漏了一个大括号 
if($row_t !== false)
 {
 $ajax['record']['tp_count'] = $row_t['count'];
}

$.get("/show.php?act=get_toupiao",{
tp_id:tp_id,
all_toupiao:all_toupiao,
hd_id:hd_id,
tp_star_time:tp_star_time,
tp_end_time:tp_end_time,
async:false,
rand: Math.random()
},function(data){
if(data.record.all_tp=="5")
{
alert("今天您已经投票,请明天再投吧!");
                return false;
}
if(data.record.all_tp=="6")
{
alert("今天您已经投票,请明天再投吧!");
                return false;
}
if(data.record.all_tp=="3")
{
alert("投票时间已过,不能投票");
                return false;

if(data.record.all_tp=="4")

                return false;

                return false;
}
if(data.record.all_tp=="2")

                return false;
}
if(data.status.code=="1")
{
//成功
$("#tp_"+tp_id+"").empty();
$("#tp_"+tp_id+"").append(""+data.record.tp_count+"");
alert("投票成功!");
                return false;
}
},"json");

if(data.status.code=="1")
 {
 //成功
$("#tp_"+tp_id+"").empty();
 $("#tp_"+tp_id+"").append(""+data.record.tp_count+"");
 alert("投票成功!");
                 return false;
 }
这里为什么没有提示!

先检查 $sql_t 的内容

toupiao_id             name            huodong_ID            user_id                          time                                count
      31                     张三                      62                    彭斌                   2016-05-09 23:23:27                  21 

内容好像没问题呀,好奇怪呀!

还有一个问题,我的这个IP,如果是在同一个路由器上的机子,IP都是一样的,导到同一个网络不同的机子只能投一次票,怎么办?

我又发现,QQ浏览器打开的,在同一路由器的不同手机获取到的IP就不一样,其它的浏览器在同一路由路网络不同的手机获取到的IP是一样的

Wifi 接入的, ip 不会是一样的!
流量接入的,ip 应该是一样的

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
