WordPress搜索结果中排除指定页面和文章

有些时候你并不希望在搜索结果中出现一些私密的页面或是文章，要想排除于搜索结果之外很简单，在functions.php中加入：

function my_search_filter($query) {

if ( !$query->is_admin && $query->is_search) {

$query->set('post__not_in', array(ID,ID,ID,ID) ); }

return $query;

}

add_filter( 'pre_get_posts', 'my_search_filter' );

加粗的ID部分直接换为文章ID或是页面ID，顺带介绍下如何在后台直观地显示ID的方法：

add_filter('manage_posts_columns', 'wpjam_id_manage_posts_columns');
add_filter('manage_pages_columns', 'wpjam_id_manage_posts_columns');
function wpjam_id_manage_posts_columns($columns){
    $columns['post_id'] = 'ID';
    return $columns;
}

add_action('manage_posts_custom_column','wpjam_id_manage_posts_custom_column',10,2);
add_action('manage_pages_custom_column','wpjam_id_manage_posts_custom_column',10,2);
function wpjam_id_manage_posts_custom_column($column_name,$id){
    if ($column_name == 'post_id') {
        echo $id;
    }
}
