Catalog price rules not applied when creating order from Magento admin

Magento BugEven though I'm in love with the platform, as it turns out, I tend to blog about Magento bugs quite often. I like to believe this is a good thing, because besides helping other Magento developers, finding and fixing bugs makes our favorite ecommerce platform better. It has nothing to do with frustration couple of days debugging session can cause, I ensure you. In this article I'm about to explain and provide workaround for bug affecting all Magento versions (including latest Magento CE 1.9.0.1 at the time of writing), one that's causing catalog price rules not being applied to final price and totals not getting calculated correctly when creating orders from Magento admin, all this under specific and hard to reproduce circumstances. Honestly, this is probably the ugliest bug I've ever seen in my coding career, largely due to fact that client's bug report is usually that catalog price rules prices revert when creating orders from Magento admin, but only sometimes and without any pattern.

Programmatically add new order state and status in Magento

Magento Orders Menu ItemRecently my task was to allow client to have different "type" of order in Magento. Requirement was that these orders need to have their own grid in Magento admin, and also that they need to be processed somewhat differently than regular orders. I have solved this task by adding new order states and statuses to be used only for this type of orders. To support this design it was also required to create new payment method so that orders of this type can be initiated into new order state automatically after being placed using this payment method. In this article I'm bringing you some code snippets and notes on how to implement this kind of solution.

Bash script to generate list of events for Magento installation

Magento Logo When developing for Magento, there are two ways to modify code provided by other modules - doing rewrites and observing events. If appropriate event is available for observing, it is preferred to use second method to alter other module's behavior. More precisely it is preferred to observe event of your interest, and when this event occurs, to trigger execution of your own code. But how are you supposed to know the list of events that are available for observing on your Magento installation? If you're interested to find out answer to this question, take the red pill, and I'll show you how deep the rabbit-hole goes.

Install Magento on Ubuntu and fix PHP Extensions "0" must be loaded error with PHP 5.4

Magento LogoEvent though I follow MVC pattern in many of my web related projects, like every PHP web developer I came to the point when I have to dive into some well established MVC PHP framework. This is something backend developer must do if he wants to stop being a lone wolf and start working inside a team of developers. Web frameworks of my choice are fast Codeigniter and powerful Zend Framework. Getting to know about Codeigniter wasn't hard, but mastering Zend is still work in progress especially since Zend Framework 2 has been recently released. Talking about Zend, recently I got interested in getting to know about open source eCommerce solutions and I choose to get acquainted with Zend based Magento. In this article I'll show you how to install Magento on a Debian based distributions like Ubuntu and provide workaround for the PHP Extensions "0" must be loaded error thrown by Magento installer running on PHP 5.4.
