How to check if a specific post meta isset/!emtpy during updating or publishing a post ( save_post() )?

1 Answer 1


I don't know what you want to do besides checking the meta so i'm gonna give a very basic example.

function bt_check_saved_post_meta ($post_id) {
    if (!empty(get_post_meta($post_id, 'some_meta', true))) {
        // do something here
add_action('save_post', 'bt_check_saved_post_meta');
