Magento block caching

Recently we were working on speeding up parts of client site which had usual problem of slow page loading caused by complicated configurable products. To solve the problem we were experimenting with extending core Magento caching capabilities.

Magento has built in predifined system of block output caching. Its block abstract has Zend_Cache caching capabilities that can be modified for your own needs. I’m showing here an example of caching whole product view block, however this is just a specific example of how things works, problems are different and requires different approach and solution.

I will start with some external reading and example itself. There is great article on Magento Wiki about this topic, along with category cache example on Magento forums.

Programatically create Magento blocks and inject them into layout

Imagine a scenario where you wish to simply create a view file like custom-note.phtml and show this view file on some new url inside the Magento store . One way to do this is to create a CMS page and call that block from within CMS page. But what if you wish to create and append this block to other areas of Magento layout that are inaccessible from CMS page interface form admin? What if I want to add new div element under the breadcrumbs and append new block under it?

magento philosophy is to create block class under the /Block folder of your module, to create xml layout file under the theme /layouts folder (or to modify existing layout file) and so on. Anyway you turn it around you either need to have Block file or add/modify at least the entry to the layout files.

All this is OK if you are working on your own store so you have full control over the code. However, what if you are developing a module that will be used on different Magento stores. My prime concern when building a module is to keep the number of necessary module files to a minimum.

This is my first post here and I’ll write about my first challenge regarding Magento since I came to work at Inchoo.

As title says I’ll show you how to implement simple random banner rotation functionality in Magento using static blocks.

First of all, upload images you want to use in “/skin/frontend/YOUR_INTERFACE/YOUR_THEME/images/

In admin panel add N static blocks (”CMS->Static Blocks->Add new block”)

For identifier field use something like this:

What’s in a block? – Some Magento “basics”

Many developers are familiar with the MVC (Model View Controller) design pattern that is seemingly ubiquitous throughout web frameworks. Looking through the code in Magento, however, we see many other components besides the M’s the V’s and the C’s.

Each module  (a “module” meaning the separate directories within the “app/code/core/Mage” directory that comprise of Magento’s different functional areas) contains the usual Controller and Model. You’ll see that within each module, there are no Views (more on this later). You’ll also see extra tidbits, such as “helper” , “etc” and “sql”. These are (and are not) standard within the Zend Framework context and will not be discussed in this article. In these modules are also the sort of files which we work with very often. The all powerful block! This article will attempt to (hopefully accurately) describe just what a Block is and how it’s used.

How to Add Dynamic Content to Magento Static Blocks and Pages?

Magento provides an easy way to create blocks of static content which, with a little Layout-XML-Fu, can be added to any page in Magento. Even better, these blocks can be added to any category page with no programming at all. This is great if you want to have a banner image with monthly specials and deals, or if you want to add a header image or descriptive text to a category.

Magento also makes it really easy to create static SEO landing pages. In just a few clicks you have a new static page, ready to lace with images and tasty keyword laden text, and to link to any product or category in the Store proper.
