Get Magento permalink URL for cart?

Question

I used to use Shopify and the permalink to fill a cart was something like: http://domainname.myshopify.com/cart/370374:1,377854:1,37067790:1

Is there a similar way to do this with Magento? So far I've tried:

https://domainname.com/checkout/cart/add?product=99750&qty=1

But they don't appear to work.

Answer 1

in this https://domainname.com/checkout/cart/add?product=99750&qty=1 you are missing form_key parameter

It will look likes, https://domainname.com/checkout/cart/add?product=99750&qty=1&form_key=crtH4Ol3DYNeSFr5

form_key is dynamically generated key, you can get it as below and pass it to url

$form_key = Mage::getSingleton('core/session')->getFormKey();

Pass $form_key value while building url

$url = "https://domainname.com/checkout/cart/add?product=99750&qty=1&form_key=".$form_key;

Use above $url in your action call
