Console Commands

Plugins and modules can add additional console commands to Craft, which will be available via the craft executable in the terminal.

Console commands are implemented very similarly to controllers, except that they should live within a console/controllers/ folder within your plugin or module’s base source folder, and they should extend

For the most part, writing console commands for Craft is identical to writing console commands for Yii, so be sure to read the Yii documentation as a starting point.

#Module Setup

If you are adding console commands to a custom module, make sure that your module class defines its root controller namespace for console requests:

namespace bar;

use Craft;

class Module extends \yii\base\Module
{
    public function init()
    {
        // Define a custom alias named after the namespace
        Craft::setAlias('@bar', __DIR__);

        // Set the controllerNamespace based on whether this is a console or web request
        if (Craft::$app->getRequest()->getIsConsoleRequest()) {
            $this->controllerNamespace = 'bar\\console\\controllers';
        } else {
            $this->controllerNamespace = 'bar\\controllers';
        }

        parent::init();

        // Custom initialization code goes here...
    }
}

You’ll also need to make sure your module is getting bootstrapped from config/app.php (or config/app.console.php).

return [
    'bootstrap' => ['bar'],
    'modules' => [
        'bar' => bar\Module::class,
    ],
];

#Registering Custom Console Commands

You can register custom console commands on Craft’s own controllers, or plugin-supplied controllers, so long as they extend craft3:craft\console\Controller. For example, plugins that supply custom element types can add their own actions to the resave controller.

To do that, use the craft3:craft\console\Controller::EVENT_DEFINE_ACTIONS event.

use craft\events\DefineConsoleActionsEvent;
use craft\console\Controller;
use craft\console\controllers\ResaveController;
use yii\base\Event;

Event::on(ResaveController::class,
    Controller::EVENT_DEFINE_ACTIONS,
    function(DefineConsoleActionsEvent $event) {
        $event->actions['products'] = [
            'options' => ['type'],
            'helpSummary' => 'Re-saves products.',
            'action' => function($params): int {
                // @var ResaveController $controller
                $controller = Craft::$app->controller;
                $query = Product::find();
                if ($controller->type) {
                    $query->type(explode(',', $controller->type));
                }
                return $controller->saveElements($query);
            }
        ];
    }
);
