I've created the field "Attending" that is attached to the user profile.
I have created a form with one checkbox element; when submitted, I've confirmed that the attending_fielddatabase is being updated with the current value (0 or 1), but when I view the user profile through the UI, the updated value isn't being displayed.

The submit handler I am using is the following:

function rsvp_aform_submit($form, &$form_state) {
  global $user;
  db_query("UPDATE {field_data_field_attending} SET field_attending_value = :val WHERE entity_id = :eid", array(':val' => $form_state['values']['rsvp'], ':eid' => $user->uid));
  drupal_set_message(t('Your form has been saved.'));
}

Do you have any idea?

I think that's the caching. First try to clear the cache manually. If that helps you should use cache_clear_all() to clear the corresponding cache tables (e.g. cache_content, cache_views_data) after you update the db.

  • In fact, what worked for me was drupal_flush_all_caches().

  • ok, but it's a little overkill to clear all caches and rebuild the theme_registry every time this form is submitted. thats simply not necessary and could result in performance shortage.

  • Hmm.. I'll need to dig into it then - cache_clear_all() didn't do the trick..

  • have you passed the $table parameter? check which cache table you need to clear. maybe just take a look inside your db to find the guilty ones and try. take a look at api for more info on how to use cache_clear_all().
