[quote author="PermanaJ" date="1245342070"]whoops ... I handle which one from $upload_error or $photo exist .. if $upload_error, then show error and stop processing form .. I just need to continue processing form even there are $upload_error[/quote]

your right but your code suggests that it should not pass the first if statement

have you tried

Code:

if ($_FILES['photo']['name']!="") {
    if( !$this->upload->do_upload('photo')){
        $upload_error = $this->upload->display_errors();
    }else{
        $photo = $this->upload->data();
    }
};

that way you can keep the display errors in if the upload fails when there is a file to upload.
