How to get WordPress posts from a single category using XML-RPC

Question

I\'m developing an Android app for a WordPress site. I\'m using XMLRPC to fetch posts from the server and list them in the app.

Since the XMLRPC client I use for And

You'll create a plugin that implements a custom function as shown in Custom XML-RPC Methods in WordPress and install it on the target site.

escape( $args );

    $blog_ID     = (int) $args[0];
    $username  = $args[1];
    $password   = $args[2];
    $post_type  = $args[3];
    $category = $args[4];
    $numberposts = $args[5];
    $extra = $args[6];

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

    $category_int = (int) $category;

    if( !empty( $category_int ) ) {
        $category_call = 'cat';
    } else {
        $category_call = 'category_name';
    }

    $post_args = array(
        'numberposts' => $numberposts,
        'posts_per_page' => $numberposts,
        $category_call => $category,
        'post_type' => $post_type,
        'post_status' => 'any'
    );
    if( is_array( $extra ) )
        $post_args = array_merge( $post_args, $extra );

    $posts_list = get_posts( $post_args );

    if ( !$posts_list ) {
        $wp_xmlrpc_server->error = new IXR_Error(500, __('Either there are no posts, or something went wrong.'));
        return $wp_xmlrpc_server->error;
    } else {
        return $posts_list;
    }
}

The following is a test file in PHP (I don't know Java):

%s

', print_r( $xml->params->param->value->array->data->value, true ) ); } /** * XML-RPC call */ function query_last_posts( $methodName, $url, $parameters ) { $request = xmlrpc_encode_request( $methodName, $parameters ); $ch = curl_init(); curl_setopt( $ch, CURLOPT_POSTFIELDS, $request ); curl_setopt( $ch, CURLOPT_URL, $url ); curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 ); curl_setopt( $ch, CURLOPT_TIMEOUT, 1 ); $results = curl_exec( $ch ); curl_close( $ch ); return $results; } $blog_id = 1; $user = 'username'; $pass = 'password'; $type = 'post'; $category = 1; // ID or category name $num_posts = 1; $args = array( $blog_id, $user, $pass, $type, $category, $num_posts, null ); $response = query_last_posts( 'b5f.getPosts', 'http://EXAMPLE.COM/xmlrpc.php', $args ); print_xml_node( $response );
