I am getting product collection from external php file like below-
<?php
$mageFilename = 'app/Mage.php';
require_once $mageFilename;
//Mage::setIsDeveloperMode(true);
//ini_set('display_errors', 1);
umask(0);
Mage::init('default');
Mage::app('default');
$productCollection=Mage::getModel('catalog/product')->load(169);
var_dump( $productCollection->getHidemrp());
Hidemrp is "yes/no" type custom attribute.
But I am not getting any value ? what is the problem.?
