You shouldn't register before the form is complete right and not after every
submit.
something
like:
<?
$error='';
if(isset($_POST['yes']))
{
if($_POST['field1'])!=1)$error='field1 is not1 !';
etc...
}
if(empty($error))
{
session_start();
$_SESSION['field1']=$_POST['field1'];
header(Location: next_page);
exit;
}
if(!empty($error)){ echo error.'<br>'}
?>
<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
<input type="text" name="field1" value="<?=isset($_POST['field1']) ?
$_POST['field1'] : ''?>">
etc........
<input type="sumbit" name="yes">
</form>
