Opening the database and manually adding items can be a hassle, or confusing if you are new. All that tabbing out nonsense.
I put this together to easily add new items to your esx items database in game, then just restart the server when you are finished.
I made it with okoknotify, change that if you want. Also change the sql table/columns if you need.
If you dont get the success notification check the server console for duplicate entries.
Not entirely true - There are a lot people that use the database version, but this can also be edited for anything. MF Inventory is still popular and uses the DB. Anything you need to add to the Db just changing the columns around.
I was looking into seeing if the ox inventory items lua can be adjusted, but it would have to be a JSON file which it is not.
