eBay Login Page

rtcl10 · 09-06-2007, 05:49 AM

Hiya Guys,

How do I create a Login Page like eBay using sessions, where users click a "Sign-In" link, available on any page (e.g. Main.html), resulting in the page relocating to the Login Page (Login.html).

Upon a user signing in, the Sign-In link page (e.g. Main.html) previously displayed reappears, displaying the users username, along with a "Logout" link.

Upon the users selecting logout (again available on anyway page), the user is redirected to the previously display page.

The following code is what I have currently:

Main.html

Code:

<html>
<head>
<title></title>
</head>

<body>
Sign-In
</body>
</html>

Login.html

Code:

<html>
<head>
<title></title>
</head>

<body>
<form action="Login.php" method="post">
  <label>Username:</label>
  <input name="Username" type="text" id="Username">
  <br>
  <br>
  <label>Password:</label>
  <input name="Password" type="text" id="Password">
  <br>
  <br>
  <input type="submit" name="Submit" value="Submit">
</form>

</body>
</html>

In your login.php page you'd have a setting of your session cookie, which will hold the login accept, and after that you'd have a small delay, followed by a header redirect to "http://".$HTTP_HOST.$REQUEST_URI

you could either use sessions, or put the destination in a hidden value of the form.

in PHP, $_SERVER['HTTP_REFERER'] returns the previous page the user came from. this example uses the method of embedding the destination in the form.

login.php

PHP Code:


			
<?php
// process the login and re-direct if necessary
if ($_POST) {
// login logic goes here

  if ($successful login) {
    if ($_POST['destination']) {
      $destination = $_POST['destination'];
    } else {
      $destination = "my_default_page.htm";
    }

    // this forwards the user to the proper page
    header("location: ".$destination);
    exit; 
  }
}
?>
<html>
<head>
<title></title>
</head>

<body>
<form action="Login.php" method="post">
<input type="hidden" name="destination" value="<?php echo $_SERVER['HTTP_REFERER']; ?>" />
  <label>Username:</label>
  <input name="Username" type="text" id="Username">
  <br>
  <br>
  <label>Password:</label>
  <input name="Password" type="text" id="Password">
  <br>
  <br>
  <input type="submit" name="Submit" value="Submit">
</form>

</body>
</html>
