When we need to to call another controller function,we can simply use the below code Yii::$app->runAction('publish/commit',[                     'r' => 'ws' ]); write it in Controller A index method and you can get the value of $r  in Controller Publish commit method.    

  Its called 'scenarios': http://www.yiiframework.com/doc-2.0/guide-structure-models.html#scenarios in model: public function rules() { return [ ['title', 'required', 'on' => 'create'] ]; } in controller: public function actionCreate() { $model = new Item(); $model->scenario = 'create'; ... } You'd better define scenario as a constant though.   source : http://stackoverflow.com/questions/29449019/yii2-validate-only-create-action

Answer In a layout you can access the current controller via $this->context, and so the current action id by $this->context->action->id For reference http://stackoverflow.com/questions/28769719/yii2-get-current-action-id-in-main-php

Pagination represents information relevant to pagination of data items. When data needs to be rendered in multiple pages, Pagination can be used to represent information such as total item count, page size, current page, etc. These information can be passed to pagers to render pagination buttons or links. The following example shows how to create a pagination object and feed it to a pager. Controller action: public function actionSearch($q = '') {         $this->layout = 'site_main';         $q = trim($q);         $sql = "SELECT * FROM (select p.product_id as 'sid',p.name_en,p.name_ar,p.description_en,description_ar,p.imag....

leftJoin() $query = new Query; $query    ->select(['tbl_user.username AS name', 'tbl_category.type as Category'])           ->from('tbl_user')         ->leftJoin('tbl_category', 'tbl_category.createdby = tbl_user.userid')         ->limit(2);         $command = $query->createCommand(); $data = $command->queryAll();

innerJoinWith() $model = User::find()     ->innerJoinWith('comments', false)     ->all(); // equivalent to the above $model = User::find()     ->joinWith('comments', false, 'INNER JOIN')     ->all(); SYNTAX: $query = new Query; $query    ->select(['SELECT COLUMNS'])           ->from('TABLE_NAME_1')         ->join(    'JOIN_TYPE',                 'TABLE_NAME_2',                 'TABLE_NAME_2.COLUMN =TABLE....

joinWith() Sample 1: $model = User::find()     ->joinWith('comments')     ->all(); Sample 2: $model = User::find()     ->joinWith('comments')     ->orderBy('tbl_comments_id.id, tbl_user.id')     ->all();

Relation Model $model = User::find()         ->with('comments')         ->all();     foreach ($model as $user) {         // get data from relation model         $comments = $user->comments;         ......         foreach($comments as $comment){             ........         }     }

<?php use yiiwidgetsPjax; ?> Add above line in the beginning of your view. <?php Pjax::begin(); ?> <?= GridView::widget([ 'dataProvider' => $dataProvider, 'filterModel' => $searchModel, 'columns' => [ ['class' => 'yiigridSerialColumn'], 'id', 'branch:ntext', 'version:ntext', 'release_date:ntext', [ 'class' => 'yiigridActionColumn', 'template' => '{view}', ], ], ]); ?> <?php Pjax::end(); ?>  

First, let's enable Yii2's pretty URLs with mod_rewrite. On the Yii home page, if you click on the About menu option, the URL will be something like http://localhost/hello/web/index.php?r=site%2Fabout. We'd like to change that to http://localhost/hello/web/site/about. The config subdirectory includes environment configurations for your web and console applications as well as the future database settings. Edit /config/web.php to add urlManagement to the current web application. Add the following urlManager section within the components array: 1 2 3 4 5 6 7 8 &#....
