How to get ordered qty of product in front-end?
No correct solution
Your question is a little unclear. This is how to get the quantity available for a product, which actually means the STOCK.
// get the quantity for a Mage_Catalog_Model_Product $product $productStockItem = $product->getStockItem(); $productStockItem->getQty();
If you want the number of sold items you'll have to select all your orders and search for products in there, and is a little more complicated. I dont think that the type of product and the display frontend or backend makes it different in any way.
