Question

这是我的代码的基础。我的想法是，当我点击将表单帖子提交到同一页面并在if语句中运行我的代码时。问题是，当我点击提交时，我收到Wordpress错误，说无法加载tb-export。我做了很多谷歌搜索，找不到解决方案。

再次编辑：我把代码带到了课外并简化了它，我仍然得到错误。以下是简化代码，提交表单后我收到错误无法加载export_display。

add_action('admin_menu', 'tb_admin_menu');
function tb_admin_menu() {
  add_menu_page(
    'Table Builder',
    'Table Builder',
    'read',
    'i15-table-builder',
    '',
    'dashicons-screenoptions',
    21
  );

  add_submenu_page('i15-table-builder', 'Export', 'Export', 'manage_options', 'export_display', 'export_display');
}

    function export_display(){    
        if ($_POST['submit']) {
            $post_args = array(
                    'post_type' => $_POST['post_type'],
                    'post__in' => $_POST['ids']
                );

            $posts = get_posts($post_args);

          $count = 0;
                foreach ( $rtp_posts as $post ) {

                    $write_array[$count] = array(

问题出在我的表格中。以前隐藏输入的名称是post_type。我想这有些东西搞砸了，因为在我摆脱了下划线之后，它起作用了。

echo '<input type="hidden" name="posttype" value="tb_template" />';
