How to use wp_insert_post() to create a post whose post slug is equal to its ID

To create a post in WordPress using wp_insert_post() and set the post’s slug equal to its ID, you need to follow these steps:

1. Insert the post using wp_insert_post().
2. Once the post is created, retrieve its ID.
3. Update the slug of the post using wp_update_post().

Here is an example code:

// 1. Create the post
$post_data = array(
    'post_title'   => 'Post Title',
    'post_content' => 'Post content',
    'post_status'  => 'publish',  // or 'draft' depending on your needs
    'post_type'    => 'post',     // post type, can be 'page' or other if needed
);

$post_id = wp_insert_post($post_data);

// 2. Update the slug, setting it equal to the post ID
if ($post_id) {
    $post_slug = $post_id;  // Set slug equal to ID
    $post_data = array(
        'ID'        => $post_id,
        'post_name' => $post_slug,  // This is the slug
    );

    wp_update_post($post_data);
}

Explanation:

• First, we create the post using wp_insert_post() by passing data such as the title and content.
• After successfully creating the post, we retrieve its ID and update the post using wp_update_post(), setting the slug equal to the ID.

This way, the slug will automatically match the post’s ID.
