How to Get All Posts By Category In WordPress?

10 minutes read

To retrieve all posts by a specific category in WordPress, you can use the built-in function get_posts() along with the WP_Query class. Here's how you can accomplish this:


First, you need to find the category ID for the desired category. You can do this by navigating to the "Posts" section in your WordPress dashboard, clicking on "Categories," and locating the desired category. Note down its ID.


Once you have the category ID, you can use the following code to retrieve all posts within that category:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
$args = array(
    'category' => {CATEGORY_ID},
    'posts_per_page' => -1, // Retrieves all posts (you can adjust this value if needed)
    'post_type' => 'post',
    'post_status' => 'publish',
);

$posts = get_posts($args);

foreach ($posts as $post) {
    // Output post details as per your requirement
    echo '<h2>' . $post->post_title . '</h2>';
    echo '<p>' . $post->post_content . '</p>';
}


Make sure to replace {CATEGORY_ID} with the actual ID of the desired category.


The code above constructs an array of arguments ($args) to customize the query. In this case, we specify the category, set the number of posts to display to -1 (which means unlimited), and specify that we are querying posts with a post_type of 'post' and a post_status of 'publish'. Feel free to modify the arguments as per your requirements.


Next, the get_posts() function is called with the provided arguments, which retrieves an array of posts that match the criteria. Lastly, we iterate through each post in the resulting array using a foreach loop and output the desired post details (post_title and post_content) as per your specific needs within the loop.


By implementing this code, you will be able to retrieve and display all posts within a specific category in WordPress.
