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

I've found that where:

1. there's more than one CI view-partials which make up the page and their controller methods perform validation
2. one of the validations failed and produced an error since the last page-refresh, say with an incorrectly formatted or typed input field value

it isn't enough to clear only the validation-rules array, you need to clear the validation-error array too.

To this end, I've added a method to system/libraries/Form_Validation.php, as follows:

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

Returning $this is important if you want to chain your form-validation methods.

Answer 2

In newer version 3.X, to clear set_value , $_POST=array() and $this->_field_data = array(); in MY_Form_validation.php library. try
