Here's an example of what I think you're after:
<?
$fields = array(
'name' => 'Name: <input name="name">',
'age' => 'Age: <input name="age">',
'eyes' => 'Eyes: <input type="radio" name="eyes" value="blue"> Blue
<input type="radio" name="eyes" value="brown"> Red'
);
if (isset($_REQUEST['form_posted']))
{
$missing_field = 0;
$good_fields = '';
foreach ($fields as $name => $html)
{
if (!($val = $_REQUEST[$name]))
{
if (!$missing_field)
echo "<form method='post' action='{$_SERVER['PHP_SELF']}'>";
echo "<P>The following field is mandatory:<br>$html</p>";
$missing_field = 1;
}
else
$good_fields .= "<input type='hidden' name='$name' value='$val'>";
}
if ($missing_field)
{
echo $good_fields
. '<input type="submit" name="form_posted"></form>';
exit;
}
else
{
echo "<p>Thank you for your input! Here's what we got:</p><ul>";
foreach (array_keys($fields) as $name)
echo "<li>$name: {$_REQUEST[$name]}</li>";
echo '</ul>';
}
}
else
{
echo "<form method='post' action='{$_SERVER['PHP_SELF']}'>";
foreach ($fields as $f)
echo "$f<br>";
echo '<input type="submit" name="form_posted"></form>';
}
?>
