我创建了自定义帖子类型，然后我执行了以下操作： 在主页中我有一个正常的循环，我显示该帖子类型的内容，如自定义字段，缩略图等。
然后，通过functions.php我创建了一个小部件，允许我根据类别显示2个自定义帖子类型。 一切正常，但当我查看页面时，自定义字段不显示。
我使用的代码在我的第一个主页循环中起作用：
<?php echo get_post_meta($post->ID, 'game_offer', true); ?>
由于某些原因，我在窗口小部件的函数中的循环中不起作用。
此处是您可以看到自定义字段存在于后端的图像。
在需要的情况下，函数中的代码如下所示：
class My_Widget extends WP_Widget {
public function __construct() {
$widget_ops = array(
'classname' => 'my_widget',
'description' => 'Custom Post Type widget',
);
parent::__construct( 'my_widget', 'Cutom Post Type Widget', $widget_ops );
}
public function widget( $args, $instance ) {
echo '<section id="custom_post_type_widget">';
?>
<div class="top_bar">
<h3 class="border-radius">Top Casino Offers</h3>
</div>
<?php
$mypost = array(
'post_type' => 'game_reviews',
'posts_per_page' => 2,
'type' => 'top-casino-offers',
);
$loop = new WP_Query( $mypost );
while ( $loop->have_posts() ) : $loop->the_post();?>
<div class="custom_post_widget_container flex outer">
<div class="left">
<?php
$url = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
if ( has_post_thumbnail() ) {
echo '<div class="game_imag">';
echo the_post_thumbnail();
echo '</div>';
}
?>
</div>
<div class="right">
<div>
<div class="flex">
<div>
<p>
<span class="title"><?php the_title(); ?></span> | <span class="rating">
<?php
$nb_stars = intval( get_post_meta( get_the_ID(), 'game_rating', true ) );
for ( $star_counter = 1; $star_counter <= 5; $star_counter++ ) {
if ( $star_counter <= $nb_stars ) {
echo '<img src="'.get_template_directory_uri().'/images/icon.png"/>';
} else {
echo '<img src="'.get_template_directory_uri().'/images/grey.png"/>';
}
}
?>
</span>
</p>
<ul class="custom-field-list">
<li><?php echo get_post_meta($post->ID, 'game_offer', true); ?></li>
</ul>
<?php echo get_post_meta($post->ID, 'game_offer', true); ?>
</div>
<div class="right">
<ul class="play-reviews flex">
<li><a href="#" class="play_now">Play Now</a></li>
<li><a href="#" class="reviews">Reviews</a></li>
</ul>
</div>
</div>
<p><?php echo get_the_excerpt(); ?><a class="read-more" href="<?php the_permalink(); ?>">Read More</a></p>
</div>
</div>
</div>
<?php endwhile; ?>
<?php wp_reset_query();
echo '</section>';
}
}
add_action( 'widgets_init', function(){
register_widget( 'My_Widget' );
});
如何显示自定义字段？

使用query_posts而不是WP_Query
<?php
class My_Widget extends WP_Widget {
public function __construct() {
$widget_ops = array(
'classname' => 'my_widget',
'description' => 'Custom Post Type widget',
);
parent::__construct( 'my_widget', 'Cutom Post Type Widget', $widget_ops );
}
public function widget( $args, $instance ) {
echo '<section id="custom_post_type_widget">';
?>
<div class="top_bar">
<h3 class="border-radius">Top Casino Offers</h3>
</div>
<?php
global $post;
$game_reviews_args=array(
'post_type' => 'game_reviews',
'post_status' => 'publish',
'showposts' => 2,
'tax_query' => array(
array(
'taxonomy' => 'type', //taxonomy name
'terms' => 'top-casino-offers', //category name slug
'field' => 'slug'
)
),
'orderby' => 'date',
'order' => 'DESC'
);
query_posts($game_reviews_args);
if (have_posts()) :
while (have_posts()) : the_post();
?>
<div class="custom_post_widget_container flex outer">
<div class="left">
<?php
$url = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
if ( has_post_thumbnail() ) {
echo '<div class="game_imag">';
echo the_post_thumbnail();
echo '</div>';
}
?>
</div>
<div class="right">
<div>
<div class="flex">
<div>
<p>
<span class="title"><?php the_title(); ?></span> | <span class="rating">
<?php
$nb_stars = intval( get_post_meta( $post->ID, 'game_rating', true ) );
for ( $star_counter = 1; $star_counter <= 5; $star_counter++ ) {
if ( $star_counter <= $nb_stars ) {
echo '<img src="'.get_template_directory_uri().'/images/icon.png"/>';
} else {
echo '<img src="'.get_template_directory_uri().'/images/grey.png"/>';
}
}
?>
</span>
</p>
<ul class="custom-field-list">
<li><?php echo get_post_meta($post->ID, 'game_offer', true); ?></li>
</ul>
<?php echo get_post_meta($post->ID, 'game_offer', true); ?>

<div class="right">

<p><?php echo get_the_excerpt(); ?><a class="read-more" href="<?php the_permalink(); ?>">Read More</a></p>
</div>
</div>
</div>
<?php
endwhile;
endif;
wp_reset_query();
echo '</section>';
}
}
add_action( 'widgets_init', function(){
register_widget( 'My_Widget' );
});
?>

所以我认为我需要的只是WP_Query实例之前的全局$ post变量：
global $post;
