I want to add custom option type as image to quoteitem in checkout review page using observer which observer event is controller_action_predispatch_checkout_onepage_index and it fires when goes to checkout page.

In event call in config.xml


and then in my Observer.php

public function salesCollectBefore($observer)
    $quote_items = $quote->getItemsCollection();
        foreach ($quote_items as $item) {
        $customisation['upload_logo'] = "test.png";
            $additionalOptions = array(
                    'code'  => 'my_code',
                    'label' => 'Logo',
                    'print_value' =>  '<a href="'.Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_MEDIA).$customisation['upload_logo'].'">'logo'</a>',
                    'option_value' => '<a href="test">'.$customisation['upload_logo'].'</a>',
                    'value' => $customisation['upload_logo'].
                     'code'  => 'additional_options',
                     'value' => serialize($additionalOptions),


It does not allow me to show as a link to download the image, It shows only the image name . I want to add the image link in order review page and it should be downlodable from the link. How can I achieve this. Can anyone help here? Plz...

    There is no custom template for module. Default magento template works here.

controller_action_predispatch_checkout_onepage_index event does not given the Current Quote object as it params.

If want current quite on this event this ,you need to call





public function salesCollectBefore($observer)
    /* add this */   
    $quote_items = $quote->getItemsCollection();

So,you cannot get Currentquote object from $observer.As per as magento controller_action_predispatch_checkout_onepage_index event current.

from this event you can only get onepageController object

   Mage::dispatchEvent('controller_action_predispatch_' . $this->getFullActionName(),
            array('controller_action' => $this));
