Module development and code questions

I have a custom module that creates a block. This block is a chat that interacts with an external service through an API.

When the user sends a message through the chat, jQuery takes the message and sends it using $.ajax() to submit.php which then does all the handling to get the response from the API and returns in back to jQuery to be displayed to the user.

Now all of this is in theory, since I haven't been able to find a way to get the correct path to that submit.php file.

I have a custom entity and I want to show entity title using two concatenated fields.

I have implemented the label method within the definition of my custom entity class:

public function label() {
$obra = $this->get('idobra')->entity;
$ordem_servico_label = format_string('@obra-@sequencial', [
'@obra' => $obra->label(),
'@sequencial' => $this->get('sequencial_obra')->value
]
);
return $ordem_servico_label;
}

Hi,

Now I use: 

$order = Order::load(1);

foreach ($order->getItems() as $key => $order_item) {
