In my functions.php I have:

 global $wpdb;
   array('post_content' => $newcontent), 
   array('ID' => $post_id) 

this code updates the post_content in the WP DB with my $newcontent when I publish a post. In fact I can see the modified content inside the DB and of course I can see it with:

 echo get_post_field('post_content', $post_id);

The issue is that (after publish and update) the post editor continues to show the old content! In a few words... I need a way to force the editor to show the $newcontent, the one stored into the DB (after publish). Any ideas?

  • P.S. Of course if I exit from the post and then I go there again, I see the new content! – Augusto Feb 24 '16 at 16:44

    Ah you want a live update? That functionality isn't present in WordPress Core, you'll need to build it yourself. Also, instead of changing the database directly, use wp_update_post so that the necessary caches and actions and filters are called, always avoid using direct database queries – Tom J Nowell Feb 24 '16 at 17:33

try wp update post function:

// Update post 37 for example
  $my_post = array(
  'ID'           => 37,
  'post_title'   => 'This is the post title.',
  'post_content' => 'This is the updated content.',

// Update the post into the database
  wp_update_post( $my_post );


  • Yes, it was the wp_update_post!! Thank you Tom, Prosti and thank you Shady Alset you save me!! – Augusto Feb 24 '16 at 22:32

I am not quite sure what is your scenario, but I think you need to refresh the WordPress editor. If you did that try to update the post since it is cached. https://codex.wordpress.org/Function_Reference/wp_update_post
