Fatal error: Call to a member function on a non-object in

Hi all,

I am trying to get phpBB's login on my Wordpress blog. I created a simple login file which works.


When I try to include this file in Wordpress I get the following error:

Fatal error: Call to a member function on a non-object in 
/path_to/sessions.php on line 134

Code (markup):

$sql = 'SELECT *
			FROM ' . USERS_TABLE . '
			WHERE user_id = ' . (int) $user_id;
	
		if (!($result = $db->sql_query($sql)))
		{
			message_die(CRITICAL_ERROR, 'Error doing DB query userdata row fetch', '', __LINE__, __FILE__, $sql);
		}
		$userdata = $db->sql_fetchrow($result);
		$db->sql_freeresult($result);

Code (markup):

Line 134: if (!($result = $db->sql_query($sql)))

I already tried to add global $db; no luck

Any other suggestions??

 

probably you added a mod and you forgot to update the tables.

Some mods come with the tables required to alter the database, some others need a manual setting.

If you have a backup of the original database before the mod, dump it again and start from zero making the database alteration first.

This can also be the result of upgrading the script, check this out:

To continue on from what digitalpoint said, are you sure that you've included the file that declares $db correctly?

 

Tx guys for your answers

hmm, I did some phpbb modifications but these modifications work correct. I mean my phpBB forum works fine. I had a clean start with phpbb 2.02 (the latest). My modifications are just for SEO.

Calling the simple login page works fine also.

Including the simple login page in WP enviroment causes a problem.

I have read a lot about this subject, apparently a well known issue between WP and phpBB. I read it could be "a query being called outside the session function".

Trying to grasp this problem, at the start of this particular function I see

function session_begin($user_id, $user_ip, $page_id, $auto_create = 0, $enable_autologin = 0, $admin = 0)
{
	global $db, $board_config;
	global $HTTP_COOKIE_VARS, $HTTP_GET_VARS, $SID;
........
........

Code (markup):

As my phpbb works fine I guess $db is instantiated well

Could it be WP and phpBB are using the same named globals, which conflicts???

Any suggestions??
