<?php namespace app\controllers; use yii; use yii\filters\accesscontrol; use yii\web\controller; use yii\filters\verbfilter; use app\models\loginform; class sitecontroller extends controller { public $layout = "login"; public function behaviors() { return [ 'access' => [ 'class' => accesscontrol::classname(), 'only' => ['logout'], 'rules' => [ [ 'actions' => ['logout'], 'allow' => true, 'roles' => ['@'], ], ], ], 'verbs' => [ 'class' => verbfilter::classname(), 'actions' => [ 'logout' => ['post'], ], ], ]; } public function actions() { return [ 'error' => [ 'class' => 'yii\web\erroraction', ], 'captcha' => [ 'class' => 'yii\captcha\captchaaction', 'fixedverifycode' => yii_env_test ? 'testme' : null, ], ]; } public function actionindex() { $model = new loginform(); if ($model->load(yii::$app->request->post()) && $model->login()): return $this->redirect(["landing/index"]); else: return $this->render('index', [ 'model' => $model, ]); endif; } public function actionlogout() { yii::$app->user->logout(); return $this->gohome(); } } first time happend me.
i pretty sure it's rendering in layout files. show code of views/layouts/main.php , if have sub-templates well. e.g. if have there multiple parts of following code result mentioned, e.g. multiple echo of $content.
<?php $this->beginbody() ?> <?= $content ?> <?php $this->endbody() ?> another possibility multiple call of echo $this->render('yourview',...) in controller code. should return , not echo render calls e.g. return $this->render('yourview',...) instead. couldn't rendered multiple times.
