在元框中循环自定义帖子类型
我正在创建一个WordPress模板。我在front-page.php上添加了一个元框。我希望用户可以选择在主页上显示或不显示他的成就。如果他想展示他的成就，他可以在主页中选择他想要在投资组合中显示的成就中显示的成就。我指定capacity_portfolio是自定义帖子类型。
<?php
function capacity_page_add_custom_box() {
$screens = ['page', 'capacity_service', 'capacity_portfolio'];
foreach ($screens as $screen) {
add_meta_box(
'capacity_page_custom_box', // Unique ID
'Customize this page', // Box title
'capacity_page_box_html', // Content callback, must be of type callable
$screen // Post type
);
}
}
add_action('add_meta_boxes', 'capacity_page_add_custom_box');
function capacity_page_box_html($post) {
require get_parent_theme_file_path( '/template-parts/page-excluded-blog/page-excluded-blog.php' );
?>
<div class="capacity-metabox-container">
<table class="form-table capacity-metabox-table">

<?php $post_id = $_GET['post'] ? $_GET['post'] : $_POST['post_ID'] ;?>

有问题的部分：
<?php $args = array( 'post_type' => 'capacity_portfolio'); ?>
<?php $loop = new WP_Query( $args ); ?>
<?php if ($loop->have_posts()) : while ( $loop->have_posts() ) : $loop->the_post(); ?>
<?php the_title(); ?><br>
<?php endwhile; ?>
<?php endif; ?>
发生了一件奇怪的事情：页面上的所有元框都是重复的。
当我使用帖子类型capacity_portfolio替换自定义帖子类型page时 - 它可以正常工作。但是，当我用帖子类型post替换它时，它不起作用。
我说，当我删除这段代码时，metabox正常工作。

<?php
$args = array('post_type' => 'capacity_portfolio', 'orderby' => 'modified');
$pages = get_posts( $args );
foreach ( $pages as $page ) : setup_postdata( $page );
echo $page->post_title;
endforeach;
wp_reset_postdata();
?>
