Fatal error: Call to a member function

[fixer]

it is a script which show the last 10 threads on wherever you want.
it was working fine on vb3.0.7
but now it does not.

i fixed many errors but this one make me crazy

this is what i ve got:

Fatal error: Call to a member function query_first() on a non-object in c:\AppServ\www\vb350gold\ana\lastsetup.php on line 1903

and this is the code of that line

$childsets = $db->query_first("
SELECT styleid, title, parentlist
FROM " . TABLE_PREFIX . "style
WHERE parentid = $styleid
");

It means that $db isn't an object.

If that code is within a function, make sure that $db has been globaled. Alternativly, check if $vbulletin has been globaled, and use $vbulletin->db->query_first(...

Could you explain the globaled thing?

Here is a query I have that gives that same error:

$trails=$DB_site->query("SELECT * FROM conditiontrail ORDER BY trailid ASC");

Globalizing is making the scope of a variable global, instead of only to the current function. To globalize a variable you can use the following syntax:

global $myvar; 

To answer the question in your first post, $db is probably pout of scope in the function where you are using it. Try using $vbulletin->db->query_first instead. If that still don't work, add a 'global $vbulletin;' on a line before this.

In your second post your are using '$DB_site'. This is vB3.0.x syntax. This is in vB3.5 replaced by '$vbulletin->db'. Also 'query' is not used anymore (although it will still work), and should be replaced by either 'query_read' or 'query_write'.

it is fixed now
