PHP and html

I have one problem. I am having two pages. In first page if I leave some mantitoy fields empty and if I click submit. The same first page must be displayed with changing the color(to red) of the names of the manditory fields that are not filled but all other data in other fields must be there. I don't know how to do it. Since I am new to php and using PHP3. Please help me.

Try the form.php3 file

<?
function TestField($f)
{
if ($f == "")
print "<font color='#FF0000'>";
}

$field_list = array("Name", "Firstname");

if ($REQUEST_METHOD == "POST")
{ for($i=0; $i<count($field_list);$i++)
{ if ($$field_list[$i] == "")
$err=true;
}
if ($err<>true)
header("Location: confirm.php3");
}
?>

<form action="form.php3" method="post">
<?TestField($Name)?>Name</font>
<input type="text" value="<?print $Name?>" name="Name"><br>
<?TestField($Firstname)?>Firstname</font>
<input type="text" value="<?print $Firstname?>" name="Firstname"><br>
<input type="submit" value="submit" name="submit">
</form>

Sure, when you refresh, you post again your data.
What do you need to do ?
