Fatal error: Call to a member function Execute() on a non-object

[OLDTango]

I have had this error for a while now, but haven't had the time to attempt to fix it. I decided to go ahead and set up a new ZenCart site, and work on some custom templates. However I can't log into the admin section at all. The admin login screen and the cart front page both display this error.

Fatal error: Call to a member function Execute() on a non-object in /var/www/localhost/htdocs/catalog/includes/functions/sessions.php on line 61

This is the line in question in the above mentioned file.

line 61 ### $total = $db->Execute($qid);

I am not sure how to fix this error and have re-installed several times always getting the same error.

Can this be a problem with php or mysql. I am running php-5.2.2 and mysql-5.0.44. It seems that this problem started with some system updates a little while back.

TIA................................

It seems you're using an older version of Zen Cart on a newer version of PHP.

What Zen Cart version did you install?

It seems you're using an older version of Zen Cart on a newer version of PHP.

What Zen Cart version did you install?

The Version I have installed is 1.3.7 which appears to be the latest version. I don't remember if I installed the adim patch or not, it's been awhile. I will download a fresh copy of the latest patched version and do a clean install.

Dr Byte I'm getting the very same error since moving across to a new server.

Upgrading to the newer version is something I'd like to avoid right at the moment as my 'customisations' weren't written as portably as I would have liked.

Any advice?

from the version.php file..

Major Version 1..

Minor version.. 3.0.2

Is your new server running a different PHP version ?

You're probably experiencing the PHP5.2 incompatibility problems others have had when using ZC versions prior to v1.3.6 (where a workaround was added to handle a PHP 5.2 quirk). The fix is documented elsewhere on the forums: http://www.zen-cart.com/forum/showth...534#post287587


Or there are other thoughts discussed here:

Thanks DrByte - that fix worked perfectly.

For others that have stumbled across this thread via a search as I did, DrBytes Solution is below -

b. edit /includes/functions/sessions.php and /admin/includes/functions/sessions.php

Code:
function _sess_write($key, $val) {
global $db;
global $SESS_LIFE;

change to:

Code:
function _sess_write($key, $val) {
// The following is only to work around a PHP 5.2.0 bug:
global $db;
if (!is_object($db)) {
//PHP 5.2.0 bug workaround ...
$db = new queryFactory();
$db->connect(DB_SERVER, DB_SERVER_USERNAME, DB_SERVER_PASSWORD, DB_DATABASE, USE_PCONNECT, false);
}

global $SESS_LIFE;Option (b) may or may not be "complete", and has only had preliminary testing. The best fix will be to have PHP fix their bug, of course.
