php会员注册问题

[技术传播]

if ($num1 || $num2) {
die("OVER2");
echo "<script>alert('该用户名已被人使用。');history.go(-1);</script>";
}else {
$db->dealsqlfunc($SQL5);
$db->close();
echo "<script>alert('注册成功');location.href='nocheck.php';</script>" ;
}
第一步：判断当前输入的会员名称是否有重复
第二步：如果正常就可以将数据保存到数据表中去！
我测试的时候发现，数据已经插入到数据库中去了。但是怎么总会 又提示我 “用户名已被人使用”
其中：
$num1 = $db->isExistsRecord($SQL1);
$num2 = $db->isExistsRecord($SQL2);

function isExistsRecord($sql) {
$res = $this->query($sql);
$num_rows = mysql_num_rows($res);
return $num_rows;
}
$SQL1 = "SELECT ZH_ID FROM zh_register WHERE zh_name = '".$value."'";
$SQL2 = "SELECT ZH_ID FROM zh_user WHERE zh_name = '".$value."'"; #会员表验证
$value = strip_tags(substr($_POST['reg_username'],0,32));

问题我觉得就是：当插入数据表之后又马上执行此验证页面！

不知道是什么原因。。。。。。望高手帮我解答下谢谢了

不是吧~~~
你把 echo " <script>alert('该用户名已被人使用。');history.go(-1); </script>";
写在 die（）的后面，echo是永远都不会执行的。
