How to Add Multiple Products to Magento Cart from External Source

cartexternalmagento-1.7magento-1.8shopping-cart

I have to add multiple items into magento cart from out side of magento (external website), through /path/to/app/checkout/cart/add?product=[id]&qty=[qty] this method I can add one product to the cart.

Can anyone suggest how to do it?

There is a way, but you cannot add quantities to the rest of the products. They will be added in minimum qty. (most probably 1).

/checkout/cart/add/?product=[id]&qty=[qty]&related_product=[id2],[id3],...,[idN]

It works even if products with ids id2, .., idN are not actually related products to the main product.
Click this for demo:http://demo.magentocommerce.com/checkout/cart/add/?product=51&qty=2&related_product=17,18.

But be careful. In ce1.8 this doesn't work. Actually just adding a simple product to the cart doesn't work anymore (I mean this checkout/cart/add?product=[id]&qty=[qty]). Starting with this version the form_key is required when adding something to the cart.
Since this form_key depends on the session you may want to create your own controller and action that receives the products to be added to the cart and redirects to checkout/cart/add?product=[id]&qty=[qty]&form_key=FORM_KEY_HERE

The code looks pretty strait forward (and works locally with a sample configurable product). My guess is that you have a mal-formed $params array for those custom options.

It expects something along the lines of this...

$params = array(
    'product' => 1,
    'qty' => 1,
    'options' => array(
        26 => "value",
        42 => "another value here",
        71 => "yav"
)
);

What kind of custom option type is it that requires the value to be an array?

You will have to create a custom module in magento.

Create a file app/etc/MyExtension_AddProductFromUrl.xml

<config>
    <modules>
        <MyExtension_AddProductFromUrl>
            <active>true</active>
            <codePool>local</codePool>
            <depends>
                <Mage_Checkout/>
            </depends>
        </MyExtension_AddProductFromUrl>
    </modules>
</config>

Create a file app/code/local/MyExtension/AddProductFromUrl/etc/config.xml

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <MyExtension_AddProductFromUrl>
            <version>0.1.0</version>
        </MyExtension_AddProductFromUrl>
    </modules>

    <frontend>
        <routers>
            <checkout>
                <args>
                    <modules>
                        <MyExtension_AddProductFromUrl before="Mage_Checkout">MyExtension_AddProductFromUrl</MyExtension_AddProductFromUrl>
                    </modules>
                </args>
            </checkout>
        </routers>
    </frontend>
</config>

Create a file app/code/local/MyExtension/AddProductFromUrl/controllers/CartController.php

<?php
    require_once 'Mage/Checkout/controllers/CartController.php';
    class MyExtension_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();
        }
    }
?>
