Timestamp Reminder

[JohnDoe1]

Is there anyway I could create a timestamp in say a form  and have it remind me in 30 days after the form was submitted? A reminder as in a popup or email something like that.This should be my last question. hope I'm not cluttering the forum up.thanks

<input type="hidden" name="timestamp_created" value="<?php print mktime(0, 0, 0, 1, 1);/* 1 january */ ?>">

 

$timestamp_created = (int) $_POST['timestamp_created'];
$a = time() - $timestamp_created;
$thirtydays = 2592000; // 30 days in seconds
$alertinhour = $thirtydays + 3600;
if ($a > 2592000 && $a < $alertinhour) {
    //set some flag the mail have been send, so it doesn't get send twice
    mail(..);
}

It all depends what you're doing with the form.  I would suggest you just save your submitted data along with a timestamp in a MySQL table and then write a script that you set up in your cron to run once a day to send out your reminders.
