wordpress - get list of older post in wordpress

Question

Is there any function that can let me display older posts and post dates at the bottom of each post?The older posts must be in the same category. I searched on the internet but it seems that everyone just display one previous post only

Thank you very much

Answer 1

您可以使用 wp 过滤器来实现这一点

// Return posts from the last 30 days:
function filter_where( $where = '' ) {
// posts in the last 30 days
$where .= " AND post_date > '" . date('Y-m-d', strtotime('-30 days')) . "'";
return $where;
}

add_filter( 'posts_where', 'filter_where' );
$query = new WP_Query( $query_string );
remove_filter( 'posts_where', 'filter_where' );

或者

// Return posts for March 1 to March 15, 2010:
function filter_where( $where = '' ) {
// posts for March 1 to March 15, 2010
$where .= " AND post_date >= '2010-03-01' AND post_date < '2010-03-16'";
return $where;
}

add_filter( 'posts_where', 'filter_where' );
$query = new WP_Query( $query_string );
remove_filter( 'posts_where', 'filter_where' );

get_posts 函数允许您为帖子构建复杂的查询，您可以使用它来获取带有 order 和 category 参数的旧帖子。
