this worked for me.
<?
$entries = 20;
for ($i=1; $i<=$entries; $i++) {
if(isset($_POST["resolutions$i"]) && $_POST["resolutions$i"] !==
''){
echo "Hello $i<br />";
}
}
?>
<html>
<body>
<form method="POST">
<input type="hidden" name="resolutions1" value="etefgtE" />
<input type="hidden" name="resolutions3" value="etefgtE" />
<input type="hidden" name="resolutions5" value="etefgtE" />
<input type="hidden" name="resolutions6" value="etefgtE" />
<input type="hidden" name="resolutions15" value="etefgtE" />
<input type="hidden" name="resolutions12" value="" />
<input type="submit" name="submit" />
</form>
</body>
</html>
