朋友們 數(shù)據(jù)表有個(gè)字段始終寫(xiě)不進(jìn)去！快來(lái)幫我看看啊....

from_city_id始終寫(xiě)不進(jìn)去，post過(guò)來(lái)的值為8：

代碼

$model = \Common\Plugin\Db::M('XcxMsgRecord');
        $data['from'] = I('post.from');
        $data['from_name'] = I('post.from_name');
        $data['from_avatar'] = I('post.from_avatar');
        $data['from_city_id'] = I('post.from_city_id');
        $data['target'] = I('post.target');
        $data['content'] = I('post.content');
        $data['create_time'] = I('post.create_time');
        $data['teacher_id'] = I('post.teacher_id');
        $data['teacher_name'] = I('post.teacher_name');
        $data['teacher_avatar'] = I('post.teacher_avatar');
        $data['jmsg_id'] = I('post.jmsg_id');
        $data['wx_xcx_form_id'] = I('post.wx_xcx_form_id');
        $id = $model->add($data);
        if($id){
            $this->httpSuccess($id, '消息入庫(kù)成功');
        }else{
            $this->httpError('消息入庫(kù)失敗');
        }
