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');

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) {

@sorich: I'm getting an different (and incorrect) value for $post->ID echo inside the "my_save_function" than when its echo'd outside that function. Any ideas? – Scott B Nov 1 '10 at 17:14
Do you mean echo $post_ID and echo $post->ID return different results? – sorich87 Nov 1 '10 at 17:19
Every time I test, the value of $post_ID, it gets incremented by one. Its as if this were a draft version ID incrementing. Any ideas? – Scott B Nov 1 '10 at 17:21
$post_ID and $post->ID are the same. However, the value being returned is in the 300's (increments by one each time i click "Publish" to test). My post id should be 176 – Scott B Nov 1 '10 at 17:24
I am not sure, but I think it has something to do with the post revision. Are the values of $post->post_content and $post->post_title correct? – sorich87 Nov 1 '10 at 17:33

Use get_post($post_id)
