can somebody explain why
$this->param = $this->SYSTEM->db->answer + $this->param;
is causing the error
no. because:
a, you don't mention the version of php you use
b, we don't have knowledge of you codebase (posting code listings for
a complete class really isn't going to help much)
have you tried to debug the problem? using print_r() or var_dump()?
e.g.: ...
Fatal error: Unsupported operand types
in /var/www/current/mjguest/modules/settings.php on line 52
context is
function settings(&$SYSTEM)
{
$this->SYSTEM = &$SYSTEM;
$this->SYSTEM->db->ask(1, 'settings_load');
$this->SYSTEM->db->get_row();
echo '<pre>';
var_dump($this->SYSTEM->db->answer, $this->param)
echo '</pre>';
$this->param = $this->SYSTEM->db->answer + $this->param;
}
