This is one of the harder concepts to grasp when programming in a stateless environment; <?php if(!isset($_POST['yourname'])){ $theNameValue = 'Please enter your name'; } else { $theNameValue = $_POST['yourname']; } ?> <form action="<?php echo $PHP_SELF; ?>"method=post> <input name="yourname" type="text" size="20" value="<?php echo $_POST['yourname']; ?>"> <input name="submit" type="submit" value="submit"> </form>
