Probably you know it’s possible to add a product to the cart via querystring, but may be you prefer code a new module for your needs using Magento objects and methods.

So adding a simple product is easy:

...

$cart = Mage::getSingleton('checkout/cart');

// start adding the product

try {

$cart->addProduct($product, array('qty' => 1));

// save the cart

$cart->save();

$result = null;

} catch (Mage_Core_Exception $e) {

$result = $e->getMessage();

}

But how to add a Downloadable product with its right link? Just try this, it’s a controller I used to integrate an “add to cart” API:

public function cartaddAction()
{
$productId  = (int) $this->getRequest()->getParam('id');
$callback  = (string) $this->getRequest()->getParam('callback');

$cart = Mage::getSingleton('checkout/cart');

// call the Magento catalog/product model
$product = Mage::getModel('catalog/product')
// set the current store ID
->setStoreId(Mage::app()->getStore()->getId())
// load the product object
->load($productId);

$links = Mage::getModel('downloadable/product_type')->getLinks( $product );

foreach ( $links as $link )
if ( preg_match("/epub/i", $link->getTitle()) )
$linkId = $link->getLinkId();

// Here is the trick to add the right link id

$input = array( 'qty' => 1, 'links' => array( $linkId ) );
$request = new Varien_Object();
$request->setData($input);

// start adding the product
try {
$cart->addProduct($product, $request);
// save the cart
$cart->save();

$result = null;
} catch (Mage_Core_Exception $e) {
$result = $e->getMessage();
}

// very straightforward, set the cart as updated
Mage::getSingleton('checkout/session')->setCartWasUpdated(true);
}

Here is how to get a collection of products best sold in a given date range (could be daily, monthly, weekly, etc…)

<ul>
<?php
$from = date("Y-m-d H:i:s", (time()-2592000));
$to = date("Y-m-d H:i:s", time());

$_productCollection = Mage::getResourceModel('reports/product_collection')
->addAttributeToSelect('*')
->addOrderedQty($from, $to, true)
->addAttributeToFilter('status', 1)
->setOrder('ordered_qty', 'desc')
->getSelect()->limit(10)->query();

foreach ( $_productCollection as $prod ) :
$_product = Mage::getModel('catalog/product');
$_product->load($prod['entity_id']);
($i%2) ? $even = "class='even-li'" : $even = "";
?>
<li <?php echo $even ?>>
<div><a href="<?php echo $this->getUrl($_product->getUrlPath()) ?>" title="View <?php echo $_product->name ?>"><img src="<?php echo $this->helper('catalog/image')->init($_product, 'image')->resize(48); ?>" alt="<?php echo $_product->name ?>"  /></a>
<a href="<?php echo $this->getUrl($_product->getUrlPath()) ?>" title="View <?php echo $_product->name ?>"><?php echo Mage::helper('core/string')->truncate($_product->name, 50) ?></a>
<p><?php echo Mage::helper('core/string')->truncate(strip_tags($_product->description), 130); ?></p></div>
</li>
<?php
endforeach;
?>
</ul>

You know there is this problem with Magento 1.4.* and 1.5.*, if you are using Paypal Express as payment method and your customer is a new one, when she/he complete the order this is without account association (Customer Group 0 USER NOT LOGGED IN) and the new customer is not created.

To solve this problem you have to install this useful extension: https://github.com/onestepcheckout/PaypalRegister

Follow the README and finally you can get registered users with Paypal Express too.

You know you will need, before or after, to add your own custom RSS feeds to your Magento.
For example, I needed to create some custom RSS Feeds to list bestseller products by date (bestseller weekly, monthly, etc…)
How to do it? It’s quite complex but not so much if you follow this mini tutorial:

First of all, you need to setup a new namespace directory under your “local” dir, this will overwrite your current RSS Mage methods but not all.

So, create your directory app/local/Simplicissimus/Rss. (change Simplicissimus with your own Namespace and change it everywhere)

Create inside it the following directories:

• Block
• Block/Catalog
• controllers
• etc

Starting with the configuration XML, you need to create a file etc/config.xml like this:

<?xml version="1.0"?>
<config>
<modules>
<Simplicissimus_Rss>
<version>0.1.0</version>
</Simplicissimus_Rss>
</modules>
<global>
<blocks>
<rss>
<rewrite>
<list>Simplicissimus_Rss_Block_List</list>
<catalog_category>Simplicissimus_Rss_Block_Catalog_Category</catalog_category>
<catalog_bestseller>Simplicissimus_Rss_Block_Catalog_Bestseller</catalog_bestseller>
<catalog_bestsellerweekly>Simplicissimus_Rss_Block_Catalog_Bestsellerweekly</catalog_bestsellerweekly>
<catalog_bestsellermonthly>Simplicissimus_Rss_Block_Catalog_Bestsellermonthly</catalog_bestsellermonthly>
<catalog_bestsellernarcissus>Simplicissimus_Rss_Block_Catalog_Bestsellernarcissus</catalog_bestsellernarcissus>
<catalog_worstseller>Simplicissimus_Rss_Block_Catalog_Worstseller</catalog_worstseller>
</rewrite>
</rss>
</blocks>
</global>
<frontend>
<routers>
<rss>
<use>standard</use>
<args>
<modules>
<Simplicissimus_Rss before="Mage_Rss">Simplicissimus_Rss</Simplicissimus_Rss>
</modules>
</args>
</rss>
</routers>
</frontend>
</config>

Now let’s go create the controller for new RSS urls, create a file called controllers/CatalogController.php

<?php
// Controllers are not autoloaded so we will have to do it manually:
require_once 'Mage/Rss/controllers/CatalogController.php';
class Simplicissimus_Rss_CatalogController extends Mage_Rss_CatalogController
{
public function bestsellerAction()
{
$this->checkFeedEnable('bestseller');
$this->loadLayout(false);
$this->renderLayout();
}

public function bestsellerweeklyAction()
{
$this->checkFeedEnable('bestsellerweekly');
$this->loadLayout(false);
$this->renderLayout();
}

public function bestsellermonthlyAction()
{
$this->checkFeedEnable('bestsellermonthly');
$this->loadLayout(false);
$this->renderLayout();
}

public function bestsellernarcissusAction()
{
$this->checkFeedEnable('bestsellernarcissus');
$this->loadLayout(false);
$this->renderLayout();
}

public function worstsellerAction()
{
$this->checkFeedEnable('worstseller');
$this->loadLayout(false);
$this->renderLayout();
}
}

Now we need blocks, first of all create a file Block/List.php:

<?php
class Simplicissimus_Rss_Block_List extends Mage_Rss_Block_List
{

public function getRssMiscFeeds()
{
$this->resetRssFeed();
//$this->NewProductRssFeed();
//$this->SpecialProductRssFeed();
$this->SalesRuleProductRssFeed();

// SBF
$this->BestsellerRssFeed();
$this->BestsellerWeeklyRssFeed();
$this->BestsellerMonthlyRssFeed();
$this->BestsellerNarcissusRssFeed();
$this->WorstsellerRssFeed();

return $this->getRssFeeds();
}

public function BestsellerRssFeed()
{
$path = self::XML_PATH_RSS_METHODS.'/catalog/bestseller';
if((bool)Mage::getStoreConfig($path)){
$this->addRssFeed($path, $this->__('Ebook Bestseller (All time)'));
}
}

public function BestsellerWeeklyRssFeed()
{
$path = self::XML_PATH_RSS_METHODS.'/catalog/bestsellerweekly';
if((bool)Mage::getStoreConfig($path)){
$this->addRssFeed($path, $this->__('Ebook Bestseller (Ultima settimana)'));
}
}

public function BestsellerMonthlyRssFeed()
{
$path = self::XML_PATH_RSS_METHODS.'/catalog/bestsellermonthly';
if((bool)Mage::getStoreConfig($path)){
$this->addRssFeed($path, $this->__('Ebook Bestseller (Ultimo mese)'));
}
}

public function BestsellerNarcissusRssFeed()
{
$path = self::XML_PATH_RSS_METHODS.'/catalog/bestsellernarcissus';
if((bool)Mage::getStoreConfig($path)){
$this->addRssFeed($path, $this->__('Ebook Bestseller (Narcissus Self Published)'));
}
}

public function WorstsellerRssFeed()
{
$path = self::XML_PATH_RSS_METHODS.'/catalog/worstseller';
if((bool)Mage::getStoreConfig($path)){
$this->addRssFeed($path, $this->__('Ebook meno venduti'));
}
}

}

Well done, now we need to create one block file for each new RSS Feed we wanna publish, this file will be the one with the collection inside. Here I put only one of this for example you should need to complete the others or to remove from the other files:

<?php
class Simplicissimus_Rss_Block_Catalog_Bestseller extends Mage_Rss_Block_Abstract
{

/**
* Cache tag constant for feed reviews
*
* @var string
*/
const CACHE_TAG = 'block_html_rss_catalog_bestseller';

protected function _construct()
{
$this->setCacheTags(array(self::CACHE_TAG));
/*
* setting cache to save the rss for 10 minutes
*/
$this->setCacheKey('rss_catalog_bestseller');
$this->setCacheLifetime(600);
}

protected function _toHtml()
{
$newurl = Mage::getUrl('rss/catalog/bestseller');
$title = Mage::helper('rss')->__('Ebook Bestseller (All time)');

$rssObj = Mage::getModel('rss/rss');
$data = array('title' => $title,
'description' => $title,
'link'        => $newurl,
'charset'     => 'UTF-8',
);
$rssObj->_addHeader($data);

$_productCollection = Mage::getResourceModel('reports/product_collection')
->addAttributeToSelect('*')
->addOrderedQty()
->addFieldToFilter('type_id',  array('like'=>'downloadable'))
->addAttributeToFilter('status', 1)
->setOrder('ordered_qty', 'desc')
->setCurPage(1)
->setPageSize(20);

if ($_productCollection) {
$args = array('rssObj' => $rssObj);
foreach ($_productCollection as $_product) {
$args['product'] = $_product;
$this->addBestsellerXmlCallback($args);
}
}

return $rssObj->createRssXml();
}

public function addBestsellerXmlCallback($args)
{
$product = Mage::getModel('catalog/product')->load($args['product']['entity_id']);

Mage::dispatchEvent('rss_catalog_category_xml_callback', $args);

if ( $product->getTypeId() == "downloadable" )
$extendedDescr = "<p><strong>Autore: </strong>" . $product->getStealth_authors() . "<br /><strong>Editore: </strong>" . $product->getStealth_publisher() . "<br /><strong>Protezione: </strong>" . $product->getStealth_drm();
else
$extendedDescr = "<p>" . $product->getShortDescription() . "</p>";

//Mage::log($product->getData());

$description = '<table><tr>'
. '<td><a href="'.$product->getProductUrl().'"><img src="'
. $this->helper('catalog/image')->init($product, 'thumbnail')->resize(75, 75)
. '" border="0" align="left" height="75" width="75"></a></td>'
. '<td  style="text-decoration:none;">' . $extendedDescr;

$description .= '<p>' . Mage::app()->getLocale()->currency(Mage::app()->getStore()->
getCurrentCurrencyCode())->getSymbol() . " " . $this->helper('tax')->getPrice($product, $product->getFinalPrice(), true) . '</p>';

$description .= '</td></tr></table>';
$rssObj = $args['rssObj'];
$data = array(
'title'         => $product->getName(),
'link'          => $product->getProductUrl(),
'description'   => $description,
);

$rssObj->_addEntry($data);
}
}

You are almost done, now to display your new RSS custom feeds on the RSS page on your Magento (http://<magento_root>/rss) you only need to add them to the DB, simply add them to the table “core_config_data”:

• Scope: default
• Scope_id: 0
• path: rss/catalog/bestseller
• value: 1

You are done! Hope you find this guide useful.

Hope you enjoy it!

note:- the above code will only return array of most viewed products, just manupilate array in your design.

Step1: Open lib/zend/locale/data/en.xml

Step2: Locate territories tag in this file

Step3: copy one of territory tags for the syntax and paste it within the territories tag

Step4: hard part here is to add country code in this file as might not be able to find a unique one, so it’s upto you.

Step5: Save this file

Step6: Open table name directory_country

Step7: It has predefined syntax follow then same and create a new row and enter the same country code as entered in the en.xml file in 3 columns.

Step7: Refresh the site’s cache.

Step8: Admin > Configuration > General this new country should be selected in list of allowed countries.

Sometime we need to display webstore categories with there images on homepage, its very simple to do it
just create a page call it hopepage.phtml then go to magento backend and call cms block.
Paste the code below to your homepage.phtml file.

<div class="top-home-category">

    <?php
    $limit = 0;
    $_helper    = $this->helper('catalog/output');
    foreach ($this->getStoreCategories() as $_category):

        if($_category->getIsActive()):

            $cur_category = Mage::getModel('catalog/category')->load($_category->getId());

            if ($_imgUrl = $cur_category->getImageUrl()){

                $_imgHtml = '<img src="'.$_imgUrl.'" alt="'.$this->htmlEscape($cur_category->getName()).'" title="'.$this->htmlEscape($cur_category->getName()).'"  width="105px" />';
                $_imgHtml = $_helper->categoryAttribute($cur_category, $_imgHtml, 'image');
            } ?>
             <div class="home-category">
                <div class="linkimage">
                    <a href="<?php echo $this->getCategoryUrl($cur_category) ?>" style="border:none">
                    <?php echo $_imgHtml; ?>
                    </a>
                </div>
                <div class="category-link-container">

                       <?php echo $_helper->categoryAttribute($cur_category, $cur_category->getName(), 'name') ?>
                </a>
                </div>
            </div>

       <?php
           $limit+=1;
        endif;

        if ($limit==8):
            break;
        endif;

    endforeach;
?>
