我正在努力让我的设置页面保存我的选项。我已经把它正确显示出来了，它会启动消毒功能

    register_setting(
        \'my_options\', // Option group
        \'my_settings\', // Option name
        array($this, \'sanitize\') // Sanitize
    );

在sanitize函数上运行调试器时，$input为null：

public function sanitize($input)
{
    $new_input = array();

    $new_input = $input;
    //Sanitize the input actually

    return $new_input;
}

表单本身的名称如下：

<form id="my-admin-form" method="post" action="options.php">
    <!-- Submission Notices -->
    <div class="status-box notice notice-info" style="display: none;"></div>
    <?php
    settings_fields(\'my_options\');
    do_settings_sections(\'my_section\');
    submit_button();
    ?>
</form>

<input id="my_option[key]" type="text" name="my_option[key]" value="<?php !empty(my_option[key]) ? my_option[key] : NULL; ?>">
