wordpress后台保存插件、主题的设置

我也是第一次做插件设置页面，之前只是知道使用options表保存数据，但是对于怎么保存却是一知半解，直到我看到wordpress的一篇文章，我才初步了解，wordpress的相关文章在文末。

这是我实现的插件设置页面

相关的代码：


<?php
/* 注册激活插件时调用的函数 */ 
register_activation_hook( __FILE__, 'installtododosomething');
function installtododosomething() {
    /* 在数据库的 wp_options 表中添加一条记录，第二个参数为默认值 */ 
    if(!get_option('qywxtongzhi')){
    add_option("qywxtongzhi", "0", '', 'yes');
    }
    if(!get_option('emailtongzhi')){
    add_option("emailtongzhi", "0", '', 'yes');
    }
    if(!get_option('qywxapi')){
    add_option("qywxapi", "0", '', 'yes');
    }
}
//增加插件管理菜单
//注册设置
add_action( 'admin_init', 'register_xiangmuguanli_settings' );
function register_xiangmuguanli_settings() {
//register our settings
register_setting( 'xiangmuguanli-settings-group', 'qywxtongzhi' );
register_setting( 'xiangmuguanli-settings-group', 'emailtongzhi' );
register_setting( 'xiangmuguanli-settings-group', 'qywxapi' );
}
if(is_admin()) {
    /*  利用 admin_menu 钩子，添加菜单 */
    add_action('admin_menu', 'add_xiangmuguanli_page');
}
function add_xiangmuguanli_page() {
    /* add_options_page( $page_title, $menu_title, $capability, $menu_slug, $function);  */
    /* 页名称，菜单名称，访问级别，菜单别名，点击该菜单时的回调函数（用以显示设置页面） */
    add_menu_page("项目设置", "项目设置", 'administrator', 'xiangmuguanli_page', 'xiangmuguanlipage_html');//管理员显示该菜单，编辑，作者，投稿人等其他人则不显示
}
