Prevent people making multiple accounts

This is hard to believe, but some people are desperate as to keep registering accounts to level up their adoptables. Let's make this method of leveling up not worth it.

Step 1:

Run this query

PHP Code:


		
			
ALTER TABLE users ADD (ip VARCHAR(30) NOT NULL DEFAULT "0")

Step 2:

Open register2.php

Find

PHP Code:


		
			
// Connect to our database

Above this line, put

PHP Code:


		
			
$ip = $_SERVER['REMOTE_ADDR']; 

$ip = preg_replace("/[^a-zA-Z0-9@._-]/", "", $ip);

Step 3:

Still in register2.php, find this code:

PHP Code:


		
			
//Check that username does not already exist



$query = "SELECT * FROM users WHERE username = '$username'";

$result = @mysql_query($query);

$num = @mysql_numrows($result);



//Loop out code

$i=0;

while ($i < 1) {



$luser=@mysql_result($result,$i,"username");





$i++;

}



$luser = strtolower($luser);

$u2 = $str = strtolower($username);



if($luser == $u2){

$template = replace(':ARTICLETITLE:','Error',$template);

$template = replace(':ARTICLECONTENT:','Your username has been taken.  Please <a href="register.php">go back</a> and select a different username.',$template);

echo $template;

die();

}

Below all of that, put

PHP Code:


		
			
// Check that user is not making multiple accounts



$query = "SELECT * FROM users WHERE ip = '$ip'";

$result = @mysql_query($query);

$num = @mysql_numrows($result);



//Loop out code

$i=0;

while ($i < 1) {



$ip2=@mysql_result($result,$i,"ip");





$i++;

}



if($ip == $ip2){

$template = replace(':ARTICLETITLE:','Error',$template);

$template = replace(':ARTICLECONTENT:','You are not allowed to make multiple accounts.',$template);

echo $template;

die();

}

Step 4:

Find this line

PHP Code:


		
			
//All checks pass, create the user

Insert below it:

PHP Code:


		
			
$pass1 = md5($pass1); //MD5 the password

mysql_query("INSERT INTO users VALUES ('', '$username', '$pass1','$email','free', '$ip')");

Note: if you have installed my currency mod, you'll want to insert this instead:

PHP Code:


		
			
$pass1 = md5($pass1); //MD5 the password

mysql_query("INSERT INTO users VALUES ('', '$username', '$pass1','$email','free', '0', '$ip')");
