Magento project I'm currently in charge for has had the catalog price rules not sticking issue for some time now. This issue has been first reported as catalog price rules being unapplied on their own without any obvious pattern. Since, due to nature of it's catalog, catalog price rules are very backbone of the store in question, situation where prices change on their own was certainly problematic. Even though this Magento project wasn't of this edition or version, it was using Mage_Catalogrule module that was shipped with Magento Community Edition 184.108.40.206. Later research revealed that this issue has been fixed in Magento CE 220.127.116.11 (and all Magento editions and version derived from it), but immediate upgrade wasn't viable alternative at the time because I didn't know what causes this issue and has it been fixed upstream. Allow me to share debug path I had to take to get to the bottom of this.Continue reading
Recently I had to to publish an article in a way that common site visitors aren't aware of it's existence. Basically this article had to be excluded from all WordPress loops and visible only when accessed directly. General idea of solution presented in this article is to use pre_get_posts hook to alter WP_Query. Goal is excluding hidden post on frontend, area that isn't single post and when area is single post other than hidden post it self. Now allow me to share code snippet that can be used for this purpose.Continue reading
Magento application programming interface allows third party applications to programatically interact with Magento instance. Magento supports two API standards, SOAP/XML-RPC and REST. Distinctive characteristics of SOAP (Simple Object Access Protocol) is that it uses XML as it's message format, and when used over HTTP it delivers data trough POST request method. My personal preference lies with REST APIs, but in my experience with version 2 of Magento SOAP API, I can freely say that it's one of the most enjoyable SOAP APIs I had privilege of working with. Only thing that bothers me is that Magento currently doesn't provide feature for allowing developers to peek inside SOAP envelope when something isn't working as it should. Essentially it isn't possible to easily debug SOAP API calls Magento receives. In this article I'm bringing Magento extension allowing you to capture SOAP API requests and log them into file.Continue reading
Recently 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.Continue reading
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.Continue reading

In my last article on this topic I brought a brief introduction into installing XMPP server Prosody on you Debian/Ubuntu based server. In this follow-up article I'll show you how to configure Bidirectional-streams Over Synchronous HTTP (BOSH) XMPP extension on Prosody XMPP server with the intention of creating XMPP powered web applications.
Very often when developing for web inside your LAMP environment you need to send emails using PHP. Configuring fully fledged email server on your Linux box is an option, although one I don't recommend. Life's too short to spend it configuring many mail transport agent of your choice configuration files just to check is your PHP application sending emails or not. In this article I'll show you how make your development environment capable of testing email sending features of your PHP applications in almost no time.Continue reading
Some of you are probably wondering why would you want to spend your time fiddling with default desktop environment settings customization, when you can easily customize everything to your liking inside you own user account? Most probably you'd want to do this when you're re-mastering your favorite Linux distribution using tools like OS4 system imager (fork of the now discontinued Remastersys) or Relinux. In this article I'll show you how to handle this task elegantly using GSettings vendor overrides.Continue reading
In my first article for Inchoo.net last week I've described how to easily manage LAMP name based virtual hosts using bash script that simplifies virtual hosts management on a Debian based Linux operating systems. While I was coding the script in question, I have assumed that most people develop from default document root /var/www and using Apache's mod_php5. In this article I'll show you how to setup your LAMP environment to develop in your home directory using another Apache module suPHP.Continue reading
