Signature card
displayAdminOrderSide hook
We use this hook to display a scanned customer signature.
Let’s create custom repository OrderSignatureRepository class inside demovieworderhooks/src/Repository folder.
Symfony Repository classes (https://symfony.com/doc/4.4/doctrine/repository.html) help to interact with the database by providing frequently used functions
like findOneBy to get the data (for example filtered data by a certain criteria - orderId
field from OrderSignature entity).

order_signature
table created and the repository starts with the same wording OrderSignatureRepository.Let’s create OrderSignature entity class inside demovieworderhooks/src/Entity folder and use
Doctrine Object Relational Mapping (ORM) annotations.
Also we map this entity with the repository with
repositoryClass="PrestaShop\Module\DemoViewOrderHooks\Repository\OrderSignatureRepository".
This mapping allows to use functions of SignatureRepository instead of only the EntityRepository.

Let’s put our signature picture, john_doe.png inside demovieworderhooks/signatures/ folder.
Signature
Let’s create Order Repository and data structures for interacting with Orders data.
Data Transfer Object (https://en.wikipedia.org/wiki/Data_transfer_object)
Order.php in src/DTO to carry data between processes. The main benefit is that it reduces
the amount of data that needs to be sent inside application and encapsulates parameters for
method calls (This can be useful if a method takes more than 4 or 5 parameters.). Also it is more
convenient than using associative array where you need to remember it’s indexes to get the
certain values (no autocomplete is provided).

OrderSignatureRepository this repository uses legacy PrestaShop classes,
it performs the request using the Db class. We have to do this because core objects
from PrestaShop do not use Doctrine entities, so we can’t use a Doctrine repository to manage them.Let’s create OrderSignaturePresenter class responsible for returning order customer data
in src/Presenter/:

Then let’s use Symfony Dependency Injection
(https://www.freecodecamp.org/news/a-quick-intro-to-dependency-injection-what-it-is-and-when-to-use-it-7578c84fa88f/).
and create services configuration for the above
classes in demovieworderhooks/config/services.yml.
The intention behind dependency injection is to achieve Separation of Concerns of construction and use of objects.
This can increase readability and code reuse, reduce dependencies, lead to more testable code.
It also reduces memory consumption as services are, by default, created once and shared
in the whole project.

Let’s create a twig templates in modules/demovieworderhooks/views/templates/admin/:
card.html.twig
{% trans_default_domain 'Module.Demovieworderhooks.Admin' %}
<div class="card">
<div class="card-header">
<h3 class="card-header-title">
{% block card_title %}

{% block card_body %}
<div class="col-lg">
<div class="display-4 text-center">
{{ signature.gender }} {{ signature.firstName }} {{ signature.lastName }}
</div>
<div class="text-center">
<img src="{{ signature.imagePath }}" alt="">
</div>
</div>
{% endblock %}
Let’s add several methods to DemoViewOrderHooks class.
getModuleTemplatePath - get the path of the templates folder.
<?php
/**
* Get path to this module's template directory
*/
private function getModuleTemplatePath(): string
{
return sprintf('@Modules/%s/views/templates/admin/', $this->name);
}
Render a twig template method:
<?php
/**
* Render a twig template.
*/
private function render(string $template, array $params = []): string
{
/** @var Twig_Environment $twig */
$twig = $this->get('twig');
return $twig->render($template, $params);
}
For each registered hook, you must create a non-static public method,
starting with the “hook” keyword followed by the name of the hook you want to use
(starting with either “display” or “action”). In our case: hookDisplayBackOfficeOrderActions
(read this article for more information).
We add this code at the bottom of the main module class demovieworderhooks.php
and also add the missing use statements for new classes.
<?php
/**
* Displays customer's signature.
*/
public function hookDisplayAdminOrderSide(array $params)
{
/** @var OrderSignatureRepository $signatureRepository */
$signatureRepository = $this->get(
'prestashop.module.demovieworderhooks.repository.order_signature_repository'
);
/** @var OrderSignaturePresenter $signaturePresenter */
$signaturePresenter = $this->get(
'prestashop.module.demovieworderhooks.presenter.order_signature_presenter'
);
$signature = $signatureRepository->findOneByOrderId($params['id_order']);
if (!$signature) {
return '';
}
return $this->render($this->getModuleTemplatePath() . 'customer_signature.html.twig', [
'signature' => $signaturePresenter->present($signature, (int) $this->context->language->id),
]);
}
The full main module file with dependencies could be:

and click the drop down near the disable button and select reset to reload the module with the newly
described symfony services.
