It's becoming more and more common for blogs to feature certain posts at the top of the page. In this tutorial, we're going to show you how to implement this in WordPress. We'll be using the default theme, Kubrik, as our base theme, but it should be adaptable to most themes with some modification. There's very little code and featuring posts is simple.
What we're shooting for
We're going to be modifying the Kubrik theme that comes prepackaged in WordPress to be able to feature posts at the top of the page. This tutorial has only been tested on WordPress 2.5.x but it should work on the 2.3.x series as well. We're going to assume you're using 2.5.x or above. By the end of the tutorial, you'll have something like this:
Step 1 - Creating the default image
Before we do anything, go to the themes folder of your WordPress installation (wp-content/themes/) and make a backup of the "default" folder. This is the Kubrik theme we will be editing. The backup is in case you want to revert back to the original, unmodified theme.
First, we're going to make a default image in the event no featured post image is specified. Let's keep it sweet and simple for this tutorial. Open up your preferred image editor and create a 233x130px rectangle with 10px radius rounded corners. I made the background a white to grey radial gradient and put some text on top. This is what I have:
Save the image as "no-featured-image.jpg" in the "images" folder that is inside the "default" folder.
Step 2 - Add the PHP code
Now for the code. Open the "header.php" file inside the "default" folder. At the end of the file, you will see a div block and an hr tag like this:
<div id="header">
<div id="headerimg">
<h1><a href="<?php echo get_option('home'); ?>/"><?php bloginfo('name'); ?></a></h1>
<div class="description"><?php bloginfo('description'); ?></div>
</div>
</div>
<hr />
Between the ending div tag and the hr, insert the following code:
<div id="featured">
<ul id="carousel">
<?php
$featured_posts = get_posts('numberposts=3&category=1');
foreach( $featured_posts as $post ) {
$custom_image = get_post_custom_values('featured_image', $post->ID);
$image = $custom_image[0] ? $custom_image[0] : get_bloginfo("template_directory")."/images/no-featured-image.jpg";
printf('<li><a href="%s" title="%s"><img src="%s" alt="%s" /></a></li>', get_permalink($post->ID), $post->post_title, $image, $post->post_title);
}
?>
</ul>
<div class="clear"></div>
</div>
This code will output three images in an unordered list. Each image is a link to a featured post. We'll talk about how to configure the code after we add the CSS.
Step 3 - Style with CSS
Next we need to add some CSS styles. Open up the "style.css" file and put the following code below at the end of the file. All this does is float the list elements to the left and space them out evenly.
/* Featured Post Carousel */
#featured {
padding: 10px 10px 0 20px;
}
#carousel {
list-style: none;
margin: 0;
padding: 0;
}
#carousel li {
float: left;
padding: 0;
margin-right: 10px;
}
Step 4 - Understanding the code
Let's take a look at what the code we added does. Inside the container div (id="featured") we have an unordered list and some PHP code to generate list elements.
$featured_posts = get_posts('numberposts=3&category=<strong>1</strong>');
The first line shown above retrieves the post information using the get_posts() function and assigns the post data to the $featured_posts variable. The get_posts() function excepts a single parameter in the form of a query string similar to what you might see at the end of a URL (sans the initial question mark). The first parameter is "numberposts" which we've set to 3 for this tutorial. This parameter sets how many featured posts we will be showing. The second parameter is "category" which we've set to 1. The value of the "category" parameter should be the ID of the category you are using for your featured posts. You can find the ID of a category by going to the category management page and hovering your mouse over a category title. The status bar will show a link. The last number is the category ID.
The next line is a foreach loop that will loop through the posts we've retrieved using the get_posts() function. The first line inside the foreach loop retrieves the URL of the image using the get_post_custom_values() function and stores the URL in the $custom_image variable. The first parameter specifies the key of the custom value we're using, "featured_image". The second parameter specifies what post we're getting the value from.
$custom_image = get_post_custom_values('featured_image', $post->ID);
In the next line we do a quick check to see if an image was indeed specified. If no image was specified, we assign the $image variable the URL of the default image. If an image was specified, we use that.
$image = $custom_image[0] ? $custom_image[0] : get_bloginfo("template_directory")."/images/no-featured-image.jpg";
In the last line we actually output the list elements. Each element is an image that links to the featured post.
printf('<li><a href="%s" title="%s"><img src="%s" alt="%s" /></a></li>', get_permalink($post->ID), $post->post_title, $image, $post->post_title);
Step 5 - Creating Featured Posts
That's it! Now, whenever you want to feature a post, assign it to the featured category and create a custom value with a key of "featured_image" and a value of the image URL. Images should be 233x130px.

Is this turning into wordpresstuts? I’m not finding very applicable stuff here anymore because I don’t have wordpress.
( )Thomas Evan Lecklider July 21st
Is there any way you know of to extract an image from a post without having to create a custom field? WP spits out all images wrapped in paragraph tags, making it difficult to style separately from the rest of the paragraphs.
( )ilham saibi July 21st
nice, thanks.
( )Collis Ta'eed July 21st
@Braden: Hiho! Yes it has been a little WordPress centric lately! But don’t worry I’ve just loaded 3 non-WP posts into the system for the next three days
( )Andrei Constantin July 21st
I see no problem regarding wordpress, as long as there is a demand for it. Lots of people are using it and will do so in the future. I do however expect the non-wp tuts to come
( )Mark Abucayon July 22nd
That was very nice.. thank you for sharing this one.
( )Taote July 22nd
Why is the word carousel in the title? I don´t think it is a carousel. When I read it, I thought you would be able to click and navigate forward and backward, through more posts.
( )Ben Griffiths July 22nd
Interesting, thanks
Glad to see a few non WP posts are coming though!
( )Shane July 22nd
Yay for wordpress
thanks for posting.
( )Giuseppe July 22nd
Is putting the image URL in a special field the best solution? I think it would be better to fetch the image from the post uploads.
( )Tom July 22nd
Love your Wordpress tutorials, keep up the good job!

Nice tut, but wheres the “carousel”? All I see is static featured images.

I’m hoping for less Wordpress content as well. Sounds like it’s coming though, so I’m excited. I like what non-wordpress stuff is here so far.

I’ve been looking to do something like this with one of my blogs. Thanks for the tut, that should give me the motivation I need to actually get it done!
( )Connor July 23rd
Nice, though I was expecting something that maybe was animated…
( )Christopher Rogers July 24th
Awesome tutorial, exactly what I was looking for. But I can’t seem to get the article title to appear on the bottom of the image as you do in the demo. The images are loading fine. Can you tell me what to look for?
( )BeyondRandom July 25th
awesome stuff! Will have to get this going when I get home! Thanks
( )Scott Bernadot July 25th
Great Tutorial, but like another said, where is the carousel?
For those looking for a carousel, check out my site:

I am using it on my home page.
( )Gabe Diaz July 25th
Christopher Rogers - In the demo the section titles are actually over the background image in one jpg. So you have an image preview for the last 3 entries from a specific category, in this case category 1.
I guess they decided to call this a carousel in that it will auto update or push the newest post with image up into one of those 3 spots.
Instead of having 3 images up top for your last 3 posts and have summaries of the same posts underneath you can also edit your wordpress loop to offset the summaries in the body by 3(or any number you choose) so that you see your latest 3 images up to and the 4th with summary in the body of the site.
Giuseppe - You can edit the php to look for your custom field image in the upload folder within wordpress. Doing so you would be able to use the post upload feature built into wordpress and all you would need to put into the value field would be year/month/filename IE 2008/07/file.ext
Only drawback to uploading thumbs, or main images via the upload file(s) in WP2.6 is that all uploads via the uploads file(s) button link the uploads to the post. So if you were upload a gallery with 5 images and a thumbnail to a post, and inserted that gallery into your post you would see 6 images since your thumbnail is included. Easy work around…create a page solely for your thumbnails so that they are not included with any other galleries
Hope this helps!

it’s cool, thanks a lot!

Awesome post, this is just what I was looking for, in order to complete my new blog design. But, dude please tell me what editor you are using in the images above. It looks awesome. Let me know when you get a chance.
Thanks again!
Bryan
( )Jeff July 31st
I just had to do something like this for a client, and ended up contriving some convoluted solution having to do with categorization and tagging, outrageous PHP and so forth. This is FAR more elegant; I think I’m going to move to this model.
Thanks!
( )Bryan August 1st
Hey - I wrote a day or so ago, and never heard back. Just a few questions if you wouldn’t mind answering them?
1. Is there any way to, instead of using a default image when none is specified, use no image at all (so it’s just normal text with no image)?
2. What editor are you using in the images above?
Thanks,
Bryan
( )Phil August 1st
Hey, I would love to know if there was a trick out there that would do the thumbnails automatically, because I know myself. If I would add this, I’d do it for a month or so and then get too lazy to do thumbnails and thus not feature any posts anymore.
Somebody an idea or helping link? I googled, I failed.
( )James Lao August 1st
@Bryan
1. Yes. Instead of using the ternary operator to assign the $image variable, just test $custom_image[0] with an if statement and show an image on true and whatever text you want on false.
2. Not sure what you mean by ‘editor’. If you mean the admin style, it’s new in WordPress 2.6.x

Is there a way to rearrange the featured posts? It seems that they line up according to the date they were published?

Great tutorial! Now, how can we have the featured article advance automatically?
Essentially, I’d love to learn how to display one article (tagged as “Featured”) and, after a couple of seconds, have this automatically advance to the next article with the same tag.
( )jill December 21st
I agree with many of you - this is not a CAROUSEL. This is just placing 3 static images on top of a page.
I need something like this - but with the ability to scroll through more posts. Is there a quick fix to add some LEFT and RIGHT arrows, and add the ability to scroll through multiple posts?
( )blake December 21st
not a carousel. misleading.
( )Bob January 28th
( )Diego SA February 18th
Well, carousel or not, it’s nice!
Not a full interactive carousel but it’s cool.
Maybe modifying a thumbnail plugin is a way to create a full interactive carousel…
( )Joe February 19th
This is very helpful. Thank you, much appreciated. I am having one issue, that I thought you might have some advice on:
I have it set to display one post. For some reason, it keeps replicating the same image, three times in a row. Regardless of the fact, that I have it set to “1″.
Know why it might be doing this?
( )Eric March 12th
This is really nice

Nice tutorial, thanks! After much hammering to get it fit into our template, I managed to get it to work in our prototype site, but I still need some way to integrate that with qTranslate.
Now, i have a question: on your example, one can see some text on a semi-transparent layer. Is this supposed to be part of the image or does it get added automagically by the code? I’m guessing the latter, but I’d appreciate confirmation.
It would be very cool to have this as a plug-in, with 1) image auto-resize, 2) text layer.
Many thanks in advance!
( )Morgan Daly March 22nd
Hello,
I would like to be able to do a similar thing on a project soon but was wondering if it was possible to do by pulling in the title of the post automatically and maybe pulling in the already uploaded thumbnail without using custom fields?
Thanks
