If you're working with Magento often you'll find sometimes you need to use Magento functions and classes outside of the Magento platform. This can be easily achieved with the following lines of code. ? 1 2 3 4 5 6 7 8 9 10 require_once('app/Mage.php'); //Path to Magento umask(0); Mage::app();   // Now you can r......

Sometimes a client asks to be able to manage certain areas of their Magento ecommerce website that would usually require access to template files. While this is okay, most clients consider HTML a foreign language and would probably do more harm than good. To remedy this, a lot of developers would consider creating a custom module. While this isn't bad, sometimes it can require too much work if the client only wants to change one line of text! A much easier and quicker solution is to use a static block. Static Blocks can be included into your design in three main ways: Inside a ......

addAttributeToFilter is a function that can be called on a product collection in Magento. In short, it adds a condition to the WHERE part of the MySQL query used to extract a product collection from the database. ? 1 2 3 4 $_products = Mage::getModel('catalog/product')->getCollection()    ->addAttributeToSelect(array('name', 'product_url', 'small_image'))    ->addAttributeToF......

This error occurs when the user gets to the final step in the Magento Onepage checkout: the order review. When they click the submit button the page loads for a few seconds and then a Javascript alert box is displayed with the message 'undefined'. Not only does this destroy the trust a customer has in your website, it actually stops them from completing the purchase. This means you are losing money and customers! Unfortunately there is no quick generic fix for this but hopefully, by explaining the cause and a way to identify the error, you will be able to overcome this on your own.......

What is Cron? To quote Wikipedia, 'cron is a time-based job scheduler in Unix-like operating systems.' It functions similarly to Windows Task Scheduler in that it allows you to specify actions to be ran after a certain interval. This can be useful for running daily backups or deleting your logs at the end of every month. Where is Cron Used in Magento? By default, cron is used in Magento for various things such as keeping your catalog indexes up to date and refreshing catalog price rules. Cron jobs can also be set up for custom modules, which we will cover shortly. D......

While Javascript form validation shouldn't be your only form of defense with regards to user input, it definitely improves the usability and efficiency of a site. It can also give your site a web 2.0 feel - which users seem to love. Javascript Validation in Magento By default Magento uses a file called form.js (js/varien/form.js) to provide abstract Javascript functions for forms. The most useful application of this class - in my opinion - is the form validation. To achieve this validation, form.js uses the Validation class which is part of the Prototype Javascript library. It ......

There are many ways to mass update product attributes in Magento, each well suited to a different purpose. Magento's built-in mass product attribute updater is great if you want to modify a selection of products or the new attribute value is the same for all products you want to edit. Alternatively, if you wish to alter the attributes in more dynamic ways, updating them programmatic ally via PHP is probably a better way. The downside to both of these methods is speed, with each product update taking a few seconds to complete. While this time can be dramatically reduced by disabling ind......

The Entity, Attribute and Value (EAV) database architecture is at first, extremely difficult to grasp. Combine this with the lack of documentation on EAV and you find that most people don't truly appreciate just how good EAV is and more importantly, how well suited it is to Magento. In this article I will attempt to shed some light on EAV in the hopes of helping you understand how it works, why it works and how this knowledge can benefit you as a Magento developer. To better understand this article, I recommend opening up a development Magento database using a tool such as phpMyAdmin. ......
