Well, it's probably me that's confused. I have an authenticate()
function which should start a session and if the user is not logged in
then show the login screen otherwise return after storing and
registering a user object in a session variable. This object has
accessor methods to get the login name, access level, etc... This seems
to work okay--within the authenticate function I can access the object
in the HTTP_SESSION_VARS array. But as soon as I return to the main
script it's gone. I must be doing something wrong with the scoping, but
I can't see what. Any thoughts? Here's the code:
<?php
/* --------- */
/* index.php */
/* --------- */
require_once('ucautho/ucautho.inc');
authenticate();
print("From index testUser: " . $testUser->getLogin() . "<br>\n");
print("From index HTTP_SESSION_VARS['ucAuthoUser']: ");
print($HTTP_SESSION_VARS['ucAuthoUser']->getLogin() . "<br>\n"); //this
is line 12
?>
<?php
/* ------------------- */
/* ucautho/ucautho.inc */
/* ------------------- */
function authenticate($appName="") {
global $HTTP_SESSION_VARS, $HTTP_POST_VARS;
global $testUser;
session_name("UCAutho");
session_start();
if (isset($HTTP_SESSION_VARS['ucAuthoUser']) &&
$HTTP_SESSION_VARS['ucAuthoUser']->isValid()) {
return;
} else {
if (isset($HTTP_POST_VARS['authoSubmit'])) {
$HTTP_SESSION_VARS['ucAuthoUser'] =&
new
UcAuthoUser($HTTP_POST_VARS['authoLogin'],$HTTP_POST_VARS['authoPword']);
if ($HTTP_SESSION_VARS['ucAuthoUser']->isValid()) {
session_register('ucAuthoUser');
$testUser = $HTTP_SESSION_VARS['ucAuthoUser'];
print("From authenticate testUser: " .
$testUser->getLogin() . "<br>\n");
print("From authenticate
HTTP_SESSION_VARS['ucAuthoUser']: ");
print($HTTP_SESSION_VARS['ucAuthoUser']->getLogin() .
"<br>\n");
return;
}
}
showLogin($appName);
}
}
/* more functions and the class declaration snipped */
?>
Here's what I get when I login as 'steve' with a good password:
From authenticate testUser: steve
From authenticate HTTP_SESSION_VARS['ucAuthoUser']: steve
From index testUser: steve
From index HTTP_SESSION_VARS['ucAuthoUser']:
Fatal error: Call to a member function on a non-object in
/home/httpd/html/ucdamage/index.php on line 12
Note the testUser works in both instances, the session var only works
inside the function.
