That's going to be abit long but why not.
I have coded my registration page to require a custom field.
This field is my users username in a game server I am running
In order to make sure they use their username I also added a script that checks if their password match the game password.
This part is working great.
Then, I added a php schedule task that connects to my sql game server and takes all the players info based on the field they used in registration and adding this info into Players user field category (let's say fields 6-15 10 player limit)
You can see this here:
Now, After this is working as it should, I am trying to pull more information but I want the members to be able to set a main player (one of the fields) so I can display other stuff like guild, profession etc
So to do this, I need to add another custom field called Main Player
the members would have to choose from the list of players contained in fields6-15 which one is their main player and this field will be used to pull more information
