of change: This: $button->set_callback_options('assignment_portfolio_caller', array('id' => $this->cm->id, 'fileid' => $file->get_id()), '/mod/assignment/locallib.php'); Now becomes: $button->set_callback_options('assignment_portfolio_caller', array('id' => $this->cm->id, 'fileid' => $file->get_id()), 'mod_assignment'); === 2.3 === required changes: * The following methods must now be declared static for php5 compatibility: - admin_config_form - admin_config_validation
