我想检查值是否不是整数和浮点数,我已经编写了表单验证,如下所示,

$this->form_validation->set_rules('charge_hour', 'Per hour', 'xss_clean|callback_money_type');
$this->form_validation->set_rules('charge_day', 'Per day', 'xss_clean|callback_money_type');
$this->form_validation->set_rules('charge_weekly', 'Per week', 'xss_clean|callback_money_type');
$this->form_validation->set_rules('charge_monthly', 'Per month', 'xss_clean|callback_money_type');

所有文本文件的通用回调函数是money_type()
    public function money_type($charge)
        {
            if (is_float($charge) == false && is_int($charge) == false && $charge >= 0)
            {
                $this->form_validation->set_message('{WHAT TO ENTER HERE}', 'Enter valid charges for space.');
                return FALSE;
            }
        else
        {
            return TRUE;
        }
    }

在验证过程中,我如何找出{此处输入什么}?字段名是charge-hour、charge-day、charge-weekly和charge-monthly中的任意一个?这样表单验证将为每个字段显示不同的错误消息。
谢谢。

最佳答案

$this->form_validation->set_message('money_type','%s my message');
