Question

I have set up a schedule email script using listmailpro. I need to schedule a email to be sent for each Monday of the month for the next couple of years. The example below shows what I am trying to achieve. How could I write a quick PHP script that will insert the schedules for me, changing the date for each insert?

INSERT INTO `lm_schedule` (`id`, `type`, `date`, `subject`, `message`, `htmessage`, `fattach`, `list`) VALUES
('', 'm', '2011-08-15', 'Test weekly email (!date2)', 'email text', 'email body', '', '1'),
('', 'm', '2011-08-22', 'Test weekly email (!date2)', 'email text', 'email body', '', '1'),
('', 'm', '2011-08-29', 'Test weekly email (!date2)', 'email text', 'email body', '', '1'),
('', 'm', '2011-09-05', 'Test weekly email (!date2)', 'email text', 'email body', '', '1');

Answer 1

Not tested but should give a rough idea:

$init = strtotime('2011-08-15');
$stop = strtotime('2013-08-15');
$step = 604800;

switch (date('w', $init)) {
    case 0:
        $correction = 1;
        break;
    case 1:
        $correction = 0;
        break;
    case 2:
        $correction = 6;
        break;
    case 3:
        $correction = 5;
        break;
    case 4:
        $correction = 4;
        break;
    case 5:
        $correction = 3;
        break;
    case 6:
        $correction = 2;
        break;
}
$init += $correction * $step;

$qry = 'INSERT INTO `lm_schedule` (`id`, `type`, `date`, `subject`, `message`, `htmessage`, `fattach`, `list`) VALUES (';
$dates = array();

for ($timestamp = $init; $timestamp < $stop; $timestamp += $step) {
    $dates[] = ' ... ' . date('Y-m-d', $timestamp) . ' ... ';
}

$qry .= implode('),(', $dates) . ');';
