So over the past few weeks I have been working on the App Store / CCSystems php script.
I have added new things including comments systems, updateing/editing programs, but now I am stuck on what next to add.
So here is what I ask, would you be able to give me some awesome ideas that should be added to the App Store?
These can be things like rating systems or extra functions to help you use the store.
Another thing is before I do who is up for using the CCSystems User Database? I have had this working and already have over 100 users registered. Currently you can register and login, the idea was to have a centralised database so everyone can use the same database. This is all up to you but I have released a few code snippets for you to use which are below so you can also use the system!
If you have any ideas on what next to add then do tell me!!
Code uses sha256 to hash the password, please don't stop this otherwise people won't be able to login/out.
How to use:
Copy the large code below and put it at the top of your program, then use the following functions to use:
users.login(<username>, <password) -- login
users.register(username, email, password)
-- Username and password (and email if registering) will need to be got using a read function etc.
users = {}
users.__index = users
function users.login(username, password)
local req = http.post("https://ccsystems.dannysmc.com/ccsystems.php", "ccsys="..textutils.urlEncode(tostring("user")).."&cccmd="..textutils.urlEncode(tostring("login")).."&username="..textutils.urlEncode(tostring(username)).."&password="..textutils.urlEncode(tostring(users.sha256(password))))
local status = req.readAll()
if status == "true" then
return true
else
return false
end
endfunction users.register(username, email, password)
local req = http.post("https://ccsystems.dannysmc.com/ccsystems.php", "ccsys="..textutils.urlEncode(tostring("user")).."&cccmd="..textutils.urlEncode(tostring("register")).."&username="..textutils.urlEncode(tostring(username)).."&password="..textutils.urlEncode(tostring(users.sha256(password))).."&email="..textutils.urlEncode(tostring(email)))

return true
