if function equal() could return a field name

[harpreetsb]

hey,
if you could, provide an option to help return the field name or an option to pass field name to be returned
Sample code

public function equal($field_1, $field_2, $err_msg = '', $returnField=2){
 .......
}

here returnField can either be the name of field to be returned or numeric position of fields as passed. Default can be 2 will return $field_2.

thank you

Oh I made a change

/**
     * Check that the two fields are equal.
     *
     * @access public
     * @param mixed $field_1
     * @param mixed $field_2
     * @param string $err_msg (default: '')
     * @return void
     */
    public function equal($field_1, $field_2, $err_msg = '', $returnField=null) {
        if ($this->is_valid()) {
            if (strcmp($this->data[$field_1], $this->data[$field_2]) != 0) {
                $this->_error($err_msg, $returnField);
            }
        }
        return $this;
    }

Usage

$this->validation->equal('password', 'repassword', lang('password_confirm_error'), 'repassword');
