在循环外调用WordPress某文章评论数
function add_comment_count_to_posts() {
global $wpdb, $post;
$id = $post->ID;// 文章ID
$comment_count = $wpdb->get_var( "SELECT comment_count FROM $wpdb->posts WHERE post_status = 'publish' AND ID = $id" );// 获取文章评论数
$comment_status = $wpdb->get_var( "SELECT comment_status FROM $wpdb->posts WHERE ID = $id" );// 文章是否开启了评论
$html = '<div class="comment-popup">';
$html .= '<span>';
$count = '';
if( $comment_status == 'open' ) {
$count = $comment_count;
} else {
$count = '评论关闭';
}
$html .= $count . '</span></div>';
return $html;
}
获取某文章最新一条评论日期:
$comment_args = array(
'post_id' => get_the_ID(),
'number' => 1,
);
$latest_comment = get_comments($comment_args);
echo $latest_comment[0]->comment_date;
