How to add a custom page with cross-sell products

magento.stackexchange https://magento.stackexchange.com/questions/122348

Question

You wouldn't believe how much time I've spent researching/trying to make this happen. All I want is to have an extra page come up in the order process after the product page asking the customer which cross-sell product(s) they want to add to their order (I would call them up-sell but I guess the Magento lingo is "cross-sell"). I really find it unbelievable that more businesses don't want this (I think "up-selling" can greatly increase profits and what's built into Magento does not really work so well (I have more than 20 "Cross-sell" products and they don't even fit/show on there).

I'm using Magento ver. 1.9.1.0.

I just installed the Porto Theme #11 if that makes a difference

NEW INFO: I've been trying to implement this but no luck so far. I even have someone helping me now but we can't figure it out. Can someone please give step-by-step instructions on how to do this? (ANY solution would be much appreciated).

I would like it to work similar to what proflowers.com has (see the enclosed screenshot): enter image description here

They have this page come up as the next step AFTER customer adds a product to the cart (clicks on PROCEED TO CHECKOUT)

All the cross-sell products are ALWAYS the SAME for everyone (every product ordered)

Edited on November 15th, 2016:

The solution that got awarded the 100 reputation actually works. Anyone trying to do what I am trying to do should download the files and upload them into your root directory and then add the following code in your app/code/community/TM/SuggestPage/controllers/IndexControlle‌​‌​r.php file:

$block2 =  $this->getLayout()->createBlock('checkout/cart_coupon')->setTemplate('checkout/cart/coupon.phtml');
$this->getLayout()->getBlock('content')->append($block2);

I am still trying to figure out how to display 12 products on the special Cross-sell page instead of just 4. Accoring to @MurtuzaZabuawala - this should be done by modifying the crosssell.phtml file in:

app/design/frontend/YourPackge/YourTheme/checkout/cart/

I found my crossell.phtml here:

/public_html/app/design/frontend/smartwave/porto/template/checkout/cart

(I hope it's the right one - I have the Porto Theme installed)

Here is what it looks like:

<?php
/**
 * Cart cross sell items template
 *
 * @see Mage_Checkout_Block_Cart_Crosssell
 */
$store = Mage::app()->getStore();
$code  = $store->getCode();
$aspect_ratio = Mage::getStoreConfig("porto_settings/category/aspect_ratio",$code);
$ratio = ($aspect_ratio || (!$aspect_ratio && Mage::getStoreConfig("porto_settings/category/ratio_width",$code) == 0))?1:(Mage::getStoreConfig("porto_settings/category/ratio_height",$code)/Mage::getStoreConfig("porto_settings/category/ratio_width",$code));
?>
<?php if($this->getItemCount()): ?>
<div class="crosssell">
    <h2><?php echo $this->__('Based on your selection, you may be interested in the following items:') ?></h2>
    <ul id="crosssell-products-list" class="row">
    <?php foreach ($this->getItems() as $_item): ?>
        <li class="item col-sm-6 col-md-3">
            <a class="product-image" href="<?php echo $_item->getProductUrl() ?>" title="<?php echo $this->escapeHtml($_item->getName()) ?>"><img src="<?php echo $this->helper('catalog/image')->init($_item, 'thumbnail')->resize(84,84*$ratio); ?>" width="84" height="<?php echo 84*$ratio ?>" alt="<?php echo $this->escapeHtml($_item->getName()) ?>" /></a>
            <div class="product-details">
                <h3 class="product-name"><a href="<?php echo $_item->getProductUrl() ?>"><?php echo $this->escapeHtml($_item->getName()) ?></a></h3>
                <?php echo $this->getPriceHtml($_item, true) ?>
                <button type="button" title="<?php echo $this->__('Add to Cart') ?>" class="button btn-cart" onclick="setLocation('<?php echo $this->getAddToCartUrl($_item) ?>')"><span><span><?php echo $this->__('Add to Cart') ?></span></span></button>
                <ul class="add-to-links">
                    <?php if ($this->helper('wishlist')->isAllow()) : ?>
                        <li><a href="<?php echo $this->getAddToWishlistUrl($_item) ?>" class="link-wishlist"><?php echo $this->__('Add to Wishlist') ?></a></li>
                    <?php endif; ?>
                    <?php if($_compareUrl=$this->getAddToCompareUrl($_item)): ?>
                        <li><span class="separator">|</span> <a href="<?php echo $_compareUrl ?>" class="link-compare"><?php echo $this->__('Add to Compare') ?></a></li>
                    <?php endif; ?>
                </ul>
            </div>
        </li>
    <?php endforeach; ?>
    </ul>
    <script type="text/javascript">decorateList('crosssell-products-list', 'none-recursive')</script>
</div>
<?php endif; ?>

EDITED December 2nd, 2016:

This is a great solution which works perfect especially if you want to assign different cross-sell products to each product individually. In my case - I want all of my products to have the EXACT SAME cross-sell products and I want to be able to change that depending on the season so I decided to have the extra step in the check-out (solution provided by Murtuza Zabuawala below) display products from a special category I created just for this reason. Murtuza Zabuawala did a great job with. I'm just missing the final step here:

When I put in the code which should display the products from a specific category:

$block = $this->getLayout()->createBlock('catalog/product_list')->set‌​CategoryId(157)->set‌​Template('catalog/pr‌​oduct/list.phtml'); $this->getLayout()->getBlock('content')->append($block);

I get the following Error message:

my

app/code/community/TM/SuggestPage/controllers/IndexControlle‌​‌​r.php

looks like this:

<?php

class TM_SuggestPage_IndexController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()


{

    $this->loadLayout()
        ->_initLayoutMessages('checkout/session')
        ->_initLayoutMessages('catalog/session');



$block2 =  $this->getLayout()->createBlock('checkout/cart_coupon')->setTemplate('checkout/cart/coupon.phtml');
$this->getLayout()->getBlock('content')->append($block2);


    $_product = Mage::getModel('catalog/product')->load(1); //here 1 is product Id
    $block = $this->getLayout()->createBlock('catalog/product_list')->set‌​CategoryId(157)->set‌​Template('catalog/pr‌​oduct/list.phtml'); $this->getLayout()->getBlock('content')->append($block);



    $this->renderLayout();
    }
}

When I tried the following code instead (in: app/code/community/TM/SuggestPage/controllers/IndexControlle‌​‌​r.php ):

**

$category = Mage::getModel('catalog/category')->load(190);  
   $block = $this->getLayout()->createBlock('catalog/product_list')->set‌​Category($category)->set‌​Template('catalog/pr‌​oduct/list.phtml'); $this->getLayout()->getBlock('content')->append($block);

**

    $category = Mage::getModel('catalog/category')->load(190);  
   $block = $this->getLayout()->createBlock('catalog/product_list')->set‌​Category($category)->set‌​Template('catalog/pr‌​oduct/list.phtml');

$this->getLayout()->getBlock('content')->append($block);

    $this->renderLayout();
    }
}

EDITED December 29th, 2016:

The solution posted by Murtuza Zabuawala is great! The only thing I still need to do is put some code in to call up (display) products from a specific category instead of the actual cross-sell items. Any idea how to do that?

Was it helpful?

Solution

Install below extension that will help you to create extra page after cart

https://github.com/tmhub/suggestpage

above extension add extra page after cart and that page you will add these code and you will get cross-sell product data

change your indexController indexAction as below 

public function indexAction()
{
    $this->loadLayout()
        ->_initLayoutMessages('checkout/session')
        ->_initLayoutMessages('catalog/session');

    $_product = Mage::getModel('catalog/product')->load(1); //here 1 is product Id
    $block =  $this->getLayout()->createBlock('checkout/cart_crosssell')->setProduct($_product)->setTemplate('checkout/cart/crosssell.phtml');
    $this->getLayout()->getBlock('content')->append($block);

    $this->renderLayout();
}

and for your 4 product issue please check in your app/design/frontend/YourPackge/YourTheme/checkout/cart/crosssell.phtml file any condition who breaks for loop after four product then change it.

to increase limit for cross-sell product follow this quick step

1) copy app/code/core/Mage/Checkout/Block/Cart/Crosssell.php file to app/code/local/Mage/Checkout/Block/Cart/Crosssell.php

2) find this line and increase limit as per your need protected $_maxItemCount = 4;

OTHER TIPS

We've implemented something on a client website where you click on proceed to checkout you land on a page before it asking you to add free samples, these are pulled in from a category but would be just as easy to pull in some cross-sell/related products.

Essentially code wise what would have to happen is, a module would have to listen for the event controller_action_predispatch_checkout_onepage_index and redirect the user to a page built by that module with the products you require, then after that set a session flag to say this user has already seen this up-sell page and allow them through to the checkout.

I'm not sure if there are any modules out there that currently do this.

As a brief example we have this as our xml:

<controller_action_predispatch_checkout_onepage_index>
    <observers>
        <namespace_module>
            <class>namespace_module/observer</class>
            <method>redirectToUpsellOnCheckout</method>
        </namespace_module>
    </observers>
</controller_action_predispatch_checkout_onepage_index>

Edit 15/11/16 Here's what i have so far, still needs some amends:

                </dc_crosssells>
            </updates>
        </layout>
    </frontend>
</config>

app/code/community/Dc/Crosssells/Model/Observer.php

<?php
class Dc_Crosssells_Model_Observer
{
    public function controllerActionPredispatchCheckoutOnepageIndex(Varien_Event_Observer $observer)
    {
        if(Mage::getSingleton('core/session')->getCrossSellFlag()) {
            Mage::app()->getResponse()->setRedirect(Mage::getBaseUrl() . 'before-you-checkout');
            Mage::getSingleton('core/session')->setCrossSellFlag('true'); 
        }
    }

}

That above is enough to redirect the user to another page after hitting going to checkout. Would need to set a flag within this observer to the session and then check if that flag exists, if it does, do the redirect.

Then we can create a controller this will be our "before-you-checkout" page, it creates/renders the layout using a block from the template. app/code/community/Dc/Crosssells/controllers/IndexController.php

<?php
class Dc_Crosssells_IndexController extends Mage_Core_Controller_Front_Action
{

    public function indexAction()
    {
        $this->loadLayout(array('default'));

        $block = $this->getLayout()->getBlock('before.you.buy')->getBlockHtml('before.you.buy');
        $this->getLayout()->getBlock('content')->append($block);
        $this->_initLayoutMessages('core/session');
        $this->renderLayout();
    }

}

We have a block class to house the functions needed by the frontend block, I haven't fully tested this, it is supposed to return a product collection filtered by the category you should have created in the backend, in my case it's category 292. app/code/community/Dc/Crosssells/Block/BeforeYouBuy.php

<?php
class Dc_Crosssells_Block_BeforeYouBuy extends Mage_Core_Block_Template
{
    public function getCrossSellProductsFromCategory()
    {
        $category = Mage::getModel('catalog/category')->load(292);

        $products = Mage::getModel('catalog/product')->getCollection()
            ->addCategoryFilter($category)
            ->addAttributeToSelect('*');

        return $products;

<?php $products = $this->getCrossSellProductsFromCategory();

foreach($products as $item) {
    echo $item->getName(). '<br />';
}

I haven't fully tested this code properly yet and still needs some work to actually display the products properly with add to cart buttons etc. I've put it in a github repo here: https://github.com/DanCarlyon/MagentoCrossSellPage

Feel free to download and have a play with it.

Try this module:

File : app\etc\modules\Rkt_CrossSell.xml

true community File : app\code\community\Rkt\CrossSell\etc\config.xml

1.0.0 Rkt_CrossSell_Helper Rkt_CrossSell_Block rkt_crossell.xml File : app\code\community\Rkt\CrossSell\Block\Catalog\Product\View\Crosssell.php

/**
 * Get crosssell items
 *
 * @return array
 */
public function getItems()
{
    $items = $this->getData('items');
    if (is_null($items)) {
        $items = $this->getProduct()->getCrossSellProducts();
        $this->setData('items', $items);
    }
    return $items;
}

} File : app\code\community\Rkt\CrossSell\Helper\Data.php

} File : app\design\frontend\base\default\layout\rkt_crossell.xml

Now in your view.phtml add this code in the appropriate position

getChildHtml('crosssell') ?> Now clear your cache. Double check evey file name and file paths are correct. Then you are good to go

You can add a block on product page or else call the phtml file inside a cms page.

Try Below code For category rendering

   $category = Mage::getModel('catalog/category')->load(157);  
   $block = $this->getLayout()->createBlock('catalog/product_list')->set‌​Data('category_id',$category)->set‌​Template('catalog/pr‌​oduct/list.phtml'); 
   $this->getLayout()->getBlock('content')->append($block);
