[Maq]

You're trying to invoke methods from the $db object but it's just declared as a global.

global $db;

 

Did you mean create an object from a database class you have?

[requinix]

$db is not an object. Probably null/undefined.

Include whatever file that defines $db.

 

 

Unless there's some OOP magic going on. Which is impossible to tell with that code snippet and total lack of explanation of anything.

i do have a class for it

but all it dose is echo about almost everything

dbh = @mysql_connect($dbhost,$dbuser,$dbpassword); if ( ! $this->dbh ) { $this->print_error("

[requinix]

Not the kind of magic I was thinking about. Maq hit the nail on the head.

[zhshero]

i don't even know what OOP magic is

[Maq]

i don't even know what OOP magic is

 

This is solved, correct?

[zhshero]

yeah but i still don't know what that is tho

 

the OOP magic

[Maq]

yeah but i still don't know what that is tho

 

the OOP magic

 

I don't think he meant anything in particular, AFAIK it doesn't mean anything, except that OOP can be a bit mysterious and confusing how it works sometimes especially if you're new.
