Chapter 8 ■ Drupal Blocks appear at the top of the list. After making the changes to the blocks, scroll to the bottom of the page and click “Save blocks,” which commits the changes to the Drupal database. Revisit the homepage of your website, and you will see the changes that you just made. Configuring Blocks You can select various configuration settings for blocks on the “Configure block” page. The configuration options include overriding the title of the block and setting the visibility of the block based on several optional parameters. As an example of how you might use these features in the future, let’s change the “Who’s new” block so that it only appears on the homepage of your site, and only when the visitor is a user who has logged into the system with a user ID and password. To make these changes, navigate to the “Block layout” page and locate the “Who’s new” block. If you haven’t assigned that block to a region, do so now by following the steps in the previous section. Next, click the block’s Configure link. This reveals the block’s configuration page. See Figure 8-3. Figure 8-3. The configuration page for the “Who’s online” block 94
Chapter 8 ■ Drupal Blocks On this form, you can override whether the title of the block “Who’s new” appears on the page when the block is displayed (uncheck the “Display title” check box), specify how many users will appear in the list of who’s new (“Items per block”), override the title by checking the Override title box and entering a new title in the text field that appears when you check the box, and assign the block to a new region. You may wish to only have this block appear on certain pages on your site. By default it appears on every page. For example, you may want the “Who’s new” block to only appear on the homepage of your site. At the bottom of the “Configure block” page (see Figure 8-4), you will see the Pages tab in the Visibility section. To set the block to only appear on the homepage, click the “Show for the listed pages” radio button and enter in the text box ( is the special term used to represent the homepage of your site). You could also specify other pages by entering the URL of that page in the text box (for example, /content). Figure 8-4. Choosing Visibility settings It is also possible to set a block so that it only appears for specific types of users based on their assigned roles. Click the Roles tab to examine and set the visibility by user role options. As an example, let’s set the block to only appear when the person visiting the site is logged in. (See Figure 8-5). Figure 8-5. Choosing roles-based settings Once you have clicked the “Authenticated user” check box, you can click the “Save block” button at the bottom of the page and return to the homepage of your site. To test your changes, navigate to a page other than the homepage and you’ll see that the “Who’s online” block is no longer displayed. Log out and return to the homepage and you’ll see that the “Who’s new” block no longer appears because you are no longer logged in. 95
