Set Product Special Rates in Magento

Collected from a blog:

Using this code we can set special price timeline for specific products <?php // Start and End Dates must be in MySQL DB Format $startDate = '2012-01-01'; $endDate = '2012-01-03'; // Creates the Product object, whose Special Dates are going to be changed $product = new Mage_Catalog_Model_Product(); $product->load(YOUR_REQUIRED_PRODUCT_ID); // Sets the Start Date $product->setSpecialFromDate($startDate); $product->setSpecialFromDateIsFormated(true); // Sets the End Date $product->setSpecialToDate($endDate); $product->setSpecialToDateIsFormated(true); ?>
