Keeps current URL in session for controller actions so we can return to it if needed.

This is Yii2 port of set-return-url-filter extension.

In "composer.json" your project, add the following lines:

"require": {
    ...
    "dlds/yii2-return-url": "*"
},

Then update your project:

php composer.phar update --prefer-dist

In your controller add ReturnUrl filter to behaviors:

public function behaviors()
{
    return [
        'returnUrl' => [
            'class' => 'dlds\returnUrl\ReturnUrl',
        ],
    ];
}

For access to previously visited url:

Yii::$app->user->getReturnUrl();
