Simply write PHP validation classes to teach you how to write PHP programs (with multiple validation rules) _php Tutorial

Many people in the development of the site is often only through simple JS verification, when you accidentally in the JS more than a comma or the number of points, IE6 can not recognize the direct skip verification. In fact, the safest way to do this is to verify the data entered by the user on the server. I wrote a simple PHP validation class, including a variety of validation rules for everyone to learn the reference. Original link

Of course, if you feel that validation doesn't meet your needs, you can also create subclasses to extend your approach

[PHP]
/**
* User Database Asynchronous authentication
* Author Haining Zhang
* Date 2013-05-23
*/
Class Ajaxvalidate extends validate{
Private $role _name = Array (
Verify that the user name exists
' Is_username ',

Verify that the nickname is present
' Is_nickname ',
);

Private $db;

Public Function __construct () {
$this->db = &load_system ("Database");
$this->set_role_name ($this->role_name);
}

Determines whether the user name can be registered (prevents duplicate user names)
Public Function Is_username ($username) {
$_username = $this->db->filter (' s ', $username);
$sql = "SELECT id from user where username =". $_username;
if ($this->db->num_rows ($sql)) {
return false;
}else{
return true;
}
}

Determine if a nickname is available (prevent nickname duplication)
Public Function Is_nickname ($nickname) {
$_nickname = $this->db->filter (' s ', $nickname);
$sql = "SELECT id from user where nickname =". $_nickname;
if ($this->db->num_rows ($sql)) {
return false;
}else{
return true;
}
}
}
