I need a script that will check all magento products and set them to instock if the qty is greater than 0.

The plan is to run this as a scheduled cronjob so that it will be checking for any products that have their stock value incorrectly set.

My code is rather crude so far but here is what i have come up with:

<?php PHP_SAPI == 'cli' or die;
error_reporting(E_ALL | E_STRICT);
require_once '../app/Mage.php';

$product = Mage::getModel('catalog/product')->load($product_id);
$stock_item = $product->getStockItem();

     if ($stock_item->getQty() < 0){

Unfortunately when i run this nothing changes in the backend and no products are set to instock as they should.

Perhaps somebody could point to where i'm going wrong or a better solution?

  • if ($stock_item->getQty() > 0) and check the manage_stock to 1.

Also, you can try this way. Hope it works.

$_product = Mage::getModel ( 'catalog/product' )->load($product_id);
$stockItem =    Mage::getModel('cataloginventory/stock_item')->loadByProduct($_product->getId());
        if($stockItem->getQty() > 0) {
           $stockItem->setData('is_in_stock', 1);
           $stockItem->setData('manage_stock', 1);                  
        } else {
           $stockItem->setData('is_in_stock', 0);
  • Thanks @albeis i've tried your code above but for some reason i'm getting integrity contstraint errors now.
