Varnish is great for high traffic sites where the same pages are served over and over to millions of visitors, but when you have to do something differently depending on the specific user or user group, things get complicated. There are several techniques, and how you might use them depends on the details. Here, we have outlined a solution for a particular use case on eZ Publish.

Index time plugins are one of the most important techniques of extending eZ Find functionality; they allow you to control how and what data is indexed. Combined with custom eZ Find queries, this opens up huge opportunities for providing access to content, well beyond mere 'search'.

In this post we will look at some typical use cases, briefly consider out of the box functionality and then dive into why you would want to make use of index time plugins and how you would go about setting one up.

Whenever you edit content in the eZ Publish Administration Interface, eZ Publish stores a new version. eZ Publish has a built-in feature to limit the number of previous versions it stores. However, as of the time of this posting, the eZ Publish 5.x public API to create and update content does not respect the version history limit (which, by default, stores 10 previous versions). We've written a quick function that restores this feature.

Fetching content the new way on eZ Publish 5.x.

In the following article we are going to show you how to fetch information in the new eZ Publish version considering that permissions may be set in place on different sections and we will compare it to how is it done in the legacy kernel.

During the flow of this article we will introduce a new undocumented method which is going to let us bypass permissions set to different sections.

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.

Rackspace recently released their newest generation of cloud servers, called Performance Cloud Servers. Unlike previous new releases, they've made a compelling case to upgrade existing cloud servers, as the "Performance Cloud" servers are cheaper, more powerful, and they use SSD storage. We decided to run some performance tests on an existing eZ Publish site, and saw between a 10-100% performance increase under high loads. 

Countless presentations are made daily about the ubiquity of smart phones and the new, groundbreaking uses of smart phone apps. However, in many cases, humble text message services can be more useful and efficient.

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.

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.

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.

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.

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.

Electronic media company Rasmussen Reports is best known for their US elections polling, but they do public opinion polling on a wide variety of topics, releasing new poll results on its website daily. Their multi-tier paywall subscription system has successfully helped them generate website revenue at different levels of user engagement.

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.

In the world of books, book publishing and bookselling, the metadata exchange format “ONIX” is the preeminent method of communicating information about a book. In spite of the fact that ONIX is a rather flawed standard and protocol for exchanging bibliographic information, it is the standard which everyone has settled on. Mugo has been working with ONIX since 2003, first building a freely available ONIX management system as a proof of concept for the Centre for Canadian Studies in Publishing at Simon Fraser University and most recently building a turn-key system for an ONIX website - that is - an ONIX powered website.

Open source communities rely very strongly on the community to advance the software in question. eZ Publish adds the "enterprise" part to "enterprise open source content management system" by not only targeting larger enterprises but by also adding a company vendor -- eZ Systems -- behind the software. This helps spur development forward on a consistent pace. However, there is still immense value in having the implementation partner companies contribute their code and insights. Contributing back might not be a natural thing for the partner companies to do; if you're such a partner company, here's why you should and how to do it.

As a web development company, we spend a lot of time deep in code, implementing solutions.  However, essential to our success is the proper use of additional administrative and communication tools to keep organized, to run smooth projects, and to interact with clients.  Skype, Dropbox, GitHub, and Google Apps are ubiquitous in the industry and embedded in our daily work.  An additional set of less obvious tools are also just as important to our work.

Rasmussen Reports runs a contest where visitors have to guess what an upcoming public opinion poll result will be.  Participants get points depending on how close they are to the actual result.  A new question is asked every week, making for a fun, recurring way for visitors to interact with site content. Here's how we developed the contest on top of an eZ Publish extension called eZ Survey.

Over the years we've worked on many websites in the publishing industry. Each has a unique set of requirements and challenges, but we've been able to refine and re-use a set of tools and best practices. These make up what can be called a "publishing package" built on top of the eZ Publish framework.

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

Optimizing the editorial experience in a Content Management System is a continuously evolving task. The challenge is to make the CMS an enabling tool to help editors publish content as efficiently as possible. In many organizations, specific requirements at each publishing step can be complex and dynamic. Here are 10 built-in tricks, ways to extend the interfaces, and ready-made custom extensions to unleash the power of eZ Publish content management.

Having multiple projects stored in one Subversion repository is a challenge if you want to move one of the projects to another repository. Also, over time, moves and deletions can bloat the size of your repository with obsolete, unused data. In this article, we will show you how to extract SVN projects to their own repositories, preserving full commit histories.

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.

I noticed a while ago on a client's website about Canadian books that some of the book nodes would have their url_alias broken and the url /content/view/full/<node_id> would be shown instead of the nice url. Running the updateniceurls.php would not solve the problem so I had a look at it and tried to see what could cause the problem and realized that the two tables ezcontentobject_tree (containing the node information) and ezurlalias_ml (containing the url_alias path parts) had different data for the same node.
