mình chạy đến dòng 85 thì code là như thế này:

function db_num_rows($result) {
return mysql_num_rows($result);
}
 

cho mình hỏi lỗi nằm ở function db_num_rows hay tại vấn đề nằm ở config php trên server
mong mọi người chỉ mình cách giải quyết, xin đa tạ

đây là cấu hình field productid trong db của mình

Field | Type | Collation |Attributes |Null |Default | Extra
productid | int(11) | | | No |auto_increment |
