你想要一个代码？什么阻止你写一个？ – mins 2015-04-01 05:49:52

你没有说你想要一个代码，并没有告诉我们你做了什么 - 你呢？ – Terabyte 2015-04-01 05:55:12

THE HTML CODE: 
<html> 
    <head> 
     <title>Login page</title> 

<style> 
body{ background-image: url("wall0003.png"); 
width: 200%; 
height: 200%; 
background-position: top; 
background-repeat: no-repeat;} 

</style> 
</head> 
<body text="black" align="left"> 
     <form action="connectivity.php" onsubmit="post"> 
<br/> 
<br/> <br/> 
<br/> <br/> <br/> <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/> 
      User 
     <input type="text" name="userid"/> <br/><br/> 
      Pswd<input type="password" name="pswrd"/> <br/><br/> 
      <input type="submit" value="Login" name="Login"/> 
      <input type="reset" value="Cancel"/> 
     </form> 
<script language="javascript"> 
      function check(form) { 
/*function to check userid & password 
       the following code checkes whether the entered userid and password are matching*/ 
       if(form.userid.value == "myuserid" && form.pswrd.value == "mypswrd") 
{ 
        window.open('target.html')  //opens the target page while Id & password matches 
       } 
       else { 
        alert("Error Password or Username") // displays error message 
       } 
      } 
     </script> 
    </body> 
</html> 

PHP CODE: 
<?php 
define('DB_HOST', 'localhost'); 
define('DB_NAME', 'practice'); 
define('DB_USER','root'); 
define('DB_PASSWORD','admin'); 

$con=mysql_connect(DB_HOST,DB_USER,DB_PASSWORD) or die("Failed to connect to MySQL: " . mysql_error()); //connect to mysql 
$db=mysql_select_db(DB_NAME,$con) or die("Failed to connect to MySQL: " . mysql_error()); //select a mysql database 
/* 
$ID = $_POST['user']; 
$Password = $_POST['pass']; 
*/ 
function SignIn() 
{ 
session_start(); //starting the session for user profile page 
if(!empty($_POST['user'])) //checking the 'user' name which is from login.html...is it empty or has some text? 
{ 
    $query = mysql_query("SELECT * FROM UserName where userName = '$_POST[user]' AND pass = '$_POST[pass]'") or die(mysql_error());//send mysql query to the database 
    $row = mysql_fetch_array($query) or die(mysql_error()); //fetch a row result 
    if(!empty($row['userName']) AND !empty($row['pass'])) 
    { 
     $_SESSION['userName'] = $row['pass']; 
     echo "SUCCESSFULLY LOGIN TO USER PROFILE PAGE..."; 

    } 
    else 
    { 
     echo "SORRY... YOU ENTERD WRONG ID AND PASSWORD... PLEASE RETRY..."; 
    } 
} 
} 
if(isset($_POST['submit'])) 
{ 
    SignIn(); 
} 

?>
