Wordpress API Get Posts by category

问题

Is it possible to get all posts by category?

http://codex.wordpress.org/XML-RPC_WordPress_API/Posts

回答1:

I managed to get this working in the end by using the optional filters parameter. According to the documentation these are the following accepted filter parameters.

struct filter: Optional. string post_type string post_status int number int offset string orderby string order

Out of curiousity I sent over a 'category' filter by adding the following to class-wp-xmlrpc-server.php under the getposts method

if(isset($filter['category']))
     $query['category'] = absint($filter['category']);

before the wp_get_recent_posts{$query); method is called

and it worked! It seems like Wordpress have left out a few filter parameters from their documentation.

You can also send over a search filter by passing over 's' as the filter

$query['s'] = $filter['s'];

It doesn't look like there is a way to filter beforehand. You may need to run the API call and filter afterwards.

You'd probably be best off asking on the stackexchange wordpress site though.

It's quite easy after all. From this WPSE answer, we learn that we can extend the XML-RPC methods and create our own my.getPosts, like show by this William P. Davis' extension code on GitHub _{^{- - fork}}.

Basically, create a plugin with the following code and adapt the arguments accepted to produce the output:

add_filter( 'xmlrpc_methods', 'add_my_xmlrpc_methods' );

function add_my_xmlrpc_methods( $methods ) {
    $methods['bdn.getPosts'] = 'bdn_xmlrpc_get_posts';
    return $methods;
}

function bdn_xmlrpc_get_posts( $args ) {
    # Adapt wp.getPosts to your needs

}
