Magento – How to set enable qty increments and set the qty increment in php

magento-1.7magento-1.8

I have a large list of products that for each I have to enable qty_increments and set the qty_ increment to a specific value for that product.

I am not sure how to do that in php.

I know how to get and save the product just not how do enable and set the increments

my input is:

sku qty_increment
sku qty_increment ….

Thanks

   $product = Mage::getModel('catalog/product')->loadByAttribute('sku',$sku);
   $productId = $product->getId();
   $stockItem = Mage::getModel('cataloginventory/stock_item')->loadByProduct($product->getId());
   $stockItemId = $stockItem->getId(); // in case you need it

   $stockItem->setData('use_config_qty_increments', false);
   $stockItem->setData('use_config_enable_qty_inc', false);
   $stockItem->setData('use_config_enable_qty_increments', false);

   $stockItem->setData('enable_qty_increments', true);
   $stockItem->setData('qty_increments', $newIncrement);

I am not sure if I need all that, or if it can be shortened, but it works for me as is. I am not showing the error checking and handling.

Magento 1.7 – How to Set Block Actions in PHP

Actions in layout xml configs are just a block method call. So if you see construction like

<block type     = "checkout/cart_sidebar" 
       name     = "cart_sidebar" 
       as       = "cartExplorer" 
       template = "checkout/cart/sidebar.phtml" 
       before   = "-">
<action method="addItemRender">
    <type>configurable</type>
    <block>checkout/cart_item_renderer_configurable</block>
    <template>checkout/cart/sidebar/default.phtml</template>
</action>

That is equivalent to

$this->getLayout()
     ->createBlock('checkout/cart_sidebar', 'cart_sidebar')
     ->setTemplate('checkout/cart/sidebar.phtml');
     ->addItemRender(
         'configurable', 
         'checkout/cart_item_renderer_configurable',
         'checkout/cart/sidebar/default.phtml'
     )

Or if block cart_sidebar was already created in layout xml

$this->getLayout()
     ->getBlock('cart_sidebar')
     ->addItemRender(
         'configurable', 
         'checkout/cart_item_renderer_configurable',
         'checkout/cart/sidebar/default.phtml'
     )

Magento – Product QTY Increment Magento 1.8

Peter, you're trying to use wrong functionality. Quantity increments are meant to be used in cases where you absolutely have to sell something that can't be sold separately, such as six beers in a special package, as doing otherwise decreases its value. This means that you can only choose following quantities: 6, 12, 18, 24 and so on. What YOU want to do is to use bundles: create a new Bundle Product, add associated products as REQUIRED check-box (quantity 100). This way you can choose put one bundle to shopping cart while decreasing stock status of original product by 100 (or in my case by 6). If you need more information search the internet for how to create bundled products, there're TONS of excellent tutorials for scores of languages.
