生成字段控件-编辑器字段的问题

生成字段控件-编辑器字段，

因为要加一个分组，比如字段名desc，需要加入setting组中，

$data['setting']['desc']

在模板中如下这样写不对

<?php echo dr_fieldform('{"name":"简介","fieldname":"setting.desc","ismain":"1","fieldtype":"Editor","setting":{"option":{"show_bottom_boot":"0","imgtitle":"0","imgalt":"0","watermark":"0","imagecut_ext":"","image_ext":"jpg,gif,png,webp,jpeg","image_size":"10","attach_size":"200","attach_ext":"zip,rar,txt,doc","video_ext":"mp4","video_size":"500","attachment":"0","value":"","width":"","height":"","css":""},"validate":{"required":"0","pattern":"","errortips":"","check":"","filter":"","formattr":"","tips":""}},"ismember":"1"}', $data['setting']['desc'], 1, 1);?>

['setting']['desc']、setting.desc都不对，报错

这里应该怎样写才对呢？
