Session Variables!

Thanks to peterx for describing this function! It was exactly what I needed, and only took 5 pages of search to find it! A good one for the handbook.
Drupal session variables must be arrays!

$_SESSION['xyz'] = array();
Thx peterx. Note the addition of an array to the session global. You cannot use scalars, as they won't be recognized (or stored) by Drupal, and you'll scratch your head wondering why your session variable isn't getting updated. E.g. this won't work:
$_SESSION['xyz'] = 'fred';
来自 https://drupal.org/node/33513
普通分类:
$_SESSION['xx'] = value;
Sessions are started in session.inc which is loaded by boostrap.inc which is almost the first thing done in index.php. You should be able to access session variables everywhere in your code using the $_SESSION array. If you are building theme xyz then set up the following code.
<?phpif(!isset($_SESSION['xyz']))
{
$_SESSION['xyz'] = array();
}
$xyz = & $_SESSION['xyz'];
?>
When you want to store variable z from page to page you can use the following code.
<?php$xyz['y'] = $y;
?>
On the next page you can access $y using the following code.
<?php$y = & $xyz['y'];
?>
Are you experienced at using & to create references?
