为了处理插件选项，我假设您创建了某种选项页面？

下面是一个在选项页面中创建复选框设置的示例，包括验证和其他所有内容。只需创建一个新的“myplugin admin.php”文件并插入代码。只有一个设置：从wp区域移除垃圾。然后将管理文件包含在主插件php文件中（例如myplugin.php）->包含“myplugin admin.php”；

<?php

// SETUP THE MENU
function myplugin_setup_menu(){
        add_options_page( \'Settings\', \'MyPlugin\', \'manage_options\', __FILE__, \'myplugin_build_options_page\' );
}

// BUILD OPTIONS PAGE
function myplugin_build_options_page(){ ?>

<div id="myplugin" class="wrap">

    <div id="icon-options-general" class="icon32"></div>

    <h2 class="options-title">MyPlugin <?php _e("Settings"); ?></h2>

    <form method="post" action="options.php" class="options-form">
