Hello everybody. I could not post an article because I didn't have new knowledge to share. Ok, this day I will share about "Change password with validation and repeat password on Yii2".
I still using the yii2basic applicaton. If you don't have it, please refer this for develop it.
If you have yii2basic application, then you must create PasswordForm.php file and save it in the models directory. Please add the code bellow.
If you have yii2basic application, then you must create PasswordForm.php file and save it in the models directory. Please add the code bellow.
<?php
namespace app\models;
use Yii;
use yii\base\Model;
use app\models\Login;
class PasswordForm extends Model{
public $oldpass;
public $newpass;
public $repeatnewpass;
public function rules(){
return [
[['oldpass','newpass','repeatnewpass'],'required'],
['oldpass','findPasswords'],
['repeatnewpass','compare','compareAttribute'=>'newpass'],
];
}
public function findPasswords($attribute, $params){
$user = Login::find()->where([
'username'=>Yii::$app->user->identity->username
])->one();
$password = $user->password;
if($password!=$this->oldpass)
$this->addError($attribute,'Old password is incorrect');
}
public function attributeLabels(){
return [
'oldpass'=>'Old Password',
'newpass'=>'New Password',
'repeatnewpass'=>'Repeat New Password',
];
}
}
The above code is model class for implement to change password form. Let's create changepassword.php file in views/site directory.
It use to make changepassword view. It show change password form to end users. Please add the code bellow.
<?phpAnd then you must change SiteController.php file in controllers directory. Please following this code and add to your SiteController.php
use yii\helpers\Html;
use yii\bootstrap\ActiveForm;
$this->title = 'Change Password';
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="site-changepassword">
<h1><?= Html::encode($this->title) ?></h1>
<p>Please fill out the following fields to change password :</p>
<?php $form = ActiveForm::begin([
'id'=>'changepassword-form',
'options'=>['class'=>'form-horizontal'],
'fieldConfig'=>[
'template'=>"{label}\n<div class=\"col-lg-3\">
{input}</div>\n<div class=\"col-lg-5\">
{error}</div>",
'labelOptions'=>['class'=>'col-lg-2 control-label'],
],
]); ?>
<?= $form->field($model,'oldpass',['inputOptions'=>[
'placeholder'=>'Old Password'
]])->passwordInput() ?>
<?= $form->field($model,'newpass',['inputOptions'=>[
'placeholder'=>'New Password'
]])->passwordInput() ?>
<?= $form->field($model,'repeatnewpass',['inputOptions'=>[
'placeholder'=>'Repeat New Password'
]])->passwordInput() ?>
<div class="form-group">
<div class="col-lg-offset-2 col-lg-11">
<?= Html::submitButton('Change password',[
'class'=>'btn btn-primary'
]) ?>
</div>
</div>
<?php ActiveForm::end(); ?>
</div>
use app\models\PasswordForm;Ok, it's time to trial this application. You must login with already user and access this url in your browser "http://localhost/tutorial/web/index.php?r=site%2Fchangepassword"
use app\models\Login;
class SiteController extends Controller{
public function behaviors(){
return [
'access' => [
'class' => AccessControl::className(),
'only' => ['logout'],
'rules' => [
[
'actions' => ['logout','changepassword'],
'allow' => true,
'roles' => ['@'],
],
],
],
'verbs' => [
'class' => VerbFilter::className(),
'actions' => [
'logout' => ['post'],
],
],
];
}
//other code default
public function actionChangepassword(){
$model = new PasswordForm;
$modeluser = Login::find()->where([
'username'=>Yii::$app->user->identity->username
])->one();
if($model->load(Yii::$app->request->post())){
if($model->validate()){
try{
$modeluser->password = $_POST['PasswordForm']['newpass'];
if($modeluser->save()){
Yii::$app->getSession()->setFlash(
'success','Password changed'
);
return $this->redirect(['index']);
}else{
Yii::$app->getSession()->setFlash(
'error','Password not changed'
);
return $this->redirect(['index']);
}
}catch(Exception $e){
Yii::$app->getSession()->setFlash(
'error',"{$e->getMessage()}"
);
return $this->render('changepassword',[
'model'=>$model
]);
}
}else{
return $this->render('changepassword',[
'model'=>$model
]);
}
}else{
return $this->render('changepassword',[
'model'=>$model
]);
}
}
}
