php/mysql auto logout after 2 hour and reset password

Posted on 16th Feb 2014 07:03 pm by admin

Hi all,

This I hope will make sense. I've the following code which when a user logins in, creates a session:


if (isset($_POST['submitted'])) { // Check if the form has been submitted.

require_once ('mysql_connect.php'); // Connect to the database.

// Validate the email address.
if (!empty($_POST['email'])) {
$e = escape_data($_POST['email']);
} else {
echo '<p class="error">You forgot to enter your email address!</p>';
$e = FALSE;
}

// Validate the password.
if (!empty($_POST['pass'])) {
$p = escape_data($_POST['pass']);
} else {
$p = FALSE;
echo '<p class="error">You forgot to enter your password!</p>';
}

if ($e && $p) { // If everything's OK.

// Query the database.
$query = "SELECT user_id, first_name, account_id FROM users WHERE (email='$e' AND pass=SHA('$p')) AND active IS NULL";
$result = mysql_query ($query) or trigger_error("Query: $queryn<br />MySQL Error: " . mysql_error());

if (@mysql_num_rows($result) == 1) { // A match was made.

// Register the values & redirect.
$row = mysql_fetch_array ($result, MYSQL_NUM);
mysql_free_result($result);
mysql_close(); // Close the database connection.
$_SESSION['user_id'] = $row[0];
$_SESSION['first_name'] = $row[1];
$_SESSION['account_id'] = $row[2];

// Start defining the URL.
$url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']);
// Check for a trailing slash.
if ((substr($url, -1) == '/') OR (substr($url, -1) == '\') ) {
$url = substr ($url, 0, -1); // Chop off the slash.
}

// Add the page.
$url .= '/index.php';

ob_end_clean(); // Delete the buffer.
header("Location: $url");
exit(); // Quit the script.

} else { // No match was made.
echo '<p class="error">Either the email address and password entered do not match those on file or you have not yet activated your account.</p>';
}

} else { // If everything wasn't OK.
echo '<p class="error">Please try again.</p>';
}

mysql_close(); // Close the database connection.

} // End of SUBMIT conditional.
?>

<h1>Login</h1>
<p class="maintext">Your browser must allow cookies in order to log in.</p>
<form action="login.php" method="post">
<fieldset>
<p class="maintext"><b>Email Address:</b> <input type="text" name="email" size="20" maxlength="40" value="<?php if (isset($_POST['email'])) echo $_POST['email']; ?>" /></p>
<p class="maintext"><b>Password:</b> <input type="password" name="pass" size="20" maxlength="20" /></p>
<div align="center"><input type="submit" name="submit" value="Login" /></div>
<input type="hidden" name="submitted" value="TRUE" />
</fieldset>
</form>


Each page I want protected then has this at the top


// If no first_name variable exists, redirect the user.
if (!isset($_SESSION['first_name'])) {

// Start defining the URL.
$url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']);
// Check for a trailing slash.
if ((substr($url, -1) == '/') OR (substr($url, -1) == '\') ) {
$url = substr ($url, 0, -1); // Chop off the slash.
}
// Add the page.
$url .= '/index.php';

ob_end_clean(); // Delete the buffer.
header("Location: $url");
exit(); // Quit the script.

} else {
### page ###
}


What I'd like to do is set the session to automatically expire after 2 hours and the users password to reset to something different to prevent login.

I assume this is possible but where do I start?
