How can I save a users IP in an external text file within my code? The purpose of my code is to save the users IP address when they input the wrong login details into my script. As you can see from my code it doesn’t output the IP as the link between when the user inputs the wrong details to the text file isn’t correctly set up. Can someone help me with doing this please?
saveLog(getBrowser(),'log.txt'); This code doesn’t seem to of successfully store the users IP after they input the wrong login details as the text file is empty.
else
{
$_SESSION['login'] = "";
echo "Invalid username or password, your information has been logged.";
//here the login failed
saveLog(getBrowser(),'log.txt');
?>
}
<?php
//removing the errors/warnings from the page
if(isset($_POST['submit'])){
$user = $_POST["username"];
$pass = $_POST["password"];
$validated = false;
session_start();
$_SESSION['login'] = "";
if($user!="" && $pass!="")
{
$conn = @mysql_connect ("localhost", "root", "") or die ("Sorry - unable to connect to MySQL database.");
$rs = @mysql_select_db ("users",$conn) or die ("error");
$sql = "SELECT * FROM user WHERE username = '$user' AND password ='$pass'";
$rs = mysql_query($sql,$conn);
$result = mysql_num_rows($rs);
if ($result > 0) $validated = true;
if($validated)
{
$_SESSION['login'] = "OK";
$_SESSION['username'] = $user;
$_SESSION['password'] = $pass;
header('Location: protectedData.php');
}
else
{
$_SESSION['login'] = "";
echo "Invalid username or password, your information has been logged.";
}
}
else $_SESSION['login'] = "";
}
?>
