Doug Hercules (dhercjr on drupal.org) is a graduate of the 2012 class of the DrupalEasy Career Starter Program and currently working as an intern with DrupalEasy.This week I was tasked with learning how to automatically close comments on a node two weeks after the node is created. We initially looked into a couple modules that did this well, Comment closer and Comment commander, but since neither is quite ready for Drupal 7, we decided this would be a good opportunity for me to learn more about the Rules module. Maintained by Wolfgang Ziegler (fago) and Klaus Purer (klausi), this module allows you to define actions that are triggered automatically on various Drupal events as they occur. This blog post will walk you through how I accomplished this task.

Doug Hercules (dhercjr on drupal.org) is a graduate of the 2012 class of the DrupalEasy Career Starter Program (http://drupaleasy.com/dcsp) and currently working as an intern with DrupalEasy.This week I had the opportunity to clone a website from a git repository using Quickstart. Quickstart is a really quick, pre-made PHP Drupal development environment in a VirtualBox, which allows you to install a virtual machine to run Linux on your Windows PC. I've only gone through the process of cloning a site into Quickstart once before, and this time I thought I’d document it in my blog for myself and anyone else who might want to do this in the future. The general idea is this - there’s a site that I need to work on that is stored in a remote git repository. I want to get a copy of the site up-and-running inside Quickstart. To get started, I downloaded Quickstart, installed VirtualBox, then imported the Quickstart file into it.

Using Git to move the code base of a Drupal site from a local development environment to a hosting provider (or vice-versa) is a necessary skill that most Drupal site builders should have. Configuring and utilizing a remote Git repository can be an especially daunting task for people who don't have a strong background with version control systems.

How many times do you find yourself building the same bit of functionality on Drupal sites for various clients? Whether it be a photo gallery, multi-user blog, or slideshow, as Drupal site builders, we often find ourselves re-inventing the wheel. Personally, I’ve been asked to build slideshows on many client (and volunteer) sites that I’m involved with. Over the years, I’ve developed a recipe for a powerful and flexible slideshow that often exceeds the needs of all but the most particular clients. I recently added the ability for the slideshow to be responsive, and now seems to be a good time to share what I’ve done. At the end of this post, I’ve provided the slideshow as a Features that you can implement on your sites.

As part of a Drupal workshop that I'm teaching (the Drupal Career Starter Program), we've been discussing Acquia Commons. Our discussions led us to decide to have a local meetup specifically to learn more about it. Since we expect a number of newbies at the meetup, I figured I post a quick video showing how to get Commons up-and-running using Acquia Dev Desktop. I found it to be a little bit tricky, mainly because the memory requirements for Commons are a bit higher than for core Drupal. The video shows how to tweak a couple of memory setting in the php.ini file.NOTE: If you're using the Windows version of Acquia Dev Desktop, you can ignore the "apc.shm_size" change - it isn't used in Windows!

Let's face it - anyone with anything more than a passing interest in the Drupal community is probably aware that we're in the midst of embracing Git, "the fast version control system". As with just about everything else in our community, we are continuously jettising outdated technology and replacing it with modern solutions.

Drupal 6: Ultimate Community Site Guide (2nd Edition) was published earlier this year by Sun Flare Ltd.. Dorien was kind enough to participate in an interview with DrupalEasy's Mike Anello. Dorien Herremans runs Sun Flare Ltd, an organisation that specializes in Drupal development and consulting. She is a MSc Commercial Engineer in Management Information Services from the University of Antwerp, Belgium. 1. Dorien, please tell us a little bit about your book. The Drupal 6: Ultimate Community Site Guide could be compared to a very long tutorial on how to set up a community site with Drupal 6. Or better yet, sequences of small tutorials, that are integrated. Some of the features that are implemented are profiles, photo galleries, video galleries, forum, walls, private messaging, etc. Throughout the entire book, the reader is guided by the example site drupalfun.com. The implementation of every feature is described in detail, along with example screenshots. In essence, this book takes you by the hand in setting up a full featured community website.

Creating a well-organized, content-heavy website is difficult. Creating one that is also sustainable is even trickier. It's easy to keep adding features to a web site without considering how they fit into the overall plan until you get to the point where things start getting out-of-hand and site maintenance starts becoming a real issue (blame Drush for making it so darn easy to add new modules!)

One of the primary ways of keeping a Drupal site of any size running securely and at peak performance is to ensure that all of its modules stay updated. With thousands of modules in the Drupal eco-system, updates are released literally every day. Luckily, Drupal core's Update Status module helps site administrators keep notified of modules in need of updating.In this article, you'll learn how to use the power of Drush and Apache Subversion (aka "svn"), a revision control tool, to update your site's module quickly and safely. You'll be presented with two methods for solving the problem. The second method is much faster, but comes with a caveat. Read on.

In an attempt to point to some of the great things that are available using Features, I tried to look for a directory of Feature Servers. Sadly, Google was not very helpful. After some digging, I was able to locate a page on the OpenAtrium Community site called Distributed Feature Servers. This points to many of the other pages I was able to find via search. Utilmately I created a wiki page on the Packaging & Deployment group of groups.drupal.org, which seems to be one of the hottest places to discuss Features. Directory of Public Features Servers wiki page Currently, there is tons of info about how to create your own Features Server, but not much about where all the publicly available features servers are located. If you know of others, please go edit the wiki page on groups.drupal.org or leave them in the comments here.

I recently presented a talk at DrupalCon Paris titled, "45 Modules in 45 Minutes: The Best Modules You're Not Using". I hand-picked 45 modules that were not among the top 100 most downloaded modules from Drupal.org for the period of June 21 - August 16, 2009.

This is your moment, you've decided to step up and make a job board for your local Drupal User Group. You spend some time thinking about everything you'll need, including the job listings themselves. You'll want to gather the standard info, like job title and job description, salary, experience, the works. When it comes to gathering company info, your instincts make you take a few extra moments to plan. If you think about this from the perspective of the person posting 6 or 7 jobs, she would end up having to type (or at least copy and paste) the business' contact information each time. If you think about collecting 3 or 4 fields for each business, then that's about 20 extra form fields for the user to fill out. If she then decides to change the info, let's say she made a typo, she now must click through each edit screen 6 or 7 times. That amounts to hundreds of clicks and several hundred repeated keystrokes. There must be a better way. A nodereference can help your users. Once finished, you will have two nodes, one for a job and another for a company, and yet you will still display the information about the company inside the job listing. By the end of this tutorial, you should understand what a nodereference is for, how to create and use one, and finally, how to use template files to theme the output of the nodereference and get the most out of the relationship.

This article is also available in French from KolossalDrupal. There's an incredible amount of functionality that can be provided by the Views module, especially when it is combined with intelligent use of Node Reference fields. When you relate your site's nodes with Node Reference fields, these relationships can be easily leveraged to create some very useful views. I'm going to build a view for a sample music site. In the site, I have 3 related content types for "Band" nodes ("Black Eyed Peas", "Linkin Park", etc...), "Album" nodes ("Back in Black", "Bat Out of Hell", etc...), and "Events" (concerts, television appearances, etc...)

In the first three parts of this series, we've looked at what RDF will do for you as both a consumer and a provider of RDF data and we've had a quick primer on what exactly implementing RDF entails. Turning our attention back to Drupal, this article will take a look at the state of RDF in Drupal 6 and some of the available contribued modules. Tomorrow's article will take a look at what the next version of Drupal will offer in terms of RDF. Drupal 6 does not have any RDF functionality in core. If you want to implement anything having to do with RDF in Drupal 6, you'll need to utilize contributed modules. Only a few of the RDF-related contribued modules for Drupal have even had official releases - the majority of them are still somewhere in the development process. While reviewing the existing RDF modules for Drupal 6, I found that I could categorize them into two categories - "Provider Modules" and "Consumer Modules". Those in the former category are designed primarily to help you RDF-ize your site's content. Modules in the "Consumer" category are generally designed to help you consume, use, and display RDF data from various sources. In some cases, there is some overlap, so this categorization is more for convenience than anything else.
