從wordpress頁面排除受密碼保護的帖子

Question

任何人都可以解釋我如何更改以下代碼以排除受密碼保護的帖子嗎？我知道我可以在while語句中使用if語句，但我想從WP_Query點中排除它們。

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

Answer 1

你可以把它用post_where過濾器發生，您執行查詢之前：

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; 
}
