Send data from client to server

[thund3rbird23]

I have an input label in client side called "fakeInputs.Message" and I want to process this label's value in server side and insert this value to the database it's possible?

Here is how works the input label:

function processFakeInput(key, forcedInput)
	local theInput, inputType, maxChar = getActiveFakeInput(type(forcedInput) == "string" and forcedInput or false)

	if theInput then
		if not fakeInputs[theInput] then
			fakeInputs[theInput] = ""
		end

		if key == "enter" then

		elseif key == "backspace" then
			fakeInputs[theInput] = utf8.sub(fakeInputs[theInput], 1, -2)
		else
			if maxChar > utf8.len(fakeInputs[theInput]) then
				if inputType == "num-only" then
					if tonumber(key) then
						fakeInputs[theInput] = fakeInputs[theInput] .. key
					end
				else
					fakeInputs[theInput] = fakeInputs[theInput] .. key
				end
			end
		end
	end
end

So in server side I need something like this ( ofc, that doesn't work because I don't know how to get the value from client side):

 

dbExec(connection, "INSERT INTO messages VALUES (?)", fakeInputs.Message)

Thanks, I did with your suggestion:

 

-- Client-side

local guiText = guiGetText(pin)
triggerServerEvent("check", resourceRoot, guiText) -- pass data

-- Server-side

function checkEvent(text)
	outputChatBox(text)
end
addEvent("check", true)
addEventHandler("check", resourceRoot, checkEvent)

But what about if I have something in server side and I want to display it in client side?

Example (I want to display the "res" in client side):

function LoadMessages()
local query = dbQuery(connection, "SELECT * FROM messages WHERE characterID = 1")
local result = dbPoll(query,-1)	
for x, ad in ipairs( result ) do
local res = result[x]['message']
end
end
addEvent("LoadMsg", true)
addEventHandler("LoadMsg", resourceRoot, LoadMessages)

Use

triggerClientEvent

Do not use dbPoll with -1 query time, its will couse server side freeze if one of the query comeback with timeout. You can use the dbQuery's callback function with zero timeout instead of, like this:

 

function LoadMessages()
local query = dbQuery(function(qh)
	result = dbPoll(qh,0)	      
end,connection, "SELECT * FROM messages WHERE characterID = 1")
for x, ad in ipairs( result ) do
local res = result[x]['message']
end
end
addEvent("LoadMsg", true)
addEventHandler("LoadMsg", resourceRoot, LoadMessages)

Thanks!

But I still don't know how to display that in client side.

By sending it back

 

Serverside

local something = "something"
triggerClientEvent(player, "sending-something-back" resourceRoot, something)

player = sending it specific to that player.

 

Clientside

addEvent("sending-something-back", true)
addEventHandler("sending-something-back", resourceRoot,
function (something) 
  outputChatBox(something)
end, false)

 

 

 

If you want to work with callbacks instead, you need an enchantment of the feature.
