The save_post action hook fires after a post is saved: every time, even for autosaves. If you look at the reference for save_post, you’ll see that the callback receives three parameters: the first is an integer $post_ID, the second is a WP_Post object $post, and the third is a boolean $update. None of the parameters … Read more
I suppose a quick and dirty way to achieve what you want is to clear the entire site cache, something like this: function clear_rocket_cache_on_post_save() { rocket_clean_domain(); } add_action( ‘save_post’, ‘clear_rocket_cache_on_post_save’ ); Otherwise you’ll need to do a query to get the matching post, something like this should work: function clear_rocket_cache_on_post_save( $post_id ) { // $result_id … Read more

A quick glance at the … Read more
It looks to me like save_post doesn’t work the way you currently have your add_action. According to the Codex, you need to run your function on save_post and check the post type in the function. function get_film_data( $post_id ) { if ( get_post_type($post_id) == ‘film’ ) { // If this is just a revision, don’t … Read more
When you choose “Your CPT > Add New”, WP calls get_default_post_to_edit(), which actually creates an “empty” post (with ‘post_status’ => ‘auto-draft’) and then calls wp_insert_post(). This is what is causing your save_datasheet_meta() function to be called before you think it should. Hence, generally you should add some additional sanity checks to the beginning of any … Read more
