Description
Allows OpenCart code to use Eloquent/Query Builder methods to work with database tables instead of ‘raw’ SQL queries.

Version support
OpenCart 2/3: OCMOD modifier corrects catalog/controller/startup/startup.php and admin/controller/startup/startup.php.
OpenCart 4: register startup in module install() method, without core edits.

Requirements
PDO extension for MySQL (pdo_mysql)

Usage
In the file system/library/eloquent.php, the QB class
class QB extends \Illuminate\Database\Capsule\Manager {}

The QB class is available immediately:
// via the facade
$users = QB::table('user')->get();

The capsule instance is also stored in the registry:
$this->registry->set('eloquent', EloquentDB::getCapsule());
// and in controllers
$qb = $this->eloquent;
$orders = $qb->table('order')->where('status',1)->get();
