Question

我尝试连接到db，authenficate，如果可以重定向到成功页面....

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

// username and password sent from form 
$myusername=$_POST['username']; 
$mypassword=$_POST['password']; 

// 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 * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);

// Mysql_num_row is counting table row
$count=mysql_num_rows($result);

// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){

  $_SESSION['username']=$myusername;
  $_SESSION['password']=$mypassword;

  header("location:login_success.php");
}
else {
  echo "Wrong Username or Password";
}

在我的login_success.php脚本中，我有

<?php
session_start();
if(!isset($_SESSION['username'])){
header("location:main_login.php");
}
?>

<html>
<body>
Login Successful
</body>
</html>

我尝试使用错误的用户名，密码我得到＆＃34;错误的用户名或密码＆＃34;

如果我使用了良好的密码，请转到main_login.php ...
