Wordpress hook for newly published post that can access to post metadata

Question

I need to do some actions only on newly published posts that requires post metadata.

I've tried many different hooks, but they all also trigger for other "events" like updating post, or if they trigger only on publish, metadata is empty or just has _edit_lock value inside.

auto-draft_to_publish hook triggers when I need it, but there is no post meta

add_action( 'auto-draft_to_publish', 'wpse120996_specific_post_status_transition' );


function wpse120996_specific_post_status_transition($post) { 
 if ($post->post_type != 'poruke') {
    return;
 }
 $post_meta = get_post_meta($post->ID);
 echo "<pre>";
    die(var_dump( $get_post_meta ));
 echo "</pre>";

}

transition_post_status works with the right status checks, but there is no post meta as well
```
'publish' === $new_status && 'publish' !== $old_status // right time,no post meta
```

publish_post it seems that this one doesn't even trigger for some reason

add_action( 'publish_post', 'myfunction' );
function myfunction($post) { 
 echo "<pre>";
    die(var_dump( 'PUBLISHED?' )); // this dump is nowhere to be found, I looked in network tab in debugger
 echo "</pre>";
}

save_post this one triggers as soon as "Add New" is pressed in a sidebar

I'm having a lot of problem with this and I have hard time beliving that something so "basic" would not be a feature in wordpress, but I didn't find anything helpful in my search so far.

Thanks in advance.

'publish_post' hook is deprecated, see adambrown.info/p/wp_hooks/hook/publish_post According to the link, publish_post only works when something of post-type: post is changed to publish status. Also, I am surprised die(var_dump('anything')) does anything for you, because var_dump() doesn't return anything. I would write var_dump('anything'); die(); but this is detail. It seems you have ran into a hard problem, I'm still working on it. — Snuwerd

First, see my comment below your opening post.

Second, in the 1. example you post, you are dumping $get_post_meta, but you meant to dump $post_meta.

I noticed $post has the post id number in it, not $post->ID, so I sent $post to get_post_meta.

This seemed to work for me:

add_action( 'publish_post', 'myfunction' );
function myfunction($post) {        
    print_r(get_post_meta($post)); die();
}

Be sure to test it while making a new post of type post, not other custom post types or pages, like the link in the comment explained ( https://adambrown.info/p/wp_hooks/hook/publish_post ) , you need to change the hook to something else to use it on other post types. So 'publish_events' for post type events.

UPDATE

My apologies, i see the resulting post_meta has little info in it:

Array ( [_edit_last] => Array ( [0] => 1 ) [_encloseme] => Array ( [0] => 1 ) )

Maybe it is time to do a feature request to Wordpress (for a post publish hook).
