I get this error when I click the login link on my home page.

Code: Select all

<?php 

include 'dbc.php';

$err = array();

foreach($_GET as $key => $value) {
	$get[$key] = filter($value); //get variables are filtered.
}

if ($_POST['doLogin']=='Login')
{

foreach($_POST as $key => $value) {
	$data[$key] = filter($value); // post variables are filtered
}


$user_email = $data['usr_email'];
$pass = $data['pwd'];


if (strpos($user_email,'@') === false) {
    $user_cond = "user_name='$user_email'";
} else {
      $user_cond = "user_email='$user_email'";
    
}

	
$result = mysql_query("SELECT `id`,`pwd`,`full_name`,`approved`,`user_level` FROM users WHERE 
           $user_cond
			AND `banned` = '0'
			") or die (mysql_error()); 
$num = mysql_num_rows($result);

  // Match row found with more than 1 results  - the user is authenticated. 
    if ( $num > 0 ) { 
	
	list($id,$pwd,$full_name,$approved,$user_level) = mysql_fetch_row($result);
	
	if(!$approved) {
	//$msg = urlencode("Account not activated. Please check your email for activation code");
	$err[] = "Account not activated. Please check your email for activation code";
	
	//header("Location: sessionlogin.php?msg=$msg");
	 //exit();
	 }
	 
		//check against salt
	if ($pwd === PwdHash($pass,substr($pwd,0,9))) { 
	if(empty($err)){			

     // this sets session and logs user in  
       session_start();
	   session_regenerate_id (true); //prevent against session fixation attacks.

	   // this sets variables in the session 
		$_SESSION['user_id']= $id;  
		$_SESSION['user_name'] = $full_name;
		$_SESSION['user_level'] = $user_level;
		$_SESSION['HTTP_USER_AGENT'] = md5($_SERVER['HTTP_USER_AGENT']);
		
		//update the timestamp and key for cookie
		$stamp = time();
		$ckey = GenKey();
		mysql_query("update users set `ctime`='$stamp', `ckey` = '$ckey' where id='$id'") or die(mysql_error());
		
		//set a cookie 
		
	   if(isset($_POST['remember'])){
				  setcookie("user_id", $_SESSION['user_id'], time()+60*60*24*COOKIE_TIME_OUT, "/");
				  setcookie("user_key", sha1($ckey), time()+60*60*24*COOKIE_TIME_OUT, "/");

				   }
		  header("Location: myaccount.php");
		 }
		}
		else
		{
		//$msg = urlencode("Invalid Login. Please try again with correct user email and password. ");
		$err[] = "Invalid Login. Please try again with correct user email and password.";
		//header("Location: login.php?msg=$msg");
		}
	} else {
		$err[] = "Error - Invalid login. No such user exists";
	  }		
}

Check the form, this error refers to a value that isn't present in the $_POST array;

Code: Select all

<?php
if ($_POST['doLogin']=='Login') // <-- $_POST['doLogin'] isn't present but the code tries to access it
?>
