您好，我目前正在遵循一个关于如何向我创建的子菜单页面添加输入的指南。Here 是显示内容的图片。当我查看子菜单页时。

没有错误，只是没有显示文本字段。函数函数mytheme_general_name() 第二天没有接到电话add_submenu_page, 但我看不出有什么问题。

我复制了这是我当前使用的两个php文件

文件名：function-admin.php

/*

@package Jeron

    ========================
        ADMIN PAGE
    ========================
*/

function mytheme_add_theme_options() {
    // Generate Theme Options Page
    add_menu_page(\'My Themes Theme Options\', \'Theme Options\', \'manage_options\', \'theme2_options\', \'mytheme_create_page\', get_template_directory_uri().\'/img/themeoptionsicon.png\', 110);

    // Generate Theme Options Sub Pages
    add_submenu_page(\'theme2_options\', \'Theme Options\', \'General\', \'manage_options\', \'theme2_options\', \'mytheme_create_page\');
    add_submenu_page(\'theme2_options\', \'Typography\', \'Typography\', \'manage_options\', \'theme_options_typography\', \'mytheme_create_typography_page\');

}

}
