How to get the ordered size of a product In Magento 2

Question

I tried to get the size of a product/products that was ordered.

So let's say a product has 5 sizes: S, M, L, XL,XLL and when i made the order the product x was bought with the size M.

When i load the order i want to get this "M" size in my code.

This is how i load my order:

$order = $_objectManager->create('Magento\Sales\Model\Order')->load($orderID);

 foreach ($order->getAllItems() as $item) {
      $product = $_objectManager->create('Magento\Catalog\Model\Product')->load($item->getProductId());
... here i want to get the size
}

Does anyone know how to do that? because i didn't find nothing relevant.

Thank you!

Answer 1

You can try:

$order = $_objectManager->create('Magento\Sales\Model\Order')->load($orderID);

$items = $order->getAllVisibleItems();
// $items = $order->getAllItems(); // all items


foreach ($items as $item) {
    $options = $item->getProductOptions(); // all product options       
 }

EDIT:

If you can try not to use ObjectManager directly. It defeats the purpose of dependency injection.

Answer 2

Try this:

$order = $_objectManager->create('Magento\Sales\Model\Order')->load($orderID);
foreach ($order->getAllItems() as $item) {
     $productOptions = unserialize($item->getProductOptions());
     echo "<pre>";
     print_r($productOptions); 
     // check the [attributes_info] for the attributes info 
}

OR

$order = $_objectManager->create('Magento\Sales\Model\Order')->load($orderID);
foreach ($order->getAllItems() as $item) {
      $product = $item->getProduct();
      $size = $product->getSize(); // get size value
      if($product->getSize()) {
            echo $product->getAttributeText('size'); // get size label  
      }

}
