Re: Backup course by section via CLI

by Carlo Ditan.  

First, I added the sectionid as a parameter for the command. 

list($options, $unrecognized) = cli_get_params(array(
    'courseid' => false,
    'sectionid' => false,     // this is the added parameter
    'courseshortname' => '',
    'destination' => '',
    'help' => false,
    ), array('h' => 'help'));

Second, I added the sectionid as an additional condition to be queried in fetching a record from the course_sections table. Take note that both courseid and sectionid parameters should be present.  The command will throw an invalidrecord exception if the pair doesn't exist in the course_sections table.

if($options['sectionid'] && $options['courseid']) {
    $section = $DB->get_record('course_sections', array('id' => $options['sectionid'], 'course' => $options['courseid']), '*', MUST_EXIST);
} else if($options['courseid']) {
    // get course record by ID
} else {
    // get course record by shortname
}

Third, I added a condition wherein the backup controller will use the section type and ID, instead of course.

if($section) {
    $bc = new backup_controller(
        backup::TYPE_1SECTION, $section->id,
        backup::FORMAT_MOODLE, backup::INTERACTIVE_YES,
        backup::MODE_GENERAL, $admin->id);
}
else {
    $bc = new backup_controller(
        backup::TYPE_1COURSE, $course->id,
        backup::FORMAT_MOODLE, backup::INTERACTIVE_YES,
        backup::MODE_GENERAL, $admin->id);
}

That's basically what I did. The implementation can be improved though.
