Magento - Add a product to the cart via query string without form_key parameter

Question

I\'ve just installed Magento Community Edition ver 1.8.0.0 (default settings).

System -> Configuration -> Sales -> Checkout -> Checkout Options

Answer 1

What I actually did in the end was compare the new changes with the old code and I discovered the add to cart button was set to type="button" and was not submitting.

Changing the button to simply type="submit" and no other changes actually made it work this is in [theme]/template/catalog/product/view/addtocart

may have to move from base folder if non-existent

Answer 2

This is how I am doing it in Magento 1.8.1

<a href="<?= $this->getAddtoCartUrl($_product, array('qty' => $_price['price_qty'])) ?>">

See http://docs.magentocommerce.com/Mage_Catalog/Mage_Catalog_Block_Product_Abstract.html#getAddToCartUrl

Answer 3

Use "Add To Cart" link for your product any where on a Magento website::

The following code may helpful:

$product = Mage::getModel('catalog/product')->load($YourProductID);

echo Mage::helper('checkout/cart')->getAddUrl($product);

From magento 1.8 need to add form key $formKey = Mage::getSingleton('core/session')->getFormKey();?> to url

Answer 4

This works best for me in Magento C 1.8

<?php
 
$formKey = Mage::getSingleton('core/session')->getFormKey();?>

<form action="/checkout/cart/add/product/<?php echo $productid; ?>" method="post">
    <input type="hidden" name="form_key" value="<?php echo $formKey; ?>" />

    <input type="text" name="qty"> QTY

    <input type="submit" value="Add to basket" />
</form>

Answer 5

What I did is to override the Magento CartController with a custom module. I created a file inside: \app\code\local\Namespace\AddProductFromUrl\controllers\Checkout\CartController.php

<?php
    require_once 'Mage/Checkout/controllers/CartController.php';
    class Namespace_AddProductFromUrl_Checkout_CartController extends Mage_Checkout_CartController {
        # overloaded addAction
        public function addAction() {        
            // generate form_key if missing or invalid
            if (!($formKey = $this->getRequest()->getParam('form_key', null)) || $formKey != Mage::getSingleton('core/session')->getFormKey()) {
                $this->getRequest()->setParams(array('form_key' =>Mage::getSingleton('core/session')->getFormKey()));
            }        

            // do parent actions
            parent::addAction();
        }
    }
?>

(The module need to have config.xml and enabled under etc/modules/ as for every magento custom module. Change Namespace with the one you use.)

That works perfectly just like magento 1.7 and with minimal impact; the form_key is generated if missing and that's it.

Answer 6

The following can be used with qty set:

$product = Mage::getModel('catalog/product')->load($getProductID);

echo Mage::helper('checkout/cart')->getAddUrl($product, array('qty'=>$getQty));
