<?

if( !isset($msg))
{
echo "tes";
}
else
echo "tes1";

?>

<input type="text" name="textfield">
<input type="submit" name="Submit" value="Submit">
</form>
<?

?>

tes2 :

<?
header( "location: tes.php?msg=1" ) ;
?>

when i click on submit button, it will go to tes2.php and tes2.php will redirect back to tes.php and set msg=1
