Sometimes you’d just like to add an unpaid invoice to Magento order without it being set to paid status (Cash on Delivery anyone?). Once again I found a tutorial on Inchoo which described the biggest part of generating an invoice programmatically for an order, but it was always set to paid status. Well, I found the solution:

It’s mostly the line $invoice->setState() which I changed. And I switched to offline capturing, all other options are documented.

I was calling this function from an event observer but you could also just load an order using:

Like the title says, the cron was broken when using Aoe_Scheduler so I decided to write my own little script from Xtento’s own code.

I put this file in the shell directory and actually just call it with a crontab at 00:00 every day:

The contents of the export function could also just be placed in the contruct, and it might not necessarily need the secureArea and setCurrentStore but it’s the contstruct I always use and it works 😉

Magento Configurable Option UpdateFor a project I had to figure out how to update options of a configurable product in the Magento Cart.

Considering the code from the famous Inchoo post from 2009 does not work anymore in Magento 1.8+ and I managed to get it working I decided to document the function for my fellow Magento developers out there on the interwebs. The code from the Inchoo post does change a few parts of the quote item but misses a few vital parts like changing the SKU. So on the frontend you might think it has properly changed the product, it will even show up fine in your cart, but once you checkout it will still use the old product! Turns out there’s a cart function called updateItem which can not only change the quantity but also the selected option of configurable.

Hope you’re all happy with this one, it took one of our developers more than 2 weeks to not get it working and I managed it in a day, once again. Mind you, a day is still frustratingly long for me, hence the post because everyone should be able to save that amount of time while working in a project..

The function I wrote to update options of a configurable product in the Magento Cart

To update the flavor of a configurable project we currently use a url like this:
http://somedomain.com/modulename/cart/updateajaxcart?productId=7260&itemId=3004&productQty=1&supperAttributeId=175&childId=237

Some explanation of the various variables you’re supposed to pass to the function:

  • $superAttributeId is the id of the attribute, in our case flavor which has id 175.
  • $childId is the id of the selected option of the attribute
  • $itemId is the id of the item in the cart
  • $productId is the id of the actual product, in this case the configurable
  • $refresh: if set will force the current page to refresh after updating the cart (handy for cart page since you want to not only refresh the ajax cart but also the whole cart page)

I cleaned up the code while writing the post so an error might have slipped in during the process, if you find anything wrong with it please don’t hesitate to comment and I will fix the code
