CodeIgniter Validation Rules for Email and Password
提问by Mohamed Ebrahim
I was used to coding application with CodeIgniter and I'm a total newbie. I just started to learn CodeIgniter 3.0, and and reached to validation rules.
我习惯于使用 CodeIgniter 编写应用程序，我完全是个新手。我刚开始学习 CodeIgniter 3.0，并达到了验证规则。
I notice that xss_cleanis now gone from the validation class, so what rules should I use in the validation of email and password? Using just trim, valid_email, and required is enough for security?
我注意到xss_clean现在从验证类中消失了，那么我应该在验证电子邮件和密码时使用什么规则？只需使用trim，valid_email以及所需的安全性是否足够？
Sorry if that question has been asked, but I searched around and I see old topics where people is using xss_clean.
抱歉，如果有人问过这个问题，但我四处搜索，看到人们使用xss_clean.

Include Email Helper:
包括电子邮件助手：
$this->load->helper('email');
$this->load->helper('email');
For Email:
对于电子邮件：
$this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email|xss_clean');
Or you can also use PHP Filter for email validation as
或者您也可以使用 PHP 过滤器进行电子邮件验证
filter_var($email, FILTER_VALIDATE_EMAIL);
filter_var($email, FILTER_VALIDATE_EMAIL);
For Password Expression
对于密码表达式
public function chk_password_expression($str)
{
if (1 !== preg_match("/^.*(?=.{6,})(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z]).*$/", $str))
{
$this->form_validation->set_message('chk_password_expression', '%s must be at least 6 characters and must contain at least one lower case letter, one upper case letter and one digit');
return FALSE;
}
else
{
return TRUE;
}
}
To call the function you should use:
要调用该函数，您应该使用：
$this->form_validation->set_rules( 'password', 'Password', 'trim|required|min_length[6]|max_length[15]|callback_chk_password_expression');
Note: chk_password_expression should be in same class controller or in parent class. Email helper should be included as $this->load->helper('email');
注意：chk_password_expression 应该在同一个类控制器或父类中。电子邮件助手应包含为 $this->load->helper('email');
