Answer

You can initiate a Message model class to represent the records in your messages table and then listen for the updating or updated event on that model, which fires everytime a record has been updated or is currently updating. There you can check if the updated property is the needed one (in your case – status) and execute the code you desire. I suggest you check the documentation on how to work with eloquent models (if you haven’t yet) and look up the provided events. That should do the work. Here is the documentation
