Question

我对这个问题感到困惑。请有人教我如何做对。

这是我在控制器中的验证规则和验证字段：

function _set_fields(){
    $fields['id'] = 'id';
    $fields['tanggal'] = 'tanggal';
    $fields['kilometer'] = 'kilometer';
    $fields['merek_oli'] = 'merek_oli';
    $fields['harga_oli'] = 'harga_oli';

    //$this->form_validation->set_fields($fields);
}

// validation rules
function _set_rules(){
    //$rules['tanggal'] = 'trim|required|callback_valid_date';
    //$rules['kilometer'] = 'trim|required';
    //$rules['merek_oli'] = 'trim|required';
    //$rules['harga_oli'] = 'trim|required';

    //$this->form_validation->set_rules($rules);
    $this->form_validation->set_rules('tanggal', 'Tanggal', 'trim|required|callback_valid_date');
    $this->form_validation->set_rules('kilometer', 'Kilometer', 'trim|required');
    $this->form_validation->set_rules('merekoli', 'Merek Oli', 'trim|required');
    $this->form_validation->set_rules('hargaoli', 'Harga Oli', 'trim|required');

    $this->form_validation->set_message('required', '* required');
    $this->form_validation->set_message('isset', '* required');
    $this->form_validation->set_error_delimiters('<p class="error">', '</p>');
}

这是我的观点：

            </tr>
            <tr>

                <?php echo $this->form_validation->merekoli_error; ?></td>
            </tr>
            <tr>
                <td valign="top">Harga Oli<span style="color:red;">*</span></td>
                <td><input type="text" name="hargaoli" class="text" value="<?php echo $this->form_validation->harga_oli; ?>"/>

            <tr>
                <td>&nbsp;</td>
                <td><input type="submit" value="Save"/></td>
            </tr>
        </table>
        </div>
        </form>
        <br />
        <?php echo $link_back; ?>
    </div>
</body>
</html>

这是我的表单验证：

类MY_Form_validation扩展了CI_Form_validation {

function MY_Form_validation($config = array())
{
    parent::CI_Form_validation($config);
}

// date_validation callback
function valid_date($str)
{
    if(!ereg("^(0[1-9]|1[0-9]|2[0-9]|3[01])-(0[1-9]|1[012])-([0-9]{4})$", $str))
    {
        $this->form_validation->set_message('valid_date', 'date format is not valid. dd-mm-yyyy');
        return false;
    }
    else
    {
        return true;
    }
}

}

消息：未定义属性：CI_Form_validation :: $ kilometer_error
