如果出现以下情况，我想在我的帖子旁边显示“新”图像：

  1. 它是在 1 到 45 天前发布的。
  2. 45 天后隐藏/禁用“新”图像。

这是我的轮播代码，它显示了最新的 4 个帖子：

`<!------Begin Carousel Cusomizations-------->
<div class="list_carousel">
<a id="prev2" class="prev" href="#">&lt;</a>
<ul id="foo2">
<?php
global $post;
$args = array( 'numberposts' => -1, 'post_type' => 'guides');
    $posts = get_posts($args);
    foreach( $posts as $post ) : setup_postdata($post); ?>
<li class="productCarousel" onclick="document.location.href='<?php echo the_permalink(); ?>';">
<div class="liContent">
<div class="ribbon"><div class="ribbon-new">New</div></div>
<div class="liPadding">
<?php the_post_thumbnail( array(75,75) ); ?>
<h4><?php the_title(); ?></h4>
<p><?php the_excerpt(); ?></p>
<p class="accessGuides"><a href="<?php echo the_permalink(); ?>">Access Guide</a></p>
</div>
</div>
</li>
<?php endforeach; ?>
</ul>
<a id="next2" class="next" href="#">&gt;</a>
<div class="clearfix"></div>
<div id="pager2" class="pager"></div>
</div>    
</div>
<!----End Carousel Customizations----->`

DIV 部分：<div class="ribbon"><div class="ribbon-new">New</div></div>是我的“新”图像横幅的容器。

非常感谢任何帮助！
