I was approached by a long standing customer who uses the inbuilt “Order Status” system a lot (eg change from processing to delivered and so on). A nuisance of the system is that he had to copy and paste the same message multiple times per day when updating.
I know there are at least a couple of addons that can do the job, but they are all old, broken, tired, crap. So I set up to code up an integrated system that allows the shopowner to attach a message to each order status;
– took about 10 lines of code in orders_status.php file
Now when the status dropdown is changed, the system finds the relevant message and inserts into the comments box.
– 1 new block of code in orders.php
Non-invasive (although obviously as it is Admin side, there are core code changes), easy to use and solid.
