Codeigniter Form Validation - how to unset form values after success?

Question

I realise this request goes against the example provided in the CI documentation (which advises a separate \'success\' page view), but I would like to reutilise a given form

Answer 1

Hope this would be helpful. Finally I understand the whole concept of the extending the library. All you need to do is
Step 1: In this directory "application/libraries/" create a file named "MY_Form_validation.php" with the following php code

_field_data);    
    }
}

Step 2: Then use the function "unset_field_data()" in you controller. for example below:

    if ($this->form_validation->run())
    {
        $this->item_model->add_item($this->input->post('name'));
        $success = true;

        $this->form_validation->unset_field_data();
    }
