Video: Learning key terms in Drupal

As with any community the Drupal world has its own slang. Fortunately, there is not too much of it. But understanding the few Drupal specific terms there are will help you to communicate not only with others who use Drupal but also to understand some of the concepts you'll need again-and-again as you create your Drupal site. The first important concept is that of the node. In Drupal a node is any piece of information that you create as a single unit. For example, when we click here on the drupal.org website we see this page which is a node. It may link to another nodes as it does here, and it may appear as part of a page, a story, a blog post, anything like that. They are all nodes.

Learning key terms in Drupal

As with any community the Drupal world has its own slang. Fortunately, there is not too much of it. But understanding the few Drupal specific terms there are will help you to communicate not only with others who use Drupal but also to understand some of the concepts you'll need again-and-again as you create your Drupal site. The first important concept is that of the node. In Drupal a node is any piece of information that you create as a single unit. For example, when we click here on the drupal.org website we see this page which is a node. It may link to another nodes as it does here, and it may appear as part of a page, a story, a blog post, anything like that. They are all nodes.

The second concept is a content type. Content types distinguish one type of node from another. In that list I just gave page, story, blog post each of those is a content type and can be treated slightly differently in your Drupal site. You will see more of that as the course progresses. The third concept to know is that of the module. In Drupal a module is a piece of software that you can put into the Drupal to give it additional functionality. On the drupal.org website you get modules from Download and Modules and here as you scroll down, you can see a list of categories of module.

Next to them is the number of modules that are available in that category. As you can see there are many modules in Drupal and we will be talking about several of them throughout the course. Another concept in Drupal is that of the theme. A theme is a unified graphic presentation for an entire Drupal site. I will give you an example. You see the blue area at the top of this site and the typefaces of a certain sort? If you go to the another Drupal site, in this case savemyhomebook.com, which is my own website You see that it has a completely different look, different typefaces, different colors, different layout and so forth, that layout stays the same as you go from page to page to page. And in fact the Theme is what defines the look of the entire site.

The next word to know is Core. The Core is the basic set of modules that included with the default Drupal download. The Core is broken into two parts, Optional modules and Required modules. The Required modules are the very centerpiece of the Drupal project, without them, you can't run a Drupal site. Fortunately, they're all included in the download that you can get from the front page of drupal.org. The next word to know is Template. A Template is a file in the programming language PHP that defines how nodes of a certain content type will appear. For example, if your site was a catalog of products, you could create a content type called Product Listing and then build a custom product-listing template so that all products are presented in a distinct but unified format. Building templates is a very advanced subject and we will only touch on it briefly in the PHP chapter later in this course.

The next term to know is Taxonomy. A taxonomy is how you put items into categories; you might know this from other websites as tagging. For example, let's say that you have a story about the election race for a local town's mayor that might be put into a politics category as well as a category that has the name of the town. These categories and the system that you set up to put that story into those categories is known as its Taxonomy. Drupal allows a very broad system of taxonomies and you will see how that works also in this series.

The next term to know is Aggregator. An Aggregator is a program that collects information from various sorts and puts them in one easy to read place. It's also commonly known as an RSS Reader. Drupal has an Aggregator built into it, so you can display syndicated content from many places on your Drupal site, and if you return to my site savemyhomebook. com, and go back to the home page, this latest foreclosure news is actually using Drupal's aggregator, it pulls in new stories from around the web and posts their headlines here.

Another term to know is Drupalcon, and you can see that on the home page of drupal.org, if we click on it, we go to its home page at drupalcon.org. Drupalcon is a semi-annual gathering of Drupal developers, and that gathering moves from city-to-city. As you could see the one coming up next as we're making this video is in Szeged, Hungary. Another part of the Drupal community whose name you should know is the Drupal Association. The Drupal Association is an organization dedicated to as the website says, Helping the open source Drupal CMS project flourish. Its President is Dries Buytaert, who is Drupal's original creator. You can go to the Drupal Association's website at association.drupal.org.

The last word to know is an odd little word for an odd little item, Druplicon. The Druplicon is this little mascot up here that looks like a drop of water. And there you have it. While discussions on drupal.org can get pretty technical you now know enough jargon to understand most of what you read there.

Q: While following along to the installation instructions in the “Installing WAMP and Drupal on Windows” chapter in the Drupal Essential Training title, an error occurs when attempting to open the local host page. Nothing appears except for an error reading “WAMPSERVER server offline.” What is causing this?
A: There is a known problem with some versions of WAMP that include a version of PHP (5.3) that some versions of Drupal is not compatible with. See http://tomgeller.com/content/tips-running-drupal-windows-using-wamp#comment-831 for more information.
If that is not causing the issue, reference the tips at http://tomgeller.com/content/tips-running-drupal-windows-using-wamp.
If you don't see the solution at either of those links, try using another AMP stack, such as XAMPP or the Acquia stack installer. See http://tomgeller.com/content/what-hells-wrong-drupal-wamp for discussion about these.
Q: After installing XAMPP and running Drupal for the first time, the Administration menu does not appear. What is the reason for this?
A: There are several possible problems. Here are some likely solutions. (These may also solve problems encountered with other AMP stacks.)
  1. Increase XAMPP's PHP allocation.
  2. Check to make sure all XAMPP's paths are correct and that permissions are correct. If the database information appears, but not Drupal's supporting files, and an included theme is being used, the supporting files will be in the /modules folder.
  3. Another solution is to not use WAMP or XAMPP. One option is to use Acquia's Drupal Stack Installer ("DAMP"), which can be found at http://www.acquia.com/downloads. However, that installs Acquia Drupal, which is a version of "normal" Drupal extended with additional modules. If  only core Drupal is desired, see the instructions at http://acquia.com/blog/kieran/try-drupal-7-alpha-your-laptop-or-desktop. (The instructions are for Drupal 7, but will work for Drupal 6 as well.)
Q: In the "Using the example files" movie, the method of importing information to the database is shown, using the backup in Chapter 10. When attempting to do this, the following error is shown: "No data was received to import. Either no file name was submitted, or the file size exceeded the maximum size permitted by your PHP configuration. See FAQ 1.16." The system is running the latest versions of Apache, PhP and MySQL, on Windows Vista. What could be causing the problem?
A: This is probably caused because your AMP stack allocates too little memory to PHP. 
 
That's especially true if you're using WAMP, which only gives PHP 2MB of memory, when it really needs at least 16MB. 
You'll see the issue if you go to the MySQL-controlling phpMyAdmin screen (probably at http://localhost/phpMyAdmin) and click "Import": The maximum file size allowed is 2,048K. That's only 2MB, and the databases for most Drupal sites are much larger than that. (The example site for Drupal Essential Training gets as big as 5MB.) The video "Installing WAMP and Drupal on Windows" shows (at around 3:30) where the php.ini file is, but here are some more-complete instructions to increase that memory limit. 

  1. Click the WAMP icon in your system tray.
  2. Select "PHP". In the side menu, select "php.ini" to open a file containing PHP's configuration options.
  3. Search for the line, "upload_max_filesize = 2M".
  4. Change it to "upload_max_filesize = 32M" (or whatever you like). 
  5. Save the file and restart WAMP. (Better yet, restart your computer entirely to be sure. I'm frankly not sure whether it makes a difference.)
  6. Now go back to that "Import" screen in phpMyAdmin: You should notice that the limit has changed.
Q: I don't remember the default username and password used demonstrate Drupal.
A: The default username used in the course is "admin"; the default password is "booth".
Q: How can I change Drupal's administrative username and password?
A: If for some reason the default exercise file username (admin) and password (booth) don't work, you can change them in the database itself using phpMyAdmin. (This technique is demonstrated in a video from Chapter 8, "Recovering from disasters".)

  1. Open your Drupal database with phpMyAdmin.
  2. Go to the "users" table. Click the Browse icon.
  3. For the row where uid = 1, click the Edit icon. (Note the value under the "Name" column: That's the administrator's username.)
  4. In the "pass" row, select "MD5" under the "Function" column
  5. In the same row, enter your new password under the "Value" column.
  6. At the bottom of the screen, click the "Go" button. You should now be able to log in with that username and new password.
Q: In Windows Vista, the WAMP icon disappears from the system tray after a certain amount of time. How do I get it to reappear?
A: To make the WAMP icon reappear (so that you can access localhost, phpmyadmin, php.ini, etc.), you have to activate the "start WAMP server" icon (from start menu, desktop or wherever). The system tray icon will reappear.
Q: My .htaccess file disappeared. What caused this?
A: A few times during the Drupal Essential Training video series, the instructor says to copy a Drupal installation by selecting all the files in the folder and then "dragging and dropping" them, either to a server or another location on your local computer. This is not the best way to do so, as the hidden file ".htaccess" will not be copied. 

There are two ways to get around that problem: 
  1. When installing Drupal for the first time: Instead of copying files from the Drupal folder, move the entire folder to its target location and rename it. This is the easiest solution for those without experience with Unix. 
  2. Use the command-line interface to copy the .htaccess file.
Sorry for the error.
Q: In the video, the instructor says the current version of Drupal is 6.3, but on the drupal.org site, the latest version is 6.17. Which is the newer version of Drupal?
A: Drupal 6.17 is newer than version 6.3. For some reason, the the version numbers go 6.3, 6.4... 6.9, 6.10... 6.17. It’s counter-intuitive, but that’s the order.
Q: My WAMP phpMyadmin will not allow me to upload the exercise files. It returns this message: "No data was received to import. Either no file name was submitted, or the file size exceeded the maximum size permitted by your PHP configuration. See FAQ 1.16." There was no previous database to drop, so what do I need to do to make this work?
A: This is a common problem, caused not by Drupal, but by WAMP. WAMP only allows you to upload files of 2MB or smaller, which is much too small. The solution is detailed at http://tomgeller.com/cant-import-a-drupal-site-in-windows.
