CodeIgniter $ this-> form_validation-> set_message

Question

我做了一个电子邮件验证.

$this->form_validation->set_rules('email', 'Email Address', 'trim|required|valid_email|callback_email_check');

function email_check($str)
{
    if (stristr($str,'@uni-email-1.com') !== false) return true;
    if (stristr($str,'@uni-email-2.com') !== false) return true;
    if (stristr($str,'@uni-email-3.com') !== false) return true;
    $this->form_validation->set_message('email', 'Please provide an acceptable email address.');
    return FALSE;
}

提交表单后,它显示"无法访问与您的字段名称对应的错误消息".我的代码有问题吗？

Answer 1

它应该是

$this->form_validation->set_message('email_check', 'Please provide an acceptable email address.');

Answer 2

去文档参考HERE

要设置您自己的自定义消息，您可以使用以下功能：

$this->form_validation->set_message('rule', 'Error Message');

但是你有没有正确命名的规则在你的代码应该是email_check代替email

$this->form_validation->set_message('email_check', 'Please provide an acceptable email address.');
