问当我从表检索值到另一个表时，它插入为空。

EN

<?
include('conf.php');

// Passkey that got from link
$passkey=$_GET['passkey'];

$tbl_name1="users";

// Retrieve data from table where row that match this passkey
$sql1="SELECT * FROM $tbl_name1 WHERE confirm_code ='$passkey'";
$result1=mysql_query($sql1) or die ("error1") ;

// If successfully queried
if($result1){

// Count how many row has this passkey
$count=mysql_num_rows($result1);

// if found this passkey in our database, retrieve data from table "users"
if($count==1){

$rows=mysql_fetch_array($result1);
$username=$_POST['uname'];
$fname=$_POST['fname'];
$password=$_POST['password'];
$email=$_POST['email'];

$tbl_name2="registered_members";

// Insert data that retrieves from "users" into table "registered_members"
$sql2=("INSERT INTO $tbl_name2 (uname,fname,password,email,age,gender)VALUES('$username','$fname','$password','$email','$age','$gender')");
$result2=mysql_query($sql2) or die ("error insert");
}

// if not found passkey, display message "Wrong Confirmation code"
else {

}

// if successfully moved data from table"users" to table "registered_members" displays message "Your account has been activated" and don't forget to delete confirmation code from table "users"
if($result2){
