PLZ给我编辑EDIT.PHP :(
答案 0 :(得分：0)
如果我在这么晚的时候正确地阅读你的代码 - 而不是这个：
“更新用户设置名称='$ name'，image ='$ pic_name_hid'，image1 ='$ pic_name_hid1'，其中id = $ id”;
试试这个：
“UPDATE users SET name ='”。 $ name。 “'，image ='”。 $ pic_name_hid。 '“，image1 ='”。 $ pic_name_hid1。 '“WHERE id ='”。 $ id。 ““;
我假设你已经检查过你的POST变量确实正确传递（错别字等）
