I want to add 'end date' for the courses. I have done below things so far.
- Showing a end date in add/edit course settings page using custom scripts.
- Creating a new table for storing the end_date of the course. This table has 3 columns (id, course_id, end_date).
- Storing the end date in table using custom scripts.
- Retrieving the end date in course settings page.
Now I want to add the course end date in a course object meaning that when the course(s) are extracted from database. Lets say method "get_courses_records" in "coursecat" class defined in lib/coursecatlib.php file is used to get the courses from database, then I want to change that code in order to get the course end date for the course which is stored in another table. But I can not make the changes in existing core code.
So how can I achieve this?
Thanks in advance!
