get category of current post wordpress with code examples

WordPress is a popular content management system (CMS) that powers millions of websites across the world. One of the most important features of WordPress is its ability to categorize posts. Categories help users navigate through your blog more easily and find related content. If you’re a developer looking to get the category of the current post in WordPress, you’ve come to the right place. In this article, we will walk you through the process of getting the category of the current post in WordPress with code examples.

What Are Categories in WordPress?

Categories in WordPress are a way to group posts together based on similar topics. They help organize your content, making it easier to browse and discover related posts. You can create as many categories as you want and assign posts to them. For example, if you run a food blog, you might have categories such as “Recipes”, “Restaurant Reviews”, “Cooking Tips”, and so on. This makes it easier for your readers to find the type of content they’re looking for.

How to Get the Category of the Current Post in WordPress

Getting the category of the current post in WordPress requires a few lines of code. There are two main methods to do this, both of which make use of the WordPress function get_the_category().

Method 1: Using get_the_category()

This method involves calling the get_the_category() function and passing in the post ID as an argument. Here’s what the code looks like:

$category = get_the_category( $post_id );

This function returns an array of category objects for the current post. Each category object contains the category ID, name, slug, and other properties. To get the name of the category, simply access the name property of the first category object in the array:

$category_name = $category[0]->name;

Here’s the full code to get the category of the current post using get_the_category():

$post_id = get_the_ID();
$category = get_the_category( $post_id );
$category_name = $category[0]->name;
echo $category_name;

Method 2: Using wp_get_post_categories()

The second method to get the category of the current post is to use the wp_get_post_categories() function. This function takes in the post ID as an argument and returns an array of category IDs for the post. Here’s what the code looks like:

$categories = wp_get_post_categories( $post_id );

To get the name of the category, you first need to get the category object using the get_category() function. This function takes in the category ID as an argument and returns the category object:

$category_obj = get_category( $categories[0] );
$category_name = $category_obj->name;

Here’s the full code to get the category of the current post using wp_get_post_categories():

$post_id = get_the_ID();
$categories = wp_get_post_categories( $post_id );
$category_obj = get_category( $categories[0] );
$category_name = $category_obj->name;
echo $category_name;

Wrap Up

Categorizing your posts is an important aspect of managing your WordPress site. Categories make it easy for your readers to find related content and navigate through your site. Getting the category of the current post in WordPress is a straightforward process that involves using one of two functions: get_the_category() or wp_get_post_categories(). With the code examples provided in this article, you should now have a better understanding of how to get the category of the current post in WordPress.

here are some additional details about the topics covered in the article:

Categories in WordPress:

As mentioned, categories in WordPress are a way to group posts together based on similar topics. They are also hierarchical, which means you can create subcategories within a category for even more organization. For example, you might have a category called “Travel” and subcategories within it for “Europe”, “Asia”, and “South America”.

To create and manage categories in WordPress, go to the Posts menu in your WordPress dashboard and select Categories. From there, you can add, edit, and delete categories as needed.

get_the_category():

The get_the_category() function is a built-in WordPress function that retrieves the categories for a specific post. It returns an array of category objects, each with properties such as ID, name, slug, and description.

In the code example provided, we pass the $post_id variable to the function, which gets the ID of the current post using get_the_ID(). We then access the name property of the first category object in the array to get the name of the category.

wp_get_post_categories():

The wp_get_post_categories() function is another built-in WordPress function that retrieves the categories for a specific post. It works slightly differently than get_the_category(), as it returns an array of category IDs, rather than category objects.

To get the name of the category using wp_get_post_categories(), we need to pass the category ID to the get_category() function to retrieve the category object. We then access the name property of that object to get the name of the category.

It’s worth noting that both get_the_category() and wp_get_post_categories() only retrieve the categories for a single post. If you want to retrieve all categories (or a specific category) for multiple posts, you’ll need to use a different function, such as get_categories().

Overall, getting the category of the current post in WordPress is a relatively simple process, but it’s an important one for organizing and displaying your content effectively. By using either get_the_category() or wp_get_post_categories(), you can easily retrieve the category of any post on your WordPress site.
