Background
So I recently started converting a dudb based save system to SQLite. That proved to be a bit difficult but I managed to pull through except for one issue... It would never create the database. I then decided that I would convert it to MySQL since there seems to be more support for it. I followed [HiC]TheKiller's tutorial and I have run into a bit of a problem.
The Problem
When I register, everything goes well - account is inserted into the database, everything is updated on disconnect, etc. but when the time comes that I reconnect/log back in, the dialog appears but as soon as I enter the password and press 'Login' the server window closes and then client-side, the server disconnects and is attempting to reconnect.
Code
So here is the code that I think could shed a bit of light on the situation at hand.
OnPlayerConnect - I am led to believe that the problem isn't under this particular callback but here it is for reference.
ShowPlayerDialog - I don't believe that the problem is here either but still, pasted for reference.
MySQL_Login - the stock created for the purpose of logging in the player/getting variables from the database.
Debug.txt - Activated 'Debug' mode in the script to get a better look at things.
server_log.txt - Here are the lines that show when I connect and onwards.
So to recap... the problem (in a nutshell) is that when I connect to the server/login, the server crashes.
Notes
- I am very new to MySQL so please, elaborate a little with the solution and try to resist flipping out on me because of a small mistake.
