Session Variables in Wordpress

I'm trying to create session variables in Wordpress and have discovered that Wordpress does not really do this. I found a plugin Called WP_Sessions and it is said to help create sessions.  How you use it is as follows:
$wp_session = WP_Session::get_instance();
$wp_session['user_name'] = 'User Name';                            // A string
$wp_session['user_contact'] = array( 'email' => 'user@name.com' ); // An array
$wp_session['user_obj'] = new WP_User( 1 );                        // An objec

Open in new window


OK, I want to store a field from a form.
<input type="text" name="addon-28-bicycle-info[manufacturer]" id="addon-28-bicycle-info[manufacturer]"  value="<?php  if(isset($_POST['addon-28-bicycle-info']['manufacturer'])) {echo $_POST['addon-28-bicycle-info']['manufacturer'];}  ?>" >

Open in new window

How do I store that field as a session variable after the form is submitted?
Here is a link to the plugin:

You don't need a plugin and its overhead for this.  Just add the following code to functions.php:

add_action('init', 'myStartSession', 1);
function myStartSession() {
    if(!session_id()) {
        session_start();
    }
}

Open in new window


This will allow sessions in WordPress and standard PHP notation from there.

The can I do something like the following to pass the variable from page to page?
$_SESSION['bv'] = $_POST['bike_value'];
$_SESSION['manu'] = $_POST['addon-28-bicycle-info[manufacturer]'];

Do those  need to be in the head?

The head of what?  PHP code is independent of HTML structures.  Traditionally, we have constructed PHP pages like so:

<?php
 blah; 
 blah; 
 blah;
?>
<html>
<head></head>
<body>
<?php echo $somevar ?>
</body>
</html>

Open in new window


But there's no difference between that and this:

<html>
<head></head>
<body>
<?php
 blah; 
 blah; 
 blah;
 echo $somevar; 
?>
</body>
</html>

Open in new window


So long as the variables are declared before they are used, you should be okay.
