3. VariantGenerator¶

This is used to create all possible combinations of an object’s options and to create Variant models from them.

Example:

If an object such as a t-shirt has 2 options - Color and Size - with 3 possible values per option, then the generator will create 9 variants and assign them to the object.

The generator will ignore invalid variants or variants that already exist.

The Code

use Sylius\Component\Resource\Repository\RepositoryInterface;
use Sylius\Component\Variation\Generator\VariantGenerator;
use Sylius\Component\Variation\Model\VariableInterface;

/** @var RepositoryInterface $variantRepository */
$variantRepository = /*...*/

/**
 * From the example above, this would be the T-Shirt product.
 *
 * @var VariableInterface $variable
 */
$variable = /*...*/

$generator = new VariantGenerator($variantRepository);

// Generate all possible variants if they don't exist currently.
$generator->generate($variable)
