coding syntax help

[grudz]

Hi,

I am building a page where a user enters a date (through 3 drop down boxes : month, day, year) into one field (sent), then another field (due) is automatically generated (sent + 30 days)

Now this is what i have so far



$d = $_POST['d'];
$m = $_POST['m'];
$y = $_POST['y'];
$sent = "".$m." ".$d.", ".$y."";
$due = date($sent, strtotime("+30 days"));



but the due date doesnt generate in my database......

Can anybody help me out?

Thank you

Umm... date() doesn't add dates... you should try
strtotime("$y/$m/$d") + strtotime('+30 days')

If i try that piece of code....and put April 1, 2005 as my sent date, it gives me "1117661194" as my due date?

No wait... you don't want to add the two dates. (why did I think you want to add the date?)
You want the due date output correctly.

<?php
print date('Y M d h:i:s', strtotime('+30 days'));
?>

You can tweak the format. You can read about it on the date() (http://www.php.net/date) functuion page.

i should make myself a bit more clear...i want to add 30 days to whatever date I use in the dropdown date



$d = $_POST['d'];
$m = $_POST['m'];
$y = $_POST['y'];

$sent = "".$m." ".$d.", ".$y."";
$due = $sent + 30 days;

Oh well then this:

print date('Y M d h:i:s', strtotime("$y/$m/$d") + 60 * 60 * 24 * 30);

[grudz]

it still gives me June 1, 2005 (30 days after today's date) even if i select April 1, 2005 as the sent date

You know it shouldn't do that... Is the month numeric or named (like January)?
If it's not numeric you could try this:

print date('Y M d h:i:s', strtotime("$d $m $y") + 60 * 60 * 24 * 30);

You could read this fascinating manual about date input formats (http://www.gnu.org/software/tar/manual/html_chapter/tar_7.html) for strtotime() (http://www.php.net/strtotime) if you like.
If it is numeric you could use mktime (which I should have started with... it's 2AM so I can forget stuff)

date('Y M d h:i:s', mktime(0, 0, 0, $m, $d + 30, $y));
