Please use the

tags.

Anyhow, you forgot to add in your query what fields should be occupied.

For example:

mysql_query("INSERT INTO users (id, username, password, gender, birthyear) VALUES(`id`,'".$username."','".$password."','".$gender."'.".$byear.")");

Please note, I am not sure if I used the right field-names, you have to check your database for that.

mysql_query("INSERT INTO users VALUES(`id`,'".$username."','".$password."','".$gender."'.".$byear.")")

I am assuming the id you are trying to insert is an autonumber fiedld. If that is true, then instead of `id`, use NULL:

mysql_query("INSERT INTO users VALUES(NULL,'".$username."','".$password."','".$gender."'.".$byear.")")

(the database will autoincrement instead of actually inserting null).

if($curnum == 0)
{
mysql_query("INSERT INTO users VALUES(`id`,'".$username."','".$password."','".$gender."'.".$byear.")") or die(mysql_error());

}

put $id instead of id in query. but there is no need to put $id. it is not a manuall entry value. and next change ',' instead of '.'

'".$gender."'.".$byear."

here. just leave it use like this.

if($curnum == 0)
{
mysql_query("INSERT INTO users VALUES('".$username."','".$password."','".$gender."','".$byear."')") or die(mysql_error());

}

i think this code help you, here '' use for id which auto increments

$query = "insert into user values('','$username','$password','$gender','$byear')";
$result = mysql_query($query) or die('Error!');
if($result){
echo " NAME :- $username";
}

instead of these:

$password= $_POST['password'];
$gender= $_POST['gender'];
$byear= $_POST['birth_year'];

you can dynamically create those variables using a foreach. The name of the the variable would
match the relevant key in $_POST. Thus, since your $_POST has birth_year, then your variable will be $birth_year instead
of $byear.

WOW I think everyone is actually pretty onto it with this one.
As a hint use mysql_real_escape_string, don't let people hack your site.
also use sessions to make sure they are coming from your site etc...
read my tutorial on this on my page http://www.effectivewebdesign.co.nz/tutorial.php
save yourself a headache later on :)
