Unset rule in Form Validation

I need to unset rules and result in Form Validation helper.

This will clear the entire form validation data, including rules, values, errors, etc.

Create a file called MY_form_validation.php in your application/libraries folder. In that file, put the following code:

PHP Code:

class MY_Form_validation extends CI_Form_validation {

  public function __construct()
  {
    parent::__construct();
  }

  public function clear_field_data()
  {
    $this->_field_data = array();
    return;
  }
} 


When you want to clear the form validation data, just invoke the method, like this:

PHP Code:

$this->form_validation->clear_field_data(); 


That is useful when you want to process data and then show the same form again -- but blank -- to receive new data, like when you're adding one customer record after another.
