How to access the post meta of a post that has just been published?

by

I am using the hook publish_post to run my code where I need the post meta of the just published post. But the post meta value I am looking for is somehow not available at this point of execution. On checking the wp_postmeta table, I found that my meta key value hasn’t been created yet. Also, I want this to work for a post published for the first time. Is there any other hook that can give me access to it?

function push_notification($post_id) 
{ 
    $ref_ids = get_post_meta($post_id,'ref_id'); 

    if($ref_ids) 
    { 
        //my code goes here 
    } 
} 

add_action('publish_post','push_notification');

Solved it! Used save_post to run push_notification() as well as to run the function save_post_meta() that saves my post meta. The problem occurred coz push_notification() gets fired before save_post_meta() due to which the meta wasn’t being saved and therefore it remained inaccessible. Just changed priorities of the functions to make it work like so :

function push_notification($post_id) 
{ 
  $ref_ids = get_post_meta($post_id,'ref_id'); 

  if($ref_ids) 
  { 
    //my code goes here 
   } 
} 
add_action('save_post','push_notification',11,1);

function save_post_meta($post_id,$post)
{
   //check for nonces and current user capabilities

   $ref_id = sanitize_html_class($_POST['ref_id']);
   update_post_meta($post_id,'ref_id',$ref_id);
}
add_action('save_post','save_post_meta',10,2);

function no_notification()
{
  remove_action('save_post','push_notification',11,1);
}
add_action('publish_to_publish','no_notification');

The last function no_notification() makes sure that push_notification() gets fired only when a post is first created and not for updates.
