I had my final exams this week, so I only had chance to study core classes and functions I will use, like WPDB and WP_Filesystem. I tested WPDB functions to see which returns what and how, as I will be using it for my first task: writing the database backing up tool. Also, to avoid further confusions, I should note that when I use the word “tool”, I am referring the code, not the whole user interface. So a working user interface (and plugin, of course) will not be available until all the necessary tools are written. And as I stated on my schedule, UI will reach its final state by July 4th. Just wanted to make it clear.
Anyway, as my exams are over, now I can completely focus on the project. See you next week!
