我被难住了。我一直在疯狂地研究这个，但我似乎不明白为什么register_setting() 对我没用。我是WP插件开发的新手（很明显），所以我可能错过了一些愚蠢的东西。看看吧。

我正在构造函数中运行此函数：

add_action( \'admin_init\', array( $this, \'register_settings_and_fields\') );

然后，我有以下代码可以执行我需要的内容：

/**
 * Register the settings and fields for the plugin settings page.
 *
 * @since    1.0.0
 */
public function register_settings_and_fields() {

    register_setting(\'my_plugin_settings\', \'my_plugin_settings\');

    add_settings_section(
        \'my_plugin_main_section\',                          // ID used to identify this section and with which to register options
        \'Main Settings\',                                   // Title to be displayed on the administration page
        array($this, \'my_plugin_main_settings_callback\'),  // Callback used to render the description of the section
        $this->plugin_slug                                 // Page on which to add this section of options
    );

    // Begin defining the fields
    add_settings_field(\'my_plugin_data_1\', \'Data 1\', array( $this, \'my_plugin_data_1_setting\' ), $this->plugin_slug, \'my_plugin_main_section\');
}

// ... and of course other lines of code.

当然，我有更多的代码来执行诸如定义回调函数等操作。一切似乎都执行得很好，设置部分/字段显示正确。但当我去/wp-admin/options.php, 尚未创建my\\u plugin\\u设置。

我被难住了。有什么想法吗？如果您想查看更多代码，请告诉我。

settings_fields( \'my_plugin_settings\' );
do_settings_sections( \'my_plugin_settings\' );

submit_button();

/* If the options do not exist then create them*/
if ( false == get_option( \'my_plugin_settings\' ) ) {
    add_option( \'my_plugin_settings\' );
}

register_setting($this->plugin_slug, \'my_plugin_settings\');

add_settings_section(
        \'my_plugin_main_section\',                          // ID used to identify this section and with which to register options
        \'Main Settings\',                                   // Title to be displayed on the administration page
        array($this, \'my_plugin_main_settings_callback\'),  // Callback used to render the description of the section
        $this->plugin_slug                                 // Page on which to add this section of options
    );
