CodeIgniter form validation valid_email not working
提问by James Jeffery
I am trying to use CodeIgniter's form validation class. I've used the "valid_email" parameter, as can be seen from the code below, but even when an invalid email address is entered it still passes the validation check. I tested with the string: testing123
我正在尝试使用 CodeIgniter 的表单验证类。我使用了“valid_email”参数，从下面的代码可以看出，但即使输入了无效的电子邮件地址，它仍然可以通过验证检查。我用字符串进行了测试：testing123
public function login()
{
$this->form_validation->set_rules('authEmail', 'trim|required|valid_email|xss_clean');
$this->form_validation->set_rules('authPassword', 'trim|required');
$email = $this->input->post('authEmail');
$password = $this->input->post('authPassword');
if($this->form_validation->run() === FALSE) {
$this->session->set_flashdata('formValidationError', validation_errors('<p class="error">', '</p>'));
redirect('/');
} else {
// Begin authentication
}
}
Anyone have any idea what I'm doing wrong or if this is a CodeIgniter issue?
任何人都知道我做错了什么，或者这是否是 CodeIgniter 问题？
To note, I am setting a flashdata session as opposed to using:
请注意，我正在设置 flashdata 会话，而不是使用：
<?php echo validation_errors(); ?>
... this is because I am doing a redirect back to the homepage (which is the login page as it's a private site).
...这是因为我正在重定向回主页（这是登录页面，因为它是一个私人站点）。

Try this:
尝试这个：
public function login()
{
$this->load->library('form_validation');
$this->form_validation->set_rules('authEmail', 'Email', 'trim|required|valid_email|xss_clean');
$this->form_validation->set_rules('authPassword', 'Password', 'trim|required');
if($this->form_validation->run() !== false){
//validation passed
$email = $this->input->post('authEmail');
$password = $this->input->post('authPassword');
// Begin authentication
}
else {
$this->session->set_flashdata('formValidationError', validation_errors('<p class="error">', '</p>'));
redirect('/');
}
}

I'm just learning to use it as well, but don't you need three parameters? This is from their form validation page:
我也是刚学用，但是你不需要三个参数吗？这是来自他们的表单验证页面：
$this->form_validation->set_rules('email', 'Email', 'required');

The field name - the exact name you've given the form field.
A "human" name for this field, which will be inserted into the error message. For example, if your field is named "user" you might give it a human name of "Username". Note: If you would like the field name to be stored in a language file, please see Translating Field Names.
The validation rules for this form field.
