autoload_func.php error on fresh installation

[yuvallb]

I had this problem with an upgrade, and was not able to get rid of,
so I did a totaly fresh install, and it reappears:

The catalog pages always raise an error:
Fatal error: Call to a member function add_current_page() on a non-object in c:\domains\foo\wwwroot\includes\autoload_func.php on line 90

the admin works properly.

Database: MySQL 4.1.13
PHP Version: 5.1.2
HTTP Server: Microsoft-IIS/6.0

session.auto_start = Off

thanks.

I'm trying to install the latest zencart version: 1.3.6

That suggests that your /includes/classes/navigation_history.php file is corrupt or missing.

[yuvallb]

no, I've double and triple checked, I have the original distribution file.
I also read it, and it looks ok.

[yuvallb]

if it helps:
i added:

var_dump($_SESSION[$objectName]);

in line 90 of autoload_func.ph

and got:

object(__PHP_Incomplete_Class)#2 (4) { ["__PHP_Incomplete_Class_Name"]=> string(17) "navigationHistory" ["path"]=> array(1) { [0]=> array(4) { ["page"]=> string(5) "index" ["mode"]=> string(6) "NONSSL" ["get"]=> string(0) "" ["post"]=> array(0) { } } } ["snapshot"]=> array(0) { } ["observers"]=> array(0) { } }

in includes/autoload_func.php, lines 67-69:
if (isset($entry['checkInstantiated']) && $entry['checkInstantiated'] === true) {
if (!is_object($_SESSION[$objectName])) {
$_SESSION[$objectName] = new $className();

instead of:

if (isset($entry['checkInstantiated']) && $entry['checkInstantiated'] === true) {
if (!isset($_SESSION[$objectName])) {
$_SESSION[$objectName] = new $className();

please let me know if this is ok, or i'm missing soething else.

Sounds like your PHP configuration isn't handling sessions very well.

Perhaps you might consider installing XAMPP to use apache instead of bug-laden IIS?
This would also give you the added benefit of a server errorlog which would tell you more about what's going wrong with PHP.

[yuvallb]

thanks, I usually work on linux servers, but this belongs to someone else.
anyway - it did not solve the problem, because now the shopping cart class get instantiated every request, so its not persistant...

[DrByte]

Yes -- running these kinds of systems on home PC's using wannabe webserver engines is often problematic.

I'm sure if you installed it to a Linux server, esp if it's configured as a common webserver, you'd have fewer problems :)

Im running into this same error, but my situation is not like the previous poster with the Windows server. I am using a Unix based platform with Apache web server.

Error occurs only when visiting the site at index.php (not when using admin, which works fine).

Fatal error: Call to a member function on a non-object in /export/spare/local/sites/runaraven.com/htdocs/includes/autoload_func.php on line 90

Any suggestions on what to look for? I did check to be sure the navigation_history.php file is present.
