Avoid merging old cart items in customer session magento

-
In this post we will see how to avoid merging old cart items to the current checkout session.

Scenario:

  • It will be happen when we login to store and adds some products into cart and leaves store without purchasing.
  • Then coming back to the store after sometime and adds some product into cart without login and proceeds to checkout.
  • In checkout page we will be requested to login, after login we can see some additional products are added into the cart which we are added in previous session.
  • In this case what we have to do is we need to clear old cart items( It was requested by one of my client ) and allow customers to show with the current session items.
Below i have given the codes used to clear old cart items. And also attached the file. File: app/etc/modules/Ws_Clearoldcartproducts.xml 
    
    
        
            
                true
                local
File: app/code/local/Ws/Clearoldcartproducts/etc/config.xml In below code we are using sales_quote_merge_before observer to clear old items. To know about observer go through this link. 
    
    
        
            
                1.0.0
            
        
        
            
                
                    
                        
                            singleton
                            Ws_Clearoldcartproducts_Model_Observer
                            loadCustomerQuote
File: app/code/local/Ws/Clearoldcartproducts/Model/Observer.php We have declared our observer class and action names in above xml file. Below code is where our magic works! 
    setStoreId(Mage::app()->getStore()->getId())
                    ->loadByCustomer(Mage::getSingleton('customer/session')->getCustomerId());

            if ($customerQuote->getId() &
            &
            $this->getQuoteId() != $customerQuote->getId()) {
                // Removing old cart items of the customer.
                foreach ($customerQuote->getAllItems() as $item) {
                    $item->isDeleted(true);
                    if ($item->getHasChildren()) {
                        foreach ($item->getChildren() as $child) {
                            $child->isDeleted(true);
                        }
                    }
                }
                $customerQuote->collectTotals()->save();
            } else {

                $this->getQuote()->getBillingAddress();
                $this->getQuote()->getShippingAddress();
                $this->getQuote()->setCustomer(Mage::getSingleton('customer/session')->getCustomer())
                        ->setTotalsCollectedFlag(false)
                        ->collectTotals()
                        ->save();
            }
            return $this;
        }

    }
    ?>
What we have done in above code is we have override the Mage_Checkout_Model_Session::loadCustomerQuote() action to avoid merging of old cart items!. Instead of merging the product we have deleted it! That's what we done! Please post your feedback's Thanks :)

Convert long url to short url using tinyurl api

-
Tinyurl provides us a short and simple service to convert long URL to small(tiny) URL. We can send email without link breakage. Here is the tinyurl api to get shorten url. You can use any of the method. Method 1: Use file_get_contents to fetch tinyurl. echo file_get_contents('http://tinyurl.com/api-create.php?url=http://www.websnippetz.com'); file_get_contents is not working? If your are able to access php.ini file set allow_url_fopen = On or you can use the below method. Method 2: Use cURL (runs faster than file_get_contents) to fetch tinyurl. function get_tiny_url($url) { $url = "http://tinyurl.com/api-create.php?url={$url}"; $ch = curl_init(); $timeout = 5; curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout); $data = curl_exec($ch); curl_close($ch); return $data; } echo get_tiny_url('http://www.websnippetz.com');
