1, the input information to verify the class (mainly used to verify the user name, password, duplicate password, mailbox, can add other functions)
Copy CodeThe code is as follows:
/**
* Validator for Register.
*/
Final class Registervalidator {
Private Function __construct () {
}
/**
* Validate the given username, password, repeat_password and email.
* @param $username, $password, $repeat _password and $email to be validated

2. Make a call on the registration page
Copy CodeThe code is as follows:
$username = null;
$password = null;
$repeat _password = null;
$email = null;
$msg = "";
if (isset ($_post[' username ')) && isset ($_post[' password '])

Validate

Save
$dao = new Userdao ();

}
foreach ($errors as $e) {

}
3. Error message in code to log validation
Copy CodeThe code is as follows:
/**
* Validation error.
*/
Final class Error {

Private $message;
/**
* Create new error.
* @param mixed $source source of the error
* @param string $message error message
*/

/**
* Get source of the error.
* @return Mixed source of the error
*/
Public Function GetSource () {

}
/**
* Get error message.
* @return String Error message
*/
Public Function GetMessage () {
return $this->message;
}
}
?>
