   Hi all,
   I have placed the following code in a template file

   __update_post_meta( $the_post_id, 'user_id', $user_id );

   but each time the code executes there's an error occuring:

   Fatal error: Call to undefined function __update_post_meta() in /home/public_html/wp-content/themes/mytheme/register.php on line 133

   I suppose that I have to import some kind of wordpress file here, but I don't know what that should be. Any suggestions?

   try to use the function name without the two underline characters;

   update_post_meta()

   That's the way I've been using this function since now, and it's been working fine.... But I was silly enough not thing to test the function after removing the underline. Thanks a lot!
