On one page of my app, the user will select certain settings (like what a customer ordered for example) and then upload to the database. Then, another user needs to download those settings (perhaps to make the order). HOW DO I DO THIS??
One user would save data into the database and the other user would read data from a databgase.
You should be a little bit more specific. If you are new to Appery.io, please read http://docs.appery.io/getting-started. Then try our tutorials on how to read/save data into the database.
Like basically, i'm trying to make an app for a restaurant. one page of the app would be a "ticket" that would have the different menu items on it. they would select the items that the customer wants, then send it to the kitchen.
so I'm trying to figure out how i should save the selected files to the database in a way that would be easy to read for the other users
I apologize if it doesn't quite make sense. I have a hard time conveying what I see in my head over text
