最近做一destoon项目，因注册字段太多，分了几个步骤。分几个页面来修改公司信息。发现有时候修改时以前保存的字段莫名丢失.。
经查是 因为member.class.php add 和 edit时,set_member函数 初始化了一些字段，当提交的表单不含这些字段时，这些字段会初始化成空字符。所以保存后会丢失
解决方法
1、不使用$do->edit($post) 函数 自己重写保存程序
2、在表单里增加隐藏字段 把set_member里初始化过的字段一块提交
3、在调用$do->edit($post) 之前 赋值一编 例如 post[“mail”]=$user[‘mail’]
set_member里初始化的字段
$member[’email’]
$member[‘mail’]
$member[‘msn’]
$member[‘qq’]
$member[‘postcode’]
$member[‘ali’]
$member[‘skype’]
$member[‘address’]
$member[‘mode’]
$member[‘keyword’] = $member[‘company’]; //把公司名做关键词
$member[‘homepage’]
$member[‘capital’]
$member[‘sound’] //默认成了０
如果是修改还初始化了
$member[‘banktype’]
$member[‘keyword’]
以下是对应解决代码 放到$do->edit($post)之前 下边是所有需要的字段，别忘了去除当前页面需要修改的，否则。。。
[code]
//解决代码开始
//判断了必填类型的
$post[‘truename’] = $user[‘truename’];
$post[‘groupid’] = $user[‘groupid’]; //会员组
$post[‘passport’] = $user[‘passport’]; //通行证，昵称?????
//set_member初始化的
$post[’email’]=$user[’email’];
$post[‘mail’] =$user[‘mail’];
$post[‘msn’]=$user[‘msn’];
$post[‘qq’]=$user[‘qq’];
$post[‘postcode’]=$user[‘postcode’];
$post[‘ali’]=$user[‘ali’];
$post[‘skype’]=$user[‘skype’];
$post[‘address’] =$user[‘address’];
//$post[‘mode’]=$user[‘mode’]; //mode 应该是string[] 与sell一样
if($user[‘mode’]){
$post[‘mode’]=explode(“,”,$user[‘mode’]);
}
$post[‘keyword’] = $user[‘keyword’];
$post[‘homepage’]=$user[‘homepage’];
$post[‘capital’]=$user[‘capital’];
$post[‘sound’]=$user[‘sound’];
$post[‘banktype’]=$user[‘banktype’];
$post[‘keyword’]=$user[‘keyword’];
$post[‘content’]=$user[‘content’]; //内容字段比较特殊，ｄｔ里内容字段时另表存放的 在前边需要给$user[‘content’]赋值
//解决代码结束[/code]
前边处理$user[‘content’] 的代码
[code]$content_table = content_table(4, $_userid, is_file(DT_CACHE.’/4.part’), $DT_PRE.’company_data’); //返回内容表 siyi_company_data
$t = $db->get_one(“SELECT * FROM {$content_table} WHERE userid=$_userid”);
if($t) {
$user[‘content’] = $content = $t[‘content’]; //公司简介
} else {
$user[‘content’] = $content = ”;
$db->query(“REPLACE INTO {$content_table} (userid,content) VALUES (‘$_userid’,”)”);
