我会推荐你Options Framework。
如果你还想自己做,这里有一个很长的描述。
https://codex.wordpress.org/Creating_Options_Pages
在这个 Wordpress-Codex 页面上是您需要的一切,您应该尝试一下 - 如果您仍有任何问题,请再次提问。
但作为总结,以下是您必须执行的步骤:
- 创建/注册选项页面,例如
add_options_page() 或add_menu_page() ...
- 注册设置(添加您需要的字段)
- 清理并保存用户输入
另一方面,您可以通过以下方式获得已保存的选项(检查您是否已经保存...):
<?php echo get_option( $option, $default ); ?>
例如
<?php echo get_option( 'blogname' ); ?>
<?php echo get_option( 'myOption' ); ?>
实际上并没有那么难.. 但是使用Options-Framework 会容易得多。
