我写了一个wordpress插件。我的插件有选项。所有选项都在一个组中，“pluginname settings”。所有选项名称都是统一的，看起来像“pluginname settings[\'option-name\']”。一些代码可以说明我的情况：

register_setting( \'pluginname_options\', \'pluginname-settings\', \'pluginname_validate\' );
add_settings_section( \'section-one\', \'Name of Section One\', \'section_one_callback\', \'pluginname_options-sectionname\' );
add_settings_field( \'optionname\', \'First Option\', \'my_text_input\', \'pluginname_options-sectionname\', \'section-button\', array(
    \'name\' => \'pluginname[optionname]\',
    \'value\' => \'42\')
    )

echo "<form action=\\"options.php\\" method=\\"POST\\">";
settings_fields( \'pluginname_options\' );
do_settings_sections( \'pluginname_options-sectionname\' ); 
submit_button(\'Update\', \'primary\',  \'submit-form\', false);
echo "</form>";

据我所知，这是因为所有选项都表示一个设置的数组。

问题：在此设置下，是否可以保存一个节而不清除其他节？在这种情况下，最好的做法是什么？注册单独的设置，使用验证功能填充空格或其他什么？还是只是我做错了？

提前谢谢你。

P、 S：根据评论中的请求，下面是一个最简单的工作示例：
