I want to disable USPS on the frontend if a product's length is over 12" (the max size USPS box we use).

I understand there is an extension, Amasty Shipping Restrictions that gets high praise, but this is much more complex than I require.

Is there a straightforward way to program this into my checkout rules?

Solution Logic

I set up a solution that iterates through each item in a customer's cart, check's each item's height attribute, then if any item is over a given length, it raises the flag(s) for whatever shipping method can't ship something that length, and hides the shipping method(s) from the customer's view.

I configured this solution to work for USPS (max length 12", limited by the largest box our store offers), UPS (max length 108" per UPS Ground website), and FedEx (max length 165" per FedEx website).

To reiterate, if any one item is over the maximum length, then that shipping method is disabled for the entire cart. I injected this logic check into the "View Cart" and "Onepage Checkout" pages to hide any unavailable shipping methods dynamically.

Files changed

/app/design/frontend/base/default/template/checkout/onepage/shipping_method/available.phtml

/app/design/frontend/rwd/default/template/checkout/cart/shipping.phtml

PHP added

Both Files

$upsAllowed = true;         // UPS allowed by default   (unless height attrib greater than 165)
foreach ($cart->getAllItems() as $item) {
    $storeId = 1;           // Mbs Standoffs store code
    $attributeId = 'height';// Height attribute code
    $qty += $item->getQty();// Keep track of total item quantity in cart
    $productId = $item->getProduct()->getId();
    $productLength = Mage::getResourceModel('catalog/product')->getAttributeRawValue($productId, $attributeId, $storeId);

  • Thanks for sharing this but can u please, let me know which code i have to place in shipping_method.phtml and which code we have i to place in shipping.phtml. If you can help me out. Thanks in Advance – LR Soni Nov 2 '15 at 17:11
  • I updated the answer with a more clear breakdown of what code goes where. It is somewhat customized for how our store rules are. It doesn't offer USPS Small Flat Rate ever. It doesn't offer Medium for orders with a total quantity over 50. It doesn't offer Large when quantity over 100. This gives you an idea of how it can be used to modify what your user sees. – travisw Nov 3 '15 at 14:00
  • Thanks for your time and thanks for making the changes in the code. Hope may a have a good day Ahead !! :) Cheers :p – LR Soni Nov 3 '15 at 14:02
  • I am trying to make this work for our requirement, which is making certain shipping methods unavailable for certain products. I created a new attribute called "no_shipping" for this purpose with options "Yes" and "No". I replaced this with the "length" attribute from your example and works to make the main carrier unavailable. The issue is that we use webshopapps' premium matrix rates for all our shipping methods. Is there a way that I can block one method out of the main carrier, which is premiumrate in our case. Can one restrict based on the shipping methods title instead of carrier code? – Sparc Jul 20 '16 at 2:09

Take a look at http://projectamplify.com/insight/remove-magento-shipping-methods-if-free-shipping-available/

In

app/ design/ frontend/ default/ YOURTEMPLATE/ template/ checkout/ onepage/ shipping_method/ available.phtml

You could check your quote items to see if any of these products exist, if so remove shipping method (or create an observer for item add/remove and update a custom added field in sales_flat_quote then check the value of this field)

unset($_shippingRateGroups["usps"]);

Also take a look at http://inchoo.net/magento/how-to-hide-shipping-method-on-magento-frontend-but-leave-it-on-in-admin-area/

You can try Mconnect Shipping Restriction Magento 2 Module as it allows you to create a variety of shipping rules using various limitation criteria based on customers, shopping cart, and product attributes.

Recently I needed to do something similar. In Magento 2 if you extend the shipping class (\Magento\Shipping\Model\Shipping) in an extension, you can access attributes using the method explained in this answer: Magento 2 make product attribute available in QuoteItem
