Drupal is a free, open-source content management system (CMS) for a variety of platforms. It has a robust user community and easy-to-use administration features. Drupal Essential Training covers all the important aspects of installing, configuring, customizing, and maintaining a Drupal-powered website. Instructor Tom Geller explores blogs, discussion forums, member profiles, and other features while demonstrating the steps required to make Drupal perform. He also teaches fundamental concepts and skills along the way, including installation, backups, and updates; security and permissions; flexible page layouts and CSS; menu navigation; and performance monitoring and disaster recovery. He also discusses how to select and install the community-supported modules that further expand Drupal's capabilities, and gives experienced PHP programmers tips on customizing page templates. Example files accompany the course.
Drupal 6 enables two content types by default, Stories and Pages, but it actually installs four others, leaving them disabled, probably to avoid confusion by Drupal newbies. We'll show you how to turn them on. So, you can start creating Blogs, Polls, linked articles called Books, and message boards, which Drupal calls Forums. In fact, we are going to go and turn on Forums first. Go to Administer, and then go down to Modules, and, of course, as always, you see a list of the modules that are available. We already turned on one Content type called Blog.
Now, we are going to turn on Forum, just by clicking in here and scrolling to the bottom and clicking Save. You will also notice Book and further down Poll, we leave those Off for now, but we click Save, so that we have Forums. Now, when we go to Create Content, we will see four things listed, Blog Entry, Forum Topic, which was from the new module that we just added, Page, and Story. Page and Story again are default, built into Drupal. Let's go to Administer and then to Content type so that we can see all of those and change some of their criteria and the way they behave.
Again, we see all four; interestingly, Page and Story can be deleted, even though they were installed by default. Blog Entry and Forum Topic, however, cannot. That's because these are created by Modules and the only way to turn them Off is by going back and turning off the Module in the opposite way that we have just turned them on. Most content types are quite similar and if we go to Create Content and click on any one of these, you will notice the similarities. They have a Title, a Body, and then perhaps some other fields. Once again, we go to Create Content and Create Forum Topic, still it's called Subject, but it's basically the same thing. Now, let's go and create our own custom Content type. To do that, we go to Administer, Content types, and Add content type here at the top. We are going to create a content type that's just going to be a test and we are going to delete it before we are done, and in fact, we'll show you some of the effects that happen if you accidentally delete a content type and how to get back, if you do so; because doing so, when you have content, that's in that Content type can cause a lot of problems.
For our content type, we'll call it Test content type; under Type we are going to simply enter Test. This is the machine readable name of the Content type. It should be as simple as possible and you can see from the text underneath, it limits the sorts of characters that you can use in this name, I always just enter with lowercase, very simple, just enough so that I know what it is, because again, I don't have to see it. What I'll be seeing mostly is Test content type, what the machine is going to see is Test. Under Description, just to make sure that we don't accidentally put any content in that we really want to keep, I'll say, "This is a test content type. Don't put anything you really want to save in it!" And then at the bottom, you will notice some settings that are very similar to when you Create Content.
In particular, this is Workflow Settings. The thing is this is going to be the default. So that, whenever you click Create Content and choose this test content type. This is what's going to show up unless the person changes it. Since, I like to create a new revision every time I create some content, I am going to check this; that will force the person to uncheck it, if they want to create a new revision. There are two other dropdown menus here, which are a little bit different. One is Submission Form Settings. Let's click on it. This really just let's you change what the field labels are; in other words, instead of Title you might want to say, Address of Property and in Body, you can say Description of Property. Again, this is a test that we are doing, so we'll be deleting this later. Of course, if you create your own Content type you could put in whatever you like. Minimum number of words is a nice little thing. If you don't want people to just be posting and saying, " I agree with that," then you can say, you know, you have to write 100 words or it's not going to go up, we are just going to leave it at zero for now.
Finally, you can have submission guidelines, for example be bold, be brave or whatever you like, of course. Scrolling down there is one other thing, Comment settings. These are quite complex, they let you determine whether or not you are going to allow people to comment in here, not only that they'll also let you determine how the comments will be displayed - if they'll be showed in a threaded list, if they'll be sorted oldest first or newest first, and so forth. We are going to disable comments on this content type. We do discuss comments more in another video that's specifically about managing comments. Scroll to the bottom and Save Content Type.
Good, so we've created, as you can see, this Content type called Test content type. Now, let's switch to an ordinary user and see if that person can create some content in that Content type, switching over by holding down the Command key and hitting Tab on the Mac keyboard. We already have a window opened in Firefox with our ordinary fishyjoe. Click on Create Content; wait, we don't see our test content type, that's because we didn't give permissions to create that Content type.
Let's go back to the Administrative user, go in to Administer and our old friend Permissions. Click on that and you'll notice as you scroll down in the node module there is a new choice, create test content. Since I know fishyjoe is a Contributing user, I am going to say, "Yes, he can do it." Ordinarily, authenticated users can't, but he can because I trust him as a contributing user. Scroll down to the bottom of the screen, click Save, and now let's go back to fishyjoe.
Now, click Create Content again and there it is, test content type. You'll notice that when you hover over test content type, it gives you that little help text that we mentioned before. Let's click on it now and actually create something, Address of Property, we will say at 819, 15th Street, Description of Property, "Boy, this is place is swank !" Scroll down a little bit further and we can see it's forcing revision information. So we'll say, Created new story and Save; and there we are, we have our new piece of content in test content type. You may remember that we also had, Promote to front page checked.
So, let's go to the front page and see if it's there; click here, remember we had this as sticky at the top of list. So, it will show up underneath and there it is, we had Comments turned off, let's make sure that's true, by clicking on the Title - nope, no place to add comments, good, it's all working exactly as we wanted. Now, here is a tricky thing. We go back to the administrative interface, click on Administer and Content Types. We notice that we can actually delete that Content type. What happens if we do though? Say Delete, this is going to be tricky, don't worry we will come back to it and we'll make everything all right again. We are going to delete this Content type.
So, we have deleted the test content type, but is it still there? Is the content that was in that Content type still on the site? Let's go back up, take a look at our front page, yep, it's still there. We click on it and we see it's still viewable. When we click on Edit however, it doesn't work. It doesn't work because we've deleted the Content type and so as you can see Drupal doesn't know what to do what to do with it. This is a node which has no Content type attached to it and we can prove that by going to Administer, Content which lists all the content on our site. See how all of these have types, this story doesn't have a type.
So, we can't edit this particular story. Let's go back to it and we can't even delete it, there is no place to delete this story. I am going to click Back, to go back to our list. There are a few things that we could do however. We could go in and we could copy the text and just post it as a story or page or something else. There is one other way that you can make this content editable again, which is to change it to a different type. To do so you will have to go into MySQL, through the phpMyAdmin interface. We are going to that by switching to MAMP or WAMP, if you are on a Windows server, open start page and, of course, phpMyAdmin. From there you will choose your Drupal database which we've named Drupal and then scroll down until you get to node. Click on this little icon, which let's you browse the node that is all the content in your site and scroll down until you find the node that you want, but notice that as a type, it's still test which doesn't exist anymore, we are going to change it to Story To do so, click on the little pencil icon and then simply type in Story, scroll back down to the bottom, click on Go, then we are going to switch back to our Drupal interface and reload this page and there we are, it's now a story and we can actually edit it again.
Just to clean everything up, we are going to delete this piece of content, you might ask yourself, 'why would I want to define a Content type anyway?" It's not really apparent from the way, Drupal set up by default, by development of good Content types leads to tremendous flexibility in both Content creation and display.
