使用add_settings_field(); 我可以添加自定义设置：

add_settings_field(\'AUTOPLAY\', \'Auto Play\', \'printAutoPlayCheckbox\', \'my_settings\');


function printAutoPlayCheckbox()
{
   $id = \'AUTOPLAY\';
   $name = \'my_settings\' . "[$id]";
   $options = get_option(\'my_settings\');
   echo \'<input type="checkbox" id="\' . $id . \'" name="\' . $name . \'" \' . checked(1, isset($options[$id]), false) . \'" />\';
}
