我正在创建一个 WordPress 模板。我在front-page.php. 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，他可以在作品集中的成就中选择他想要在主页中显示的成就。我指定这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">

        }

        if (array_key_exists('capacity_meta_box_front_page_portfolio_show', $_POST) and $_POST['capacity_meta_box_front_page_portfolio_show']=='yes' ) {
            update_post_meta(
            $post_id,
            '_capacity_meta_box_front_page_portfolio_categories',
            $_POST['capacity_meta_box_front_page_portfolio_categories']
            );
        }
    }

add_action('save_post', 'capacity_save_page_data');

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; ?>

奇怪的事情发生了：页面上的所有元框都被复制了。在这里看图.

当我用帖子类型替换自定义帖子类型capacity_portfolio时page- 它有效。但是，当我用 post type 替换它时post，它不起作用。我说，当我删除这段代码时，metabox 可以正常工作。

<?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();
?>

问题已经解决了...
