CHAPTER 16 CHANGING THE LOOK OF YOUR BLOG 453 Listing 16-12. Final Version of the Recent Comments Code in index.php

%comment_author% on %post_title%

“); ?>

As you can see in Figure 16-17, the list is much less cluttered now. As a bonus, hovering over the link to the comment gives the comment excerpt as a tool tip. That s the title part of the code in the format parameter used in Listing 16-12. Figure 16-17. The finished recent comment list Cleaning Up the Code You have modified an existing theme, expanding it to do what you want. However, a couple areas could use some cleaning up. These involve making the PHP code safer and eliminating duplication in the CSS rules.

452 CHAPTER 16 CHANGING THE LOOK OF YOUR BLOG self-explanatory. For example, %comment_author% will be replaced with the comment author s name, and %comment_excerpt% will be replaced with the first few words from the comment. You could also have the plug-in output a link to the comment author s web site, if the comment writer provided one. The rest of the format parameter (taken from the plug-in author s example) puts the comment details in a list item with the link to the post on a separate line. Figure 16-16 shows the output. Figure 16-16. A different version of the recent comments list This version gives more information, but it seems rather cluttered and the most important information the name of the post and its link isn t easy to discern. So, let s make one more change to this code. You will remove the comment excerpt and just link to the comment, but with the post title. Surprisingly, although this plug-in has more than 40 replaceable tags, none of them match the desired format exactly. You could have the post title as a link to the post, or the post title as a link to the top of the comment section, but none have the post title as a link to the specific comment. However, you can create this format by using two separate replaceable tags, as shown in Listing 16-12.

CHAPTER 16 CHANGING THE LOOK OF YOUR BLOG 451 Figure 16-15. Recent comments listed This is a useful addition to the blog, but it could be better. It doesn t show to which story or post the comments belong. A reader might be particularly interested in what other people have to say about a story he commented on recently. A contributor might be looking for comments on her own stories. As its name implies, the Customizable Comment Listings plug-in is flexible enough to accommodate such additions. Let s replace the simple call to the plug-in function with the code shown in Listing 16-11. This is another example provided in the plug-in s documentation. Listing 16-11. New Version of the get_recent_comments Template Function in index.php

%comment_author% said “%comment_excerpt%” in
%post_URL%

This function looks complicated, but it has only one more parameter. It uses a very powerful format template Scott has defined. Each of the terms enclosed in percent signs (%) is substituted by some data from the list of recent comments. The substitution names are fairly

450 CHAPTER 16 CHANGING THE LOOK OF YOUR BLOG Adding a Recent Comments Plug-In Now you will install another plug-in, which will list a number of the most recent comments to the blog in the sidebar. This is great mechanism to keep your readers interested. It allows them to see which topics are still being discussed, and thus is an added incentive to keep reading those topics and to continue to get involved. Real conversation about a shared interest between your readers is the lifeblood of an active online community. The plug-in is the Customizable Comment Listings plug-in by Scott Reilly. You can download this plug-in via Scott s site at http://www.coffee2code.com/archives/2005/03/30/ plugin-customizable-comment-listings/. Download, install, and activate the plug-in using the procedure covered in Chapter 15. Read through the comprehensive documentation on Scott s site. Next, add the code shown in Listing 16-9 (from one of the examples in the plug-in s documentation) to the index.php template file, just before the contribute section. The single parameter 5 tells the plug-in to list only the five most recent comments. Listing 16-9. Code to Insert into index.php Immediately Before the Contribute Links

Now add some more CSS rules to style the list of comments the same as the other lists on that page, as shown in Listing 16-10. Listing 16-10. Additional CSS Rules for the End of style.css ul.recentcomments { list-style-type: none; margin:0; padding-left: 10px; } ul.recentcomments li { margin-top: 4px; margin-left: 1em; text-indent: -1em; } Figure 16-15 shows what the default output of this plug-in looks like. Below the del.icio.us links, you have a list of the five most recent comments with the name of the comment author and the first few words of the comment. Those few words are a link to the individual comment itself. If a reader clicks the link, she will be taken to the blog post commented on with the page scrolled to the individual comment.

CHAPTER 16 CHANGING THE LOOK OF YOUR BLOG 449 The call to wp_loginout produces a link to the login page if the current visitor is not already logged in, and a logout link if the visitor is logged in. Next, add the CSS rules from Listing 16-8 to the end of the style sheet. This will ensure the display of the links matches that of the other parts of the sidebar. Listing 16-8. CSS Rules for Login and Register Links Added to style.css ul#contribute { list-style-type: none; margin:0; padding-left: 10px; } ul#contribute li { margin-top: 4px; margin-left: 1em; text-indent: -1em; } Figure 16-13 shows how your register and login links should appear, and Figure 16-14 shows the site admin and logout links.

The improved list of links Adding Registration and Login Links Something missing from this template are the links to register and log in to the blog. Most WordPress blogs, being one-person blogs, don t need these links. Many themes don t even bother to include them. For a community blog, you will want to add them to your theme. To the index.php template file, add the code highlighted in bold in Listing 16-7. Listing 16-7.
