triggerClientEvent

[Bebras]

Hello, so my topic name is not very informative as i don't really know where the problem is...

Anyway, this is my server-side code:

function checkPlayer(playerNick) 
    local result = mysql_query(handler,"SELECT * FROM users WHERE Name = '"..playerNick.."'") 
    if( not result) then outputDebugString("MySQL Fail ("..mysql_errno(handler)..") Error:"..mysql_error(handler)) 
    end 
    if(mysql_num_rows(result) == 0) then 
        triggerClientEvent("onRegister",getRootElement()) 
        outputDebugString("Should be triggered") 
    else 
        row = mysql_fetch_row(result) 
         
    end 
    mysql_free_result(result) 
end 
addEventHandler("onPlayerConnect",getRootElement(),checkPlayer) 

and this is my client-side code:

function registerHandler() 
    outputDebugString("Function for registering is called") 
end 
addEvent("onRegister",true) 
addEventHandler("onRegister",getRootElement(),registerHandler) 

And the string "function for registering is called" isn't printed out.. I did it exactly like in the wiki, and yet i failed somehow...

where is the problem?

What if you use getLocalPlayer () and not getRootElement ()

[Bebras]

If you meant here:

addEventHandler("onRegister",getLocalPlayer(),registerHandler) 

, then it didn't help

[kevenvz]

No look:

triggerClientEvent("onRegister",getLocalPlayer()) 

You are triggering a client event and you need a player to handle that.

[Bebras]

Tried it, got this error: attempt to call global 'getLocalPlayer'

Off-topic: what is "nil" is it like null?

[kevenvz]

Nil is it doesn't contain a value.

How about you use: getPlayerFromName(playerNick)

[Bebras]

No errors, but still it is not printed

It's because this:

   if(mysql_num_rows(result) == 0) then 

It checks if the rows are 0 then trigger it to the client.

and kevenz, getLocalPlayer()[localPlayer] on the server? LAL, that doesn't make any sense

[kevenvz]

I know it is source, totally forgot that

[Bebras]

It's because this:

   if(mysql_num_rows(result) == 0) then 

It checks if the rows are 0 then trigger it to the client.

and kevenz, getLocalPlayer()[localPlayer] on the server? LAL, that doesn't make any sense

I'm sorry, what is wrong with it? Because you just described what i want it to do

Wel, you should debug it:

function checkPlayer(playerNick) 
    local result = mysql_query(handler,"SELECT * FROM users WHERE Name = '"..playerNick.."'") 
outputChatBox ( "Result: "..result ) 
    if( not result) then outputDebugString("MySQL Fail ("..mysql_errno(handler)..") Error:"..mysql_error(handler)) 
    end 
outputChatBox ("mysql_num_rows: " ..mysql_num_rows(result)) 
  
    if(mysql_num_rows(result) == 0) then 
        triggerClientEvent("onRegister",getRootElement()) 
        outputDebugString("Should be triggered") 
    else 
        row = mysql_fetch_row(result) 
       outputChatBox ("row: " ..mysql_num_rows(result)) 
    end 
    mysql_free_result(result) 
end 
addEventHandler("onPlayerConnect",getRootElement(),checkPlayer)

No look:

triggerClientEvent("onRegister",getLocalPlayer()) 

You are triggering a client event and you need a player to handle that.

triggerClientEvent is server-side only and getLocalPlayer is client-side only.

Wel, you should debug it:

function checkPlayer(playerNick) 
    local result = mysql_query(handler,"SELECT * FROM users WHERE Name = '"..playerNick.."'") 
outputChatBox ( "Result: "..result ) 
    if( not result) then outputDebugString("MySQL Fail ("..mysql_errno(handler)..") Error:"..mysql_error(handler)) 
    end 
outputChatBox ("mysql_num_rows: " ..mysql_num_rows(result)) 
  
    if(mysql_num_rows(result) == 0) then 
        triggerClientEvent("onRegister",getRootElement()) 
        outputDebugString("Should be triggered") 
    else 
        row = mysql_fetch_row(result) 
       outputChatBox ("row: " ..mysql_num_rows(result)) 
    end 
    mysql_free_result(result) 
end 
addEventHandler("onPlayerConnect",getRootElement(),checkPlayer) 

It does output: "should be triggered"

triggerClientEvent(PlayerToSendInfoTo, "onRegister", root) 

[denny199]

triggerClientEvent(PlayerToSendInfoTo, "onRegister", root) 

Thats optional, is your meta.xml allright, have you tried changing the trigger name from onRegister to "login:onRegister"??
