Question

I need to customize other’s code,

so I found they used

     Mage::getSingleton('core/session')->getMyCustomBlockInfo();

in Order.php file for custom order email

so I can’t find this function getMyCustomBlockInfo();

Can anyone tell me where this function reside?

Thanks

Answer 1

example :

Mage::getModel('catalog/product'); //or
Mage::getSingleton('catalog/product');

the code must be in ‘../app/core/Mage/Catalog/Model/Product.php‘ file

then

Mage::getSingleton('core/session');

the code must be in ‘../app/core/Mage/Core/Model/Session.php‘ file

because the class Mage_Core_Model_Session‘s parent::parent is Varien_Object, then you can do all magic functions and you can ->getData() to see the Data inside.

Mage::getSingleton('core/session')->getData();

on your problem when go call ->getData() you can see data : [my_custom_block_info]

you can set it with call

Mage::getSingleton('core/session')->setMyCustomBlockInfo('what');

Mage::getSingleton('core/session')->getMyCustomBlockInfo();
// will return 'what'
