# PrestaShop Service Container for Modules

This repository includes the service container from Symfony that you can use in your PrestaShop Module.

## Pre-requisites

You should install this library only on a PrestaShop environment and with PHP 5.6.0 minimum.

## Installation

```
composer require prestashop/module-lib-service-container
```

When this project is successfully added to your dependencies, you can add the new ServiceContainer to your module and use it.

## Usage

To use this library, it's simple :
 - First, declare your new service Container in your root module PHP file (like mymodule.php at your root project folder) :
```
    /**
     * @var ServiceContainer
     */
    private $serviceContainer;
```
- And instantiate it in the constructor with the module name and its local path :
```
$this->serviceContainer = new ServiceContainer($this->name, $this->getLocalPath());
```
- You can add a new function on your root module PHP file, like getService, to retrieve your service name in the new service container :
```
    /**
     * @param string $serviceName
     *
     * @return mixed
     */
    public function getService($serviceName)
    {
        return $this->serviceContainer->getService($serviceName);
    }
```
- Then, you have to declare your service in the services.yml file. You must declare your services in the config/ folder.
We split the services in two folders in the config : /front and /admin folders. So the tree should be like :
```
/mymodule
    /config
        /front
            services.yml
        /admin
            services.yml
        common.yml
```
- Of course, you can include a common file, with common services that are use in front and admin project by an import in the services.yml file :
```
imports:
  - { resource: ../common.yml }
```
Now you can add your services in the services.yml like you were in a Symfony project ;)
