Let's see what exactly are the events in Yii!

It's well known that there are Lazy Loading approach and Eager Loading approach in the relational query. But it's very important to know how the Eager Loading approach works in Yii 2. It has changed drastically from that of Yii 1.1, and there are common misunderstandings about it in the community.

I have an API. It's built with a RESTful extension over Active Record, and some endpoints provide PUT methods to upload files. By a REST design we create an entity with POST /video first, and then upload a video file with PUT /video/{id}/data.

I've seen many tickets regarding how to show friendly delete confirmation using CGridView's CButtonColumn in ajax request. If you are using relational database, after producing CRUD functionality when you try to delete a record in ajax mode which has child record it can't be deleted and you can see the ajax loader forever. By this way you can't show the users if a record has been successfully dele...

The CRUD generator of Gii has done a wonderful job for you, and you already have a list of items in the "index" page and a detailed view of a specified item in the "view" page.

If we want to set meta tags on a per page (controller-action) basis, we may use the clientScript application component.

An example of customizing the Yii GridView is mentioned here. You can easily override Bootstrap or other styling defaults by changing the GridView default options.

I discovered Twitter Bootstrap almost two years ago. After trying it out for a while I fell in love with it. It didn't take long before I realized that it would be great to write an extension that allowed developers to start using Bootstrap in their Yii projects. One night I sat down and started writing what later became my now popular [bootstrap extension](http://ww...

Hey Everyone, In this post I Just shared my Experience what most of interviewer ask in YII2 Interview.

Suppose to have two models: Users and Emails. You do not want to store email in a Users model. And User can have 0 or many emails. This is the form generated to create a new user (just username).

Add these lines in /config/main.php

'components'=>array(
.........
		'db'=>array(
			'connectionString' => 'mysql:host=localhost;dbname=database1',
			'emulatePrepare' => true,
			'username' => 'root',
			'password' => 'itsasecret',
			'charset' => 'utf8',
		),
		'db2'=>array(
		    'class' => 'CDbConnection',
			'connectionString' => 'mysql:host=localhost;dbname=databa...

This is what I did. Its the EASIEST solution that I know of. I just reused the advanced search done in CGridView.

In this wiki I will show how could use a TbActiveForm for changing the old password with help of old, new and repeat password features.

Gii provides us normally with the following code on the 'actionCreate':

public function actionCreate()
{
   $model=new ModelName;

This is a shortcut for adding a text search for multiple values i.e.

This wiki shall be considered deprecated since the Yii installer for composer has been discontinued.

Lets say we have such a CGridView widget showing a list of users for administrator. Users have status „active“ or „disabled“. Grid widget puts class „odd“ or „even“ to rows and we want to preserve this. So we want to add a class „disabled“ to rows with disabled users.

Implementation

<?php
$this->widget('zii.widgets.grid.CGridView', array(
	'id'=>'user-grid',
	'dat...

will generate twitter bootstrap styled breadcrumb code:

I normally create a files folder and I allocate it within my www one, that is where I keep my css, js, images files. So, even though you can place it where ever you wish and for the sake of the example, I will use the files folder name.

There are a couple of ways to achieve this, but the first is preferred.
