Update Published Post hook

Description

The action hook is executed at the end of “update published content” of a page. This typically happens when you are signing off the revised post at the end of the workflow.

Use this hook to copy over data from the revised post to the already published post.

Usage

add_action('owf_update_published_post', 'update_post_meta_info', 10, 2);

Parameters

• $original_page_id – ID of the published/original page
• $revised_page- revised page to copy the data from

Example

add_action('owf_update_published_post', 'update_post_meta_info', 10, 2);

function update_post_meta_info($original_post_id, $revised_post) {
   	$post_meta_keys = get_post_custom_keys($revised_post->ID);
   	if (empty($post_meta_keys)) return;

   	foreach ($post_meta_keys as $meta_key) {
   	   $meta_key_trim = trim($meta_key);
         if ( '_' == $meta_key_trim{0} || strpos($meta_key_trim,'oasis') !== false ) //ignore keys like _edit_last, _edit_lock, oasis
            continue;
   		$revised_meta_values = get_post_custom_values($meta_key, $revised_post->ID);
   		$original_meta_values = get_post_custom_values($meta_key, $original_post_id);

   		// find the bigger array of the two
   		$meta_values_count = count($revised_meta_values) > count($original_meta_values) ? count($revised_meta_values) : count($original_meta_values);

   		// loop through the meta values to find what's added, modified and deleted.
   		for($i = 0; $i < $meta_values_count; $i++) {
   		   $new_meta_value = "";
   		   // delete if the revised post doesn't have that key
   		   if (count($revised_meta_values) > $i+1) {
   			   $new_meta_value = maybe_unserialize($revised_meta_values[$i]);
   		   }
   		   else {
   		      $old_meta_value = maybe_unserialize($original_meta_values[$i]);
   		      delete_post_meta($original_post_id, $meta_key, $old_meta_value);
   		      continue;
   		   }

   			// old meta values got updated, so simply update it
   			if (count($original_meta_values) > $i+1) {
   			   $old_meta_value = maybe_unserialize($original_meta_values[$i]);
   			   update_post_meta($original_post_id, $meta_key, $new_meta_value, $old_meta_value);
   			}

   			// new meta values got added, so add it
   			if (count($original_meta_values) < $i+1) {
   			   add_post_meta($original_post_id, $meta_key, $new_meta_value);
   			}

   		}
   	}
   }
