You need more error handling on the various database calls, then. Quick/dirty method is to simply do

 $whatever = mysqli_somefunction(...) or die("MySQL error: ". mysqli_error());

All of the functions return boolean FALSE if an error occured, or an appropriate mysqli object with the results. Without the error checking, you'd be doing:

 $result = $mysqli->query("blah blah will cause a syntax error");
 $data = $result->fetchRow();  // $result is "FALSE", not a mysqli_object, hence the "call to member on non-object"
