How to instantiate a custom block in Magento 2

- Magento 2

Magento 2 Development

Unfortunately, the process is not as easy as in Magento 1 ($crumbs = Mage::app()->getLayout->getBlock(‘breadcrumbs’);). In Magento 2, it depends on where you are going to instantiate it from. To create an instance from another block, use the following code:

from a controller:

from a model and a helper:

Please note that in a case of the model you have to create _blockFactory (a protected member), and inject a \Magento\Framework\View\Element\BlockFactory instance in the constructor, assigning it to the member var. For instance:

How to instantiate a model in Magento 2

- Magento 2

Magento 2 Development

Since Magento strictly discourages the use of ObjectManager, there are service classes for abstracting it for all scenarios. Thus, you should use factory for all models (non-injectables):

How to create a Magento 2 playground test file with an initialised Magento 2 application

- Magento 2

Magento 2 Development

Create a test.php file in the root of your Magento 2 instance.

In the same place, create a TestApp.php file with the following content:

Call your test.php file in a browser to execute everything from TestApp::launch().

The createApplication method from the bootstrap class creates an application class instance and expects the implementation of \Magento\Framework\AppInterface that contains 2 methods.

You create your own class in TestApp to implement the interface. Since the catchException method always returns false, your app don’t handle exceptions. If something goes wrong, print it on a screen.

The implemented launch method is called by \Magento\Framework\App\Bootstrap::run. The run method behaves almost the same in spite of what the application passed as a parameter.

$response = $application->launch(); is the only thing that depends on the app. It means that calling \Magento\Framework\App\Bootstrap::run inits the Magento env and calls the launch method from your app. Therefore, put all the dirty code inside this method.

Then, \Magento\Framework\App\Bootstrap::run calls $response->sendResponse();, where under $response we mean everything what the launch method returns. Thus, return $this->_response; is required, as it returns an empty response.

The above app class extends \Magento\Framework\App\Http so you get request, response, and other parameters, but you can omit this by making your class extend nothing. Continue Reading
