Content attribute transformation or conversion in eZ Publish isn't required as often as data import or data migration, but when it is, it can take a similar amount of effort. eep simplifies the process with its flexible built-in attribute module options.

When working with eZ Find fetches, you may want to return only a specific sub-set of data for each of the search results, rather than the whole content object.

You can do that by using the eZ Find 'search' fetch's 'fields_to_return' parameter.

In eZ Publish 5.x and eZ Platform, the concept of "view cache" has changed. The "module result" part of it (which was basically page-level caching if we didn't count the pagelayout) has been offloaded to HTTP caching, most often implemented with Varnish. In addition, Cache blocks no longer exist and have been replaced by ESI (Edge Side Includes) blocks.

The persistence caching element -- that is, caching of your actual content from the database -- of the "view cache" still exists, handled by default on the file system through the Stash bundle. Stash also supports memcache (which, as its name suggests, uses memory, and has a much better performance). We use memcache(d) for all of our production sites.

Custom tags are very useful for adding custom functionality to rich text fields beyond simple formatting and embeds. Here is a walkthrough of how to implement custom tags in eZ Publish 5.x compared to an eZ Publish 4.x / legacy install.

When running an intranet or an otherwise password-protected site, you sometimes need to share confidential or sensitive files, specifically PDFs. It is a challenge to balance the confidential nature of the files while allowing privileged users to download and work with the files normally. One lightweight approach is to stamp a watermark onto each page of the PDF. Instead of just a big "confidential" watermark you can customize each download so that each file is stamped with, for example, the current user's name and the current date.

The eZ Publish 5 series has been a successful step forward for eZ Publish with the adoption of the Symfony stack and the ability to run dual kernels with the new and legacy stacks. However, content preview functionality has gone through many fixes through the 5.x version. The final fix comes in eZ Publish 5.4.5, which is very important since eZ Publish 5.4 is a milestone release that will be used as a stepping stone for upgrades through to the 6.x series aka eZ Platform! Here's how to update your code to make your editors happy with proper content preview!

The eZ Publish search extension eZ Find offers many sorting parameters for its search results, the most common being by relevance / score, and by date. On large sites, sorting by date can lead to non-relevant results showing up first. What if you want to sort by date and relevance, essentially boosting newer content but still giving you relevant results?

As of eZ Publish 5.4 / 2014.11, there is a new way to define custom image filters and image aliases. This is because image alias generation is now using LiipImagineBundle, with the underlying Imagine library from avalanche123. In this post we will review the old and new ways of configuring image aliases and filters along with a useful example.

A good caching system keeps elements in the cache as long as possible, but clears them as soon as the elements are updated. For content pages in eZ Publish and most content management systems, "purge-on-publish" features are well documented. When it comes to JavaScript and CSS files, there are usually different caching systems involved, and these are important to configure. Otherwise, you'll end up with the all-too-familiar problem of a broken front-end on deployments, where the only fix is to have users do a "hard refresh" (CTRL+F5) in the browser.

When working with a CMS, you might decide to store some files in Dropbox rather than in the CMS for several reasons, including storage, workflow, and performance considerations. The Dropbox Chooser is one of 2 Dropbox Drop-ins. The "Chooser" enables users to generate a file link from a Dropbox account, and the "Saver" enables users to save a file to a different Dropbox account. The Chooser is often most useful for CMS editors.

Using the Dropbox Chooser with the eZ Publish Administration Interface saves editorial staff a lot of time by giving them direct access to the file links they need without having to jump between Dropbox and eZ Publish. The Chooser UI also allows you to upload files to a Dropbox account, making it even easier to get everything done within one operation.

eep (Ease eZ Publish) is a command line tool we introduced in a previous post, which in combination with other command line tools like awk, grep and xargs makes for powerful one-liners. The examples in this post will highlight its versatility and show just how quickly and conveniently eZ Publish related tasks can be accomplished using eep. Get ready for some command-line fun!

When using eZ Publish's eZ Find extension on a public facing site or project -- arguably any project -- it is vital to secure it to prevent unauthorized access and potential data loss. eZ Find is powered by Apache Solr, an open-source search server based on the Lucene Java search library. Its power and flexibility make eZ Find a great tool when working with a lot of content in eZ Publish.

There are a number of ways a Solr installation can be secured. We'll look at BasicAuth via Jetty UserRealms and iptables firewall rules in detail.
