I'm going crazy with some code I've got. I have a signup form, that asks for a username.
I'm trying to build and if else statement that won't insert data into the table if the username is already in the table.

This is my code.
[code]
if($AcceptTerms=="" || $UserPlan=="" ){$errors=1; $error.="<li>You did not enter one or more of the required fields. Please go back and try again.";
} [b]if[/b]($errors==1){ echo $error;}
$link = mysql_connect("localhost","data","passwd");
mysql_select_db("data",$link);
$query2="SELECT Username FROM signup where Username='".$Username."'";
$result2=mysql_query($query2) or die(mysql_error());
$num_rows=mysql_num_rows($result2);
[b]if [/b]($num_rows == 1)
{ echo 'Username in use, hit back button please';
}[b]else[/b] {
$where_form_is="http".($HTTP_SERVER_VARS["HTTPS"]=="on"?"s":"")."://".$SERVER_NAME.strrev(strstr(strrev($PHP_SELF),"/"));
$message="Username: ".$Username."NewPassword1: ".$NewPassword1."NewPassword2:".$NewPassword2."
AcceptTerms: ".$AcceptTerms."UserPlan: ".$UserPlan." ";
$link = mysql_connect("localhost","data","passwd");
mysql_select_db("data",$link);
$query="insert into signup(Username,NewPassword1,NewPassword2,AcceptTerms,UserPlan) values ('".$Username."','".$NewPassword1."','".$NewPassword2."','".$AcceptTerms."','".$UserPlan."')";
mysql_query($query);
?>
<?php
}
?>[/code]

The code pretty much ignores my code to check the db for the username, and goes ahead and inserts the duplicate username and info in the DB.

Any idea's?
if ($AcceptTerms=="" || $UserPlan=="" ){
$errors=1; $error.="<li>You did not enter one or more of the required fields. Please go back and try again.";
}
if($errors==1){
echo "$error";
}
$link = mysql_connect("localhost","data","passwd");
mysql_select_db("data",$link);
$query2="SELECT Username FROM signup where Username='".$Username."'";
$result2=mysql_query($query2) or die(mysql_error());
$num_rows=mysql_num_rows($result2);
if($num_rows == 1){
echo 'Username in use, hit back button please';
}else{
$where_form_is="http".($HTTP_SERVER_VARS["HTTPS"]=="on"?"s":"")."://".$SERVER_NAME.strrev(strstr(strrev($PHP_SELF),"/"));
$message="Username: ".$Username."NewPassword1: ".$NewPassword1."NewPassword2:".$NewPassword2."
AcceptTerms: ".$AcceptTerms."UserPlan: ".$UserPlan." ";
$link = mysql_connect("localhost","data","passwd");
mysql_select_db("data",$link);
$query="insert into signup(Username,NewPassword1,NewPassword2,AcceptTerms,UserPlan) values ('".$Username."','".$NewPassword1."','".$NewPassword2."','".$AcceptTerms."','".$UserPlan."')";
mysql_query($query);
}
?>

Hmm... that still didn't resolve it. I added you as a buddy. msn - msanders@impact-x.com
It still just ignores the username I've inputted and adds it
