Wordpress: Hide protected post on Recent Post widget

Istvan — Fri, 28 Aug 2009 19:15:45 +0000

I am using the WP Hide Post and I didn’t like that the password protected posts are displayed on the front Recent Post section.

I added 2 small php code and now there are no protected posts on Recent Post.

The way is:

1. Change wp-includes/default-widgets.php file

^?View Code PHP

$r = new WP_Query(array('showposts' =&gt; $number, 'nopaging' =&gt; 0, 'post_status' =&gt; 'publish', 'caller_get_posts' =&gt; 1));

^?View Code PHP

$r = new WP_Query(array('showposts' =&gt; $number, 'nopaging' =&gt; 0, 'post_status' =&gt; 'publish', 'caller_get_posts' =&gt; 1, 'post_password'=&gt;'hide' ));

2. Change wp-includes/query.php file

^?View Code PHP

if ( !isset($q['caller_get_posts']) )
    $q['caller_get_posts'] = false;

^?View Code PHP

if (!current_user_can('manage_options') &amp;&amp; isset($q['post_password'])=='hide')
    $where .= " AND ($wpdb->posts.post_password = '') ";
 
if ( !isset($q['caller_get_posts']) )
    $q['caller_get_posts'] = false;
