[XML-RPC] Post list of specific category.

Hello!

In file ‘xmlrpc.php’ we can find out useful functions.
Also here: link

What I want to do is to obtain (complete) list of post ID’s for given category Name or ID i.e. getPosts(4)

I have found two functions in xmlrmpc.php which we can use:
a) mw_getCategories and b) mw_getRecentPosts

For a) myBlog.getCategories() (I’m using C#)
We receive struct array of Categories which contains ‘Category Id’ , ‘Name’ etc.

1st question. How I can add to those structs, array of posts id’s which are in this category ?
(I can get post giving the post id, that’s why I want to obtain posts id’s of specific category)

For b) myBlog.getRecentPosts(20) where 20 is the numer of posts to receive

2nd question. How I can change this function to give category name/id and return all posts in that category id/name ?

Any ideas? Could someone help me with this?

Best Regards,
Matt

Example in files:

function mw_getCategories($args) {

		$this->escape($args);

		$blog_ID     = (int) $args[0];
		$username  = $args[1];
		$password   = $args[2];

		if ( !$user = $this->login($username, $password) ) {
			return $this->error;
		}

		if( !current_user_can( 'edit_posts' ) )
			return new IXR_Error( 401, __( 'Sorry, you must be able to edit posts on this blog in order to view categories.' ) );

		do_action('xmlrpc_call', 'metaWeblog.getCategories');

		$categories_struct = array();

		if ( $cats = get_categories('get=all') ) {
			foreach ( $cats as $cat ) {
				$struct['categoryId'] = $cat->term_id;
				$struct['parentId'] = $cat->parent;

add here i.e $struct[‘AllPosts’] which will be contains all posts ID’s in this category.

$struct['description'] = $cat->name;
				$struct['categoryDescription'] = $cat->description;
				$struct['categoryName'] = $cat->name;
				$struct['htmlUrl'] = esc_html(get_category_link($cat->term_id));
				$struct['rssUrl'] = esc_html(get_category_feed_link($cat->term_id, 'rss2'));

				$categories_struct[] = $struct;
			}
		}

		return $categories_struct;
	}

function mw_getRecentPosts($args) {

		$this->escape($args);

		$blog_ID     = (int) $args[0];
		$username  = $args[1];
		$password   = $args[2];
		$num_posts   = (int) $args[3];

		if ( !$user = $this->login($username, $password) ) {
			return $this->error;
		}

		do_action('xmlrpc_call', 'metaWeblog.getRecentPosts');

		$posts_list = wp_get_recent_posts($num_posts);

change num_posts to category_id and recive all posts in that category

if (!$posts_list) {
			return array( );
		}

			if ( !empty( $tags ) ) {
				foreach ( $tags as $tag ) {
					$tagnames[] = $tag->name;
				}
				$tagnames = implode( ', ', $tagnames );
			} else {
				$tagnames = '';
			}

			$post = get_extended($entry['post_content']);
			$link = post_permalink($entry['ID']);

			// Get the post author info.
			$author = get_userdata($entry['post_author']);

			$allow_comments = ('open' == $entry['comment_status']) ? 1 : 0;
			$allow_pings = ('open' == $entry['ping_status']) ? 1 : 0;

			// Consider future posts as published
			if( $entry['post_status'] === 'future' ) {
				$entry['post_status'] = 'publish';
			}

			$struct[] = array(
				'dateCreated' => new IXR_Date($post_date),
				'userid' => $entry['post_author'],
				'postid' => $entry['ID'],
				'description' => $post['main'],
				'title' => $entry['post_title'],
				'link' => $link,
				'permaLink' => $link,
				// commented out because no other tool seems to use this
				// 'content' => $entry['post_content'],
