In a theme I'm developing, I need to link to the source post when the post has been stored using XMLRPC. That implies that every time Wordpress asks for a permalink (using get_permalink()) the theme will return a previously saved link. That's accomplished by adding a new filter:

add_action('the_permalink', 'filterPermalink'); function filterPermalink($url) { $permalink = get_previously_saved_permalink(get_the_ID()); return $permalink? $permalink : $url; }

That's not the problem (by the moment). The problem is, how to make the same with the metaWeblog.newPost function.

I've already tried something like this:

add_filter('xmlrpc_methods','xml_rpc_functions_to_add'); function xml_rpc_functions_to_add($args) { $args['metaWeblog.newPost'] = 'add_permalink'; return $args; } function add_permalink($args) { // Do it }

What I need is to know how to call the previous 'metaWeblog.newPost' from 'add_permalink'.

  • You're trying to do two things. Your working code calls get_previously_saved_permalink() to replace the standard link with one saved elsewhere (post meta perhaps). But now you're trying to hook in to save a different permalink via XMLRPC? Commented May 21, 2012 at 21:10
  • The idea is simple: assign a source link (given by XMLRPC protocol) to each post so the permalink filter could read and use it. Now I've get add_permalink to work, I've edited the question removing the text where I said that wordpress was not executing this part. Commented May 22, 2012 at 8:49

From look at source metaWeblog.newPost seems to be processed in wp_xmlrpc_server->mw_newPost() method.

At the end of this method there is following hook call:

do_action( 'xmlrpc_call_success_mw_newPost', $post_ID, $args );

which seems to be very fitting to process and save any additional information for post that have just been created by its ID provided.
