How can I pass $post object to 'save_post' add_action?

Question

I have several functions that are called from inside a save_post function. However, all of the functions that use the $post object are returning incorrect values because it appears that the default value being passed to save_post is the post ID rather than the post object.

How can I pass the post object to the save_post function in addition to the post ID?

add_action('save_post', 'my_save_function');

Answer 1

Do:

add_action('save_post', 'my_save_function', 10, 2);

And the $post object will be passed as second argument to your function:

function my_save_function($post_ID, $post) {

Answer 2

Use get_post($post_id)
