Filter Payment & Shipping Method on Checkout Page

To filter Payment Method Options  we can use observer, i assume you have knowledge of Magento module development, anyway let’s begin

1. on config.xml, register an event
2. ..... <events> <payment_method_is_active> <observers> <paymentfilter_payment_method_is_active> <type>singleton</type> <class>myfilter/observer</class> <method>paymentMethodIsActive</method> </paymentfilter_payment_method_is_active> </observers> </payment_method_is_active> </events> .....

   1 2 3 4 5 6 7 8 9 10 11 12 13

   ..... <events>   <payment_method_is_active>             <observers>                 <paymentfilter_payment_method_is_active>                     <type>singleton</type>                     <class>myfilter/observer</class>                     <method>paymentMethodIsActive</method>                 </paymentfilter_payment_method_is_active>             </observers>         </payment_method_is_active>   </events> .....

3. create observer file app/code/local/MyModule/MyFilter/Model/Observer.php
4. <?php class MyModule_MyFilter_Model_Observer { public function paymentMethodIsActive(Varien_Event_Observer $observer) { $event = $observer->getEvent(); $method = $event->getMethodInstance(); $result = $event->getResult(); /* remove COD payment */ if($method->getCode() == 'cashondelivery' ){ $result->isAvailable = false; }else{ $result->isAvailable = true; } } }

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

   <?php class MyModule_MyFilter_Model_Observer {     public function paymentMethodIsActive(Varien_Event_Observer $observer) {         $event           = $observer->getEvent();         $method          = $event->getMethodInstance();         $result          = $event->getResult();           /* remove COD payment */           if($method->getCode() == 'cashondelivery' ){                 $result->isAvailable = false;             }else{                 $result->isAvailable = true;             }         }              }

   
    

next to filter shipping methods you have to rewirite shipping model file

1. on config.xml file
2. ... <global> ... <models> <shipping> <rewrite> <shipping>MyModule_MyFilter_Model_Shipping</shipping> </rewrite> </shipping> </models> ... </global> ...

   1 2 3 4 5 6 7 8 9 10 11 12 13

   ... <global>     ...     <models>         <shipping>             <rewrite>                 <shipping>MyModule_MyFilter_Model_Shipping</shipping>             </rewrite>         </shipping>     </models>     ... </global> ...

3. create file app/code/local/MyModule/MyFilter/Model/Shipping.php
4. <?php class MyModule_MyFilter_Model_Shipping extends Mage_Shipping_Model_Shipping { public function collectCarrierRates($carrierCode, $request) { if (!$this->_checkCarrierAvailability($carrierCode, $request)) { return $this; } return parent::collectCarrierRates($carrierCode, $request); } protected function _checkCarrierAvailability($carrierCode, $request = null) { /* remove Free shipping */ if($carrierCode == 'freeshipping'){ return false; } }

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

   <?php class MyModule_MyFilter_Model_Shipping extends Mage_Shipping_Model_Shipping {     public function collectCarrierRates($carrierCode, $request)     {         if (!$this->_checkCarrierAvailability($carrierCode, $request)) {             return $this;         }         return parent::collectCarrierRates($carrierCode, $request);     }     protected function _checkCarrierAvailability($carrierCode, $request = null)     { /* remove Free shipping */ if($carrierCode == 'freeshipping'){                 return false;         }     }
