cannot login to admin after php update to v5

Hi.

We have updated PHP to V5, and now zencart won't login to admin. We can still place orders and all, but when we try to login it just goes back to the login page without any error or message.

I can reinstall the whole zencart, but is there another way to work around this? We have orders pending and we cannot go though them.

Thanks

What version of Zen Cart is this?

1.3.7 without any mods.

If logins loop back to themselves without any error message, then you have session problems ... namely, PHP was unable to start a session based on the configuration options selected in your site.

how come it only started after we updated php?

also, any workaround to this without reinstalling zencart?

It's not uncommon to find hosts breaking their PHP session functionality when they upgrade their PHP.
Usually they've forgotten to properly enable session support, or have altered the settings (used defaults perhaps? instead of the previous settings which worked better?), or have not set permissions properly on the session.save temporary folder, or numerous other possible things.
The server administrator will probably have to be the one to fix your server's session problems.

Re-installing Zen Cart will not likely accomplish anything if the server's config is broken.

If that is the case tho, then all installations of zencart in the same server should be affected. However they are not. Existing 1.3.7 carts are affected, but new installs, both 1.3.7 and 1.3.8 work perfectly fine.

Either way, any idea how I can have this fixed without doing a reinstall?

Peek in the Free Add ons for the Debug tool and load that on your site as instructed and see what errors generated to see if this is a session issue ...

this is the error:

[15-Feb-2009 15:37:25] PHP Fatal error: Call to a member function Execute() on a non-object in /hsphere/local/home/user/domain.com/includes/functions/sessions.php on line 61

yeps that's the one ...

Are you both php 5 and MySQL 5 or just php 5?

just php5

...hey thanks again for the help guys!

Check the function files for sessions.php and compare them to the originals to make sure they are not changed ...

That is most likely where the problem is ...

i got it to work!!! woot! What i did was I copied the functions foloer in includes from another working site to the non-working site.

looks like some file got changed or corrupted somewhere in the functions folder.

all's working now.

thanks!!!!

Glad to hear things are working again ... most likely it was that sessions.php and updating it fixed the problem ...

I have something similar. I followed the advice above and the debug tool came up with:

[28-Apr-2009 16:45:08] PHP Fatal error: Call to a member function Execute() on a non-object in ****/includes/functions/sessions.php on line 72

I put in a new sessions.php but this just gave me 'illegal access'

I have not been able to get any input on upgrades on the server. Any because my admin is inaccessible I cannot find where to report what version of Zen cart I have. I think it is 1.2.6. It was fine until it just blanked out admin access and login stuff. So sounds like sessions but I don't know how to restore it.

Any input would be most welcome.

... and how do I move on from 'illegal access'?

Scratch that last one - I'm in again but back to the original problem as per the debug output.

In the session.php function files, add the php 5.x work around:

    function _sess_write($key, $val) {
      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;

      $expiry = time() + $SESS_LIFE;
      $value = $val;

      $qid = "select count(*) as total
              from " . TABLE_SESSIONS . "
              where sesskey = '" . zen_db_input($key) . "'";

      $total = $db->Execute($qid);

      if ($total->fields['total'] > 0) {
        $sql = "update " . TABLE_SESSIONS . "
                set expiry = '" . zen_db_input($expiry) . "', value = '" . zen_db_input($value) . "'
                where sesskey = '" . zen_db_input($key) . "'";

        return $db->Execute($sql);

      } else {
        $sql = "insert into " . TABLE_SESSIONS . "
                values ('" . zen_db_input($key) . "', '" . zen_db_input($expiry) . "', '" .
                         zen_db_input($value) . "')";

        return $db->Execute($sql);

      }
    }

You are a star. Doughnuts and coffee on their way.

Much thanks.

Thanks for the update that this fixed your issues with php 5 and the Execute error ... :smile:

And thank you kindly for the donuts and coffee!! We greatly appreciate the support to help keep Zen Cart humming along ... :cool:
