Lua data/global.lua:55: attempt to get length of local 'str' (a boolean value)

Shadow_ · Jul 19, 2018

Hello guys as always when i try to use 0.4 scripts in my 1.2 tfs it always works except this i want to add offline msg script so i searched and i found a script but it didn't work for me.
i added those to my global.lua
1:

LUA:

messageSep = "<msgSep>" --used on database
senderSep = "<sendSep>" --used on database
function getPlayerMessages(name)
    local query = db.storeQuery("select messages from players where name = " .. db.escapeString(name) .. ";")
    local messages = {}
    local x
    if query ~= -1 then
        x = result.getDataInt("messages")
        x = string.explode(x, messageSep)
        for i = 1, table.maxn(x) do
            table.insert(messages, x[i])
        end
    end
    return messages
end
function doPlayerAddMessage(name, message, sender)
    local query = db.storeQuery("select messages from players where name = " .. db.escapeString(name) .. ";")
    if query ~= -1 then
        local m = result.getDataInt("messages")
        m = m .. (m ~= "" and messageSep or "") .. message .. senderSep .. getCreatureName(sender) .. senderSep .. os.date()
        local newquery = db.storeQuery("update players set messages = " .. db.escapeString(m) .. " where name = " .. db.escapeString(name) .. ";")
        if not newquery then
            return false
        end
    else
        return false
    end
    return true
end
function doPlayerRemoveMessages(name)
    local query = db.storeQuery("update players set messages = '' where name = " .. db.escapeString(name) .. ";")
    if not query then
        return false
    end
    return true
end
function getPlayerMessagesLenght(name)
    local query = db.storeQuery("select messages from players where name = " .. db.escapeString(name) .. ";")
    if query ~= -1 then
        return string.len(result.getDataInt("messages"))
    end
    return -1
end

and i already had this for string.explode :

LUA:

function string.trim(str)
    -- Function by Colandus
    return (str:gsub("^%s*(.-)%s*$", "%1"))
end
function string.explode(str, sep, limit)
    -- Function by Colandus
    if limit and type(limit) ~= 'number' then
        error("string.explode: limit must be a number", 2)
    end
    if #sep == 0 or #str == 0 then return end
   local pos, i, t = 1, 1, {}
    for s, e in function() return str:find(sep, pos) end do
        table.insert(t, str:sub(pos, s-1):trim())
        pos = e + 1
        i = i + 1
        if limit and i == limit then break end
    end
    table.insert(t, str:sub(pos):trim())
    return t
end

and the talkaction script :

LUA:

local maxMessageLenght = 1500
local deleteMessageAsRead = false
function onSay(cid, words, param, channel)
    local msg = getPlayerMessages(getCreatureName(cid))
    if words == "!msg" then
        param = string.explode(param, ";")
        if table.maxn(param) < 2 then
            return doPlayerSendCancel(cid, "No player specified.")
        end
        if param[2]:lower() == getCreatureName(cid):lower() then
            return doPlayerSendCancel(cid, "You cannot send messages to yourself.")
        end
        if string.len(param[1]) > maxMessageLenght then
            return doPlayerSendCancel(cid, "Message is too long, only " .. maxMessageLenght .. " characters are admitted.")
        end
        if playerExists(param[2]) and getPlayerMessagesLenght(param[2]) >= 10000 then
            return doPlayerSendCancel(cid, "You cannot send more messages to " .. param[2] .. " until he/she clean his/her inbox.")
        end
        if doPlayerAddMessage(param[2], param[1], cid) then
            doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, "Message successfully sended to " .. param[2] .. ".")
            if getPlayerByNameWildcard(param[2]) then
                doPlayerSendTextMessage(getPlayerByNameWildcard(param[2]), MESSAGE_INFO_DESCR, "You have received a new private message.")
            end
        else
            doPlayerSendCancel(cid, "Player with that name does not exists.")
        end
    elseif words == "!read" then
        doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "Reading " .. table.maxn(msg) .. " message(s)" .. (not deleteMessageAsRead and getPlayerMessagesLenght(getCreatureName(cid)) >= 10000 and ", your inbox is full, you should delete messages or you won't receive more messages" or "") .. ".")
        if table.maxn(msg) > 0 then
            for i = 1, table.maxn(msg) do
                local t = string.explode(msg[i], senderSep)
                doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "Message from " .. t[2] .. " at " .. (t[3] or "No Date") .. " > " .. t[1])
            end
        end
        if deleteMessageAsRead and table.maxn(msg) > 0 then
            if doPlayerRemoveMessages(getCreatureName(cid)) then
                doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "The following message(s) have been deleted.")
            end
        end
    elseif words == "!delete" then
        local limit = (tonumber(param) and tonumber(param) > 0 and tonumber(param) <= table.maxn(msg) and tonumber(param) or table.maxn(msg))
        if doPlayerRemoveMessages(getCreatureName(cid), limit) then
            doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "You have deleted " .. limit .. " message(s).")
        end
    end
    return true
end

and lastly this in login.lua :

LUA:

    local msg = getPlayerMessages(getCreatureName(cid))
    if table.maxn(msg) > 0 then
        return doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "You have " .. table.maxn(msg) .. " new message(s).")
    end

can anybody help me ? iam using tfs 1.2 ( the script is 0.4 i know but 0.4 scripts usually works for 1.2 )

change

LUA:

return string.len(result.getDataInt("messages"))

to

LUA:

return string.len(result.getDataInt(query, "messages"))

you have more than 1 of those errors in your code, result.getDataInt(queryid, "column_name")
you're omitting the query id parameter, you can't get a data int from a column if you don't provide the query result in that function

before editting it it was like this

LUA:

        return string.len(query:getDataString("messages"))

and i changed it to

LUA:

return string.len(result.getDataInt("messages"))

+ i tried yours i got this

Code:

data/global.lua:55: attempt to get length of local 'str' (a boolean value)

on login and when i delete the login lines and try the command same error with the command files

which script is the error actually coming from?
i'm not a wizard, i don't feel like sitting here guessing if you don't give the full error

LUA:

function string.explode(str, sep, limit)
    -- Function by Colandus
    if limit and type(limit) ~= 'number' then
        error("string.explode: limit must be a number", 2)
    end
    if #sep == 0 or #str == 0 then return end
   local pos, i, t = 1, 1, {}
    for s, e in function() return str:find(sep, pos) end do
        table.insert(t, str:sub(pos, s-1):trim())
        pos = e + 1
        i = i + 1
        if limit and i == limit then break end
    end
    table.insert(t, str:sub(pos):trim())
    return t
end

I just did a simple ctrl+f on code you provided and the only place that looks for the length of str is this:

LUA:

if #sep == 0 or #str == 0 then return end

The hash # in front of str returns the size of str if its a string, char or table.
So to trouble shoot the issue with the error you have to account for the data str might be holding.

This may not solve the entire problem you but it may resolve the current error.

LUA:

function string.explode(str, sep, limit)
    -- Function by Colandus
    if limit and type(limit) ~= 'number' then
        error("string.explode: limit must be a number", 2)
    end
    -- lets make sure str is a string
    if type(str) ~= "string" then
        return
    end
    if #sep == 0 or #str == 0 then
        return
    end
    local pos, i, t = 1, 1, {}
    for s, e in function() return str:find(sep, pos) end do
        table.insert(t, str:sub(pos, s-1):trim())
        pos = e + 1
        i = i + 1
        if limit and i == limit then break end
    end
    table.insert(t, str:sub(pos):trim())
    return t
end

We know that str is a string not just because it's labeled "str" but because of the methods that are applied to it later on in the script such as find, sub and so forth.

I guess it would be easier to find the issues if you posted the entire global file.

[Lua] global.lua - Pastebin.com

Digital · Jul 20, 2018

This is lines 485 to 497

LUA:

function getPlayerMessages(name)
    local query = db.storeQuery("select messages from players where name = " .. db.escapeString(name) .. ";")
    local messages = {}
    local x
    if query ~= -1 then
        x = (result.getDataString(query, 'messages'))
        x = string.explode(x, messageSep)
        for i = 1, table.maxn(x) do
            table.insert(messages, x[i])
        end
    end
    return messages
end

and this is line 492

LUA:

for i = 1, table.maxn(x) do

So this error says that max is expecting a table but instead its getting nil. This function in general is expecting a table to be passed to it from x as if x is guaranteed to contain a value.

Code:

data/global.lua:492: bad argument #1 to 'maxn' (table expected, got nil)

Even an empty table contains a value print(table.maxn({})) would print 0.
So lets wrap this for loop with an if statement

LUA:

function getPlayerMessages(name)
    local query = db.storeQuery("select messages from players where name = " .. db.escapeString(name) .. ";")
    local messages = {}
    local x = nil
    if query ~= -1 then
        x = (result.getDataString(query, 'messages'))
        x = string.explode(x, messageSep)
        -- does x contain a value and if it does is that value a table?
        if x and type(x) == "table" then
            -- if x is a table but has nothing in it then the for loop won't even execute
            for i = 1, table.maxn(x) do
                table.insert(messages, x[i])
            end
        end
    end
    return messages
end

I'll assume the script you posted above is the one which is throwing these errors? I got a little clever and wrote you a universal table function.

LUA:

-- table.length(t, c[, l])
function table.length(t, c, l)
    local v = false
    if t and type(t) == "table" then

            local n = table.maxn(t)
            -- return just the size
            if c == "size" then
                return n
            end
            -- return the original table
            if c == "table" then

I'll assume the script you posted above is the one which is throwing these errors? I got a little clever and wrote you a universal table function.

LUA:

-- table.length(t, c[, l])
function table.length(t, c, l)
    local v = false
    if t and type(t) == "table" then
        if c then
            local n = table.maxn(t)
            -- return just the size

Solved .
Add this in global.lua

    if query ~= -1 then
        x = (result.getDataString(query, 'messages'))
        x = string.explode(x, messageSep)
        -- does x contain a value and if it does is that value a table?
        if x and type(x) == "table" then
            -- if x is a table but has nothing in it then the for loop won't even execute
            for i = 1, table.maxn(x) do
                table.insert(messages, x[i])
            end
        end
    end
    return messages
end
function doPlayerAddMessage(name, message, sender)
    local query = db.storeQuery("SELECT `messages` FROM `players` WHERE `name` = " .. db.escapeString(name))

        m = m .. (m ~= "" and messageSep or "") .. message .. senderSep .. getCreatureName(sender) .. senderSep .. os.date()
        local newquery = db.query("UPDATE `players` SET `messages` = " .. db.escapeString(m) .. " WHERE `name` = " .. db.escapeString(name))
