Support sorting product attributes by attribute weight

// Sort the add to cart form attributes by it's weight. $attribute_storage = \Drupal::entityTypeManager()->getStorage('commerce_product_attribute_value'); foreach (Element::children($form['purchased_entity']['widget']) as $widget_index) { $widget = &$form['purchased_entity']['widget'][$widget_index]; foreach (Element::children($widget['attributes']) as $attribute_code) { $attribute = &$widget['attributes'][$attribute_code]; if (count($attribute['#options']) <= 1) { continue; } $attributes = $attribute_storage->loadMultiple(array_keys($attribute['#options'])); uksort($attribute['#options'], function ($a, $b) use ($attributes) { return $attributes[$a]->getWeight() > $attributes[$b]->getWeight() ? 1 : -1; }); }

I had to resort to something like this:

<?php

/**
 * @file
 */

use Drupal\Core\Form\FormStateInterface;
use Drupal\commerce_product\Entity\Product;
use Drupal\commerce_product\Entity\ProductAttribute;
use Drupal\commerce_product\Entity\ProductAttributeValue;

/**
 * Implements hook_form_FORM_ID_alter().
 *
 * Set stores when creating a new product.
 */
function mymodule_form_alter(&$form, FormStateInterface $form_state, $form_id) {

    // Validate if its a add to cart form.
    if (str_starts_with($form_id, 'commerce_order_item_add_to_cart_form_commerce_product_')) {
        // Validate if the form has a select size element.
        if (isset($form['purchased_entity']['widget'][0]['attributes']['attribute_size']['#options'])) {
            // Get the size options.
            $old_options = $form['purchased_entity']['widget'][0]['attributes']['attribute_size']['#options'];
            // Do nothing if there are no sizes.
            if (empty($old_options)) {
                return;
            }

            // Sort the size select options by the attributes' weight.
            $product_attribute = ProductAttribute::load('size');
            if (!$product_attribute) {
                return;
            }
            $product_attribute_values = $product_attribute->getValues();
            if (empty($product_attribute_values)) {
                return;
            }
            $new_options = [];
            foreach ($product_attribute_values as $key => $product_attribute_value) {
                if (array_key_exists($key, $old_options)) {
                    $new_options[$key] = $product_attribute_value->name->value;
                }
            }
            $form['purchased_entity']['widget'][0]['attributes']['attribute_size']['#options'] = $new_options;
        }
        
    }
}

hm... I get the request, however this would essentially mean that the variations order is no longer respected if we change this... Currently variations can be reordered from the product variations tab, if we change this, this would essentially make the variations ordering "useless".
