Another addon to cast your eye over - lock pages

[frankl]

We have to make sure that order edit, product edit, and customer edit pages are locked so changes can't be made by other admins at the same time. Please check this addon I created before I make it public.

Only tested with 1.0.9.5 and 1.0.9.6 so far

Lock Admin Pages for Phoenix Cart
____________________________________

Locks page to current admin to prevent changes by other admins.

Shows a button to unlock page if necessary.

Works on order edit, product edit, and customer edit.

As the addon relies on the navigator.sendBeacon and unload javascript functions, this may not work on mobile devices or when page is refreshed on desktop.

To clean up any locked pages in the database, they are unlocked automatically after 30 minutes of inactivity.

Installation

Backup your database.

Upload the files, nothing will be overwritten. lock_pages database table will be created on first use.

Nothing to install. After uploading, visit an order edit, product edit, or customer edit page using one admin,
then open same page on another computer logged in as a different admin. You should see the page is locked.
