Yii2 - How do I AutoLoad a custom class?

Question

I have created the following custom class that I'd like to use in my Yii2 application:

@common/components/helper/CustomDateTime.php

namespace common\components\helper;
class CustomDateTime{function Now() {...}}

I want to use this class like this:

public function actionDelete($id)
{
    $account = $this->findModel($id);
    $account->archived = 1;
    $account->archived_date = CustomDateTime::Now();
    $account->save();

    return $this->redirect(['index']);
}

In my @common/config/bootstrap.php file I've created a classMap according to this http://www.yiiframework.com/doc-2.0/guide-concept-autoloading.html.

Yii::$classMap['CustomDateTime'] = '@common/components/helper/CustomDateTime.php';

But I am getting the error: Class 'app\controllers\myapp\CustomDateTime' not found

QUESTION: How do I create a classMap so that I don't have to use the use statement at the beginning of every controller to access my custom class?

Yii 1.1 used to have an option in the config file to 'import' a set of code so that a class file could be autoloaded when it was called.

SOLUTION

Many thanks to @Animir for redirecting me back to the original documentation. http://www.yiiframework.com/doc-2.0/guide-concept-autoloading.html.

I found that I can use the following in my @common/config/bootstrap.php file

Yii::$classMap['CustomDateTime'] = '@common/components/helper/CustomDateTime.php';

BUT - it only works when the the CustomDateTime.php file does NOT have a declared namespace.

//namespace common\components\helper;
class CustomDateTime{function Now() {...}}

Answer 1

Auto load in Yii 2 is pretty easy. You can use it by loading the class with config main file. like

You have created your class in components/helper/CustomDateTime.php . and now in your config/main.php in the top of the file add below code

require_once( dirname(__FILE__) . '/../components/helper/CustomDateTime.php');

Now your class is autoloaded in your project where ever you want to use it you can use like in your controller,model or view

Simply use like this

CustomDateTime-><methodName>();

Try this i have used this in my project.
