所以，我目前正在建立一个基于模板事件v2主题的网站。我已经做了一些工作正常的定制，但这个有点超出我的范围。
问题如下。
我需要构建一个小部件，它只输出标记为要素的事件（自定义帖子）。现在我有一些不同的方式来显示事件，但它们几乎只是按类别或按日期排序。
示例网站：http://www.blaest.no/jonnysnorkel
以下是我正在处理的小部件的小部件的当前代码：
class blaestfeatured extends WP_Widget {
function blaestfeatured() {
//Constructor
$widget_ops = array('classname' => 'widget category List View', 'description' => 'Custom Featured event widget by Christoffer Sandstrøm' );
$this->WP_Widget('blaestfeatured', 'blaestfeatured', $widget_ops);
}
function widget($args, $instance) {
// prints the widget
extract($args, EXTR_SKIP);
echo $before_widget;
$widget_id= $args['widget_id'];
$title = empty($instance['title']) ? '' : apply_filters('widget_title', $instance['title']);
$category = empty($instance['category']) ? '' : apply_filters('widget_category', $instance['category']);
$post_number = empty($instance['post_number']) ? '5' : apply_filters('widget_post_number', $instance['post_number']);
$post_link = empty($instance['post_link']) ? '' : apply_filters('widget_post_link', $instance['post_link']);
$more_link = empty($instance['more_link']) ? '' : apply_filters('widget_more_link', $instance['more_link']);
$character_cout = empty($instance['character_cout']) ? '15' : apply_filters('widget_character_cout', $instance['character_cout']);
$sorting = empty($instance['event_sorting']) ? 'Latest Published' : apply_filters('widget_event_sorting', $instance['event_sorting']);

答案 0 :(得分：1)
以下是您的查询：
$args = array(
'post_type' => 'my_custom_post_type',
'posts_per_page' => 10,
'meta_query' => array(
array(
'key' => 'featured_h',
'value' => 'h',
)
)
);
$query = new WP_Query($args);
while( $query->have_posts() ) : $query->the_post(); ?>
<li id="post-<?php the_ID(); ?>" <?php get_post_class(); ?> ><?php } ?>
<h3 class="<?php echo $postclasscategory; ?>" > <?php echo get_formated_date(get_post_meta($post->ID,'st_date',true));?> </h3>
<div class="eventcontainer">
<?php if(get_post_meta($post->ID,'featured_h',true) == 'h' ) { ?><div class="featured_img_s"></div><?php }?>
<?php if ( $thumb != '' ) { ?>
<a class="headliner-img" href="<?php the_permalink(); ?>">
<img src="<?php echo $thumb; ?>" width="290" alt="<?php the_title(); ?>" title="<?php the_title(); ?>" /></a>
<?php
