If you have posts that include the
nofollow attribute on links, you may at some point decide to remove them. By default, WordPress doesn’t insert
nofollow attributes in post content, but there are a variety of plugins that will insert
nofollow into all links in post content.
Or perhaps you have been manually adding
nofollow tags to your post links for SEO purposes. Regardless of how they got there, it’s very easy to clean things up and remove all
nofollow attributes from post content.
Tag clouds accomplish their varied font sizes by applying inline styling to each tag. The resulting font sizes can be really weird with values like
Of course, there is nothing inherently wrong about that, but it feels a bit unsettling and less controllable. Awesomely, Mike Summers sent in a solution he uses on his own site..
I like the idea of shutting off comments after a certain number of days. Here on Digging Into WordPress we do it after 90. After that kind of time, the “community” of the discussion is long over. I think a good practice for turning off comments is to instead leave a message informing visitors that the comment thread is closed, and offer a course of action in case they have something of grave importance to share. Here is an example from CSS-Tricks:
I had the occasion yesterday to have a page with a section on it where it would output a very specific set of other pages, which would need to change dynamically. What I could have done is built a special page template for this page, and inside that template run a
query_posts() to get these posts. But I wanted this page to remain editable from the admin. Besides, creating a special page template every time you need to do something like this is too cumbersome. WordPress is extensible enough to do better.
David Hollander of SparkWeb Interactive sent us in a little code clip for inserting Google Maps into Posts/Pages by the use of shortcodes. Google actually has copy-and-pastable iframe code already in Google Maps that is really easy to snag, but David was having problems with the Visual text editor screwing up the code when saving the Post. With a short code, no problem.
By default, WordPress generates an RSS feed for the comments on every published post. Many sites take advantage of this by displaying a feed link next to the comments area. This enables visitors to subscribe to the comment thread and stay current with conversation. It’s convenient, simple, and super useful. For example, a typical feed menu for many blogs includes the following items:
I heart plugin authors. Their work is generally amazing, a huge benefit to the community, the reason why WordPress rules so much, and deserving of much worship. That being said, plugins can do some pretty rude things sometimes…
When you are building a theme, and the circumstance comes up where you need to create a link to a specific page hard-baked right into the theme, there is a function you should be using.
WordPress’ powerful action-hook system makes it possible to insert functionality at any point in your theme. Most WordPress themes include some of the built-in WordPress hooks by default. For example, most of us are aware of the two most common WordPress hooks:
wp_footer(), which generally appear in the theme’s header and footer sections. These two hooks provide WordPress a location at which to execute various scripts and functions. For example, the
wp_head() hook is where WordPress generates a variety of
<link /> and
<script></script> elements, among other things.
Custom fields allow us to attach data to Posts or Pages that we can yank out and use at will in our templates. They are awesomely flexible and single-handedly allow WordPress to be used for about any CMS need. The fact that they can only be used on single Posts can be limiting in some circumstances. Sometimes you wish you could grab a custom value that you can control and is consistent globally, regardless of the current post. In this post we’ll look at a technique to do so.
Now that we have seen how to setup Tumblr-style posts, it would be nice to be able to segregate the Tumblr-posts category from the main feed into its own, separate feed. This would enable readers to subscribe exclusively to the Tumblr-posts feed and maybe display it in their sidebar or something.
Since posting the DiW tutorial on designing a Tumblelog theme for WordPress, several readers have asked for a tutorial on how to setup just the Tumblr/tumblelog-style post links …without having to implement the entire theme.
Since WordPress 2.8, we can target specific types of page views with CSS using the new
body_class() tag. Designed for use within the
body_class() outputs various class attributes according to the current type of page view. This makes it easy to apply page-specific styling such as current-page navigation highlighting and other nifty CSS tricks.
