<form action="inseting.php" method="post">
<? require("password.php");
mysql_select_db("database");
$query="select first, second from table1";
$result=mysql_query($query);
$a=0;
<input type="select" name="xxxxx">
while ($row=mysql_fetch_objects($result))
{ $first[]=($row->first);
$second[]=($row->second);
print("<option value='$first[$a]'>$second[$a]</option>");
$a++;
}
</form>
then in the page of inserting.php
<?require("Password.php");
mysql_select_db("database");
$query="insert into table2 values ("$xxxxx");
------okay------ in the meantime of submitting page1 and exec
inserting.php. Anyone updated the table1, I will get the different values
in table2. Is that right!! So I just don't want this to be happened.
Thank You
mark Lo
