Here are my tables:

UPDATED ANSWER. simplified the question:

Table 1

 ControlPanelID
 UserDescription
 ChannelCommentsID  
 UserID

Table 2

UserID
UserName
Password
Email
Reputation
ControlPanelID
Role

Here are my 3 insert Statements:

$queryString=
            "INSERT INTO ControlPanel VALUES("",ChannelCommentsID , userID)".
            "INSERT INTO users VALUES($userNam,$pass,$email, ,'anonym')";

I want the UserID row to increment in both tables..how is that being acheived?

in other words opening the connection to the database twice… (i.e. 2 queries)?

Answer 1

You may use LAST_INSERT_ID() to get the value of the AUTOINCREMENT column for the previous INSERT.

In your specific case, this may be a possible solution

$queryString=
    "INSERT INTO users VALUES($userNam,$pass,$email, ,'anomy')".
    "INSERT INTO ControlPanel VALUES("",ChannelCommentsID , LAST_INSERT_ID())";
