访问数组中的值/Object？

Question

正在尝试遍历一组类别并显示每个类别中最新 post 的标题。

  $feed_sources = array('goose-creek','sleepy-creek','fobr');
  foreach ($feed_sources as $feed) {
    $args = array('category_name' => $feed, 'posts_per_page' => 1);
    $show = get_posts($args); 
    print_r($show);

此代码returns

Array ( [0] => WP_Post Object ( [ID] => 79 [post_author] => 1 [post_date] => 2015-03-19 08:58:40 [post_date_gmt] => 2015-03-19 09:58:40 [post_content] =>

但我没能通过 $show[0]['post_title']、$show[0][post_title] 或 $show[0]-> 访问它'post_title'

另外，有没有一种简单的方法可以让这个数组与基本的主题函数一起工作，比如 the_title(); the_content();等等？

你应该重新写成这样：

$feed_sources = array('goose-creek','sleepy-creek','fobr');

foreach ($feed_sources as $feed) {
    $args = array('category_name' => $feed, 'posts_per_page' => 1);

    // we are creating new WP_Query object instead using get_posts() function 
    $shows = new WP_Query($args);

    $shows->the_post();
    // now you can use the_title() and the_content()
    the_title();
}

希望对您有所帮助。
