我的自定义帖子类型有一个元框，它在元框中列出了另一个自定义帖子类型。每次我尝试发布具有该自定义帖子类型的帖子时，它都会导致错误。它总是出现在一个页面上，上面写着“你确定要这样做吗？请再试一次”。它在我的localhost中没有任何问题，但在我的web主机上运行时不起作用。

以下是代码：

add_action( \'add_meta_boxes\', \'ind_pricing_tables_boxes\' );

function ind_pricing_tables_boxes() {
    $screens = array( \'indtable\' );
    foreach ($screens as $screen) {
    add_meta_box(\'indtable_boxid\', __( \'Pricing Table\', \'pricing_table\' ), \'ind_pricing_tables_boxes_form\', $screen );
    }
}

function ind_pricing_tables_boxes_form() {
    global $post;
        wp_nonce_field( \'ind_pricing_table_box_nonce\' );
    $ind_table_packs = get_post_meta($post->ID, "_ind_meta_table_keypacks", true);
    $ind_table_packs = ($ind_table_packs == \'\') ? array() : json_decode($ind_table_packs);

    $query = new WP_Query(array(
                \'post_type\' => \'indpackage\',
                \'post_status\' => \'publish\',
                \'posts_per_page\' => -1,
                \'orderby\' => \'post_date\',
                \'order\' => \'ASC\'
                    )
    );

    $ind_form_box  = \'<table class="form-table" border="1">\';
    $ind_form_box  .= "<tr><th style=\'\'>
                    <b>Select Package</b>
              </th>
              <td>
                    <b>Package Names</b>
              </td></tr>";

    while ($query->have_posts()) : $query->the_post();
        $checked_whichs = (in_array($query->post->ID, $ind_table_packs)) ? "checked" : "";
        $ind_form_box  .= "<tr><th style=\'\'>
                    <input type=\'checkbox\' name=\'pricing_ind_table_packages[]\' $checked_whichs value=\'" . $query->post->ID . "\' />
              </th><td>" . $query->post->post_title . " </td></tr>";

    endwhile;

    $ind_form_box  .= \'</table>\';

    echo $ind_form_box ;
}

Save metabox function

function ind_save_pricing_boxtables($post_id) {

    if (!wp_verify_nonce($_POST[\'ind_pricing_table_box_nonce\'], basename(__FILE__))) {
        return $post_id;
    }

    if (defined(\'DOING_AUTOSAVE\') && DOING_AUTOSAVE) {
        return $post_id;
    }

    if (\'indtable\' == $_POST[\'post_type\'] && current_user_can(\'edit_post\', $post_id)) {

        $pricing_ind_table_packages = (isset($_POST[\'pricing_ind_table_packages\']) ? $_POST[\'pricing_ind_table_packages\'] : array());
        $pricing_ind_table_packages = json_encode($pricing_ind_table_packages);

        update_post_meta($post_id, "_ind_meta_table_keypacks", $pricing_ind_table_packages);
    } else {
        return $post_id;
    }
}
