how to clear node custom field cache in drupal 7

Question

I'm using Drupal 7. i changed the value of one custom field from the site, with a sql query, but when i trying to edit the node in the admin, the value of the field was the old one.
what can i do to fix this issue, without clearing the cache from the admin panel?

Answer 1

You can try to clear cache after modification via SQL query:

 // Clear field cache
 cache_clear_all("field:node:$nid", 'cache_field');

Or for other entities

cache_clear_all("field:$entity_type:$entity->id", 'cache_field');
