• Get component from https://github.com/kitavrus/yii2-tcpdf

Automatic installation is NOT recommended (see NOTES below), but these are the steps:

1. Run the following command:

  $ composer require cinghie/yii2-tcpdf "dev-master" 

2. Add reference in [app]/composer.json file, in require section:

"require": {
        ...
        "cinghie/yii2-tcpdf": "dev-master"
    },

NOTE: This installation method tends to remove the [app]/vendor/cinghie/yii2-tcpdf and fails to update correctly, leaving a non-working installation. Follow the manual installation if this happens.

Manual Installation is the recommended installation method:

1. Remove the “require” reference (“cinghie/yii2-tcpdf”: “dev-master”) in the [app]/composer.json file.

2. Add reference in your configuration [app]/config/web.php (or config.php) file, in component section:

  'component' => [ 
      ...
      // Yii2 TCPDF
      'tcpdf' => [
        'class' => 'cinghie\tcpdf\TCPDF',
      ],
      ...
]

3. Add reference in [app]/vendor/yiisoft/extensions.php the following:

return array (
  ...
  'cinghie/yii2-tcpdf' => 
  array (
    'name' => 'cinghie/yii2-tcpdf',
    //'name' => 'tcpdf',
    'version' => '1.0.0',
    //'bootstrap' => '\cinghie\tcpdf\MyBootstrap',
    'alias' => 
    array (
      '@cinghie/tcpdf' => $vendorDir . '/cinghie/yii2-tcpdf',
    ),
  ),
  ...
);  

4. Create controller action. Eg:

use yii\web\Response;
...
class SiteController extends Controller
{
    public function actionPdfReport()
    {
        Yii::$app->response->format = Response::FORMAT_RAW;  // Raw for PDF output
        return $this->render('pdf-report'); 
    }
}

5. Create view. Eg: [app]/views/site/pdf-report.php
