Hi again,
So, I’ve finally put together my little script that allows me to schedule weekly days off.
You can find it here: https://github.com/chipmanaged/MCM-Dashboard
It’s the file called dayoffscheduler.php
In order to work, it needs, as a minimum, the settings-userinfo.php file with your info in it (placed in the same directory), and a copy of the PHP API library.
I’m going to say more about this elsewhere so, for now, I’ll just point out that you need to type in your goal slug (in lowercase), select the day of the week to which to apply the different rate, enter the rate, and hit “Enter!” (Repeat as necessary; e.g. for Saturday and then Sunday.)
It’s neither perfect nor done, but it’s a start! I hope it proves useful to others.
