I am new to drupal 7, I have a question and hope to receive your helpful responses! :D
I've created a new content type named 'school', and create a custom 'city' field in it. After that, I create two new nodes of 'school', and their city are 'London' and 'Beijing'. How can I get a list of city of schools programmatically in Drupal 7?
Any help will be appreciated!
