[SOLVED] Connected Login Panel to IPS Communite Suite!

FlyingSpoon · January 2, 2016

I am trying to connect my Login Panel to my IPS Forum Board.

I am really confused at this point at what to do, I read through this topic and saw the code.

I have connected my server side script to my Forum Database but the problem now is that I think the password hash is incorrect like you know, blowfish. Any ideas how I can connect my login panel to the forum?

Here's my current server sided code -

local hostname = "0.0.0.0"  
local database = "*****" 
local user = "*****" 
local pass = "*****" 
  
function PlayerLogin(username, password) 
    local db = dbConnect("mysql", "dbname="..database..";host="..hostname, user, pass) 
    if db then 
        local query = dbQuery(db, "SELECT members_pass_hash, members_pass_salt FROM mvp_core_members WHERE name = '" .. username .. "' ") 
        local query = dbPoll(query, -1) 
        if #query ~= 0 then 
            local data = query[1] 
            local hash = lowermd5(lowermd5(data.members_pass_salt) .. lowermd5(password)) 
            if hash == data.members_pass_hash then 
                outputDebugString("Correct") 
            else 
                outputDebugString("Incorrect") 
            end 
        else 
            outputDebugString("User not found") 
        end 
    end 
    destroyElement(db) 
end 
addEvent("onRequestLogin",true) 
addEventHandler("onRequestLogin",getRootElement(),PlayerLogin)

There are two ways - edit system/member/member.php in IPS (it might get overridden when updating IPS later though) and edit authentication (change to MD5 hash) - you'll also have to reset your password.

The other way is to callRemote PHP that would do all database and password verification and report back to the server

FlyingSpoon · January 2, 2016

Okay, if I was to use callRemote how would I go about doing this?

Where do I start?

I put the PHP SDK (mta_sdk.php) on my forums then?

Addlibs · January 2, 2016

// PHP 
  
include 'mta_sdk.php';  // Correct path if you use a different one 
$servername = "127.0.0.1";  // Change these details 
$username = "dbuser";  // Change these details 
$password = "dbuserpassword";  // Change these details 
$dbname = "dbschema";  // Change these details 
$table = "core_members"; 
$accountColumn = "members_seo_name";  // change to "email" if you prefer logging in through email 
$conn = mysqli_connect($servername, $username, $password, $dbname); 
if (!$conn) { 
    mta::doReturn(false, "Connection failed: " . mysqli_connect_error()); // Account not found 
    #die("Connection failed: " . mysqli_connect_error()); 
} 
$input = mta::getInput(); 
if (isset($input[0]) && isset($input[1]) && isset($input[2]) && $input[0] == "verifyPasswords" ) { 
    $sql = "SELECT `members_pass_salt`, `members_pass_hash` FROM `".$table."` WHERE `".$accountColumn."`='".strtolower($input[1])."' LIMIT 1"; 
    $result = mysqli_query($conn, $sql); 
    if (mysqli_num_rows($result) > 0) { 
        $row = mysqli_fetch_assoc($result); 
        if (crypt($input[2], '$2a$13$' . $row['members_pass_salt']) == $row['members_pass_hash']) { 
            mta::doReturn(true, 0);  // Password correct 
        } else { 
            mta::doReturn(false, 1);  // Passwords don't match 
        } 
    } else { 
        mta::doReturn(false, 2);  // Account not found 
    } 
}

local username, password = "johnsmith", "password123" 
callRemote("URL to .php file", function(response, extra)

    if extra == 1 then 
      -- password incorrect 
    elseif extra == 2 then 
      -- account not found 
    end 
  end 
end, "verifyPasswords", username, password)

function PlayerLogin(username, password) 
callRemote("[Link]", function(response, extra) 
  if response == true then 
   outputDebugString("Right Pass.") 
  else 
    if extra == 1 then 
    outputDebugString("Wrong Pass.") 
    elseif extra == 2 then 
     outputDebugString("Not found.") 
    end

Doesn't work, or output anything

Addlibs · January 2, 2016

It works for me (tested through runcode and outputServerLog). Have you prefixed your PHP with

<?php

If not, you need to do that.

FlyingSpoon · January 2, 2016

Yes, I just added them, but same thing. Nothing still outputted.

function PlayerLogin(username, password) 
callRemote("[Link]", function(response, extra) 
  if response == true then 
   outputDebugString("Right Pass.") 
  else 
    if extra == 1 then 
    outputDebugString("Wrong Pass.") 
    elseif extra == 2 then 
     outputDebugString("Not found.") 
    end 
  end 
end, "verifyPasswords", username, password) 
end 
addEvent("onRequestLogin",true) 
addEventHandler("onRequestLogin",getRootElement(),PlayerLogin)

Addlibs · January 2, 2016

Try using the following as callback

[…] 
function(...) 
  outputDebugString(toJSON({...})) 
end 
[…]

Also, try checking the error log on your HTTP server. There might be an error in the PHP file itself, especially if the above code outputs something like [ [ "Error", "500" ] ] in the debug

FlyingSpoon · January 2, 2016

function PlayerLogin(username, password) 
callRemote("[link]", function(response, extra) 
  if response == true then 
   outputDebugString(toJSON({"Right Password!"})) 
  else 
    if extra == 1 then 
   outputDebugString(toJSON({"Wrong Password!"})) 
    elseif extra == 2 then 
   outputDebugString(toJSON({"User doesnt exist!"})) 
    end 
  end 
end, "verifyPasswords", username, password) 
end 
addEvent("onRequestLogin",true) 
addEventHandler("onRequestLogin",getRootElement(),PlayerLogin)

Did I do it wrong? Because nothing is outputted still.

The above is my PHP File and the other is my code.

Addlibs · January 2, 2016

I meant like

callRemote("[link]", function(...) 
  outputDebugString(toJSON({...})) 
end, "verifyPasswords", username, password)

FlyingSpoon · January 2, 2016

callRemote("[link]",  function(response, extra) 
  outputDebugString(toJSON({"Success!"})) 
end, "verifyPasswords", username, password)

Like this?

Addlibs · January 2, 2016

No no, don't replace the ellipsis, it's part of Lua syntax

FlyingSpoon · January 2, 2016

Ohh...sorry my bad.

FlyingSpoon · January 2, 2016

It outputs Error 500

Addlibs · January 2, 2016

That is indeed an internal error (within the PHP). Going to look at the PHP code.

Update: At line 6, in the disguised $username, you're missing an ending double-quote-mark — is that just a mistake when censoring details or is that in the actual PHP as-well?

function PlayerLogin(username, password) 
callRemote("[LINK]", function(...)

addEvent("onRequestLogin",true)

This is my LUA Sided Script just in-case!

FlyingSpoon · January 2, 2016

There's a double quoted mark, it's just on MTA Forums, I accidentally removed it. But on the original script, there is a double-ended quoted mark.

Is mta_sdk.php in the same directory as my php file?

FlyingSpoon · January 2, 2016

Yes, it's in the same directory.

FlyingSpoon · January 2, 2016

Got it to work! I accidentally used the wrong mta_sdk.php (MACOSX) Which was the wrong one.

FlyingSpoon · January 2, 2016

Thank you so much, this helped a lot. One last question how can I fetch data like, say if I want to save money, because I see this is all done via callRemote, say if I was to save money in the database, how would I get that type of data?

Addlibs · January 2, 2016

Change the SQL query to select all columns (SELECT *) and then in the logon successful mta::doReturn add more arguments in the format $row['columnName'] add another argument, $row. They will be sent over as additional parameters to the callback function in Lua.

Also, nota bene that column 'name' (which you're using) stores a case-sensitive username, and my PHP transforms the input into lowercase. Either use 'members_seo_name' or remove

strtolower() // don't remove what's between the brackets

from the query in the WHEN part of the statement.
