如何保存自定义元类型发布按分类分组的多重检查(使用CMB2)

我正在使用CMB2(https://github.com/CMB2/CMB2) 用于向帖子类型添加新元。

我正在尝试添加一个新的自定义元，其中包含按分类法分组的帖子列表，但我不知道如何保存它们。我想将meta保存为一个数组，如下所示：

array (
  id => array (checked, new_title),
  id2 => array (checked, new_title2)
)

自定义元的源代码：

// Enqueue accordion scripts.
add_action( \'admin_enqueue_scripts\', function($hook){
    if (( \'post.php\' == $hook ) || ( \'post-new.php\' == $hook)) {
        wp_enqueue_script( \'accordion\', \'/wp-admin/js/accordion.js\');
    }
});

// Custom CMB2 field list_category_posts
add_action( \'cmb2_render_post_multicheck_by_category\', \'cmb2_render_post_multicheck_by_category\', 10, 5 );
function cmb2_render_post_multicheck_by_category ( $field, $value, $object_id, $object_type, $field_type  ) {

    // get post_type
    if ($field->args[query_args][post_type])
        if (post_type_exists($field->args[query_args][post_type]))
            $type=$field->args[query_args][post_type];
        else $type=get_post_type($object_id);
    else $type=get_post_type($object_id);

    // get taxonomy    
    if ($field->args[query_args][taxonomy])
        if (taxonomy_exists($field->args[query_args][taxonomy]) && is_object_in_taxonomy($type, $field->args[query_args][taxonomy]))
            $taxonomy=$field->args[query_args][taxonomy];
        else $taxonomy=get_object_taxonomies($type)[0];
    else $taxonomy=get_object_taxonomies($type)[0];

    $posts_data = array();
    $terms = get_terms($taxonomy);
    foreach ($terms as $term) {
        $posts = get_posts(array(
            \'post_type\' => $type,
            \'tax_query\' => array(array(
                \'taxonomy\' => $taxonomy,
                \'terms\' => $term->term_id
            ))
        ));
        foreach ($posts as $post) {
            $posts_data[$term->name][$post->ID] = array ($post->post_title);
        }
    }
    ?>
    <div class="accordion-container">
        <ul class="outer-border">
        <?php foreach ($posts_data as $category => $posts) { ?>
            <li class="control-section accordion-section">
                <h3 class="accordion-section-title hndle" tabindex="0">
                    <?php echo $category; ?>
                </h3>
                <?php foreach ($posts as $post) { ?>
                    <div class="accordion-section-content" style="display: none;">
                        <label class="menu-item-title ">
                            <div><input type="checkbox" class="menu-item-checkbox" value="<?php echo $field_type->_id=$post->ID; ?>">
                            <span><?php echo $post[0]; ?></span>
                                <input type="text">
                            </div>
                        </label>
                    </div>
                <?php } ?>
            </li>
        <?php } ?>
        </ul>
    </div>
    <?php
}

用法：

add_action( \'cmb2_admin_init\', function () {
    $prefix = \'recipes_\';

    $cmb_recipes = new_cmb2_box( array(
        \'id\'            => $prefix . \'metabox\',
        \'title\'         => \'Posts multicheck by category\',
        \'object_types\'  => array( \'recipes\', ), // post type
    ) );

    $cmb_recipes->add_field( array(
        \'name\'       => \'\',
        \'id\'         => $prefix . \'ingredients\',
        \'type\'       => \'post_multicheck_by_category\',
        \'context\' => \'side\',
        \'query_args\' => array (
            \'post_type\' => \'ingredients\',
            \'taxonomy\' => \'ingredients-category\',
        ),
    ) );

} );

<input type="text" name="name[]" /> <input type="text" name="email[]" /> <input type="text" name="name[]" /> <input type="text" name="email[]" /> <input type="text" name="name[]" /> <input type="text" name="email[]" />

CPT GROUP BY DATE Metabox值

我正在使用自定义帖子类型构建一个事件插件。我运行了一个循环，它将使用一个短代码显示页面上的所有事件。我的问题是如何设置它，以便它按元数据库中设置的月份对事件进行分组_eDate 并将该组放在一个标题下。例如，7月的所有事件将显示在7月h1标记下。以下是我当前使用的循环：function events_list_shortcode() { // Query Post Type $args = array( \'post_type\' =>
