我有一个我买的 Wordpress 主题，它附带了许多不同的小部件。我有一个带有以下代码的代码，它的作用是显示最近的帖子。我需要对其进行更改，实际上是两个，而不是向我显示最近的 POST，我需要它来向我显示最近的投资组合项目，并且只显示某个类别。
<?php
// =============================== My Recent Posts (News widget) ======================================
class MY_PostWidget extends WP_Widget {
/** constructor */
function MY_PostWidget() {
parent::WP_Widget(false, $name = 'My - Recent Posts');
}
/** @see WP_Widget::widget */
function widget($args, $instance) {
extract( $args );
$title = apply_filters('widget_title', $instance['title']);
$category = apply_filters('widget_category', $instance['category']);
$linktext = apply_filters('widget_linktext', $instance['linktext']);
$linkurl = apply_filters('widget_linkurl', $instance['linkurl']);
$count = apply_filters('widget_count', $instance['count']);
?>
<?php echo $before_widget; ?>
<?php if ( $title )
echo $before_title . $title . $after_title; ?>
<?php $temp = $wp_query;
$wp_query= null;
$wp_query = new WP_Query(); ?>
<ul class="latestpost">

<?php if ($wp_query->have_posts()) : while ($wp_query->have_posts()) : $wp_query->the_post();?>
<li>
<?php if(has_post_thumbnail()) {
echo '<figure class="featured-thumbnail"><a href="'; the_permalink(); echo '">';
echo the_post_thumbnail('small-post-thumbnail');
echo '</a></figure>';
}
?>
<time datetime="<?php the_time('Y-m-d\TH:i'); ?>"><a href="<?php the_permalink(); ?>"><?php the_time('[m-d-Y]'); ?></a></time>

这是它现在在小部件窗格中的样子：
