eBay Login Screen

**TicTac** · Aug 20, 2007 11:06

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>

Store the URL of the current page in a PHP session variable, or pass it to the login page via query string (login.html?url=main.html). On the Login page, grab the URL passed to it (via session or query string) and save it as a hidden form field or through another session variable. Once the login form is submitted and you verify the username/password is valid, take the URL from wherever you stored it and redirect back

Code:

header("Location: $url");

Have you any way to store your users yet? Have you setup a database?

Yes, using the following code:

Create Table/Database:

Code:

<?php
$con = mysql_connect("localhost","Username","Password");
if (!$con)
{
  die(mysql_error());
}

// Create database
if (mysql_query("CREATE DATABASE WB",$con))
{
  echo "Database Created!";
}
else
{
  echo mysql_error();
}

// Create table in WB database
mysql_select_db("WB", $con);
$sql = "CREATE TABLE Users 
(
  ID int not null auto_increment,
  Username text,
  Password text,
  primary key(ID)
)";
mysql_query($sql,$con);

mysql_close($con);
?>

Add New User (New.html):

Code:

<html>
<body>

<form action="New.php" method="post">
<h2>Add User</h2>
Username: <input type="text" name="Username" />
Password: <input type="text" name="Password" />
<input type="submit" />
</form>

</body>
</html>

Add New User (New.php):

Code:

<?php
$con = mysql_connect("localhost","Username","Password");
if (!$con)
{
  die(mysql_error());
}

mysql_select_db("WB", $con);

$sql="INSERT INTO Users (Username, Password)
VALUES
('$_POST[Username]','$_POST[Password]')";

if (!mysql_query($sql,$con))
{
  die(mysql_error());
}
echo $_POST[Username] . "'s Account Created Successfully!";

mysql_close($con)
?>

Now What?
