The generate_postdata() WordPress PHP function generates post data. This data is based on a WP_Post instance or Post ID/object that you provide.
Usage
Here’s a basic way to use the generate_postdata() function:
$post_id = 123; // Substitute with your actual post ID $post_data = generate_postdata($post_id); print_r($post_data);
In this example, we fetch the post data for a specific post by passing its ID to the function. The function returns an array containing the post data, which is then printed for viewing.
Parameters
- $post (WP_Post|object|int): Required. This is a WP_Post instance or Post ID/object. You use this to specify the post for which data is to be generated.

Loop Over Multiple Posts
This code fetches data for multiple posts in a loop.
$post_ids = [123, 124, 125]; // Your post IDs here
foreach ($post_ids as $post_id) {
$post_data = generate_postdata($post_id);
print_r($post_data);
}
Generating Data for the Latest Post
This code fetches data for the latest post.
$latest_post_id = get_posts(array('numberposts' => 1, 'post_status' => 'publish'))[0]->ID;
$post_data = generate_postdata($latest_post_id);
print_r($post_data);
Generating Data for a Post With a Specific Title
This code fetches data for a post with a specific title.
$title = "My Post Title"; // Your post title here $post_id = get_page_by_title($title, OBJECT, 'post')->ID; $post_data = generate_postdata($post_id); print_r($post_data);
Generating Data for a Post With a Specific Slug
This code fetches data for a post with a specific slug.
$slug = "my-post-slug"; // Your post slug here $post_id = get_page_by_path($slug, OBJECT, 'post')->ID; $post_data = generate_postdata($post_id); print_r($post_data);
In all these examples, generate_postdata() is used to generate post data, which is then printed for viewing. Make sure to replace placeholders with your actual post IDs, titles, or slugs.
