Hello all,

can someone please advise me on the right way to add helper files in the modules? For example adding a MyModuleHelper.php with static helper functions in a module named MyModule. How would you do that? Thanks in advance, Sven

Build a service for that and get it as a dependency where ever you use it. Calling something with static will make it hard to test and couple all using modules to exact these helper implementation.

An example for a service would be the \Spryker\Service\UtilText\UtilTextService

If your "helper" is only used inside the module it is part of create a class and inject it were needed into the constructor through the factory:

<?php

namespace Pyz\Zed\YourBundle\Business;

interface HelperInterface {}

class Helper implements HelperInterface {}

class Using
{
    public function __construct(HelperInterface $helper)
    {
        $this->helper = $helper;
    }

    public function doSomething()
    {
        $this->helper->doSomething();
    }
}

class YourBundleBusinessFactory
{
    public function createUsing()
    {
        return new Using($this->createHelper());
    }

    public function createHelper()
    {
        return new Helper();
    }
}

If you use a service your factory just looks a little different as you need to get the dependencies from the dependency provider:
