Hi Guys,
One day i need to pull the country collection of selected in the Allow country list in under general tab for default configuration store scope but not getting any clue for this. After 4-5 hours review the code and database table finally i success to do this. I don't know this is right way or not but it works . it may helpsome who want to such a things.......
////////////////////////////////////
$rr= Mage::getConfig()->getNode('general/country/allow','default');
$rr=explode(',',$rr);
$options =Mage::getModel('directory/country')->getCollection()
->addFieldToFilter('country_id',array('in'=>$rr))
->load()
->toOptionArray();
///////////////////////////////////////
This line $rr= Mage::getConfig()->getNode('general/country/allow','default'); help to choose the country id string for default scope value. And then we can get the selected country's list.
enjoy!!!!!
