从wordpress页面排除受密码保护的帖子

Question

任何人都可以解释我如何更改以下代码以排除受密码保护的帖子吗？我知道我可以在while语句中使用if语句，但我想从WP_Query点中排除它们。

$pq = new WP_Query(array('post_type' => $ptype, 'showposts' => $pshow)); 

Answer 1

你可以把它用post_where过滤器发生，您执行查询之前：

function getNonPasswordedPosts(){  
    // Add the filter to exclude passworded posts 
    add_filter('posts_where', 'excludePassworded'); 

    // Query for the posts 
    $pq = new WP_Query(array('post_type' => $ptype, 'showposts' => $pshow)); 

    // Remove the filter so that other WP queries don't exclude passworded posts 
    remove_filter('posts_where', 'excludePassworded'); 

    // iterate over returned posts and do fancy stuff  
} 

function excludePassworded($where) { 
    $where .= " AND post_password = '' "; 
    return $where; 
}
