Programmatically added product has empty Quantity field and doesn't show up on the frontend [duplicate]

Question

I am trying to add a product to my Magento store programmatically. Basically I'm duplicating a template and editing it:

$storeId = Mage::app()->getStore()->getId(); // get store id
$product = Mage::getModel('catalog/product')->load(186);

$new = $product->duplicate();

$new->setSku(date('YmdHis'));
$new->setData("url_path", "$name.html");

$new->setEnableGooglecheckout(0);
$new->setIsImported(0);
$new->setLinksExist(false);
$new->setDescription($desc);
$new->setMetaKeyword($desc);
$new->setCustomLayoutUpdate(NULL);
$new->setName($name);
$new->setMetaTitle($desc);
$new->setMetaDescription($desc);
$new->setLinksTitle("Visitenkarten");
$new->setWebsiteIds(array(1));
$new->setData("links_exist", "1");

$new->setStockData(array(
                   'use_config_manage_stock' => 0,
                   'manage_stock'=>1, 
                   'min_sale_qty'=>1,
                   'max_sale_qty'=>2,
                   'is_in_stock' => 1,
                   'qty' => 999
               )
);

$new->setState(1);
$new->save();

In my admin panel, the new product does show up, but the "Quantity" is empty. When I edit the product in the admin panel and save it, a "0" shows up in the Quantity field.

Can anyone help me with this?

EDIT: The question my answer has been marked a duplicate of isn't describing the same error. The code in this question is already throwing an error on execution, but my code is just creating a product only showing up on the admin panel.

Answer 1

You need to create a new product, duplicate the data

$product = Mage::getModel('catalog/product')->load(186);
$new = $product->duplicate();

//Set all product data

$new->setData(.........);

Create a new stock item and set the data on that object

$stockItem = Mage::getModel('cataloginventory/stock_item');

$stockItem->setData(array(
                   'use_config_manage_stock' => 0,
                   'manage_stock'=>1, 
                   'min_sale_qty'=>1,
                   'max_sale_qty'=>2,
                   'is_in_stock' => 1,
                   'qty' => 999
               )
);
$stockItem->save();

Assign new stock item to product and save.

$new->setStockItem($stockItem);
$new->getResource()->save($new);

Inchoo has a blog article about this

<?php
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
$product = Mage::getModel('catalog/product');

//    ->setStoreId(1) //you can set data in store scope
