Input Form

• 1). Using your HTML editor or notepad, create a new Web page and save it as "login.php". Create a form and use the "post" method value. Example code follows:
  
  <form action="login.php" method="post">
  
  </form>
  
  
• 2). Add two input boxes within the form for the username and password fields. Use the "password" type for the password box. Example code follows:
  
  <form action="login.php" method="post">
  
  <input type="text" name="username">
  
  <input type="password" name="password">
  
  </form>
  
  
• 3). Add a submit button which will be used to submit the form. Example code follows:
  
  <input type="submit" value="Submit">
  
  

PHP Code

• 1). Declare two variables that will hold the values from the form submission. Call them "username" and "password". Example code follows:
  
  <?php
  
  $username = $_POST['username']
  
  $password = $_POST['password']
  
  ?>
  
  
• 2). Write an "if" statement to check if the form has been submitted. The code for this is:
  
  if($_SERVER['REQUEST_METHOD'] == "POST") {
  
  }
  
  
• 3). Write an "if" statement to check the username and password against two values of your choice. Include the "header" statement to redirect the user accordingly. Example code follows:
  
  if ($username == "user" && $password == "pass"){
  
  header('Location: http://www.example.com/success.html');
  
  die();
  
  else
  
  {
  
  header('Location: http://www.example.com/loginfailed.html');
  
  die();
  
  }
