Sorry for long title.
I have been trying for hours to get this thing to log out... no success.
I am using the form action $_SERVER('PHP_SELF') to send the info placed in the registration form.
All infor is validated and sent to database with no problem.
Once logged in the registration form goes and a logout button appears... Click on that and nothing happens. Code so far:
$db = new Database();
$newUser = new registrationSession($db);
$output = $username = $url = '';
if($_POST)
{
$validatedFields = new ValidatorSet();
//VALLIDATION STUFF DELETED
if($validatedFields->getErrors())
{
$username = $validatedFields->getItem('username')->getSanitisedValue();
$url = $validatedFields->getItem('URL')->getSanitisedValue();
$output = '<ul>';
foreach($validatedFields->getErrors() as $key=>$error)
{
$output .= '<li>' . $key . ': ' . $error . '</li>';
}
$output .= '</ul>';
}
else
{
$newUser->register($_POST['username'], $_POST['password'], $_POST['email'], $_POST['url'], $_POST['dob']);
}
if ($_POST['submit'] == 'logout')
{
$newUser->logout();
}
}
?>
//HTML NORMAL START STUFF DELETED
<body>
<h1>Assignment Task 3 - Registration Form</h1>
<p>To go to the members secure page you must be logged in, then click the below link:</p>
<p><a href="securePage.php">Go to secure page</a></p>
<p> If you are not a member please fill in the form below</p>
<section>
<?php
if(!$newUser->isLoggedIn())
{
?>
<form action="<?php $_SERVER['PHP_SELF']; ?>" method="post">
<fieldset>
<legend>Enter your registration details</legend>
<label for="username">Username: </label>
<input type="text" maxlength="20" required name="username" id="username">
<label for="password">Password: </label>
<input type="password" required name="password" id="password">
<label for="email">Email: </label>
<input type="email" required name="email" id="email">
<label for="url">Webpage URL: </label>
<input type="url" name="url" id="url">
<label for="dob">Date of birth (DD/MM/YYYY): </label>
<input type="date" required name="dob" id="dob">
</fieldset>
<button type="submit" name="submit" value="register" formnovalidate>Submit Details</button>
<?php
}
else
{
?>
<button type="submit" name="submit" value="logout">Logout</button>
</form>
<?php
}
?>
Code for the register(), loggedIn() and logout():
class registrationSession extends DatabaseSession {
public function register($username, $pass, $email, $url, $dob)
{
echo $username;
echo $pass;
echo $email;
echo $url;
echo $dob;
$parameters['fields'] = array('username', 'password', 'email', 'url', 'dob');
$parameters['table'] = 'userDetails';
$parameters['records'] = array(array($username, $pass, $email, $url, $dob));
$result = $this->dbConn->insert($parameters);
if($result)
{
session_regenerate_id();
$_SESSION["username"] = $username;
}
else
{
throw new Exception("Credentials not found");
}
}
public function logout()
{
$_SESSION = array();
if(ini_get("session.use_cookies"))
{
$params = session_get_cookie_params();
setcookie(session_name(), '', time() - 42000,
$params["path"], $params["domain"],
$params["secure"], $params["httponly"]);
}
session_destroy();
header("location: /Registration.php");
}
public function isLoggedIn()
{
return isset($_SESSION['username']);
}
}
