====== Adding a new product ======


Here is how you can add a product using Magento backend.

  //create a new product
  try {
    $newProduct = Mage::getModel('catalog/product')
      ->setStoreId('default')
      ->setCategoryIds('4')
      ->setAttributeSetId(41)
      ->setPrice(15.49)
      ->setSku('4you')
      ->setName('4You T Shirt')
      ->setManufacturer(20)
      ->save(); 
      
    echo 'OK Product ID: '.$newProduct->getId();
  }
  catch (Mage_Core_Exception $e) {
    echo $e->getMessage();
  }
  catch (Exception $e) {
    echo $e;
  }

You can set any other attribute by using universal setter function setData($attribute_code, $value) or for example for shirt size: setShirtSize($value).
Varian object translates it automatically into setData('shirt_size', $value).

If you want to update existing product, call $newProduct->load($id) before setting any attributes.
