Hi, I am trying to make a login script that uses the user's id from the database, and tries to match it up with the user and password sent by the login form. My checklogin.php page, just jumps back to the index.php page for some reason. I don't know why. I get the following errors, any help greatly appreciated. thank you.

 

Notice: Undefined index: myusername in /hermes/bosweb/web173/b1739/public_htmlchecklogin.php on line 19

 

Notice: Undefined index: mypassword in /hermes/bosweb/web173/b1739/public_html/checklogin.php on line 20

Wrong Username or Password

 

Here is my code to check the id. I can't figure out what is wrong.

 

<?php 

ini_set ("display_errors", "1");
error_reporting(E_ALL);
$host		= "";
$database 	= "";
$username 	= "";
$password 	= ""; 
$tbl_name   = "users";
$conn = mysql_connect($host, $username, $password) or die("Could not connect: " . mysql_error());

if($conn)
{
mysql_select_db($database);
} else {
	echo "failed to select database";
}	
// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$sql="SELECT id FROM $tbl_name WHERE username='$myusername' and password= SHA1('$mypassword')";
$result=mysql_query($sql);
$query_data = mysql_fetch_row($result);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result)
;
// If result matched id, table row must be 1 row
if($count==1){
session_start();

     $_SESSION['userid']=$query_data[0];


header("location:login_success.php");
}

else {
echo "Wrong Username or Password";
}

?>

Awesome, thank you so much!! It works. It's alive! muwahah. thank you. :-* :-* :-*

Also, does anyone know if I should do the "password reset by email" script now, or the "access levels" for the accounts now instead? I am not sure which one to do. Any advice greatly appreciated. thanks.
