我正在为我的插件创建一个自定义设置页面。我有四个textarea字段，需要替换为wp_editor. 我的问题是我无法将数据存储到数据库中。下面是我的代码。

add_settings_field( 
    \'nga_textarea_field_2\', 
    __( \'SMS templates\', \'wordpress\' ), 
    \'nga_textarea_field_2_render_i\', 
    \'pluginPage\', 
    \'nga_pluginPage_section_4\' 
);

function nga_textarea_field_1_render_i() { 
    $nga_textarea_field_1_invalid = get_option( \'nga_textarea_field_1\' );
    error_log(print_r($nga_textarea_field_1_invalid,1),0);
    wp_editor( $nga_textarea_field_1_invalid, \'nga_textarea_field_1\', array( \'textarea_name\' => \'nga_textarea_field_1\' )); 
    //update_option(\'nga_textarea_field_1_invalid\', $content);
}
