最简单的方法是设置窗体的action=\'\' 并使用global $plugin_page; 如中所述Notes 第节add_submenu_page().

例如：

add_action (\'network_admin_menu\', \'add_network_menus\') ;

function
add_network_menus ()
{
    add_menu_page (\'My Page Title\', \'My Menu Title\',
        \'manage_network\', \'my_menu_slug\', \'my_network_admin_page\') ;
    add_submenu_page (\'my_menu_slug\', \'Some Subpage Title\',
        \'My Submeny Title\', \'manage_network\', \'my_submenu_slug\',
        \'network_admin_subpage\') ;

    return ;
}

function
network_admin_page ()
{
    global $title, $plugin_page ;

    echo <<<EOF
<div class=\'wrap\'>
    <div id=\'icon-tools\' class=\'icon32\'></div>
    <h2>$title</h2>

    <p>more content here</p>
</div>
EOF;

    return ;
}

function
network_admin_subpage ()
{
    global $title, $plugin_page ;

    echo <<<EOF
<div class=\'wrap\'>
    <div id=\'icon-tools\' class=\'icon32\'></div>
    <h2>$title</h2>

    <p>more content here</p>
    <form action=\'\' method=\'GET\'>
        <input type=\'hidden\' name=\'page\' value=\'$plugin_page\' />
        <input type=\'submit\' value=\'Submit\'>
    </form>
</div>
EOF;

    return ;
}
