README

Use Yii 2 widgets in legacy Yii 1 applications.

Requirements

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist "neam/yii-yii2-bridge" "*"

or add

"neam/yii-yii2-bridge" : "*"

to the require section of your application's composer.json file.

Make sure you have the following in your yii 1 app's composer.json:

"extra": {
    "asset-installer-paths": {
        "npm-asset-library": "vendor/npm",
        "bower-asset-library": "vendor/bower"
    }
},

In your index.php, instead of including yii.php, do the following (which will include yii 1 and yii 2):

$approot = dirname(__FILE__) . DIRECTORY_SEPARATOR . '..';
require("$approot/vendor/neam/yii-yii2-bridge/include.php");

Make sure that your layout or view file includes:

// Necessary in order to publish the yii2 assets required for this view
Yii::$app->getView()->registerYii2Assets();

Install yii 2 widgets via composer and use them as usual.

Loads but does not run a Yii 2 app, so that it is available under Yii::$app.
Overrides the core yii 2 view component to register asset files using Yii 1 client script.
Disables the yii 2 error handler so that both error handlers are not activated at the same time.
