Prestashop module update

To do : Hi, The job is about a Prestashop existing module called AftershipCheck, it is available on [login to view URL] The module track delivery of orders using Aftership API. It has been tested until Prestashop version 1.7.2.2 The main issue is that it uses overrides which are not working anymore in last Prestashop versions. The work required is to make it work on all the latest versions since 1.7.2.2 without breaking 1.6 versions. The code has to be clear (commented), maintainable and agree Prestashop standards because the module is published on addons, and the features have to be tested in enough Prestashop versions to warranty a full adaptability. Here are the main features that must work in any version (1.6/1.7): - Add to backoffice orders page two bulk actions: - "Delivery checking" (DC): Select one or many orders and call Aftership API to get last delivery status for orders that satisfied some filters (right status : more info in code) - "Send order tracking information" (SOTI): Select one or many orders and call Aftership API to send information about these orders that satisfied some filters (right status : more info in code) - Cron job: These two actions (DC and SOTI) can be done automatically by cron job in the last orders according to setting (more information in module setting page and in code) - Automatically update order status when the user fill the tracking number according to the module settings - Automatically trigger action SOTI when the user fill the tracking number according to the module settings Optional work (if time): Improve Module setting page interface If the job is done well, other modules updates would come next.
