无法在 WordPress 中使用自定义小部件在页面上显示 5 个帖子

Cannot display 5 posts at the page using custom widget in WordPress

我正在尝试在小部件中显示 5 个帖子。我所做的只是:

$post_arguments = array(
     'posts_per_page' => 5,
     'post_status'    => 'publish',
     'post_type'      => 'industry_news'
);
$posts_array = get_posts( $post_arguments );

到目前为止一切顺利,在我的 html 中我有以下 foreach:

foreach ($posts_array as $single_post) {
            ?>
            <ul class="tabs-content">
                <li class="tab-active">
                    <div class="article"><a href="#"><img width="260" height="140" class="wp-post-image" alt=""></a>
                        <h3 class="title">
                            <a href="http://example.com/example"
                               title=""><?php $single_post->post_title ?></a>
                        </h3>
                        <p><?php $single_post->post_content ?></p>
                    </div>
                </li>
            </ul>
        </div>
        <?php
        }

问题是 post_contentpost_title 没有显示在页面中。为什么?

请使用'echo'

foreach ($posts_array as $single_post) {
            ?>
            <ul class="tabs-content">
                <li class="tab-active">
                    <div class="article"><a href="#"><img width="260" height="140" class="wp-post-image" alt=""></a>
                        <h3 class="title">
                            <a href="http://staging.smartmeetings.com/destinations/98313/south-carolina-food-guide"
                               title=""><?php echo $single_post->post_title ?></a>
                        </h3>
                        <p><?php echo $single_post->post_content ?></p>
                    </div>
                </li>
            </ul>
        </div>
        <?php
        }
