Question

在HMVC CI中使用回调函数时收到表单验证错误...我对问题没什么了解...我的验证代码是-

$this->form_validation->set_rules('username', 'Email', 'trim|required|valid_email|callback_IsEmail_exist');

function IsEmail_exist() {
        $existing_email = $this->db->where("email", $this->input->post('username'))->get('tbl_user')->num_rows();//p($existing_email);echo $this->db->last_query();die;
        if ($existing_email != "0") {
            $this->form_validation->set_message('email', 'Email ID already Exist.');
            return false;
        }
    }

以下代码位于Custom_Form_validation.php中：


/* custom function by Pikachu */

class Custom_Form_validation extends CI_Form_validation {

    public $CI;

    function run($module = '', $group = '') {
        (is_object($module)) AND $this->CI = &$module;
        return parent::run($group);
    }

}

以及在我的控制器中：

function __construct() {
        parent::__construct();
        $this->load->library('form_validation');
        $this->load->library(array('Custom_Form_validation'));
        $this->form_validation->CI =& $this;
        $this->load->model('custom_model', 'custom');
    }

在视图表单中仍然收到“需要电子邮件”错误消息。请帮助解决此问题。

您好@pikachu而不是这样做-

Dashboard widget on Mac OS X export is no longer supported in Unity 5.4+.

将管道元素分成单独的参数，例如-

$this->form_validation->set_rules('username', 'Email', 'trim|required|valid_email|callback_IsEmail_exist');

这可能会对您有所帮助。
