CalinSoft.net me preguntaba donde se encontraba el fichero wp-json.php que uso para servir un objeto json como método de sindicación, lo he encontrado aqui y lo pongo a vuestra disposición para que podais utilizar este sistema para ofrecer más opciones de sindicación.
<?php
if (empty($wp)) {
require_once('wp-config.php');
wp('feed=rss2');
}
function json_cats() {
$categories = get_the_category();
$the_list = '';
foreach ( (array) $categories as $category ) {
$category->cat_name = convert_chars($category->cat_name);
$cats[] = $category->cat_name;
}
$the_list = '"' . implode('","', $cats) . '"';
return apply_filters('the_category_json', $the_list, $type);
}
function json_safe_text($t) {
return str_replace(
array("\",'"', "n", "t", "r"),
array("\\", '\"', "\n", "\t", "\r"),
$t);
}
//header('Content-type: application/json; charset=' . get_option('blog_charset'), true);
header('Content-type: text/javascript; charset=' . get_option('blog_charset'), true);
$more = 1;
global $wp_query;
$total_posts = count($wp_query->posts);
?>/*

Para aprovecharte de este sistema, guarda este código en el fichero wp-json.php y ubícalo en el directorio raiz de tu WordPress.
