which is working fine . But how to handle if same state_name exist in different countrystate. My database table is like this

`id` `country_id`  `state`   `status`
 1     1             abc         0
 2     2             abc         0

Answer 1

您可以为此创建复合唯一密钥。

$crud->unique_fields('country_id', 'state');
