How can I get a collection with all payment methods?

Question

I need to get a collection of all payment methods and list the quantity of orders on each of them, how can I do that programmatically?

Answer 1

You can make the array to collection in the following way:

$allActivePaymentMethods = Mage::getModel('payment/config')->getActiveMethods();
$collection = new Varien_Data_Collection();
foreach($allActivePaymentMethods as $row){
   $data=array('id'=>$row->getId(),'store'=>$row->getStore());
   $rowObj = new Varien_Object();
   $rowObj->setData($data);
   $collection->addItem($rowObj);
}

//now you can get the data using collection way
foreach($collection as $_data){
  print_r($_data->getData());
}

Answer 2

These are class methods app/code/core/Mage/Payment/Model/Config.php

To get a list with all payments active and inactive:

$allAvailablePaymentMethods = Mage::getModel('payment/config')->getAllMethods();

To get a list with all active payment methods:

$allActivePaymentMethods = Mage::getModel('payment/config')->getActiveMethods();

To get a list with all credit cards that Magento supports:

$allCcTypes = Mage::getModel('payment/config')->getCcTypes();
