vb.org Archive - Miscellaneous Hacks - [DBTech] Username Change v1 (vB4)

Here's the script I made/used to go from Marco's name change mod to this one.

PHP Code:


		
			
<?php



// Change this stuff



$dbhost = 'host';

$dbuser = 'user';

$dbpass = 'pass';

$dbname = 'table';



// END OF STUFF TO CHANGE



$mysqli = new mysqli($dbhost, $dbuser, $dbpass, $dbname);



if($mysqli->connect_error) {

   die("Connect Error: " . $mysqli->connect_error);

}



// Get current usernames for users that have changes

$result = $mysqli->query("SELECT distinct mh_unm_history.userid, user.username FROM mh_unm_history, user WHERE user.userid = mh_unm_history.userid");

while ($row = $result->fetch_row()) {

   $usernames[$row[0]] = mysql_real_escape_string($row[1]);

}

$result->free_result();



// Get the username changes

$result = $mysqli->query("SELECT * from mh_unm_history ORDER BY userid ASC, dateline DESC");

while ($row = $result->fetch_row()) {

   $userid = $row[0];

   $dateline = $row[1];

   $oldname = mysql_real_escape_string($row[2]);

   $adminid = $row[3];

   $uniq = md5($dateline . $userid . $userid . rand(1111,9999));



   // Build the array of queries we'll execute later

   $q[] = "INSERT INTO userchangelog VALUES('', $userid, 'username', '$usernames[$userid]', '$oldname', $adminid, $dateline, '$uniq')";



   // Set the username as the old one in the

   // event there are multiple name changes

   $usernames[$userid] = $oldname;

}



foreach ($q as $query) {

   if (!$mysqli->real_query($query))

      echo "FAILED: " . $query . "<br>\n"; 

}



$result->close();

$mysqli->close();

?>

Things I know will cause issues: if you don't have the mysqli (notice the i) extension or use a prefix on your forum tables.

You're on your own to backup/test/verify/etc the above code will work for you!
