For a previous article I covered the various ways you can export user data using eZ Publish. In the article, I suggested how you can export all users who have logged in over the previous month using an extended attribute filter.

We’ll start by creating an extension to house our filters followed by building a basic filter to return a list of users who have forgotten their passwords. We will then create a filter to tell us how many/which users have logged in over the past month.

This seems especially to be the case with the templating functionality for Strings. Common PHP tasks such as str_replace are just not available. There are two simple solutions for this.

Every page you visit in eZ Publish uses the PageLayout File to create the structure of the page. For XML or AJAX based content you do not always want this to be the case. To get around it, you can add a new layout without a pagelayout template associated with it.
