How to Add Additional Options in Magento

Similar to my solution to add additional options in Magento 2, I have come up with the code for Magento 1 in this post.

The Magento 1 store, owing to the limitations of the platform, may require customization to offer excellent features. Hence, the method to add additional options in Magento!

We know that making changes in the core functionalities is not a good practice. Therefore follow the below method to custom develop features that allow collecting customer details, implement out-of-box functionalities and improve the shopping experience!

You can dynamically add options based on specific products without adding them from the backend using this method!

Steps to Add Additional Options in Magento:

1. Create config.xml file at app/code/local/Vendor/Extension/etc/ folder
   
   <?xml version="1.0" encoding="UTF-8"?> <config>     <modules>         <Vendor_Extension>             <version>1.0.0</version>         </Vendor_Extension>     </modules>     <global>         <models>             <extension>                 <class>Vendor_Extension_Model</class>             </extension>         </models>         <events>             <checkout_cart_product_add_after>                 <observers>                     <Vendor_Extension_Model_Observer>                         <type>singleton</type>                         <class>Vendor_Extension_Model_Observer</class>                         <method>checkout_cart_product_add_after</method>                     </Vendor_Extension_Model_Observer>                 </observers>             </checkout_cart_product_add_after>             <sales_model_service_quote_submit_before>                 <observers>                     <Vendor_Extension_Model_Observer_Set_Order>                         <type>singleton</type>                         <class>Vendor_Extension_Model_Observer</class>                         <method>setAdditionalDataToOrder</method>                     </Vendor_Extension_Model_Observer_Set_Order>                 </observers>             </sales_model_service_quote_submit_before>         </events>     </global> </config>

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

   <?xml version="1.0" encoding="UTF-8"?> <config>     <modules>         <Vendor_Extension>             <version>1.0.0</version>         </Vendor_Extension>     </modules>     <global>         <models>             <extension>                 <class>Vendor_Extension_Model</class>             </extension>         </models>         <events>             <checkout_cart_product_add_after>                 <observers>                     <Vendor_Extension_Model_Observer>                         <type>singleton</type>                         <class>Vendor_Extension_Model_Observer</class>                         <method>checkout_cart_product_add_after</method>                     </Vendor_Extension_Model_Observer>                 </observers>             </checkout_cart_product_add_after>               <sales_model_service_quote_submit_before>                 <observers>                     <Vendor_Extension_Model_Observer_Set_Order>                         <type>singleton</type>                         <class>Vendor_Extension_Model_Observer</class>                         <method>setAdditionalDataToOrder</method>                     </Vendor_Extension_Model_Observer_Set_Order>                 </observers>             </sales_model_service_quote_submit_before>         </events>     </global> </config>

    
2. Create Observer.php file at app/code/local/Vendor/Extension/Model/ folder
   
   <?php class Vendor_Extension_Model_Observer {     public function checkout_cart_product_add_after($observer)     {         $event = $observer->getEvent();         $quoteItem = $event->getQuoteItem();         $messageOption = array(             'label' => 'Message',             'option_value' => 'Custom Value',             'value' => 'Custom Value',             'print_value' => 'Custom Value',         );         $value = array('message' => $messageOption);         $value = serialize($value);         $quoteItem->addOption(array('code' => 'additional_options', 'product_id' => $quoteItem->getProductId(), 'value' => $value));     }     public function setAdditionalDataToOrder($observer)     {         try {             $quote = $observer->getEvent()->getQuote();             $order = $observer->getEvent()->getOrder();             $quoteItems = [];             foreach ($quote->getAllVisibleItems() as $quoteItem) {                 $quoteItems[$quoteItem->getId()] = $quoteItem;             }             foreach ($order->getAllVisibleItems() as $orderItem) {                 $quoteItemId = $orderItem->getQuoteItemId();                 $quoteItem = $quoteItems[$quoteItemId];                 $additionalOptions = $quoteItem->getOptionByCode('additional_options');                 if (count($additionalOptions) > 0) {                     $options = $orderItem->getProductOptions();                     $options['additional_options'] = unserialize($additionalOptions->getValue());                     $orderItem->setProductOptions($options);                 }             }         } catch (\Exception $e) {             Mage::log($e->getMessage());         }     } }

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51

   <?php   class Vendor_Extension_Model_Observer {     public function checkout_cart_product_add_after($observer)     {         $event = $observer->getEvent();         $quoteItem = $event->getQuoteItem();           $messageOption = array(             'label' => 'Message',             'option_value' => 'Custom Value',             'value' => 'Custom Value',             'print_value' => 'Custom Value',         );           $value = array('message' => $messageOption);         $value = serialize($value);         $quoteItem->addOption(array('code' => 'additional_options', 'product_id' => $quoteItem->getProductId(), 'value' => $value));     }       public function setAdditionalDataToOrder($observer)     {         try {             $quote = $observer->getEvent()->getQuote();             $order = $observer->getEvent()->getOrder();             $quoteItems = [];               foreach ($quote->getAllVisibleItems() as $quoteItem) {                 $quoteItems[$quoteItem->getId()] = $quoteItem;             }               foreach ($order->getAllVisibleItems() as $orderItem) {                   $quoteItemId = $orderItem->getQuoteItemId();                 $quoteItem = $quoteItems[$quoteItemId];                   $additionalOptions = $quoteItem->getOptionByCode('additional_options');                   if (count($additionalOptions) > 0) {                     $options = $orderItem->getProductOptions();                     $options['additional_options'] = unserialize($additionalOptions->getValue());                     $orderItem->setProductOptions($options);                 }               }         } catch (\Exception $e) {             Mage::log($e->getMessage());         }     } }

That’s it.
