How to check that my observer file was called from admin or frontend in magento 2?

Question

I am using sales_order_save_after in Global scope. I am creating orders from admin programmatically( Order, Invoice and Shipment). Each and every time this event is calling.

I want to check and update the order increment id with the prefix value only from the front end order.

How can i check the observer calling from front end scope?

Answer 1

Inject the Magento\Framework\App\State class object in your observer's __construct method and store the object into the observer class property, so that you can access getAreaCode().

For example:

protected $state;

public function __construct (
    \Magento\Framework\App\State $state
) {
    $this->state = $state;
}

public function getArea()
{
    return $this->state->getAreaCode();
}
