PTA SUS – Changing event date without dropping signups?

Easiest way would be to directly modify the dates in the custom tables for the plugin, using PHPMyAdmin, or similar database tool. 3 tables, pts_sus_sheets, pta_sus_tasks, pta_sus_signups, all prefixed by your WordPress database prefix (usually wp_).

For the signup table, where you have that many signups, probably easiest to do a search/replace SQL operation for that date, possibly including the task id if you have other tasks from other sheets on the same date that you don’t want changed.

Otherwise, there is nothing built-in to the plugin to allow you to modify dates once people have signed up. In fact, just the opposite, it won’t let you change the date for a task if there are already people signed up for that date, as that would break the operation of the plugin.

I’m happy to accept any contributions from other developers, and can incorporate it into the plugin if it’s something that might be useful to others.

Yes, the database structure was already setup by the plugin I forked my version from. It was also one of the first plugins I did for our PTA when still learning a few years back, so I was still learning database structure and MySQL operations as I expanded the features of the plugin.

If I was starting on it again from scratch today, I would definitely do things in a different/better way.

Last year I actually started totally rewriting from scratch the entire PTA Manager system I created for the grade school, in a much more true OOP way. But, then I got hired for some much bigger custom WooCommerce jobs, and my own Wholesale Ordering extension started taking off, and then my son graduated from that school and the new PTA team decided to go with one of the hosted PTA solutions, so I abandoned that project (at least for now), and am only keeping up with fixes/updates for the two independent plugins from the original system that I released at WordPress.org. Happy to take on other developers who want to contribute/add more features to the existing PTA plugins, but they are fairly low priority for me now.
