Visualizzare articoli aggiornati nel widget
Ciao a tutti ; ho la necessità di visualizzare gli articoli aggiornati ma soltanto di una specifica categoria , ho trovato un plugin però visualizza tutte le attività svolte sul blog , pensavo se qualcuno saprebbe modificare il plugin in modo da mostrare solo gli articoli della categoria che interessa mostrare
Codice PHP:
<?php
/*
Plugin Name: Recently updated pages and posts
Plugin URI: http://www.tacticaltechnique.com/wordpress/wordpress-recently-updated-pages-or-posts/
Description: Creates a sidebar widget that displays a list of links to recently updated pages and posts.

// please send your code changes upstream to me
class recently_updated_widget extends WP_Widget {
function recently_updated_widget() {
// widget actual processes
parent::WP_Widget( /* Base ID */'recently_updated_widget', /* Name */'Recent updates', array( 'description' => 'Recently updated pages and posts' ) );
}
function form($instance) {
// outputs the options form on admin
// format options as valid html
$title = htmlspecialchars($instance['title'], ENT_QUOTES);
$post_count = htmlspecialchars($instance['post_count'], ENT_QUOTES);
$word_count = htmlspecialchars($instance['word_count'], ENT_QUOTES);
?>
<p>
