unable to display values from array in a view

I already suggested in this thread:
https://forum.codeigniter.com/thread-69443.html
to use a JOIN statement to fetch the data in one query.

Besides that, you can't compare dates that are converted to an international date format string. "26-01-2017" is greater than "04-11-2017", but that's not the result that you want, do you?
