Video: Adding RSS secondary content

Now that Drupal is set up with our main content, known as Nodes, we can add some secondary content to our flower shop site. For this site, we will be subscribing to an external RSS news feed, which will show up in a sidebar next to our main content. If you're unfamiliar with RSS, it's a new technology that allows you to subscribe to a website's content without having to visit that page. So, starting from our Administer screen, we can actually go to the Feed aggregator administration page.

Drupal is widely recognized as a powerful back-end system for web sites, but Drupal 6: Creating and Editing Custom Themes shows how the application can also be used to manage the look and feel of a web site. Web architect Chris Charlton introduces the core themes that ship with Drupal. He shows how to install and administer new themes, change color schemes, and add sub-themes to existing themes. He also demonstrates how to build a custom theme from scratch; integrate HTML, CSS, and JavaScript; and apply themes to specific nodes and blocks. Exercise files are included with this course.

Topics include:
  • Setting themes and theme permissions
  • Using the Color Module to change color schemes
  • Building sub-themes
  • Adding HTML, CSS, and JavaScript to themes
  • Understanding templates
  • Applying themes to pages, nodes, and blocks

Adding RSS secondary content

Now that Drupal is set up with our main content, known as Nodes, we can add some secondary content to our flower shop site. For this site, we will be subscribing to an external RSS news feed, which will show up in a sidebar next to our main content. If you're unfamiliar with RSS, it's a new technology that allows you to subscribe to a website's content without having to visit that page. So, starting from our Administer screen, we can actually go to the Feed aggregator administration page.

So on Administer, find the link, Feed aggregator. If you do not see the Feed aggregator link, that's because the aggregator module has not been enabled yet on your site. You need to do that before we can add an RSS feed. So, clicking on Feed aggregator, we are now brought to the Feed aggregator page, where we see that there are no feeds added to our site, currently. So, we are going to go up into the tab area and click Add feed. And we see to add a feed, we need to supply both a title and a URL for the RSS feed.

For this site, we are going to add the Drupal News RSS feed. And we are going to get that, actually, from the official Drupal webpage. So, this is the official Drupal homepage, drupal.org, and at the bottom of this site is actually a little icon known as an RSS icon. We can right-click and copy the link pointing to this RSS icon and we can come back and actually paste into the URL and click Save.

If you're unfamiliar, again, with RSS, you will actually start to notice that little RSS icon appears on many other sites. And as you see, at the bottom of the New York Times website, for example, they also carry RSS feeds and they use the same icon. So, you should be able to subscribe to your favorite sites through their RSS feeds. Okay, going back, we now can close these extra tabs and going back to our Drupal we see that the feed Drupal News was successfully added.

So, let's check that. We click on List in the Feed aggregator screen and we see Drupal News actually comes up listed. But we notice that there are zero items here. That's because the feed was never updated. Now Drupal can auto update these feeds on its own, but we need to tell Drupal to update right now, because we would like to see this content. So, instead of waiting for Drupal, we clicked update items and now we see that there are 25 items listed in this feed. Well, how can we be sure of that? We can click the feed title from the screen.

I am going to open it in a new tab, wisit the Feed aggregator screen, and now we see that there is content that we do not add by hand to our site. This is all the RSS content coming in from the Drupal News feed. So, I am going to close this screen and go back to the Feed aggregator screen. So, not all Drupal sites will need or use RSS feeds and as we will see it later, these feed items will get themed just like the rest of the site content.

Q: I'm editing the code in the file page.tpl.php as shown in the movie "Building a sub-theme: Adding custom theme regions":

<?php if ($content_top) ?>
<div id="content-top" class="clear-block">
<?php print $content_top ?>
</div>
<?php endif; ?>
 

But the browser shows the following error message: 
Parse error: syntax error, unexpected T_ENDIF in /home/u/u5522419/www/drupal/sites/all/themes/subgarland/page.tpl.php on line 80.
A: The code is incorrect. (The syntax error, by the way, displayed indicates which line of code contains the error.) The line containing the IF statement is missing the colon character ( : ). It should read:
<?php if ($content_top): ?>
Q: I have a button in Flash, but Internet Explorer is blocking it from opening up. At the top of the window, a message appears saying "Pop-up blocked. To see this pop-up or additional options click here..."
What can I do to this button so that it opens a new browser window and keep IE from thinking it's an unauthorized pop-up?
A: To get around the pop-up blocker, try using the "_self" parameter in Flash. So instead of:
navigateToURL(myURL);
use:
navigateToURL(myURL, "_self");
