The hook also fires when clicking on the “Add New” option for the custom post type, as it creates the draft in the DB, and when calling the
wp_update_postfunction as well.Feedback
You can know whether the hook fired from the “Add New” option by checking the post status:
if ( $post->post_status == "auto-draft" ) { return; }It’s also good to note that this hook is also called when trashing a post or restoring it from trash. — By Benjamin Intal —
It’s kind of sad that this more explicit action fires before the less explicit ‘save_post’ action.
This means if a 3rd party plugin does something using ‘save_post’ you need to use ‘save_post’ to override it too.
// someone else's code... add_action( 'save_post', 'wpdocs_do_something_custom', 15 ); // try to override with CPT action - DOES NOT WORK add_action( 'save_post_third_party_cpt', 'wpdocs_override_something_custom', 20, 2 ); // you must do this to override add_action( 'save_post', 'wpdocs_override_something_custom', 20, 2 ); function override_something_custom( $post_id, $post ) { // bail out if this is an autosave if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) { return; } // bail out if this is not an event item if ( 'third_party_cpt' !== $post->post_type ) { return; } // ... do override stuff }Expand full source codeCollapse full source code
Notify your newsletter subscribers when a new book (custom post) is added-
add_action( 'save_post_book', 'wpdocs_notify_subscribers', 10, 3 ); function wpdocs_notify_subscribers( $post_id, $post, $update ) { // If an old book is being updated, exit if ( $update ) { return; } $subscribers = array( 'john@doe.com', 'jane@doe.com', 'someone@else.com' ); // list of your subscribers $subject = 'A new book has beed added!'; $message = sprintf( 'We\'ve added a new book, %s. Click <a href="%s">here</a> to see the book', get_the_title( $post ), get_permalink( $post ) ); wp_mail( $subscribers, $subject, $message ); }Expand full source codeCollapse full source code
