I’m having an issue where I need to write a hook_update to remove a term (which the end-user deleted from the taxonomy) from nodes which have that term as a value in a taxonomy reference field with multiple values.
Because the end-user deleted the term, he now can’t save any node which has this term set.
Recoverable fatal error: Argument 2 passed to drupal_array_get_nested_value() must be of the type array, null given, called in /var/www/projectname/docroot/modules/field/field.form.inc on line 394 and defined in drupal_array_get_nested_value() (line 6814 from /var/www/projectname/docroot/includes/common.inc).
My Question is, how do I write this fix? I’m a front-end developer, so this is mostly new to me. I know I can put it in a .module file and that it has to start with “function hook_update_7XXX”
So I have to write a hook_update that gets all nodes who are using term 58 and then I should load these nodes? Followed by removing term 58, and then saving the nodes again.
