Error with mysqli

zbee

I have xampp 1.5.4 on a Win XP and have an application running fine. I was asked to install the same application on a Win2K, so I installed the same version of xampp and dumped all the databases and tables, but now I get an error of :

Fatal error: Call to a member function fetch_row() on a non-object in ...\imperial\compras\compra.php on line 31

Does anyone have a clue on what's happening?
I'm using mysqli to connect to certain db's.

It means exactly what the error is saying, u create an object and call for the fetch_row method witch is not a member of that object ....

Yes, I'm trying to do a fetch_row on a non-object. That's not the problem. The problem is that the same code works on my lap top. I even debugged the same line of code with a gettype($var) and on my laptop it says object, but on my desktop it says boolean. So my question is why the same code, with the same environment does not behave the same way?

The problem is caused by an earlier error that you didn't pick up on. Fix your error handling. It might be a good idea to enable error_reporting(E_ALL) then have an error handler which wraps them in exceptions. That way nothing will slip through.

Error reporting is "ON" on both my laptop and pc, but only the pc shows the error.

error_reporting is not an on/off setting, it has many different possible values. Enable E_ALL and you will hopefully see the error which caused the problem.

The "Call to a member function on a non-object" is almost certainly the result of an earlier (unreported) error, causing some function which should return an object to return (for example) FALSE.
