While working on a module to integrate Magento with Foxy Cart’s awesome checkout service, I came across the need to use Guzzle in my Magento module. Because I am building the initial version of this module using Magento 1.x, I could not be certain that users of this module would have Composer available.

To accomplish this task, I had to put together a basic autoloader.php class that would serve as my autoloader for not only Guzzle, but any library that it or my script requires.

To start, I create a Magento module like any other module. In my app/code/Namespace/Module folder, I create a folder named “lib” for my includes. In this folder, I added the following libraries:

1. Doctrine/Common/Cache
2. GuzzleHttp
3. React/Promise
4. Riimu/Kit

I also added a file named autoloader.php. I started with the proper autoloader.php from the zip file download of GuzzleHttp, but then added all the other library includes that I may need. The resulting file is below:

spl_autoload_register(function ($class) use ($mapping) {
if (isset($mapping[$class])) {
require $mapping[$class];
}
}, true);

require __DIR__ . ‘/React/Promise/functions.php’;

 

In my class that needs to use Guzzle, I then add this to the top of the class file:


require Mage::getModuleDir('','Jamersan_Foxy').DS.'lib'.DS.'autoloader.php';
use GuzzleHttp\Subscriber\Cache\CacheSubscriber;
use GuzzleHttp\Client;

That should do it! After adding these items, you should now be able to use Guzzle in your Magento module!
