Wordpress/Memberpress - Custom page - Bug Fixes Required

Hi, I have a wordpress website with a membership area controlled by Memberpress. I've developed some code for a bespoke page within a Membership area where users complete checkboxes + input boxes each week in a 'Planner', which saves to a DB. I have a few bugs i need fixing: > Bug 1 = Input text boxes - Not saving correctly .on('focusout', function () (Sometimes the input box saves, other times it doesn't?) -> Possible fix: Check focusout code for bugs to fix. -> Possible fix: Develop SAVE button to capture all and save to DB Bug 2 = Require Week to start at 00:01 Monday ( The Planner refreshes each week, and presents the user with an empty planner. Currently my issue is that this starts the new week at Sunday 12pm -- I Need this set to Sunday 23:59 ) Bug 3 = On a separate page 'Archive', the user can access previous planners based on a weekly links. -> I require new code to show users previous weeks of inputted data from the planner. IE: ..../planner/?date=2021-09-12 ( The user can see their planner that they filled out the previous week, as it was, on the final moments (sunday 23:59) -- The user needs to be able to see all previous weeks they have currently been a member for. ) For this i need code written to: - Check when user signed up / And show previous weeks they have inputted date for. IE = If user has been signed up for 2 weeks, they get shown 2 links: Planner 26/09/2021 / Planner 19/09/2021 --- Majority of the code written, just require bug fixes + this extra 'Archive system' code. Written in SQL, PHP, jQuery.
