Here is the current, non-working code:
<?php
$FName="";
$errormsg1="";
if( isset($_POST['FName']){
$FName=$_POST['FName'];
}
if ($FName !=""){
header("Location: write_to_database.php");
}
else{
if ($FName=""){
$errormsg1="Please enter a first name":
}
?>
<html>
<body>
Registration
<?php if ($errormsg1 !=""){ echo $errormsg1; } ?>
<form action="new.htm" method="POST">
First Name: <input type="text" name="FName">
<br />
<input type="submit" name="submit" value="Submit">
</form>
</body>
</html>
