Hi all
i am newcomer for Yii2.
When i learn Yii2 basic login demo,i was confused about：
in \yii2\basic\models\User.php：
public function validatePassword($password)
{
return $this->password === $password;
}
well，when and where（$this->password）was filled out？
thx
：）
when login form is submitted
sitecontroller loginaction u will find below code.
if ($model->load(Yii::$app->request->post()) && $model->login()) {
so it will goes to loginform model.
in models/loginform
in rules: ['password', 'validatePassword'],
public function validatePassword($attribute, $params)
{
if (!$this->hasErrors()) {
$user = $this->getUser();
if (!$user || !$user->validatePassword($this->password)){
$this->addError($attribute, 'Incorrect username or password.');
}
}
}
in models/user
public function validatePassword($password)
{
return $this->password === $password;//here $this->password is stored db password and $password is pass from loginform.
}
here compare string with data types.
In the basic template, the usernames and passwords are stored in the $users array in app\models\User, when the user attempts to log in, the User object is populated from the $users array and that is where the password comes from.
thx,your code flow is so clear。
but as mentioned：
“return $this->password === $password;//here $this->password is stored db password and $password is pass from loginform.”，
password is from loginform，my question is：
which step $this->password is filled？
which method？
thx again。
thx。
as mentioned：
“the User object is populated from the $users array and that is where the password comes from.”
can U explain some more details？
see this code：（in basic\models\User.php）
class User extends \yii\base\Object implements \yii\web\IdentityInterface
{
public $id;
public $username;
public $password;
public $authKey;
public $accessToken;
private static $users = [
'100' => [
'id' => '100',
'username' => 'admin',
'password' => 'admin',
'authKey' => 'test100key',
'accessToken' => '100-token',
],
'101' => [
'id' => '101',
'username' => 'demo',
'password' => 'demo',
'authKey' => 'test101key',
'accessToken' => '101-token',
],
];
。。。。。。
////
there are two members in $users（ admin and demo ）
thx again。
It is in the function
public static function findByUsername($username)
{
foreach (self::$users as $user) {
if (strcasecmp($user['username'], $username) === 0) {
return new static($user);
}
}
return null;
}
This is called when the user attempts to login. If their username exists in the $users array, a new User is returned which is populated by the contents of the array. The syntax new static($user) means create a new type of the current class using the data in the given array to populate the fields.
