How to Randomly Display 4 Categories with 3 Latest Posts in WordPress: A Comprehensive Guide
As a WordPress website owner, you're always looking for ways to engage your audience and showcase your content in an eye-catching and dynamic manner. One feature that can really help with this is the ability to display a random selection of categories, each with their three latest posts.
In the past, WordPress developers may have used a code snippet like this:
$cat_args = array(
'orderby' => 'rand',
'order' => 'ASC'
);
However, this approach has some limitations and may not be the most efficient way to achieve the desired result. In this comprehensive guide, we'll explore a better method to randomly display 4 categories with 3 latest posts on your WordPress website.
Understanding the Problem
The code snippet mentioned earlier works well for displaying posts, but it doesn't handle categories in the same way. When you try to use this code to retrieve random categories, it may not produce the desired outcome. Additionally, the get_categories()
function in WordPress retrieves all categories, which can become cumbersome if you have a large number of them on your website.
To address these issues, we'll use a different approach that utilizes the power of the WordPress get_categories()
function and the shuffle()
function in PHP to achieve the desired result.
Step 1: Retrieve the Categories
First, let's get the list of categories on your WordPress website. We'll do this using the get_categories()
function:
$categories = get_categories();
This line of code will retrieve all the categories on your website and store them in the $categories
variable.
Step 2: Shuffle the Categories
Now, we need to randomly shuffle the order of the categories. We can use the built-in shuffle()
function in PHP to achieve this:
shuffle($categories);
This will randomize the order of the categories in the $categories
variable.
Step 3: Limit the Number of Categories
By default, the get_categories()
function will retrieve all the categories on your website. However, we only want to display 4 random categories. To achieve this, we'll use the array_slice()
function to limit the number of categories:
$random_categories = array_slice($categories, 0, 4);
This line of code will take the first 4 elements from the $categories
array and store them in the $random_categories
variable.
Step 4: Retrieve the Latest Posts for Each Category
Now that we have the 4 random categories, we need to fetch the 3 latest posts for each of them. We can use the get_posts()
function to achieve this:
foreach ($random_categories as $category) {
$posts = get_posts(array(
'category' => $category->term_id,
'numberposts' => 3,
'order' => 'DESC',
'orderby' => 'date'
));
$category_posts[$category->slug] = $posts;
}
This code loop through the $random_categories
array, and for each category, it retrieves the 3 latest posts using the get_posts()
function. The posts are then stored in the $category_posts
array, with the category slug as the key.

Step 5: Display the Categories and Posts
Now that we have the 4 random categories and their 3 latest posts, we can start displaying them on your website. Here's an example of how you can do this:
<div class="random-categories">
<h2>Check Out These Random Categories</h2>
<?php foreach ($random_categories as $category) { ?>
<div class="category-container">
<h3><a href="<?php echo get_category_link($category->term_id); ?>"><?php echo $category->name; ?></a></h3>
<div class="posts">
<?php foreach ($category_posts[$category->slug] as $post) { ?>
<div class="post">
<a href="<?php echo get_the_permalink($post->ID); ?>">
<?php echo get_the_title($post->ID); ?>
</a>
</div>
<?php } ?>
</div>
</div>
<?php } ?>
</div>
This code will create a section on your website with 4 random categories, each displaying their 3 latest posts. The category names are linked to their respective category archives, and the post titles are linked to their individual post pages.
You can further customize the HTML and CSS to match the design of your WordPress website, making the section visually appealing and consistent with your brand.
Advantages of this Approach
The method we've outlined in this guide has several advantages over the previous code snippet:
-
Randomization of Categories: By using the shuffle()
function, we ensure that the categories displayed are truly random, providing a more dynamic and engaging experience for your website visitors.
-
Limiting the Number of Categories: By using the array_slice()
function, we only display 4 random categories, preventing the section from becoming cluttered or overwhelming.
-
Retrieving the Latest Posts: The get_posts()
function allows us to fetch the 3 latest posts for each category, ensuring that the content is up-to-date and relevant.
-
Flexibility and Customization: The code can be easily adapted to fit your specific website's design and layout, making it a versatile solution for WordPress websites of all sizes.
Conclusion
In this comprehensive guide, we've explored a better way to randomly display 4 categories with 3 latest posts on your WordPress website. By using the get_categories()
, shuffle()
, and get_posts()
functions, we've created a dynamic and engaging section that will captivate your website visitors and showcase your content in an effective manner.
Remember, the success of your website is not just about the content you create, but also how you present it to your audience. By implementing this solution, you're taking a step towards a more engaging and user-friendly WordPress website.
