An introduction to fetching content in eZ Publish 4 and eZ Publish 5

Fetching content in eZ Publish 4 (the "legacy" stack) and eZ Publish 5 (the "new" stack) follow many of the same principles, which is not surprising since the data layer is the same for both versions. You typically have a parent node or location and a set of filters. User permissions -- especially bypassing those permissions -- is often a consideration. In this post we'll explore how to fetch content in the legacy and new stack (as of eZ Publish 5.2).


Using VirtualBox to install and test eZ Publish 5

Using virtual machines when developing eZ Publish websites have been useful in 2 main ways (if not more): working in a different server environment than your current machine and standardizing the dev environment for a team of developers. At the moment, I have Ubuntu 13.10 installed as my main operating system, and from time to time I need to work with some older eZ Publish versions that require PHP versions older than Ubuntu 13.10's default; in fact, the oldest eZ Publish version that I can run out of the box on Ubuntu 13.10 is eZ Publish 4.7. I don't like the idea of installing another OS just to work with an older eZ Publish version; that requires creating another partition, configuring grub, and so on. Using virtual machines enables me to work within another OS inside my main OS. That way I can work on a standardized environment specific to each client, while continuing to use my favorite base OS and tools. In this tutorial, I will describe how to install and configure Oracle VirtualBox to create virtual machines that run eZ Publish.

Disqus comments

Integrating Disqus comments onto an eZ Publish website

Disqus is one of the most popular third-party commenting tools that can be integrated onto your website. There are a few special considerations when implementing Disqus onto a website where an article might have multiple locations and/or the article's URL might change. In this post, we'll walk you through a basic but robust implementation within an eZ Publish site.

This is somehow related to the events system :)

eZ Publish code-level events, aka ezpEvent

The eZ Publish events system, known otherwise as "ezpEvent" (the name of the PHP class), supports multiple extension points into the content management system and also enables you to define your own extension points. It was quietly introduced in eZ Publish 4.5.

CSM archive links

Archiving in eZ Publish: a case study

Mugo planned and implemented an article archiving solution for The Christian Science Monitor, an award-winning news website. The site has a large amount of content: visitors have access to articles starting from 1980. In total, the site has almost 800,000 content objects and the current setup serves up to 48 million page views per month.

Don't panic

Re-building a corrupt eZ Publish cluster table

We were called to investigate a clustered eZ Publish 4.5 (with eZ DFS) site where most of the images were suddenly missing. As we discovered, due to an erroneous MySQL command, the "ezdfsfile" table had been truncated. It was near the end of the day, and there were no viable database backups since the previous night. We either had to somehow rebuild the "ezdfsfile" table or ask many editors across different departments to re-do all their work from that day. It was a rather panicked situation.

How to use Composer to set up an eZ Publish install

Composer is a dependency management tool for PHP that eZ Publish 5 uses. The following is simple step-by-step how-to on using Composer to install eZ Publish (legacy) with additional extensions.

Multi-class attribute filter

Extended attribute filters: advanced content retrieval in eZ Publish

Retrieving content is one of the most common use cases when working with a content management system. eZ Publish provides a powerful way to retrieve content with its fetch functions. Although it provides a powerful framework for filtering and sorting the content based on a wide range of criteria, sometimes you need to extend the framework. Adding new filters to fetch functions is achieved by using extended attribute filters.


Using a preview siteaccess as an eZ Publish content staging solution

Using eZ Publish's siteaccess system combined with hidden nodes, you can quickly create a flexible content staging solution.


Making custom content scripts more efficient in eZ Publish

For those who write long-running scripts in eZ Publish to perform operations (move, rename, update, and so on) on many content objects, here are a couple of quick tips to speed up the scripts and make them more efficient.


Site performance optimizations: a look back at Election 2012

4 years ago, in 2008, we first met what is now one of our longest ongoing clients, Rasmussen Reports. There was some stress and urgency to their problem, as their site was crashing leading up to the most important time of the year for them -- the US presidential elections. We managed to stabilize their site and imagined a time in the distant future: a less stressful 2012 election period! The month leading up to November 6, 2012 turned out to be a record-breaking traffic month for a couple of our clients, including Rasmussen Reports. This time around, we had no website hiccups during an election season that saw more than twice as many visits in the peak month and an almost 3-fold spike in pageviews from the previous major election's 1-day peak.

Here are some of the site performance best practices we implemented in advance of the 2012 elections.


Re-indexing specific pages and subtrees in eZ Publish

There a few cases when you want to trigger a re-index parts of your site; for example, you might make an existing attribute searchable or you might change some index boosting settings. However, default eZ Publish indexing tools only allow you to re-index the entire site. This is not particularly efficient if you have a very large site and/or if you're just trying to test a small change in your development environment. Here are a couple of tools that you can use to re-index specific parts of a site.
