title: magento add bundle item directly to cart from upsell - predefined options
body: <p>I'm trying to add a bundled item to the cart from the upsell area with the options preselected - so it will take you directly to the cart and not the item page, and am using the following url:</p>
  
  <p><code>Mage::$this-&gt;helper('checkout/cart')-&gt;getAddUrl($_link)</code></p>
  
  <p>concatenated with, for example:</p>
  
  <p><code>?bundle_option[14][]=16&amp;bundle_option[15][]=17&amp;bundle_option[16][]=19&amp;</code></p>
  
  <p>This url then adds the item to the cart, but with the warning:</p>
  
  <blockquote>
    <p>Some of the products below do not have all the required options. Please edit them and configure all the required options.</p>
  </blockquote>
  
  <p>And will not let me continue to the checkout. It also contains the usual add to cart success message.</p>
  
  <p>If I add the item from it's own page (with all default options) it works fine.</p>
  
  <p>I have it set up as per <a href="https://stackoverflow.com/questions/5911738/add-bundle-product-to-cart-without-having-to-specify-the-options">Add bundle product to cart without having to specify the options</a>, with required radio buttons and defaults selected.</p>
  
  <p>Also, adding <code>options_bundle_qty[...</code> options to the url doesn't help.</p>

    <p><strong>Update</strong>: I have exactly the same setup on a 1.4 and a 1.6 install, it is working in 1.4, but not 1.6</p>
