Yii2 framework study notes (5) -- changing the skin for the backend

Make a distinction between the frontend and the backend, and change the AdminLTE skin for the backend.

There is a ready-made adminLTE plug-in for yii2 on the Internet, use it directly.

Add the following content to the require node in composer.json

"require": {
         ...
         "dmstr/yii2-adminlte-asset": "2.*",
         ...
    },

Run the composer update installation code.

After the installation is complete, copy the contents of the site/layouts folders under /vendor/dmstr/yii2-adminlte-asset/example-views/yiisoft/yii2-app to overwrite those under /backend/views/ folder with the same name.

Make some slight changes.

backend/views/layouts/main.php, according to the prompts inside, delete the content in the first if, as shown below.

assetManager->getPublishedUrl('@vendor/almasaeed2010/adminlte/dist');
    ?>
    beginPage() ?>
    
    
    
        
        
        
        
        head() ?>
    

    
    beginBody() ?>
    


        render(
            'header.php',
            ['directoryAsset' => $directoryAsset]
        ) ?>

        render(
            'left.php',
            ['directoryAsset' => $directoryAsset]
        )
        ?>

        render(
            'content.php',
            ['content' => $content, 'directoryAsset' => $directoryAsset]
        ) ?>

    

    endBody() ?>
    
    
    endPage() ?>

Then in backend/controllers/SiteController.php, point to the layout that needs to be used for login in aiontLogin.

public function actionLogin()
    {
        if (!\Yii::$app->user->isGuest) {
            return $this->goHome();
        }
        // add this line to use the right layout
        $this->layout = '//main-login';
        $model = new LoginForm();
        if ($model->load(Yii::$app->request->post()) && $model->login()) {
            return $this->goBack();
        } else {
            return $this->render('login', [
                'model' => $model,
            ]);
        }
    }

The finished effect is as follows.
