I have created an extension to access properties of context into twig templates of Prestashop
Setup
Create the file src/Twig/Extension/PsContext.php into module folder with the following content:
<?php
namespace MyModule\Twig\Extension;
class PsContext extends \Twig_Extension
{
/**
* {@inheritdoc}
*/
public function getFunctions()
{
return array(
new \Twig_SimpleFunction('from_context', [$this, 'getFromContext']),
);
}
/**
* {@inheritdoc}
*/
public function getName()
{
return 'ps_context';
}
/**
* {@inheritdoc}
*/
public function getFromContext(?string $property = '')
{
$context = \Context::getContext();
return array_reduce(
explode('.', $property),
function($o, $p) {
return is_numeric($p) ? ($o[$p] ?? null) : ($o->$p ?? null);
},
$context
);
}
}
Add Twig extension to services of your module.
Add following lines to services.yml:
mymodule.twig.ps_context_extension:
class: MyModule\Twig\Extension\PsContext
tags:
- { name: twig.extension }
Usage
e.g.
Hello, I'm { { from_context('employee.firstname') } }.
{ % if from_context('employee.id_profile') is constant('_PS_ADMIN_PROFILE_') % }
Hello, I'm administrator.
{ % endif % }
