Form Helper - set_value()

So, oddly enough, this doesnt work actually

Edit: Maybe were using diff CI versions? But the code for set_value doesnt even look for _field_data, just looks right at $this->post

form_helper.php:

PHP Code:

<?php
if ( ! function_exists('set_value'))
{
    /**
     * Form Value
     *
     * Grabs a value from the POST array for the specified field so you can
     * re-populate an input field or textarea. If Form Validation
     * is active it retrieves the info from the validation class
     *
     * @param    string    $field        Field name
     * @param    string    $default    Default value
     * @param    bool    $html_escape    Whether to escape HTML special characters or not
     * @return    string
     */
    function set_value($field, $default = '', $html_escape = TRUE)
    {
        $CI =& get_instance();

        $value = (isset($CI->form_validation) && is_object($CI->form_validation) && $CI->form_validation->has_rule($field))
            ? $CI->form_validation->set_value($field, $default)
            : $CI->input->post($field, FALSE); // RIGHT HERE

        isset($value) OR $value = $default;
        return ($html_escape) ? html_escape($value) : $value;
    }
}
