Little-known hack to update all posts or pages in WordPress by code

Sometimes you need to open and update all pages of a WordPress website to get changes to take place.

This might be due to a newly added plugin, or simply a re-organisation of the theme architecture or layers.

If your site has a lot of pages, this can become a hideous task.

With the help of a small function, we can achieve this programmatically, just change the post_type to match what you want to update (post, page or custom post type).

Where do I add this code in WordPress?

Just add this snippet on the function.php of the theme you are using.

If you are unsure on how-to, this is an excellent guide from WP Beginner.

IMPORTANT! Don’t forget to remove the code once the update has been completed!

// Update all post

function update_all_posts() {
    $args = array(
        'post_type' => 'page',
        'numberposts' => -1
    );
    $all_posts = get_posts($args);
    foreach ($all_posts as $single_post){
        $single_post->post_title = $single_post->post_title.'';
        wp_update_post( $single_post );
    }
}
add_action( 'wp_loaded', 'update_all_posts' );
