problem with a while loop maybe?

[Spring]

This is the email verification script im using..

 

//email verify
$activationKey =  mt_rand() . mt_rand() . mt_rand() . mt_rand() . mt_rand();
$sql="INSERT INTO account_info (activation_key, status) VALUES ('$activationKey', 'verify')";

if (!mysql_query($sql)){

exit('Error: ' . mysql_error());
}

else {



//Send activation Email

$to = $_POST['email'];
$subject = "NarutoRPG.com Registration";
$message = "Welcome to our website! You, or someone using your email address, has completed registration at narutoRPG.com. You can complete registration by clicking the following link:\rhttp://www.arzania.com/verify.php?$activationKey\r\r If this is an error, ignore this email and you will be removed from our mailing list.\r\rRegards,\ narutoRPG.com Team";
$headers = 'From: ashyiscool2@gmail.com' . "\r\n" .
'Reply-To: ashyiscool2@gmail.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);

//User isn't registering, check verify code and change activation code to null, status to activated on success

$queryString = $_SERVER['QUERY_STRING'];
$query = "SELECT * FROM account_info";
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($result)){
if ($queryString == $row["activation_key"]){
echo "Congratulations!" . " " . $row["username"] . " is now the proud new owner of a NarutoRPG.com account. Login to begin to play.";
$sql="UPDATE account_info SET activation_key = '', status='activated' WHERE (id = $row[id])";
if (!mysql_query($sql))

{

        die('Error: ' . mysql_error());

  }

    }

  }
}
}



include "footer.php";
?>

 

For some reason, when the person is registered it shows everyones name who registered, for example..

 

You've been successfully registered!Congratulations! tonyhh is now the proud new owner of a NarutoRPG.com account. Login to begin to play.Congratulations! tonyh is now the proud new owner of a NarutoRPG.com account. Login to begin to play.Congratulations! tony is now the proud new owner of a NarutoRPG.com account. Login to begin to play.etc...etc..

 

How can you make it only repeat the users name who registered, not everyone?

[doddsey_65]

$query = "SELECT * FROM account_info";

 

you are selecting everyone from account_info

 

try:

 

$query = "SELECT * FROM account_info WHERE username = '".$_POST['username']."'";

 

that will make sure you are only selecting the user who registered by pulling what they added in the username field
