function Course::load_course_from_data_string

6.x Course.php Course::load_course_from_data_string($str)
7.x Course.php Course::load_course_from_data_string($str)

This will take a data string, as created by the function to_data_string(), and make $this object match the original object. It is a poor man's unserialize. See to_data_string()'s description for a fuller picture of what is going on.

To use:

  • $newCourse = new Course();
  • $newCourse->load_course_from_data_string($data);

Parameters

string $str:

1 call to Course::load_course_from_data_string()
Course::load_course_from_data_string_for_requirement_clone in classes/Course.php
This function uses load_course_from_data_string, but it removes any elements which might interfere with the course object then being used as a requirement. This is used specifically by the FlightPath object, when creating a clone of a repeatable course.
