smarty and date - smarty

Question

i get date with: {$smarty.now|date_format:'%Y-%m-%d %H:%M:%S'}
But how get 20 day after?
If now: 2010 05 05 12:12:12, I wish to show 2010 25 05 12:12:12

Answer 1

{$smarty.now} is a simple timestamp (number of seconds since 1970). So you can just add as many seconds to it as you need:
{$smarty.now+20*24*60*60|date_format:'%Y-%m-%d %H:%M:%S'} //+20 days
This works in Smarty3, if not in older versions then you might need to do the math with {assign} and/or {math} directives.

Answer 2

Use the strtotime() php function and assign your variable to smarty. Something like this:
<?php
$later = strtotime('+20 day');
$smarty->assign('later', $later);
?>
Then in the template:
{ $later|date_format:'%Y-%m-%d %H:%M:%S'}

Answer 3

You can use strtotime() directly as a modifier.
{"+20 days"|strtotime|date_format:"Y/m/d"}

Answer 4

In newer versions of smarty it will strtotime any string you prepend
I.e. instead of doing {$smarty.now|date_format:'%Y-%m-%d %H:%M:%S'} you can also do {"now"|date_format:'%Y-%m-%d %H:%M:%S'}
To get the date 20 days from now, you can do:
{"+20 days"|date_format:"%Y-%m-%d"}

Answer 5

{assign var="iItemOne" value=$smarty.now}
{assign var="iItemTwo" value=1296000} //60*60*24*15-> for 15 days
{assign var="iSum" value=$iItemOne+$iItemTwo}
{$iSum|date_format:'%Y-%m-%d %H:%M:%S'}

$one= date("Y-m-d", strtotime(date("Y-m-d", strtotime('$add dynamic date variable')) . " + 1 day"));
$this->smarty->assign('one',$one);
